The Multiquip 120078 Transaxle Backing Plate is a genuine OEM component designed for the Street Pro Series pavement and flat saw lineup, including SP303516, SP303526, SP303520, SP303530, SP605716, SP605720, SP605726, SP605730, SP605736, SP4, and SP6457 models. As a factory-sourced part, the part meets the exact material and dimensional specifications set by Multiquip, ensuring a correct fit within the transaxle assembly. DHS Equipment stocks this part direct from Multiquip, so you can order with confidence knowing you are receiving the right component for your saw.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact material and dimensional tolerances for the transaxle assembly, not a generic approximation.
- Direct-Fit Installation — Matches the original mounting pattern and plate geometry of the transaxle housing, dropping in without rework or shimming.
- Broad SP Series Compatibility — Confirmed fitment across SP303516, SP303526, SP303520, SP303530, SP605716, SP605720, SP605726, SP605730, SP605736, SP4, and SP6457 Street Pro pavement and flat saw models.
- Structural Integrity Under Load — The backing plate anchors the transaxle assembly under the high torque and vibration loads generated during concrete and asphalt cutting, maintaining proper gear alignment throughout the cut.
- Protects Surrounding Drivetrain Components — A correctly seated backing plate prevents axial movement in the transaxle, reducing wear on adjacent gears, bearings, and seals caused by a loose or damaged plate.
The transaxle backing plate serves as a structural anchor within the drive system of MQ Street Pro pavement saws. It secures the transaxle assembly in position, absorbing the rotational and impact forces transmitted through the drivetrain during operation. When the backing plate cracks, deforms, or loosens, the transaxle can shift out of alignment, leading to accelerated gear wear, difficulty maintaining blade speed, and potential drivetrain failure that takes the saw out of service entirely.
