The Multiquip 43066-2 is a genuine OEM Rexroth Motor Nut M14-1.5 designed for the STXDF series super-sized hydrostatic dual-fuel ride-on power trowels. As a factory-sourced component, this nut meets the exact specifications required to properly secure the Rexroth hydraulic motor on STXDF machines. Sourcing the correct OEM hardware ensures the hydraulic motor assembly remains properly torqued and seated during operation. If you are servicing or rebuilding the drive system on your STXDF trowel, part 43066-2 is the correct factory replacement fastener for the job.
Key Features
- Genuine OEM Specification Fastener — Manufactured to the exact M14-1.5 thread pitch and torque specification required by the Rexroth motor assembly, ensuring proper clamping force without risk of stripping or misfit.
- Direct Hardware Match — Threads directly onto the Rexroth hydraulic motor as originally assembled, requiring no thread chasing, re-tapping, or modification to the motor housing.
- Built for STXDF Ride-On Trowels — Confirmed fitment for the STXDF super-sized hydrostatic dual-fuel series, which uses Rexroth hydraulic motor components throughout the drive system.
- Hydraulic Drive Integrity — A properly secured motor nut prevents micro-movement and loosening under the continuous vibration and hydraulic pressure loads that ride-on trowels generate during finishing operations.
- Critical Fastener for Motor Service — Any hydraulic motor removal, replacement, or drive system inspection on the STXDF requires this nut to correctly reinstall and torque the motor to spec — using the wrong fastener risks motor damage or hydraulic system failure.
The Rexroth Motor Nut M14-1.5 is a precision fastener used to secure the Rexroth hydraulic motor to its mounting point within the hydrostatic drive system of the ride-on trowel. On machines like the STXDF, the hydraulic motor is central to both blade pitch control and machine drive, meaning any looseness or failure at the fastener level can compromise the entire drive assembly. A worn, cross-threaded, or missing motor nut can lead to motor movement, hydraulic leaks, or loss of drive function — making correct hardware replacement essential during any motor service.
