    Stuck Flywheel

    Trying to remove the flywheel from the F134. Tried some light tapping and prying, but no use so far. Will welcome any solution/suggestion. Thank you

    It is probably stuck on the 2 tapered dowl bolts. They are sometimes reamed out and replaced by a precise fitting bolt. In any event spray it down with some penetrate like Kroil. Be sure to soak the bolt shanks where they come through the flywheel. You should be able to tap the outer edges of the flywheel and get it rocking back and forth. Keep us posted. It shouldn't be terribly difficult. Just a little stuck.

    My patience ran out. I ended up drilling out the tapered pieces and tapped off the flywheel. Can I use conventional bolts when reinstalling?

    The Dowl pins hold the flywheel in precise location. You should drill and ream the tapers out and use grade 8 shouldered 9/16 bolts. There is a procedure in the Universal Jeep Service Manual that covers the process pretty well. You want to be sure the bolts fit precisely. If the flywheel can move around even slightly, its a bad thing. Once you drill and ream the bolt holes. you will need to be sure the flywheel is in the correct location. You should indicate it for run-out on the face and the O.D. The Jeep manual steps you through this as well. If the flywheel ends up wobbling in any direction, a lot of things will go wrong.

    Thanks! Read up on the procedure and it looks pretty straightforward.

    Received the dowel pin kit from Vintage Jeeps. This will replace the tapered bolts. A little labor intensive, but necessary. You can access the old jeep service manual:

    I also received the 35/64 bit and 9/16 ( .5625 ) reamer from Amazon. Flywheelkit.jpg, fwbolts.jpg

    A. I pulled the manual and put it in my archive - maybe I can answer somebody's questions from it.

    B. Sometimes we have to bite the bolt (or bullet) and just buy the right tools and parts to do the job right. A six inch rule and a rusty hammer just won't get it done.

    Thanks

    The "obviously Dated" is the most important thing about it! (Just like Larry and I)

    I am going to ask Amy to post this in the Tech Section.

    Read that carefully guys, we're dated, as in old, not "dating".
