2 General Description
2.1 Connecting Rods
Powder forged and cracked type connecting rods where
introduced into production as a running change during
September 2003. Illustration 6A2-1 shows the difference in
the early cast and machined type (A) and later powder
forged and cracked type (B) connecting rods.
NOTE
Other than the revised manufacturing process
and a revised connecting rod cap bolt torque
specification, all other specifications and
servicing procedures relating to the connecting
rods remain unchanged.
CAUTION
The early type connecting rods can be
replaced by the late type connecting rods.
However, to avoid confusion with having
different bolt torque values, when replacing
early type connecting rods with the late
type, it is recommended that the connecting
rods be replaced as an engine set.
