Key Features
- Genuine OEM Sealing Integrity — Manufactured to the precise 6x11x4 mm dimensional spec required by the GX100 engine, ensuring correct compression and zero-leak performance at the seal interface.
- Direct-Fit Replacement — Matches the original seal profile and housing dimensions for a drop-in installation with no machining or modification to the seal bore.
- Broad Rammer Compatibility — Fits MTX70HF, MTX70HD, MTX70HDR, MTX60HF, MTX60HD, MTX80HDR, MTX50HD, and MTR40HF rammer models from the Multiquip MTX and MTR series.
- Protects Engine Oil Circuit — A correctly seated oil seal prevents crankcase oil from migrating past the shaft, keeping the GX100 engine properly lubricated and clean during high-cycle rammer operation.
- Cross-Referenced to HC-0801043 — Verified against OEM reference HC-0801043, giving you confidence that 91231891003 is the correct seal for your application before ordering.
An oil seal creates a tight barrier around a rotating or reciprocating shaft, preventing engine oil from leaking out of the crankcase while also keeping dirt and debris from entering. On a rammer like the MTX or MTR series, the GX100 engine operates under sustained vibration and repeated percussive loading, which accelerates wear on sealing surfaces. When this seal degrades or fails, oil loss can lead to inadequate lubrication, increased engine wear, and eventually engine seizure — making timely replacement critical to keeping your rammer in full working condition.
