ASSEMBLY

1.

Connecting Rod Assembly to Piston Procedures:

a.

Apply clean engine oil to piston pin, piston pin bushings, and connecting rod bushings.

CAUTION

Do not drive piston pin replacer in too far. Replacer may move piston bushing inward

and result in reduced piston pin end clearance.

b.

Insert one new piston pin replacer (Figure 10, Item 16) in position. Then place crowned end of installer

(Figure 10, Item 22) against replacer and strike installer just hard enough to deflect replacer and seat it

evenly in piston (Figure 10, Item 10).

NOTE

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 (0.25 mm)

maximum are allowed.

c.

Place upper end of connecting rod assembly (Figure 10, Item 18) between piston pin bosses and in

line with piston pin holes. Then slide piston pin (Figure 10, Item 17) in place.

d.

Repeat Step 1.b. for second new piston pin replacer (Figure 10, Item 16).
