Assembling Connecting Rod to
Piston
[212 LP & NP]
1. Install a retaining snap ring in one of the
wrist pin retaining grooves.
2. Position the connecting rod in the piston
assembly. Make sure that the side of the rod
marked FRONT is properly aligned with the
FRONT markings on the piston crown and
skirt (Figure 240).
The current piston skirt, part No. 240GC590BM,
is symmetrical in design, having piston cooling
nozzle clearance cutouts on both the right and
left sides. Although the word “FRONT” still
appears at the bottom, the symmetrical design
allows the skirt to be assembled to the piston
crown in either direction.
Be sure that the piston and rod assemblies are
clearly marked with the cylinder location. They
must be returned to same cylinder from which
they were removed.

3. Using a generous amount of clean engine
oil, push the piston wrist pin into the wrist pin
bore, aligning the two piston sections and
the connecting rod.
Current-production piston crowns DO NOT use
bushings in the wrist pin bores.
4. Secure the pin in position by inserting a
snap ring in the remaining piston snap ring
groove.
5. Place the assembled piston in a clean
location until it is needed for installation into
the engine cylinder sleeve.
6. Perform steps 1 through 5 on the remaining
pistons.
