Complete set of gearbox repair tools
video at bottom
There's everything needed here to completely overhaul a gearbox for a 602 or 435
There are bearing pullers for all bearings and bearing pushers. I have made the pushers because I don't like hitting bearings into aluminium with tube drifts.
Circlip pliers , clamps, guides for inserting the 3 synchro rings and a guide for the bevel gear bearing circlip.
The bevel gear has to be in a designated position and this size is stamped into its face with another reference to when it was made as a matching set with the crown wheel. These items must not be interchanged with different ones. They are made as mates and cannot be separated.
There are different measuring devices, One, to set and check the bevel gear position and adjust it if necessary with a spacer. Another checks the depth of the crown wheel bearings to calculate how many shims of different thickness have to be added in order to achieve the correct meshing of the differential gearing.
There are about 40 tools in the set. It is not for sale, but may be hired or any combination of tools can be put together for you to complete a repair.
I shall prepare a video of the differential set up soon. It's quite clever.
