Need to know how much clearance where.
If the clutch system uses hydraulics, the flywheel should be shimmed the amount that was removed. Removing material from the flywheel moves the pressure plate away from the throwout bearing by the amount that was removed.
The flywheel for the FWD tranny should have 6 bolts. The turbo flywheel has 100 teeth and the nonturbo should have 106. The AWD flywheel should have 7 bolts.
The exhaust valves should have .005 inches of clearance, and the intake valves should have .004 inches of clearance.
Separate the engine/transmission; either pull the engine or transmission, whichever is easier for you. If it's an automatic, disconnect the torque converter from the flywheel. You can get to the bolts through the dust cover.After the engine/transmission are separated, if it's a standard, remove the pressure plate/clutch disk.pull the bolts that hold the flywheel and it should fall off in your hand.
Haynes Auto Repair Manual say's Clutch pressure plate-to-flywheel Torque should be 11 to 15 Ft-LBS Hope that helps....
refuse the clearance and request and amended clearance
A small flywheel needs to stay with the starter that goes to it. You can use either flywheel, and the block should be drilled for either starter.
On a Yamaha 1980 XS400 the valve clearance for the inlet valve should be 0.0003 inches. The valve clearance for the exhaust should be 0.006 inches.
This should be mounted with 2 bolts on the top edge of the gearbox next to the engine where part of the flywheel should be exposed I believe
Yes, on the crankshaft there should be a "slot" called a keyway, and a matching slot on the flywheel, mate a key in the slot of the flywheel and crankshaft, and then your flywheel should be timed, also on a magneto ignition system, makesure the magneto has the proper gap, called "armature air gap" usualy if you put a buossness card in there is a good starting point
You'll need to either pull the transmission or the engine to be able to get to the flywheel. Once the flywheel is exposed, it's just a few bolts and it falls off in your hands. BTW, when you put the flywheel back on, I would strongly recommend using Locktite or equivalent to keep the bolts from working loose. A flywheel should always be resurfaced before putting it back, unless it's a new flywheel, in which case you should make sure to remove all of the protective oil.
On the 1994 Yamaha Breeze the valve clearance on the intake should be set at 0.006 inches. The valve clearance on the exhaust should be set at .011 inches.
