Hello there iam a previous member of the old site and iam wondering if someone could post how to change out a balancer on my bonneville the old site had some pretty good posts of how to do it but i can't seem to find any on this new one. Any help would sure be appreciated.

Thanks, Dan.I

Without air tools, it gets more complicated.

1. Remove RF tire and inner fender liner.
2. Remove belt(s).
3. If you have an impact wrench, remove HB bolt.
3a. If you don't hae an impact wrench, you'll need to remove the plastic flywheel cover (just to the rear of the starter under the bell-housing for the trans) and hold the flywheel in some manner while you use a large breaker bar to remove the HB bolt.
4. Use a HB puller. The bolts in the puller when you buy/rent it most likely will not be right. The 3 small bolts are M6 (I forget the length, I hae several lengths on hand).

Install is reverse.

I think the length on the HB puller bolts is about 70mm and the thread pitch is 1.0 mm/thrd.

I usually hold the flex plate (flywheel) still by slipping a bolt or big round shaft screwdriver through one of the holes and turning the crank bolt CCW until the bolt jams up against the block.

These 2 guys walked me through removing my HB and they know all the tricks. Bill B has another trick up his sleeve if you can't get the crank bolt broke loose.
On the puller bolts, the length will vary, depending on how thick your puller is; thicker ones may need 80-90mm ones. And to find them that long, I had to resort to a fastener distributor. Oh, one last thing... don't be surprised for one of the 3 bolts to not screw in as far. There may be a piece of sheet metal blocking the backside. It will make you think you have it cross threaded or something... so not to be alarmed.

Alright !! Well i think that should get me started anyways i shure appreciate the info i'll let you know how it went and if i left any skin and blood in the process..

Thanks again. Dan .i
