BREAKING IN PROCEDURES AFTER REPLACING/REPAIRING FINAL DRIVE
Strict conformance with these breaking-in procedures in required for preloading the
tapered roller bearing.
Durning the first 1.000 km (600 miles) the car must be driven at different enging
speeds and road speeds, but never faster than 2/3 of the max. permissible speed in 4th gear
(direct). For cars with a five speed manual transmission (with overdrive) 2/3 of the max.
permissible speed in 4th gear will be applicable to 5th gear.
If there is no conformace with these breaking-in procedures there could be seizure between
the tapered rollers and inner race guide band, which in turn will continuously cause
noise, overheating and oil leakage.
Install tag or label for next oil change in view of driver.
