Frequently Asked Questions
How do I confirm this wrist pin fits my pistons and rods?
Match the exact outside diameter, length, wall thickness, material, piston pin bore, connecting-rod small end, lock style, and manufacturer part number.
Can a wrist pin be substituted based on diameter alone?
No. Length, wall thickness, material, heat treatment, lock arrangement, weight, and intended cylinder pressure are also critical.
Should pin clearance be measured before assembly?
Yes. A qualified engine builder should measure piston and connecting-rod pin clearance and follow the current CP lubrication, retention, and installation specifications.
Installation Instructions
Professional engine machining and assembly are required. Follow the current CP Pistons and engine-builder instructions for this exact part number. Measure every bore and component, verify all clearances and ring gaps, clean all parts and oil passages, use the specified lubricants and fastener procedures, confirm rotating-assembly and piston-to-valve clearance, and complete the required break-in and calibration.
