Help!!! Porsche 915/73 Main Shaft Rear Bearing Race Removal

[Gordo2]

Ugh!

I'm trying to remove the main shaft bearing race that fits into the differential housing on the 915/73 transmission (the smaller main shaft bearing - http://www.pelicanparts.com/More_Info/93030239101.htm?pn=930-302-391-01-M260). I'm replacing the bearing, and it comes with a new race - which I understand should be used / installed with the new bearing...

The bearing's outer race is pressed into the differential case, and is kept in place by a small circlip (that doesn't have any means to grasp) on the differential side of the race (keeps the race from moving toward the differential):




For the life of me - I can't remove this circlip - I've been fighting with it for the past hour and a half, with small picks and stuff - but can't get it out.

I can't see how I can press the bearing race out without removing this circlip and I'm getting beat trying to remove it.

Appreciate any thoughts on what I can do.

Thanks,

look up Peter Zimmerman and google up his How-To: Porsche 915 Transmission Repair Tutorial must read if you are in this deep good luck and call Peter

with a small screwdriver get behind the clip in the open slot get it started out of the slot and work it out around the groove

Went to Harbor Freight and picked up some larger picks.

I ground the pointed tip to an angle on the large 90° pick - which allowed me to get under the lip of the clip and use the 90° angle of the pick to leverage / pry against the case.



Gotta have the right tools, and in spite of this one being a cheap throw away - it did the trick...

FWIW I took a different approach (after struggling similarly). I couldn't remove the snap ring but i could rotate it in its slot. Therefore i tapped on the bearing through the gap in the ring, then i would rotate the ring 90 or 180 degrees and tap again. Repeat, repeat... I used a relatively short round headed (hex driven) bolt as my "punch" because it didn't have any sharp edge to scratch anything. It worked nicely.

Nice work - I didn't consider that approach (I was obsessed with getting that clip out).

Good luck, Gordo

Heat the case and they almost fall out.
