5063-5395, AND 5063-5398) (Cont)

g. Assembly

(1) Connecting Rod Assembly to Piston

(a) Apply clean engine oil to piston pin,

piston pin bushings, and connecting

rod bushings.

CAUTION

Do not drive piston pin retainer

in too far. Retainer may move

piston bushing inward and

result in reduced piston pin end

clearance.

(b) Insert one piston pin retainer (16) in

position. Then place crowned end of

installer (22) against retainer and

strike installer just hard enough to

deflect retainer and seat it evenly in

piston (13).

NOT E

Since loading on piston pin is

downward, it must have free

movement to ensure perfect

alignment and uniform wear.

Therefore, piston pin has a full

floating fit in connecting rod

and piston bushings.

Large

clearances of 0.010 inch maxi-

mum are allowed.

(c) Place upper end of connecting rod assembly (18) between piston pin bosses and in line

(d)

(e)

with piston pin holes. Then slide piston pin (17) in place.

Repeat step (b) for second piston pin retainer (16).

Check for piston pin end clearance by cocking connecting rod and shifting pin in bushings.
