Multiquip 366345990 Spring Cylinder MTX 70 - OEM Replacement Part

The spring cylinder is a critical drive component in Multiquip tamping rammers that converts circular motion into the powerful impact force needed for soil compaction. This precision-engineered spring assembly transmits engine power through the centrifugal clutch system to create consecutive compacting impacts at the rammer foot.

Spring failure is a recognized failure mode in rammer troubleshooting procedures. If your rammer jumps erratically, fails to maintain consistent impact force, or shows irregular operating behavior even with proper throttle lever position and correct engine RPM, the spring cylinder may need replacement. Regular inspection of the spring assembly during maintenance intervals helps prevent unexpected downtime on compaction jobs including road work, embankments, pipeline backfilling, and cable installation applications.

This spring cylinder is engineered for Multiquip MTX series rammers that use an oil bath lubrication system. Compatible with the following models:

• MT77HFR
• MTX-70
• MTX-80
• MTX70HD, MTX70HDR, MTX70HF, MTX70SD
• MTX80HDR, MTX80SD, MTX80SF
