Key Features
- Genuine OEM Gear Geometry — Manufactured to exact tooth profile and pitch specifications, ensuring smooth mesh and proper power transfer within the rammer drive train.
- Direct Drop-In Installation — Matches the original mounting dimensions and shaft interface of the MT-86D and MT-86D2, so there is no guesswork or modification during reassembly.
- Confirmed Fitment — Verified for MT-86D and MT-86D2 Multiquip rammers, so you can order with confidence that this is the correct part for your machine.
- Restored Drive Efficiency — A worn or damaged pinion causes erratic ramming stroke, excessive vibration, and accelerated wear on mating gears; replacing it with the OEM part restores full, consistent impact energy.
- Durable Material Grade — Produced from the same hardened gear material used in original assembly, supporting the high cyclic loads and impact forces characteristic of rammer operation.
The pinion is a small but critical gear within the rammer's eccentric drive mechanism, responsible for transmitting rotational force from the engine to the components that generate the machine's up-and-down ramming stroke. It meshes directly with mating gears in the drive train, and any wear, chipping, or breakage in its teeth disrupts the timing and force of each impact cycle. A failed pinion will cause the rammer to lose striking power, produce unusual noise, or stop cycling altogether, making timely replacement essential to keeping the machine performing at full compaction capacity.
