Mk3 Gearbox Continued

Bearing removal

Secondary shaft complete with rear bearing as removed

Primary shaft with front and rear bearings as removed, Shoulder piece is detached from in front of the bearing

The two shafts are shown as they were removed above. Getting the bearings off wasn't too hard, I removed the front bearing from the Primary shaft using a two-legged puller, having refitted the clutch nut to protect the threads on the shaft...

I removed the other bearings from both shafts using a bearing separator- its intended for bearings rather larger than this but it did a good job...

Assemble the two halves behind the bearing and tighten up the bolts

Screw in the side bars and fit the puller head,I used the conical tip to engage in the hole at the end of the shaft.
Then tighten the puller and the bearing pulled off neatly

The next step was to remove the bearing which had remained in the gearbox front cover- for this I used a blind bearing puller... first time I had used this bit of kit which has been knocking about for ages. How satisfying is that????

First step was to assemble the collet head in the bearing and
 tighten it down to expand it beneath the bearing

Screw in  the slide hammer

A couple of slide whacks and out popped the bearing

The last step was to remove the two oil seals still stuck in place; one in the front plate and one in the housing. A simple job using a suitably sized socket to punch the oils seal out into a larger socket beneath that is taking the weight.

using two sockets to remove oil seal, note large socket beneath

Seal removed, The seal in the case was removed in the same way.

The bearings in the gearbox case are KLNJ5/8 or 5/8 x 1 3/8 x 9/32 (also known as R10 EE5) and LJ5/8 or 5/8 x 1 9/16 x 7/16 (also known as RLS5 LS7). I ordered 2 of each from a bearing supplier. The oil seals are a little more difficult. The numbers on them specify 11907915, or 1.19 OD, 0.79 ID and 0.15 thick (dimensions in inches). These don't seem to be made any more although some specialist suppliers have them still. The closest modern size is 30, 20, 4 dimensions in mm and these are readily available. They cost about half as much so I ordered a couple to try them- will let you know whether they fit!
