For the procedure to install the bearings, refer to the Disassembly and Assembly manual for the machine.

(1) Rubber toric rings, and all contacting surfaces must be clean and dry prior to assembly. Smear a thin film of oil onto the contacting surfaces of the metal seals just before installation. The seal rings must be assembled square with the bore. The rubber toric rings must not be twisted.

(2) Lubricate the contacting surfaces of the seals with the lubricant that is being sealed.

(3) Torque for the 8 bolts ... 150 ± 20 N·m (111 ± 15 lb ft)

(4) Tighten the 20 bolts to a torque of 270 ± 25 N·m (199 ± 18 lb ft).

(5) Tighten the 32 bolts to a torque of 270 ± 10 N·m (199 ± 7 lb ft).
