The Multiquip 0650140470 Spark Plug NGK is a genuine OEM ignition component designed for MT55F and MTR40F series rammers. As a direct OEM replacement, this spark plug meets the original equipment specifications that Multiquip engineers built these machines around, ensuring correct heat range, electrode gap, and thread pitch for your specific application. This plug is confirmed to fit the MT55F tamper and MTR40F trench rammer, making it a straightforward service item for scheduled maintenance or field replacement. Sourced and sold by DHS Equipment as an authorized Multiquip parts supplier, you can order with confidence knowing you are getting the right part for your machine.
Key Features
- Correct Heat Range for Rammer Engines — NGK-spec heat range matched to the high-cycle demands of rammer operation, preventing fouling and pre-ignition.
- Genuine OEM Component — Supplied as original equipment specification, meaning the electrode material, gap, and thread dimensions are exactly what Multiquip specifies for these machines.
- Drop-In Fitment for MT55F and MTR40F — Threads directly into the cylinder head of MT55F and MTR40F rammers with no modification to the plug well or boot.
- Clean Spark for Consistent Ignition — A correctly rated plug fires completely on every compression stroke, supporting smooth throttle response and full power output from the rammer's engine.
- Fuel System Safety Compliance — Using the correct heat-range plug prevents unburned fuel accumulation in the combustion chamber, reducing risk of backfire and engine damage during operation.
A spark plug ignites the air-fuel mixture inside the engine's combustion chamber, and the energy from that combustion is what drives the rammer's reciprocating mechanism and delivers compaction force to the ground. In rammer engines, which run at sustained high cycle rates, heat range and electrode condition are critical — a plug that is too cold will foul quickly with carbon deposits, while one that runs too hot risks pre-ignition damage to the piston. When a spark plug wears or fails, the engine may become hard to start, run rough, lose power, or misfire under load, all of which reduce compaction effectiveness and put extra stress on internal engine components.
