Multiquip 471354820 Rotary Shaft Drive - OEM Replacement Part for Plate Compactors

The rotary shaft drive is a critical component in the eccentric assembly of Multiquip plate compactors, transmitting rotational force from the engine to create the compaction action that consolidates soil and aggregate. This precision-machined shaft works in conjunction with eccentric rotators and bearings to convert engine power into the high-frequency vibration necessary for effective compaction.

In the MVH-158 series, this drive shaft operates with NJ307MC4 roller bearings and 6907C3 bearings to ensure smooth rotation under heavy loads. The shaft interfaces with the driven gear assembly and piston rod via an 8x50 pin connection, creating the mechanical linkage that drives the eccentric rotators. Common failure symptoms indicating shaft replacement include excessive vibration, unusual noise during operation, decreased compaction efficiency, or visible wear on bearing surfaces.

Compatible with the following Multiquip models:

• MVH158GH

This rotary shaft drive is engineered to OEM specifications for proper fit and performance in demanding compaction applications. Genuine Multiquip OEM part, sold by an authorized dealer.
