The Wacker Neuson Piston Pin is a genuine OEM component designed for the LTN4Y and LTN5Y series light towers, including variant configurations such as the LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN5Yp, LTN5Ypa, LTN5Yp HD, LTN5Ypk, LTN5Y SA, LTN5Y CH, and LTN5Y UK. Sourced directly from Wacker Neuson, this is a factory-genuine part manufactured to the same specification as the original installed component. Fitting the full range of LTN4Y and LTN5Y configurations means you can order with confidence, knowing part number is the correct replacement across this entire model family.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact bore diameter and surface finish tolerances required for correct pin-to-piston and pin-to-connecting-rod fit, preventing play, slap, or premature wear.
- Direct Drop-In Replacement — Matches the original pin length, diameter, and retention groove profile, allowing installation without machining or fitting adjustments.
- Broad LTN4Y and LTN5Y Series Coverage — Confirmed fitment across LTN4Y, LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Yp, LTN5Ypa, LTN5Yp HD, LTN5Ypk, LTN5Y SA, LTN5Y CH, and LTN5Y UK variants.
- Engine Integrity Under Load — A correctly fitted piston pin maintains proper combustion force transfer from the piston to the connecting rod, sustaining consistent power output and compression in the engine.
- Backed by Wacker Neuson OEM Supply Chain — Sourced through the authorized Wacker Neuson parts network, ensuring material grade and heat treatment are consistent with the original production component.
The piston pin — sometimes called a wrist pin — is a hardened cylindrical rod that connects the piston to the small end of the connecting rod inside the engine. It acts as the pivot point through which combustion force is transferred from the piston down into the crankshaft, making it one of the highest-stress components in the engine's reciprocating assembly. A worn or damaged piston pin causes excessive piston rock, audible knocking, accelerated bore wear, and ultimately loss of compression, which will prevent the engine from running reliably or starting at all.
