precision bearing should require only light taps to

position it. Install the bearing flush with the inside end of

the bore. If the head of a lock pin is damaged, use side

cutters or "Easy-Out" tool to remove pin. Then install a

new lock pin. Apply oil to the thrust washers to hold in

place when the crankshaft is installed. The oil grooves in

the thrust washer bearings must face the crankshaft. Be

sure two notches fit over lock pins.

(4) Reinstall crankshaft in engine block to

perform a check of the crankshaft endplay (fig. 5-26).

Reassemble the crankshaft (199) and associated parts,

piston assemblies (206), connecting rod (197), and

bearing plate (117) with gaskets (120) and (121).

(5) After the rear bearing end plate (117) has

been tightened using the torque recommended in

tabulated data (para. 1-5), check the crankshaft endplay

as shown in figure 5-26. If there is too much endplay
