Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, ensuring the cover seats and seals exactly as intended for the engine application.
• Direct Drop-In Replacement — Matches the original mounting pattern and profile for the engines used across the RX1575, WM70S/P, CA4HM, QP3TH, MC94P/S, and the broader J36-M30 series, among others.
• Broad Cross-Equipment Compatibility — A single verified part number covering walk-behind trowels, ride-on roller screeds, rollers, concrete mixers, and trash pump models within the Multiquip and Whiteman product families.
• Crankcase Integrity Protection — A correctly seated cover maintains proper oil containment and internal pressure, preventing oil loss and contamination that can lead to accelerated engine wear.
• Verified Part Number Traceability — Ordering by Multiquip part number 1140 confirms you are sourcing the correct assembly, eliminating the risk of receiving an incompatible cover from a different engine variant.

The crankcase cover encloses and protects the crankcase cavity of the engine, maintaining the oil-tight seal necessary for proper lubrication of internal moving components. It acts as a structural boundary that keeps engine oil contained while preventing dirt, debris, and moisture from entering the crankcase. When the cover becomes cracked, warped, or loses its sealing integrity, oil leaks and contamination can follow, placing the engine at risk of increased wear or failure during operation.
