The Multiquip 11300ZDJ305 is a genuine OEM Crankcase Cover Assembly designed for MTX70HDR and MTX80HDR series rammers. As a direct factory replacement, this cover assembly meets the exact standards Multiquip specifies for the MTX rammer line, ensuring proper crankcase sealing and engine protection on every job. DHS Equipment sources this part directly through authorized channels, so you can order with confidence knowing you're getting the correct component for your machine. Verified compatibility with MTX70HDR and MTX80HDR rammers makes this the straightforward choice when your original cover is damaged, cracked, or due for replacement.
Key Features
- Genuine OEM Crankcase Integrity — Factory-sourced casting and sealing surfaces match the original cover's material tolerances, maintaining the airtight crankcase environment the engine depends on.
- Direct-Fit Replacement — Bolt pattern, port alignment, and mating surfaces correspond exactly to the original housing, allowing straightforward installation without machining or modification.
- Confirmed Rammer Fitment — Compatible with MTX70HDR and MTX80HDR rammers, both GX120 Honda-powered tampers in the Multiquip MTX second-generation lineup.
- Protects Engine Internals — A properly seated crankcase cover prevents oil leaks, contamination ingress, and pressure loss — all of which can cause rapid wear to bearings and lower-end components in a high-vibration rammer application.
- Fuel System Safety Relevance — On diaphragm-carbureted engines like the GX120 HDR configuration, a compromised crankcase cover can disrupt crankcase pressure that the diaphragm carburetor relies on — replacing with a genuine OEM part preserves correct fuel delivery behavior.
The crankcase cover seals the lower engine assembly, enclosing the crankshaft, connecting rod, and lubrication oil within a pressurized environment. On a rammer like the MTX series, where the engine operates under continuous high-frequency impact vibration, this cover is subjected to constant mechanical stress — making material quality and a proper seal critical. A cracked, warped, or poorly sealing cover allows oil to escape and contaminants to enter, which can lead to accelerated internal engine wear and eventual engine failure if left unaddressed.
