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. |
