Multiquip 11300ZDJ305 Crankcase Cover Assembly - OEM Replacement Part

The crankcase cover assembly protects the internal lubrication system and maintains proper oil circulation in Multiquip tamping rammers. This critical component seals the oil bath lubrication system that keeps the power transmission components properly lubricated during operation. The MT77HFR and MTX-HD series rammers rely on an oil bath system where oil level must be visible through the sight glass—a compromised crankcase cover can lead to oil leaks, contamination, and catastrophic transmission failure.

Crankcase cover damage typically occurs from impact during transport, improper lifting procedures, or prolonged exposure to jobsite debris. Signs of failure include visible oil seepage around the cover perimeter, decreased oil level between checks, or unusual noise from the transmission assembly during ramming operations. The MT77HFR develops powerful compacting force through its centrifugal clutch and transmission system—maintaining a sealed crankcase is essential for optimal performance and equipment longevity.

This crankcase cover assembly is compatible with the following Multiquip rammer models:

• MT77HFR (Honda GXR120RT-KRB6 Engine)
• MTX70HDR
• MTX80HDR
