3 -Check ball bearings and roller bearings for smooth areas, pits or other damage.
4 -If the clutch discs are to be used again, keep the clutch packs in the same previous dismantling order separate and record which clutch pack goes with each clutch.
5 -At each disassembly, use a gauge bar to check that total thickness of clutch unit is within the permissible wear limit. If it is not, replace the clutch unit (18) with a new one. Check all clutch plates for burns and inspect the friction material for damage. Inspect the grooves in the friction material for being well traced. Also inspect the clutch drive plates (17) for being perfectly flat, and check them for pits or scratches. If any of the above conditions exists on any of the plates, replace the clutch unit with a new one.
6 -If a new clutch unit is to be used, leave the unit soaked in transmission oil for at least one hour before installing. In any case, before attempting to install the clutch unit, lubricate the contact surfaces of the clutch drive plates with transmission oil. Check the hole on the input shaft entering the rear half housing for any damage that may later cause leaks when clutch is installed. Check the splines on the input shaft for damage caused by steel plates. Replace parts as necessary during installation.
