Just building a TC6.2. Also built an extra TC6.1 Gear Diff.
They appear to be exactly the same however,
The 6.2 does not use any shims on the outdrives (outside diff), but uses two inside (on the deep half) and one inside (on the cover).
They supply 4 shims (two of each).
Anyone know why they are saying to build them differently to the previous TC6 gear diffs.
EDIT:
I just downloaded the latest manual from the website. It differs from the printed manual that came with my Kit.
It says put one large and one smaller shim on the inside of the diff on each side.
They must be trying to reduce the width of the outdrives by a VERY small margin.
Anyone know why?.
Cheers.
The 6.1 build had the small shim outside and the large shim inside. Moving the small shim inside tightens the gear mesh in the diff removing some play between the gears. It is intended to remove slop and make the diff smoother.
