On another note........ I have heard more than a few times that when changing to the high torque starter, there were issues with getting them shimmed correctly. I have found that that task is better done on a test stand, where you can blue the teeth to check the contact points between the starter and the ring gear. Not a quick fix at all! .02 Good luck.....

There are instructions on shimming with the new starter (or there should be)
basically with the starter pinion engaged with the flywheel gear you should be able to put a pin the thickness of a standard paperclip between the edge of the starter gear tooth and the bottom of the flywheel gear notch (snug fit there is perfect)do not do this with battery cable connected as the starter will power up when you lever the pinion forward

Now I know what you guys are talking about. I didn't know there were 2 piececs to it. How do you go about getting it off if you have removed the flywheel from the engine??
This has been some great info from you guys!! Thanks a bunch!!

)

Re: Can you change a flywheel...
Have you put a dial indicator on the bell housing ? If not,the bell housing to flywheel alignment can cause starter gear misalignment.
Some engine block/bell housing/flywheel combinations require offset locating dowels.The offset dowels replace the straight existing dowels,in the engine block.
If the components mentioned are not centered,the transmission input shaft is out of alignment and probably the starter is also.
After the bell housing is dialed in,the bell housing stater bore location should be verified.
When everything is lined up, a pretty rough set of teeth will mesh.

I left out some info. Its a 1996 Bravo 1 setup on a Gen 6 motor.
Thanks everyone. I have some insight on this repair!

You should do a visual inspection of your ring gear before starting any of your work. Pull the starter and check the teeth for unusual wear or damage. Use mirrors or whetever you can to put eyes on the gear.
