Pistons and Connecting Rod

DESCRIPTION





Fig. 4

The piston is constructed of aluminum and is gravity cast, free floating design. The piston incorporates a centrally located high swirl combustion bowl, and utilizes a "keystone" style top compression ring (Fig. 4), and a rectangular intermediate ring (Fig. 4), for superior cylinder wall scraping. Piston cooling nozzles cool the piston and pin with engine oil supplied by the crankshaft main journals.
The connecting rods are a split angle design constructed of forged steel construction. The rods have a pressed in place wrist pin bushing which is lubricated by the piston cooling nozzle oil spray.
