PISTON & CONNECTING ROD
DESCRIPTION
The pistons are made of a high strength aluminum
alloy. Top land height has been decreased to reduce
emissions. Piston skirts are coated with a solid lubri-
cant for scuff resistance. Connecting rod is forged
steel with a fractured connecting rod cap design. The
connecting rod is also equipped with a squirt hole
and attaches to the piston with a full floating pin
retained by lock rings.
OPERATION
The piston and connecting rod is the link between
the combustion force to the crankshaft.
STANDARD PROCEDURE - FITTING PISTONS
The pistons are machined to two different weight
specifications and matched to rods based on weight.

41TE
-
All piston and rod assemblies weigh the same to
maintain engine balance.
Piston and cylinder wall must be clean and dry.
Piston diameter should be measured 90 degrees to
piston pin at size location shown in (Fig. 96). Cylin-
der bores should be measured halfway down the cyl-
inder bore and transverse to the engine crankshaft
center line (Refer to 9 - ENGINE - SPECIFICA-
TIONS). Pistons and cylinder bores should be
measured at normal room temperature, 70°F
(21°C).
