The Multiquip 29677 Jackshaft Support Plate is a genuine OEM component designed for Multiquip MP-series masonry saws and HTX/STX-series ride-on trowels. This structural plate provides rigid support to the jackshaft assembly, ensuring correct drivetrain alignment during operation. Verified fitment covers a wide range of equipment including the MP1455HP, MP120E, MP115E, MP1H, HTX6H, HTX6DF, HTXD6i, STX6H, STXD6i, HHNG5, and EHHNK5.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Multiquip's original design tolerances, maintaining the correct load-bearing geometry for the jackshaft assembly.
- Direct-Mount Replacement — Matches original bolt patterns and mounting dimensions for a straightforward swap on supported MP-series saws and HTX/STX-series trowels.
- Broad Equipment Compatibility — Fits MP1455HP, MP120E, MP115E, MP1H, HTX6H, HTXG6DF, HTXD6i, STX6H, STXD6i, HHNG5, and EHHNK5 models.
- Drivetrain Alignment Protection — A correctly installed support plate keeps the jackshaft seated true, preventing premature bearing wear and power loss through the drive system.
- Long-Term Structural Durability — Built from materials consistent with the original specification to withstand the continuous vibration and mechanical stress these machines generate.
The jackshaft support plate is a structural mounting component that holds the jackshaft in its correct position within the drivetrain. By keeping the jackshaft properly located, the plate ensures that power is transferred smoothly and evenly from the engine to the cutting or finishing mechanism. When this plate cracks, deforms, or loosens, the jackshaft can shift out of alignment — leading to accelerated bearing failure, drive belt slippage, and inconsistent machine performance.
