The Multiquip 90551ZE0000 Piston Pin Clip 13mm is a genuine OEM component designed for a wide range of Multiquip equipment, including MTX and MT series rammers, MVC and MVH series plate compactors, MC and CMS concrete mixers, walk-behind power trowels, and diaphragm and centrifugal pumps. As a direct OEM replacement, this clip is manufactured to the exact specification required to secure the piston pin within the engine assembly. Confirming your model number against the fitment list before ordering ensures a correct, hassle-free installation. DHS Equipment stocks this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Retention Specification — Manufactured to exact circlip geometry and spring-steel grade required to hold the 13mm piston pin securely under operating loads and thermal cycling.
- Drop-In Engine Fitment — Installs directly into the piston pin groove without machining or modification, matching the bore and retention depth of the original component.
- Broad Equipment Compatibility — Fits MTX50HD, MTX60HD, MTX60HF, MTX70, MTX70HD, MTX70HDR, MTX70HF, MTX80HDR, MT65H, MT65HA, MTR40HF, MVC40H, MVC64VH, MVC64VHW, MVH-R60H, MVH-R60W, MVB85H, MC-42S, CMS-44S, CA4HM, QP2H, and more.
- Critical Engine Integrity — A correctly seated piston pin clip prevents lateral pin migration during combustion strokes; a missing or failed clip leads to rapid cylinder wall damage and engine failure.
- Safety-Relevant Fastener — In high-cycle compaction and pump engines, piston pin retention is a primary internal safety constraint — using the correct OEM clip ensures the clip seats fully and remains in place under vibration.
A piston pin clip — also known as a circlip or wrist pin retainer — is a small spring-steel ring that locks the piston pin in place inside the piston bore, preventing it from shifting laterally and contacting the cylinder wall. In high-vibration equipment such as rammers and plate compactors, these clips are subjected to repeated shock loads with every compaction stroke, making material grade and dimensional accuracy critical. When a clip fails or is omitted during service, the piston pin can walk out of position, scoring the cylinder wall and causing catastrophic engine damage that typically requires a full engine replacement.
