*The gearbox oil must be allowed to reach a minimum sump temperature of 60
Degrees C (140 Degrees F) before full torque is applied, to ensure maximum
durability of the gearbox. Highly loaded running of a cold gearbox is not
recommended due to the risk of premature bearing failure caused by the
additional preload applied from cold casings.
The gearbox oil can be preheated by running of the powertrain with the vehicle
on stands, the use of an external oil heater or an oil-to-water cooler connected
to the engine cooling system. Where these systems are unavailable, it is
imperative that the vehicle is driven in a sympathetic manner until the
minimum gearbox oil temperature is reached.
4.3. Gear Cluster
The 1152 gear cluster comprises straight cut, hobbed and/or ground gears mounted
on the easily removable rear cover subassembly, shown in Figure 1 - Section View
of Gear Cluster Assembly. The gearchange operation is a ‘dog’ type.
