Hi mate I am Yamaha man myself but thought this may help I get this question often for YZ yamahaa if your cam is installed you will never get the chain over it on - YZ at least, you need to place chain over cam sprocket at same time as installing the cam before cam is locked in (and even that is very tight fit) especially if brand new cam chain is being fitted as well cheers mate not sure this helps but it sounded familiar good luck

I NEED TIMING CHAIN DIAGRAM FOR VQ20 NISSAN SERFIRO 1999


Instructions
  1. Remove Your Timing Chain
    • 1 Check your owner's manual for the recommended mileage for replacing your timing chain. Replacement for a Nissan Altima is 60,000 miles.
    • 2 Locate the timing chain. Replace it if the automatic chain adjuster (also known as the tensioner) is damaged or worn.
    • 3 Drain the cooling system and disengage the negative battery cable. Undo the spark plug wires and set the No. 1 piston at "Top Dead Center" (TDC) of the compression stroke.
    • 4 Disconnect the engine undercover, vacuum and fuel hoses, harness and connectors, drive belts, power steering reservoir, alternator and bracket, upper radiator hose, air duct, front exhaust tube, intake manifold collector supports, collector and exhaust manifold and the distributor.
    • 5 Prop up the oil pan and take out the front engine mounting, the valve cover, camshaft sprockets, cam bearing caps, camshafts, cylinder head bolts (reverse the installation order), cam sprocket cover, upper chain tensioner, chain guides and chain, idler sprocket bolt, cylinder head, intake manifold and cylinder head gasket and the steel oil pan.
    • 6 Place a steel cutter between the steel and aluminum oil pans. Slip the cutter around the oil pan's edge. Disengage the steel oil pan, baffle plate, oil strainer and the front tube.
    • 7 Secure the car on jack stands and place a seal cutter in between the oil pan and cylinder block. Slip the cutter around the oil pan's edge.
    Install Your Timing Chain
    • 8 Reconnect the crankshaft sprocket, oil pump drive spacer, idler sprocket and lower timing chain. Position the lower timing chain on the sprockets and line up the mating marks.
    • 9 Rub on an unbroken bead of liquid gasket and put in a new front cover and oil seal. Secure the bolt at 105 to 112 foot pounds (142 to 152 Nm).
    • 10 Eliminate any old material from the pan and cylinder block mounting surfaces. Rub on a 3.5 to 4.5mm bead of liquid gasket over the oil pan and cylinder block.
    • 11 Attach the upper timing chain to the idler sprockets and secure the cylinder head bolts.
    • 12 Refill the cooling system and add clean oil in the engine.
    • 13 Hook up the negative battery cable and any other disconnected parts or items. Start the engine and look for leaks.
Tips & Warnings
  • Procedures for replacing timing chains in Nissan Altimas vary slightly depending on engine size.
  • Make sure the new timing chain matches the chain you are removing.

Xv535 cam chain jumped one tooth on cog,tensioner is fine ,so how did it happen,and how can i fix it


If all cogs and bearings are fine and that the chain tension is at specification then it should not be possible for the chain to ever jump a tooth. The amount of movement required by the chain to jump a tooth is considerable. I have only ever seen this as a result of an oversight when re-installing the chain after doing upper cylinder head work such as gasket replacement. Some models of vehicles with V6 engines that integrate the timing belt with driving the coolant pump can sometimes jump a tooth if the pump bearing fails. I would again check the chain tension once the timing chain is re-installed, even without tools you should be looking for a chain that is obviously taught. Not piano wire taught as this will lead to early failure but certainly one without any slackness or rattle. I have little experience of bike engines but the principles are the same

How do I line up my marks on cam shaft and flywheel to set timing


Hi mate didn't get any info on what bike you are timing but this procedure is simular for most and is specific for WR YZ 250 426 and 450

set piston to TDC (top dead centre) this can be done by spinning the fly around until you can see the (i) mark stamped on the flywheel line up with the marks on the inspection plug hole (engine case) good idea to probe the cylinder through the spark plug hole to confirm the flywheel mark is correct (I have seen several 426) where the TDC mark does not give accurate TDC on piston so worth second guessing this process.


once TDC is set do not allow piston to move from this point on - starting with the exhaust cam with no slack on the cam chain the dot stamped on the cam sprocket should align with the face of head with the cam lobes pointing outward roughly 45 degrees towards the front wheel when this in place

you do the same with intake cam except the cam lobe will face opposite direction outward and the should be a dot aligning to the head


double check before you go further that when you put your finger in the chain tension hole and you tension the cam chain that when all slack is taken from the cam chain that your dots on both cams align with head face and that you still have piston at TDC if all checks out then this is timed set correct so torque all the cam caps back up install chain tensioner and the recheck all fly wheel marks are in correct position and piston is at TDC and the dot on each cam sprocket aligns to the head if it doesn't then re do the process

don't be surprised if this takes a few attempts as it takes the best of us usually at least two attempts to get all marks to align correctly thats why best to check and double check before you bolt it all down then you can adjust just by lifting one cam out and moving one tooth either direction


You have little room to play with and when you start putting chain on the cam sprockets you will find very little extra chain length to play with you may need to wiggle tug and pull both cams together to get them back in each time but go slow and gentle they do go in they just need to be encouraged


I happy to elaborate on any point if you need - good luck

I would like to have a diagram of the timing comfiguration of a 2002 dodge intrepid 2.7 .....i am very interested in the timining marks for the camshafts


Hi, this engine uses plated links in the chain to match marks on the gears. See figure and installation procedure below. Let me know if you have any questions and thanks for using FixYa.

jturcotte_614.gif
    1. Install the timing chain by performing the following procedure:
    1. Verify that the crankshaft sprocket timing mark is aligned with the mark on the oil pump housing.
    2. Place the left side primary timing chain sprocket onto the chain, while aligning the timing mark on the sprocket to the 2 plated links on the chain.
    3. Lower the chain with the left sprocket through the left cylinder head opening.
    4. Loosely position the left camshaft sprocket over the camshaft hub.
    5. Align the plated link to the crankshaft sprocket timing mark.
    6. Position the timing chain around the water pump drive sprocket.
    7. Align the right camshaft sprocket timing mark to the plated link on the timing chain and loosely position the sprocket over the camshaft hub.
    8. Verify that all the plated links are aligned to their proper timing marks.
    1. Install the left lower timing chain guide and tensioner. Torque the bolts to 21 ft. lbs. (28 Nm).
      NOTE Inspect the timing chain guide access plug O-rings before installing. Replace damaged O-rings as necessary.
    2. Install the timing chain guide access plug to the left cylinder head and torque to 15 ft. lbs. (20 Nm).
      NOTE To reset the timing chain tensioner, oil will first need to be purged from the tensioner.
    1. Purge oil from the timing chain tensioner using the following procedure:
    1. Remove the tensioner from the tensioner housing.
    2. Place the check ball end of the tensioner into the shallow end of the Tensioner Resetting Special tool 8186.
    3. Using hand pressure, slowly depress the tensioner until oil is purged from the cylinder.
    4. Reinstall the tensioner into the tensioner housing.
    1. Reset the timing chain tensioner using the following procedure:
    1. Position the cylinder plunger into the deeper side of the Tensioner Resetting special tool 8186. Apply a downward force until the tensioner is reset.

    WARNING

    Ensure that the tensioner is properly reset. The tensioner body must be bottomed against the top edge of the Tensioner Resetting Special tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.

    1. Install the chain tensioner into the right cylinder head.
    2. At the right cylinder head, insert a 3 / 8 in. square drive extension with a breaker bar into the intake camshaft drive hub. Rotate the camshaft until the camshaft hub aligns with the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and torque to 21 ft. lbs. (28 Nm).
    3. Turn the left camshaft by inserting a 3 / 8 in. square drive extension with a breaker bar into the intake camshaft drive hub. Rotate the camshaft until the camshaft hub aligns with the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and torque to 21 ft. lbs. (28 Nm).
    4. If necessary, rotate the engine slightly clockwise to remove any slack in the timing chain.
    5. To arm the timing chain tensioner: Use a flat-bladed prytool to gently pry the tensioner arm towards the tensioner slightly. Then, release the tensioner arm. Verify the tensioner extends.
    6. Inspect and replace the timing chain cover gasket and oil seal.
    7. Apply a 1 / 8 in. (3mm) bead of sealer at the parting line of the oil pan and engine block.
      NOTE When installing the timing cover, guide the seal over the crankshaft to prevent damage to the seal-s lip.

    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

    $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.

    Check the vehicle manual for recommended mileage for replacing the timing chain.Locate the timing chain,you will need to replace it if the automatic chain adjuster "also known as the tensioner " is damage or worn.Drain the cooling system and disengage the negative battery cable.Undo the spark plug wires and set the No.1 piston at Top Dead Center ( TDC ) of the compression stroke. Disconnect the engine undercover,vacuum and fuel hoses,harness and connectors,drive belts, power steering reservoir,alternator and bracelet,upper radiator hose and,air doct,front exhaust tube,intake manifold collector supports,collector and exhaust manifold and distributor.Prop up the oil can and take out the front engine mounting,the valve cover and camshaft sprockets,cam bearing caps and camshafts,cylinder head bolts, cam sprocket cover,upper chain tensioner,chain guide and the chain,idler sprocket bolt,cylinder head,intake manifold and cylinder head gasket and the steel oil pan. Place a steel cutter between the steel and aluminum oil pans.Slip the cutter around the the edge of the oil pan and disengage the steel oil pan,baffle plate,oil strainer and front tube. Secure the vehicle on jack stands and place a seal cutter between the oil pan and the cylinder block,slip the cutter around the edge of the oil pan.

    Judging by your previous questions,I think this is the info you need.
    Setting cam timing with stock cams is relatively easy using the punch mark on the cam gears For stock timing, the punch marks at 9 O'clock on the exhaust cam and at 3 O'clock on the intake cam should align with the top of the head. If stock timing is altered the exhaust cam punch mark will either be one tooth above or one tooth below the top of the head.

    1. Take out tensioner.
    2. Remove both plugs from shifter side of crankcase, the center plug to turn, the 11:00 plug to locate the 'I' (not the H) in.
    3. Use a ratchet on end of crankshaft (through center plug) and zip tie ratchet to footpeg with the I lined up in the timing plug hole.
    4. With the intake cam (rear one) pointing straight back, align the punch mark on the backside of the intake cam sprocket with the top of the head. Since the slack in the timing chain is in the back, if it doesn't align exactly right at the top of the head, err slightly high. Zip tie chain to intake sprocket.

    1. Remove exhaust cam, count 12 links (where sprocket teeth will go) from the punch mark on the top of the intake cam and mark that position on the chain with something noticeable (use a Sharpie). Hold the exhaust cam close the to intake cam with the exhaust cams pointing horizontally to the front of the bike. With the exhaust cam in this position, there will be a punch mark at the top. Put the tooth above this punch mark in the chain link you marked that was 12 or 13 over. Zip-tie the chain to the exhaust cam.
    2. Reseat exhaust cam. The punch mark on the left side of the exhaust sprocket will align with the top of the head. It will be one link high. Go back and check that the I is still centered in the timing plug hole
      1. the intake cams point back
      2. the exhaust cams point frontward
      3. the rear punch mark on the intake is aligned or slight high with the top of the head
      4. the front punch mark of the exhaust sprocket is aligned with the top of the head
    3. Bolt and torque exhaust cam, torque intake if you've had it off.
    4. Install chain tensioner (wind it up, hold the screwdriver with two hands, use the third hand to put hold tensioner in place, and fourth hand to bolt it up, then release screwdriver and put end bolt in it.
    5. Remove zip ties on intake sprocket, exhaust sprocket, and ratchet holding TDC. Remove ratchet and replace both plugs.
    6. Put on valve cover and two hoses, reinstall tank and seat and go riding.

    Changing a head gasket on a 1984 rodeo 2000 g200 kb28 with a sohc. How do i take off the timing chain?


    there is a special tool. it holds the chain against the hydraulic tensioner and on the cam sprocket. you need this to prevent tensioner from loosing its prime and keep the timing from moving. once tool is in place remove bolt holding cam sprocket and you lift head off leaving chain and sprocket in place.
