replacing fibre washer with a brass washer of calculated thickness to give the required end-float.
The latest type differential seals and caps were used (Renault No. 7700-554-257) with the cap
threads sealed with Teflon tape. The drive shafts were attached with standard double roll-pins
locked with safety wire.
The transaxle was mounted using a solid rear mount to prevent any uncontrolled
movement due to suspension loads.
Gear Shift Linkage
A slightly modified gear shift linkage was employed. The rubber mounted reaction bar on
the gearbox was replaced by a solid bar with two spherical bearings. An additional bracket was
mounted on the gearbox casing. The linkage modified in this manner is very-precise and fully
adjustable at the gearbox.
A simple throw-over type reverse lock-out was employed at the gear-shift lever. It was
found most desirable to adjust linkage so that the lever was hard against the lockout in third and
fourth gear. This enabled fast, precise shifts to be made.
