1996 GA15 head removal - idler sprocket?How to support it to lift head off.

Need to unbolt it to lift head. Must keep lower chain engaged. How do I support it? Not much clearance. Do I need to loosen lower chain tensioner to get it off the shaft?

    Sorry, this is a Nissan Pulsar 1.5lt. Idler sprocket has two gear wheels. one for top chain (disconnected) and one carries the lower chain which I must keep engaged with crankshaft. Seems I must unbolt it from the head and attach a supporting wire around the top of the sprocket and chain, hold it up, lift the head up and transfer my hold on the wire to underneath the head. Remove head and put blocks under the sprocket. Is that it? I'm worried about clearance pulling the sprocket off the shaft - only about 1/2 inch to the back edge of the head cut-out. Will it be clear of the shaft by then? I presume I'll have to take out the lower chain tensioner first. I'm using a Haynes manual for GA16 (same motor basically) but it does not explain this. Thanks, Mike.

SOURCE: Trying to put timing chain

no adjustment neccesary. There is a timing chain tensioner, which you will simply push back in to its body. once you do that, there should be a small hple somewhere on the body of the tensioner. That' sthere so you can piut a paper clip into it to keep the tensioner from coming out. Once you lock that in place you can remove the tensioner and than the timing chain.Once you get it all back together, just pull back on the pin and the tensioner will come out and put tension on the chain. good luck.

here ill do a paste from JUST install PART chapter.
you are doing ALL THAT book free, REALLY?
https://www.techauthority.com/en-US/Pages/Home.aspx

  1. Using a vise, lightly compress the secondary chain tensioner piston until the piston step is flush with the tensioner body. Using a pin or suitable tool, release ratchet pawl by pulling pawl back against spring force through access hole on side of tensioner.
  2. While continuing to hold pawl back, Push ratchet device to approximately 2 mm from the tensioner body. Install Special Tool 8514 lock pin into hole on front of tensioner. Slowly open vise to transfer piston spring force to lock pin.
  3. Position primary chain tensioner over oil pump and insert bolts into lower two holes on tensioner bracket. Tighten bolts to 250 inch lbs. (28 Nm).
  4. Install right side chain tensioner arm. Install Torx®bolt. Tighten Torx®bolt to 250 inch lbs. (28 Nm). CAUTION The silver bolts retain the guides to the cylinder heads and the black bolts retain the guides to the engine block.
  5. Install the left side chain guide. Tighten the bolts to 250 inch lbs. (28 Nm).
  6. Install left side chain tensioner arm, and Torx®bolt. Tighten Torx®bolt to 250 inch lbs. (28 Nm).
  7. Install the right side chain guide. Tighten the bolts to 250 inch lbs. (28 Nm).
  8. Install both secondary chains onto the idler sprocket. Align two plated links on the secondary chains to be visible through the two lower openings on the idler sprocket (4 o'clock and 8 o'clock). Once the secondary timing chains are installed, position special tool 8429 to hold chains in place for installation.
  9. Align primary chain double plated links with the timing mark at 12 o'clock on the idler sprocket.
  10. Align the primary chain single plated link with the timing mark at 6 o'clock on the crankshaft sprocket.
  11. Lubricate idler shaft and bushings with clean engine oil. NOTE The idler sprocket must be timed to the counterbalance shaft drive gear before the idler sprocket is fully seated.
  12. Install all chains, crankshaft sprocket, and idler sprocket as an assembly . After guiding both secondary chains through the block and cylinder head openings, affix chains with a elastic strap or equivalent. This will maintain tension on chains to aid in installation. Align the timing mark on the idler sprocket gear to the timing mark on the counterbalance shaft drive gear, then seat idler sprocket fully . Before installing idler sprocket bolt, lubricate washer with oil, and tighten idler sprocket assembly retaining bolt to 25 ft. lbs. (34 Nm). NOTE It will be necessary to slightly rotate camshafts for sprocket installation.
  13. Align left camshaft sprocket "L" dot to plated link on chain.

2001 , no such ani-mule !
"Introduced for the 2002 model year as a replacement for the Cherokee (XJ),"
you meant manufactures date not model and reg. date. sure.
2002 !
3.7L V6 (cop spark ) chain drive cams....
timing ( cam or spark?)
"Ignition timing is controlled by the Powertrain Control Module (PCM). No adjustment is possible"
so Cam timing (alldata.com covers this in detail)
why not post the context, Im doing what.?
im doing a 60k belt swap
or it slipped. or think id did.
or just put in a new head or cam? see , context is 100% important.
im here, going to there.....
im on line, and it shows 4 engines, i think that is wrong, but...

you must be asking chain cam sprocket timing.
im at alldata.com (or FSM)
there are 37 install steps, im not sure what step you want me
to pluck out. but here is my guess. step 8 ,9,10
  1. Install both secondary chains onto the idler sprocket. Align two plated links on the secondary chains to be visible through the two lower openings on the idler sprocket (4 o'clock and 8 o'clock). Once the secondary timing chains are installed, position special tool 8429 to hold chains in place for installation.

  2. Align right camshaft sprocket "R" dot to plated link on chain.

step 15/16
  1. Remove Special Tool 8429, then attach both sprockets to camshafts. Remove excess oil from bolts, then Install sprocket bolts, but do not tighten at this time.

or get a real FSM.
its nothing trivial.

in fact get the book before the job. so are perpared.

How do i set camshafts on 1999 duvil northstar


Remove camshaft covrs
Remove front cover
Remove or fully retract all three timing chain tensioners
Remove oil pump
Primary and secondary chain guides should remain in place. Rotate crankshaft until sprocket drive key is at about 1 o'clock position.
Set crankshaft and intermediate shaft sprockets into primary drive chain with their timing marks asjacent to each other.
Install crankshaft and intermediate sprockets over their respective shafts. Rotating crankshaft as necessary to engage crankshaft key in sprocket without changing the timing mark relationship.
Install Flywheel Holder Tool (J-39411) to lock crankshaft in position. Install intermediate shaft sprocket retaining bolt and torque to specifications.
Route secondary chain for left cylinder head over inner row of intermediate shaft teeth.
Route secondary drive chain over chain guide, and install exhaust cam sprocket to chain so camshaft drive pin engages the sprocket notch marked "LE" (Left Exhaust).
There dhould be no slack in the lower section of the chain, and the camshaft drive pin must be perpendicular (90 degrees) to the cylinder head surface.
Install the intake camshaft sprocket into the chain so the sprocket notch marked "LI" (Left Intake) engages camshaft drive pin, while drive pin remains perpendicular to the head face. Minor adjustments can be made to camshaft position to get pin to engage by using a wrench on the hex cast into the camshaft.
Install sprocket retainer bolts and torque to specification.
Repet steps as above to install the right secondary chain to the right camshafts. The right camshaft sprockets are marked "RE" and "RI". In addition, the RE sprocket must contain the camshaft position sensor pickup.

I changed water pump in 1998 maxima !! Can you help me identify the location of the timing mark on crankshaft sprocket ??


Remove the three bolts retaining the upper chain guides and lift it from the cylinder head.

To allow access to the camshaft sprocket bolts, unbolt the upper timing chain cover and carefully pry the cover away from the cylinder head

Set the number one piston at TDC on the compression stroke by aligning the timing marks on the crankshaft damper.

Fig. 6: The number one cylinder is at TDC when the timing marks are aligned as shown (clikc image for zoom)



Check that the mating marks on the sprockets are aligned as shown in the illustration. If not, the crankshaft should be rotated another 360°.

Fig. 7: It may be helpful to paint marks on the chain and sprockets if the marks are not easily visible



Remove the camshaft position sensor. Mark the position of the sensor before removal to help keep the ignition timing correct.

Hope this helps.

INSTALLATION
  1. Using a vise, lightly compress the secondary chain tensioner piston until the piston step is flush with the tensioner body. Using a pin or suitable tool, release ratchet pawl by pulling pawl back against spring force through access hole on side of tensioner. While continuing to hold pawl back, Push ratchet device to approximately 2 mm from the tensioner body. Install Special Tool 8514 lock pin into hole on front of tensioner. Slowly open vise to transfer piston spring force to lock pin (Resetting Secondary Chain Tensioners).
  2. Position primary chain tensioner over oil pump and insert bolts into lower two holes on tensioner bracket. Tighten bolts to 28 N·m (250 in. lbs.). CAUTION: Overtightening the tensioner arm torx® bolt can cause severe damage to the cylinder head. Tighten torx® bolt to specified torque only.
  3. Install right side chain tensioner arm. Apply Mopar® Lock N, Seal to torx® bolt, tighten bolt to 17 N·m (150 in. lbs.). NOTE: The silver bolts retain the guides to the cylinder heads and the black bolts retain the guides to the engine block.
  4. Install the left side chain guide. Tighten the bolts to 28 N·m (250 in. lbs.). CAUTION: Overtightening the tensioner arm torx® bolt can cause severe damage to the cylinder head. Tighten torx® bolt to specified torque only.
  5. Install left side chain tensioner arm. Apply Mopar® Lock N, Seal to torx® bolt, tighten bolt to 17 N·m (150 in. lbs.).
  6. Install the right side chain guide. Tighten the bolts to 28 N·m (250 in. lbs.).
  7. Install both secondary chains onto the idler sprocket. Align two plated links on the secondary chains to be visible through the two lower openings on the idler sprocket (4 o'clock and 8 o'clock). Once the secondary timing chains are installed, position special tool 8515 to hold chains in place for installation (Installing Secondary Timing Chains on Idler Sprocket).
  8. Align primary chain double plated links with the timing mark at 12 o'clock on the idler sprocket. Align the primary chain single plated link with the timing mark at 6 o'clock on the crankshaft sprocket (Timing Chain System).
  9. Lubricate idler shaft and bushings with clean engine oil.
  10. Install all chains, crankshaft sprocket, and idler sprocket as an assembly (Installing Idler Gear, Primary and Secondary Timing Chains). After guiding both secondary chains through the block and cylinder head openings, affix chains with a elastic strap or the equivalent, This will maintain tension on chains to aid in installation. NOTE: It will be necessary to slightly rotate camshafts for sprocket installation.
  11. Align left camshaft sprocket “L” dot to plated link on chain.
  12. Align right camshaft sprocket “R” dot to plated link on chain. CAUTION: Remove excess oil from the camshaft sprocket bolt. Failure to do so can result in over-torque of bolt resulting in bolt failure.
  13. Remove Special Tool 8515, then attach both sprockets to camshafts. Remove excess oil from bolts, then Install sprocket bolts, but do not tighten at this time.
  14. Verify that all plated links are aligned with the marks on all sprockets and the “V8” marks on camshaft sprockets are at the 12 o'clock position (Timing Chain System). CAUTION: Ensure the plate between the left secondary chain tensioner and block is correctly installed.
  15. Install both secondary chain tensioners. Tighten bolts to 28 N·m (250 in. lbs.). NOTE: Left and right secondary chain tensioners are not common.
  16. Before installing idler sprocket bolt, lubricate washer with oil, and tighten idler sprocket assembly retaining bolt to 34 N·m (25 ft. lbs.).
  17. Remove all locking pins (3) from tensioners. CAUTION: After pulling locking pins out of each tensioner, DO NOT manually extend the tensioner(s) ratchet. Doing so will over tension the chains, resulting in noise and/or high timing chain loads.
  18. Using Special Tool 6958, Spanner with Adaptor Pins 8346, tighten left (Tightening Left Side Camshaft Sprocket Bolt) and right (Tightening Right Side Camshaft Sprocket Bolt). camshaft sprocket bolts to 122 N·m (90 ft. lbs.).
  19. Rotate engine two full revolutions. Verify timing marks are at the follow locations:
  20. Lubricate all three chains with engine oil.
  21. After installing all chains, it is recommended that the idler gear end play be checked (Measuring Idler Gear End Play). The end play must be within 0.10–0.25 mm (0.004–0.010 in.). If not within specification, the idler gear must be replaced.
  22. Install timing chain cover (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT / CHAIN COVER(S) - INSTALLATION) and crankshaft damper (Refer to 9 - ENGINE/ENGINE BLOCK/VIBRATION DAMPER - INSTALLATION).
  23. Install cylinder head covers (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - INSTALLATION). NOTE: Before installing threaded plug in right cylinder head, the plug must be coated with sealant to prevent leaks.

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.
