Specific info required on a sj410 4 speed gearbox please
Posted: Sun Sep 02, 2012 8:13 pm
I've just removed my gearbox and split it down to replace the bearings and oil seals but I've bumped in to something which I hope can be answered by someone more experienced than me.
The two bearings which fit on the main gear wheel shaft have a groove cut in to the outer face in to which fits a half ring - a bit like a circlip without the knobbly bits on the end. The upper and lower casings have corresponding grooves to allow the half ring to lie in the groove. My questions are, should each bearing have two halves so that the grooves are fully encircled?
If one half ring is correct for each bearing, should the half ring be placed so that it sits on top of the bearing, underneath the bearing or half verticle so that it engages with a portion of the top and bottom casings? As I write this I wonder if these half rings are in fact thrust washers, but I still don't know how they should be orientated?
Finally the above detail may be standard for all sj gearboxes but my manuals make no reference to this and I've not split one before.
Thanks
Ian
