This procedure requires special tools P/N 0048585, pusher tube (f);

P/N 0032028, crank support plate (g); and P/N 0023339 crank support

tube (h).

10.22.1 Slide the support plate between the counterweights at the center of the

crankshaft as far as possible, then place it on the support tube so that

the counterweight on the crankshaft is fully supported.

engine oil.

10.22.3 Using the pusher tube, press the bearing onto the crankshaft until the

bearing rests against the shoulder of the crankshaft.

NOTICE: When pressing, press only on the inner bearing race.

Pressing on any other surface of the bearing may damage the bearing.

NOTICE: Failure to support the crankshaft properly while installing the

bearings may cause the shaft to break.
