Connecting rod bearings are extremely important components of any engine, whether it’s a Toyota or a Ferrari engine. Rod bearings ensure that the rods operate smoothly around the crankshaft on one end, and the piston wrist pins on the other end. Replacing the bearings on a motor is standard procedure for any engine rebuild.
- Remove the connecting rods from the pistons and crankshaft, if they are not already out. The rod’s “big ends” (the larger end) are bolted to the crank with two bolts that hold the end cap on. The “small end” is held onto the wrist pin. The wrist pin is held onto the piston with two circlips. Remove these clips and slide the wrist pin out of the piston and the end of the rod. This should free the rod.
