    Default '78 CJ Flywheel

    I am swapping stock T150 transmission for T18A. Now I am stuck on getting the flywheel off so I can put the new pilot bushing I got from Novak Adapters (also need to change ring gear). I have not yet tried heating the six bolts up yet, but I can't figure out what to wedge where to lock the flywheel in place. Any other ideas?

    It's been two years since I did my tranny swap & clutch replacement. I did not heat the bolts holding the flywheel. Taking them off (if memory serves me correctly) I used a breaker bar and pursuaded it with a 2 lb dead blow hammer, just enough to loosen it up.
    You'll like the T18 over the T-150, it's a night to day difference in first/low gear.
    Later, T.J.

    I weged a 2x4 between the flywheel gears and the floor, the wood is soft enough that it shouldn't damage the gears. I've done this twice. The first time I used a breaker bar; 1/2 drive and about 2 feet long. The second time I had an air compressor and an impact wrench. The impact wrench is deffinatley the way to go!

    Impact wrench will take it right off. 2x4 also work well to hold like stated above.

    Do not heat these bolts, it will soften them and they will break (I did it).
    Wedge it with a piece of wood or use a impact wrench. You can remove the bushing with out removing the flywheel by packing grease in the hole and using a rod that fits snug in the hole. Drive the rod in and the bushing will slide right out. You might have to repack it with grease a couple of times to get it all the way out.
