Has anyone else embarked on this journey recently?
My cams are in with the adjustable gears on and the motor has been started as per posts elsewhere.
The guys have seemingly gone to some amazing lengths to ensure the install was spot on...
===Updated===
- Remove the crank pulley & front engine covers
- Remove the timing belt, tensioners, rocker cover & cams from the engine.
- Identify for replacement & order new OEM timing belt, tensioner & idlers.
- Change over all the valve springs.
- Bleed down the lifters & fit cams to measure dry lash.
- Identify that the dry lash is wrong & shims are required.
- Investigate & source shims for engine, Liaise with customer & order new shims.
- 12.0mm OD x .53 mm thick shims (qty. 24) required to compensate for dry lash measurement
- Fit shims & refit the cams
- Check the cams specifications & liaise with client.
- Fit the front bank cams & gears
- Machine head to suit cam wheels supplied by customer & check the clearance. Repeat until sufficient clearance obtained.
- Fit the rear bank cams & gears
- Install the cam gears & torque to specifications.
- Fabricate a dial gauge stand & check true top dead centre.
- Set up the crank wheel & pointer.
- Fit the cam belt idlers & tensioner.
- Fit the timing belt to the engine & line up as per the supplied cam gear specifications.
- Setup the dial indicator and check cam timing front and rear banks.
- Remove the belt & reset with new markings & check.
- Repeated the process until cams were dialled correctly.
- Movement of gears on belt required, in addition to adjustment of gears themselves.
- Repeat this process for both cams on both banks.
- Remove & refit belt and adjust gears until cam numbers within spec.
- MD376687 (Qty. 4) Lifters - 6A13. Weld & Use as solid lifter tools for cam timing
- Refit the front timing covers, pulleys & auxiliary belts.
*Note: The cam gears were not only two teeth off on the exhaust cam front bank, they were also two teeth out (in the opposite direction) on the intake cam front bank. Additionally they were also three teeth out on both cams (in opposite directions) on the rear bank too. Intake cam centres of 109Deg ATDC and exhaust cam centres of 112Deg BTDC.
============
Proofs in the pudding though, results to follow early next week (Galant finally saw it's first dyno time this afternoon with the new mods).
