Installation notes
The piston pin is fitted between piston and connecting rod. During installation, heat the connecting rod slightly if necessary (according to manufacturer specifications) to allow pin insertion. Always check the bore of the piston and connecting rod for wear before fitting a new pin. Torque specification for bolt retention: 35-41 ft-lb.
Compatibility
Suitable for standard bore pistons. For rebuilt engines with oversize pistons (+0.020", +0.030", +0.040", +0.060"), a matched pin may be required — always verify the specifications of your piston set. The L-134 flathead engine has a standard piston diameter of 3.125" (79.375mm). Pin diameter is approximately 0.8125" (20.6mm) with press fit in the connecting rod.
Historical context
