MODEL 149 – 249
CONNECTING ROD BOLTS AND NUTS
When a connecting rod is reassembled in an engine, the original connecting rod bolts and castellated nuts should be replaced with the new Part No. 1212006 bolts with self-locking nuts.
New connecting rods supplied will be shipped with the self-locking nuts in the box. Discard the castellated nuts which are used to hold the rod and cap together.
Tighten the self-locking nuts to 20 to 25 foot pounds with a torque wrench.
