I need help trying to remove the bellhousing to swap engines. However I can't seem to get the flywheel off. After removing the clutch, etc., and six bolts holding on flywheel it still want budge. How much pressure does it take to come off motor shaft. I don't want to damage it. | | | | | Joined: Aug 2005 Posts: 157 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2005 Posts: 157 | Probably stuck on the dowels (3, as I recall on the 216 engine). What I did last time I messed with one of these, was loosely bolted the pressure plate on and used it as a "slide hammer" to help pull the flywheel loose from the dowels.
Some stick & some don't. . . . | | | | | Joined: Jun 2005 Posts: 887 Shop Shark | | Shop Shark Joined: Jun 2005 Posts: 887 | I used an air impact wrench to get mine free, and that sucker puts out up to 450 ft/lbs of torque. If you don't have an air impact, try a breaker bar. If you don't have a breaker bar, a piece of pipe over the end of your ratchet handle will give you some leverage and the mechanical advantage you need-- the longer the better!

If I read his message right, he already has the flywheel bolts out. I guess I don't know what I'd put a impact wrench or breaker bar on. I DO know that it's a bad idea to start walloping the bejeesus out of the back of the flywheel. I've also used a rubber (or lead) hammer to gently rock the flywheel back and forth just a little on the dowels. Once you get a little motion, it's as good as off. | | | | | Joined: Jun 2006 Posts: 91 Wrench Fetcher | | Wrench Fetcher Joined: Jun 2006 Posts: 91 | Thanks guys, It sounds like after the bolts are removed that it in theory should come off. I wasn't aware that there are dowel it could be stuck on. I quess I will just need to apply alittle more pressure. I will stop and get me rubber hammer on the way home from work to try that first. | | | | | Joined: Aug 2005 Posts: 157 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2005 Posts: 157 | | | | | | Joined: Apr 2005 Posts: 345 Shop Shark | | Shop Shark Joined: Apr 2005 Posts: 345 | I would think that tapping opposite sides of the flywheel would help. You may need to rotate the engine to do this. | | | | | Joined: Jun 2006 Posts: 91 Wrench Fetcher | | Wrench Fetcher Joined: Jun 2006 Posts: 91 | On the way home a bought a 5 dollar rubber mallet. After whopping the flywheel, several times and rotating, through the starter hole it gave it alittle wiggle room. Then just as mentioned it was unstuck and comming off. I had no idea it was going to be that heavy! .....Thanks bolters | | |
