I took my flywheel down to the machinist today, and was going to have it researfaced. I told him that I was using the xt6 clutch kit, but there is .1 of an inch difference in the cup (flywheel surface to pressure plate surface) between the er27 flywheel and the ea82 flywheel. He is concerned if I have it adjusted for the xt6 clutch kit, the clutch disk will rub against the flywheel bolts as it wears down. If I don't have it adjusted, the pressure plate will be overextended and could warp the fingers. OR the clutch will feel grabby because the angles are all wrong due to the pressure plate is sitting lower on the flywheel.

Anyone have some light to this dark puzzle?

 

Thanks,

Ted

With the exception of a clean up of the recessed friction surface (which is the part near the bolts) nothing will get any closer due to the area where the clutch cover bolts on is what gets machined to convert the flywheel to the XT6 spec's. It's been done lots of times, I can't see any problem.

The ER27 flywheel is shallower than the EA82 flywheel - you would be removing material from the PP mounting surface not the disc surface. Thus the flywheel bolts wouldn't be any closer to the disc. Even if they were you could just remove the same amount of material from the flywheel bolt circle.

 

Find a machinist that thinks like a machinist.

Yeah, I got it backwards. :-\ I had a Wile E. Coyote: Genius moment. That's why I came here before I had him do the work. I figured you guys would point me back in the right direction if I was wrong.

I've used an XT6 kit with an un-modified EA82 wheel many times. no problems. even had my loyale apart (swapped from FT4WD to PT4WD before I sold it last fall), and everything looked fine. re-used the ki, it's probably got 30k on it now.

Thanks guys. Flywheel will be ready when I get off work. Project EZWagon here we go.

I have had the XT6 spec (.815?) born on two different flywheels that were both from EA82T's. I was going to do the step reduction and didn't need to. I would check it you may not need to machine yours. Chux, did you check yours?,maybe you got lucky like I did.

I did not check. but I highly doubt it. both of the flywheels in question were from '85-'86 carbed EA82s. And both were on the original clutch when I got them. not likely that they came with the lighter version, and no way were they machined down.

Acording to my machinest, the step on this flywheel was about half way between the two specs. This flywheel came from a 88 SPFI 4WD wagon. Which seems strange since the XT6 is .815 and the EA82 is either .900 or .930 I'm not sure why two specs for the EA82. I got as far as putting the flywheel on the engine, then it rained and it still raining.....
