Specs At A Glance

Good To Know

Q: How do I confirm this bearing fits my Puma 440? A: Identify which engine your machine carries, whether JLO, Kawasaki, or Sachs, and measure the piston pin and rod bore. That confirms the correct wrist pin bearing before you order.

Q: What else should I inspect during the job? A: Check the piston, rings, and rod bore for wear while the cylinder is removed. Renewing bearing and pin together is standard practice on a top-end rebuild.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
