Frequently Asked Questions
How do I confirm JE Pistons 905-042-CT matches my engine parts?
Match every listed dimension and material to the piston, connecting rod, cylinder bore, and intended engine use. A similar bore or diameter alone does not confirm compatibility.
What dimensions must match for this wrist-pin retainer?
Confirm lock type, wire or ring diameter, thickness, piston lock-groove design, and the exact compatible pin and piston. Similar-looking retainers are not interchangeable.
Can wrist-pin locks be reused?
Use new retainers during assembly unless JE expressly approves reuse for that exact retainer design. Inspect the lock groove and install each retainer in the required orientation.
Installation Instructions
Use the current JE Pistons instructions for part number 905-042-CT and the engine builder's measured assembly specifications. A qualified machine shop must verify bore finish, clearances, ring gaps, pin fit, lock installation, orientation, balance, deck height, valve clearance, compression ratio, lubrication, and break-in before operation.
