Remove the spark plug then put the piston at Top Dead Center compression. Look at the position of the timing marks on one side of the cam, parallel with the gasket surface. Remove the cam as you described.

How do I take the cam sproket off a 2002 suzuki xl7? And what is the screw that id embedded infront of the head near the alt belt? Suzuki not cool.


correct suzuki does suk and is now officially in usa BUGGED OUT.
like, ISUZU< YUGO, DAEWOO< etc.
no job stated, what are you doing? polishing cam lobes? what?
bad water pump
bad chain and friends, ? guides, etc.
bad head?
bad sprocket due some one ignoring bad chain?
what? what is the job, or what is the damage, help the helper
know why you are here, is like 100 points to a good answer
no?

first off never work in this complex engine lacking the FSM book.
the real book (factory) is only 4 bucks to read, is that not worth causing damage"?????? see last link on this page.
I post this so all H2x engines, can be serviced, in this area.
which cam? sprocket, (left or right bank)??????????
Ok first off what engine is there, no photos posted, so are we to guess that,? or state this.
My guess is you cant get the bolt off, on the end if a cam.
RIGHT?>
we have posted chain swaps on many suzuki engines here.
J20s, H25,h27, etc.... this car sold in usa has the V6 mostly
H25 and H27 and are near same.
the cam shafts must be locked on all DOHC./SOHC engines first.
so the Sprocket wheel can be removed. (or it just spins.)
newtons laws and all that on relative motions...
chain drive, V6 engine. it is, H20 and up world wide, class engines.
there are 2 ways to do this, (3 with hacks)
1: buy the cam locker tool use that.
2:some suzuki have a hole in the cam, that you slide a dowel rod in and it lock.s
3: hack we, find something behind said sprocket say a freeze plug
and put a pry bar there and then off the nut. sprocket.
i can only presume front cover off, and valve covers off.
so that puts you where. it the pages, of sprocket swaps.
you then ask a 2nd question, about some screw then fail to post a photo of it, the is only a 3 bolt clamp on the alternator mount there. so..../?? , I cant guess, what you see or touch, lacking PHOTOS.
btw, I own the book but sold the car, so.... know it well.
the engine is half Mazda/Suzuki, a joint design. (history)
here are the many chain service web page links I keep. tract of.
http://bbs.zuwharrie.com/content?topic=45886.0

the book link, here here from SUZUKI's SITE its real this is not junk clone book its 4 bucks to read,


JUST $4 bucks to read ALL DAY. posted now 100s of times.
search much,
even use google " Cam chain H27 engine."

https://suzukipitstopplus.com/Products/10182-2007-xl7-service-manual.aspx

last but best in the book in the chapter on cam shaft swap.
step 7. if you had looked at the cam, you;d have seen
the cast in lockup device, (not a hole like seen on SOHC)
but a BOSS for a spanner. best is always look first.
I'd bet it works on SUZUKI H2x engines V6. on both banks.
idle sprockets are another matter as is crank sprocket.

Procedure for chaincase removal front sprocket inspection 2002 1200s gfs


Remove the gearbox sprocket cover, this may mean undoing the gear lever, First put the bike in gear. This will lock the sprocket so you can undo the securing nut, you will also need to loosen the rear axle to allow the chain to be taken off the sprocket. Then remove the sprocket, refit is the same process in reverse. I would suggest you change the complete set (front & rear sprockets and the chain) that way you only have to take it to bits once. And it will also mean the chain lasts longer as the wear will be the same at both ends.

How to change the belt


First, lay the saw on it's side with the blade facing up.
you should see an access panel at the base of the blade. Remove the screws and the panel. This should reveal two hat nuts and the chain drive sprocket. Loosen the two hat nuts, allowing you to slide the chain bar backwards and remove the old chain. Loop the new chain around the bar and drive sprocket, paying special attention to the direction of rotation of the chain. the cutting surface of the teeth should face the handle of the saw on the BOTTOM side of the blade. Pull forward on the bar and HAND-TIGHTEN the hat nuts. This will allow you to adjust the blade tension. Pull outward on the chain at the cnter of the bar. Slide the back and forth until you acheive about 1/4 inch gap between the chain and the bar. Once you are satisfied with the tension, tighten the hat nuts with a wrench and replace the cover and screws. Just pay close attention to the tension of the chain. Too loose and it will skip off, too tight and will bog down the motor and overheat.

I have a yamaha gladiator ss purchased on 1 june 2009. My bike makes a very hollow and loud sound and has poor pick up as compared to other gladiators, also its not at all smooth to drive. It behaves like...


Increase in idle is usually a vacuum leak in the intake or carburetor. The poor acceleration can be a stretched timing chain that jumped a tooth on the cam sprocket or the slide in the carburetor isn't raising as it should due to bad diaphragm at the top of the piston if yours has one. Easiest way to check the carb is to remove the intake boot on the carb and watch the slide in the carb when you rev the engine. If it isn't rising up quickly when you pull full throttle then you have either an air leak in front of the carb or the slide is sticking/diaphragm is bad. There is a TDC mark on the flywheel on the left side of the engine usually found by removing a small plug or a round cover over the flywheel. TDC mark aligns with notch or pointer then remove cover on the head on left side to check the timing chain sprocket . There is a mark on the head that aligns with a mark on the sprocket at TDC (top dead center). If the timing mark is off to the right on the sprocket the chain has jumped time. You have to remove the timing chain tensioner on the back of the cylinder (two screws) then you will have enough slack to jump the chain back on the sprocket . Then replace the tensioner , release the tensioner by loosening the lock nut on top of the shaft or lock screw then retighten it. Do not overtighten or you will damage the slide inside that applies pressure to the chain. Recheck your timing marks. Sometimes the exhaust valve is bent when the chain jumps. You can check compression with a gauge or by putting your finger over the spark plug hole tightly and turning the engine over with the starter with the spark plug grounded . You must ground the spark plug or it can fry the ignition system. Good luck!

Setting of timing chains


Get Ford timing tool kit, part = otc-6488 (For about $119 USD on eBay)

4 timing chains (3 front including the optional balance shaft chain + 1 back)

2 cam guides (1 front + 1 back)

2 oil tensioners (1 front + 1 back)

1 jackshaft tensioner (1 front)

1 jackshaft guide/cassette (1 front)

1 balance shaft tensioner (1 front) (will probably be ok, so dont replace it)

1 balance shaft guide (1 front) (will probably be ok, so dont replace it)

new sprockets + bolts + gaskets etc.

new spark plugs + throttle body cleaner + lithium grease spray + oil change

head gaskets


some of these parts (the front stuff) can be obtained as a primary timing chain rattle noise kit Part# = 2u3e-6d256-** ab for 4*4 & bb for 2*4.

The kits also have later part numbers for us$ 76 @ http://www.fordpartsonline.com


My parts order (without the balance shaft stuff) was:

$76.04 KIT-TENSIONER TIMING 2u3e-6d256-ab

$47.93 Engine, Camshaft and timing, Timing chain, TIMING CHAIN, Explorer, Mountaineer, Rear - 4.0L SOHC - 4.0L SOHC

$57.36 Engine, Camshaft and timing, Chain guide, CHAIN GUIDE, Explorer, Mountaineer, Jackshaft To Cam - 4.0L SOHC - 4.0L SOHC

$28.93 Engine, Camshaft and timing, Tensioner, TENSIONER, Explorer, Mountaineer, Upper - 4.0L SOHC - 4.0L SOHC

Its worth mentioning that this procedure is not enjoyable at all and should be undertaken with at least 8 full days to completion (I recon you could do it in half the time the second time).

It is basically on entire engine re-build with both heads off and the engine out of the vehicle.

It is not possible to do the rear chain or sprocket with the engine in the car as the flywheel needs to come off + at least 1 head, but it is possible to do the front primary chain and or front cam chain with the engine in the car.

You will be a ford exploder and timing expert after you do this - the main reason should be the love of your American built vehicle. Its a solid car - except for the plastic guides!

Disclaimer Note: This is how i successfully did the job, but i am not a ford mechanic and don't hold me responsible if this does not work for you.
Timing Overview

A Small Sprocket on the crank turns a larger (2 to 1 ratio) jackshaft sprocket that is in turn connected front & back to the 2 camshafts.

Thus a 360o turn of the crank will turn both the camshafts 180o.

Firing order is 1-4 2-5 3-6, Right side numbers 1,2,3. Left Side = 4,5,6.

At TDC pistons 1 & 5 are fully raised, thus 1 is about to spark & 5 is evacuated.

The engine will turn freely (no piston to valve contact) with the cams 180o out, it will even run (roughly) with 1 out 180o, any other settings may cause major damage to the valves.

The 2 cam shafts come with timing markings, "yes" real timing marks that anyone can use (even without special tools) to ensure correct timing.

The way to time it is to ensure both the off centre cam shaft slits are level/flat with the head.

With the engine at TDC both the cams need to have the off centre slot in the same position either up and level or down and level.

It is super critical that both the camshafts are 100% in sink with each other, i.e. not a few degrees off, the engine computer can compensate for crank timing but not engineering failure.

Be warned the camshafts can turn easily fast & hard by themselves as a few springs are compressed at TDC, I got my finger jammed and its still healing + if the engine is not at TDC you may damage a valve.

Now heres the hard thing that you will need special tools for - if you need to change the timing, you will need to be able to undo the cam sprocket bolt on both cams & these are done up real tight.

There is a tool that you attach that has 2 pencil thick shafts that fit into the sprocket and prevent it from turning - then you need to put about 90Nm of force on the bolt (remember the rear one if LHT)

For the $money$, its well worth getting yourself the tool kit - it will save you hours in the long run. Search eBay for otc-6488 should be US $119 - then sell them again for say $100.

There is also a tool version of the oil tensioner in the kit that screws right in and puts the correct amount of force on the chain + guide, to enable you to do up the cam bolt with the chain and sprocket in the right spot on the cam.

How do i reset the timing in a 1997 z24 Chevrolet Cavalier 2.4 twin cam? Where are the timing marks on the cam gears?


2.3L and 2.4L Engines Before attempting to remove the timing chain, read the entire procedure.
  1. Disconnect the negative battery cable.
  2. Remove the timing chain front cover, as outlined earlier in this section.
  3. Rotate the crankshaft clockwise, as viewed from the front of engine/normal rotation, until the camshaft sprocket timing dowel pin holes line up with the holes in the timing chain housing. The crankshaft sprocket keyway should point upwards and line up with the centerline of the cylinder bores. This is the "timed'' position. Fig. 8: The chain must be in the "timed'' position - 2.3L and 2.4L engines 87953108.gif
    Fig. 9: Remove the timing chain guides 87953109.gif

  4. Remove the timing chain guides.
  5. Raise and safely support the vehicle.
  6. Make sure all of the slack in the timing chain is above the tensioner assembly, then remove the tensioner. The timing chain must be disengaged from any wear grooves in the tensioner shoe in order to remove the shoe. Slide a suitable prytool under the timing chain while pulling the shoe outward. WARNING
    Do NOT attempt to pry the socket off the camshaft or damage to the sprocket or chain housing could occur.
  7. If difficulty is encountered in removing the chain tensioner shoe, remove the intake camshaft sprocket, as follows;
    1. Carefully lower the vehicle.
    2. Hold the intake camshaft sprocket with a suitable tool and remove the sprocket bolt and washer.
    3. Remove the washer from the bolt and rethread the bolt back into the camshaft by hand. The bolt provides a surface to push against.
    4. Remove the camshaft sprocket using a three-jaw puller in the three relief holes in the sprocket.
  8. Unfasten the tensioner assembly retaining bolts, then remove the tensioner. NOTE: The timing chain and crankshaft sprocket MUST be marked before removal. If the chain or sprocket is installed with the wear pattern in the opposite direction, noise and increased wear may occur.
  9. Mark the crankshaft sprocket and timing chain outer surface for reassembly, then remove the chain.
  10. Clean the old sealant off the bolt with a wire brush. Clean the threaded hole in the camshaft with a round nylon brush. Inspect the parts for wear and replace as necessary. Note that some scoring of the chain shoe and guides is normal. To install: WARNING
    Failure to follow this procedure may result in severe engine damage.
  11. Position the intake camshaft sprocket onto the camshaft with the surface marked during removal showing.
  12. Install the intake camshaft sprocket retaining bolt and washer, tighten to 52 ft. lbs. (70 Nm) while holding the sprocket with a suitable tool. Use GM sealant 12345493 or equivalent on the camshaft sprocket bolt.
  13. Place GM tool J 36008, or equivalent camshaft aligning pins, through the holes in the camshaft sprockets into the holes in the timing chain housing. This positions the cams for correct timing.
  14. If the camshafts are out of position and must be rotated more than 1?8 turn in order to install the alignment dowel pins, proceed as follows:
    1. The crankshaft MUST be rotate 90°clockwise off of TDC in order to five the valves adequate clearance to open.
    2. Once the camshafts are in position and the dowels installed, rotate the crankshaft counter clockwise back to TDC. WARNING
      Do not rotate the crankshaft clockwise to TDC; valve or piston damage could result. NOTE: The side of the timing chain that was marked during removal must be showing when the chain is installed.

  15. Place the timing chain over the exhaust camshaft sprockets, around the idler sprocket and around the camshaft sprocket.
  16. Set the camshafts at the timed position and install the timing chain. Remove the alignment dowel pin from the intake camshaft. Using GM tool J 39579, rotate the intake camshaft sprocket counter clockwise enough to slide the timing chain over the intake camshaft sprocket. Release the camshaft sprocket wrench (J 39579 or equivalent). The length of the chain between the two camshaft sprockets will tighten. If properly timed, the intake camshaft alignment dowel pin should slide in easily. If the dowel pin does not fully index, the camshafts are NOT timed correctly and the procedure must be repeated.
  17. Leave the alignment dowel pins installed. Raise and safely support the vehicle.
  18. With the slack removed from the chain between the intake camshaft sprocket and the crankshaft sprocket, the timing marks on the crankshaft and cylinder block should be aligned. If the marks are not aligned, move the chain one tooth forward or rearward, remove the slack and recheck the marks. Fig. 10: Timing chain assembly retaining bolts - 2.3L and 2.4L engines 87953111.gif

  19. Reload the timing chain tensioner assembly to its "zero'' position as follows:
    1. Form a keeper from a piece of heavy gauge wire, as shown in the accompanying figure.
    2. Apply slight force on the tensioner blade to compress the plunger.
    3. Insert a small prytool into the reset access hole, and pry the ratchet pawl away from the ratchet teeth while forcing the plunger completely in the hole.
    4. Install the keeper between the access hole and the blade. Fig. 11: Reloading the tensioner to its "ZERO'' position, then install to the chain housing 87953110.gif

  20. Install the tensioner assembly to the timing chain housing. Recheck the plunger assembly installation, it is correctly installed when the long end is toward the crankshaft. Install the tensioner retaining bolts; tighten to 89 inch lbs. (10 Nm).
  21. Carefully lower the vehicle enough to reach and remove the alignment dowel pins. WARNING
    Severe engine damage could result if the engine is not properly timed.
  22. Rotate the crankshaft clockwise (normal rotation) two full rotations. Align the crankshaft keyway with the mark on the cylinder block and reinstall the alignment dowel pins. The pins will slide in easily if the engine is correctly timed.
  23. Install the timing chain guides, then install the front (timing chain) cover.
  24. Connect the negative battery cable.

How do you remove timing chain and re-time eng


If you need to remove the cylinder head, here's how. To remove the cam chain, you've got to also remove the left crankcase cover and flywheel.

First, you need to turn the engine over until the piston is at top dead center (TDC) of the compression stroke. Begin by removing the two round covers from the left side of the crankcase cover. Also remove the four tappet hole covers from the cylinder head cover. Turn the engine (in the normal direction of rotation) and watch the intake valves open - and close, then see that the exhaust valves open, then close. Now align the 'T' on the flywheel with the notch in the inspection hole. With all of the valves closed, the engine is at TDC of the compression stroke. Do not begin removal of the cylinder head cover until this is done - to avoid damage to the cover.

With the cylinder head cover removed, you will find two bolts attaching the cam chain sprocket to the camshaft. Turn the engine until you can get a 10mm socet onto the heads of the bolts and remove them. The sprocket will come loose and slide down onto the camshaft, enabling you to remove it an the camshaft.

Upon reassembly, set the cam timing by first setting the engine at TDC. Then, align the two marks on the cam sprocket with the gasket surface on the cylinder head. With the engine at TDC and the marks lined up, the cam timing is properly set.

well not sure exactly why it wont line up use something to turn the crank and cam to appropiate position start sliding crank gear until cam gear is touching then start to push both at same time make sure your crank key and cam pin are bothin place On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another.
