Multiquip 352321580 Crank Gear MT-70,85 - OEM Replacement Part

The crank gear is a critical component in the power transmission system of Multiquip tamping rammers, converting the engine's circular motion into the powerful impact force that compacts soil. This OEM gear interfaces directly with the centrifugal clutch system and drives the gearbox assembly that delivers 670 blows per minute at 4,410 lbs. of impact force.

In the MT-85H rammer's oil bath lubrication system, the crank gear operates submerged in 10W-30 motor oil (approximately 1.7 pints capacity), which should be maintained at the halfway point of the sight glass. Gear wear or damage typically presents as unusual vibration, reduced impact frequency, or difficulty engaging the tamping action when the throttle lever is moved from idle to full open position. The MT-85H is designed to operate at 4,000 rpm with the Robin EC12-G 4.0 hp two-stroke engine, and proper gear function is essential to maintain this optimum performance.

This crank gear is compatible with the following Multiquip tamping rammer models:

• MT-85H
• MT-85HS
