The Multiquip 303010170 Check Spring MTR55 is a genuine OEM component designed for the MTR55 trench rammer. Sourced directly from Multiquip, this spring is an exact match to the original part installed at the factory, ensuring correct fitment and function without guesswork. If you're servicing an MTR55 and need a dependable, spec-correct replacement, the part is the part to order.
Key Features
- Genuine OEM Spring Tension — Manufactured to the exact load and coil specification of the original, so valve or check action performs as intended on the MTR55.
- Direct Drop-In Replacement — Matches the original mounting position and dimensions on the MTR55, fitting into place without rework or modification to surrounding components.
- Confirmed MTR55 Fitment — Validated for the Multiquip MTR55 trench rammer, eliminating compatibility uncertainty when ordering.
- Sustains Proper Check Action — A correctly functioning check spring maintains controlled, consistent ramming cycles; a fatigued or broken spring can cause erratic operation or loss of compaction force.
- Fuel System Integrity — As part of the carburetor or fuel circuit assembly, a properly rated check spring helps maintain correct fuel flow and prevents flooding or lean-running conditions that accelerate engine wear.
A check spring is a small but critical component in the fuel delivery or valve circuit of a rammer engine. It applies controlled tension to hold a valve or diaphragm in its correct seated position, allowing one-directional flow while preventing backflow or pressure loss. When a check spring loses tension, deforms, or breaks, the engine may run erratically, fail to start, or deliver inconsistent power strokes — directly affecting compaction output and cycle rate on the MTR55.
