The Multiquip 32112 is a genuine OEM Service Kit 163S8168 Charge Pump 163D70517 designed for Whiteman hydrostatic ride-on power trowels including the HTXD6i, HTX44K4, and STX55J6. As a direct Multiquip OEM part, 32112 delivers the exact components and tolerances specified for the hydraulic charge pump on these machines, ensuring a proper service without the guesswork of adapting non-specific parts. Verified fitment across the HTX and STX series makes this the straightforward choice when it's time to service or restore your charge pump. Keep part number 32112 on hand as part of a proactive maintenance program to stay ahead of hydraulic system wear.
Key Features
- Genuine OEM Service Components — Every item in this kit is sourced directly from Multiquip, ensuring the correct materials, seals, and tolerances specific to the 163S8168 charge pump assembly.
- Complete Charge Pump Service in One Kit — Bundles all necessary service components for the 163D70517 charge pump, so technicians can complete the job without sourcing individual pieces separately.
- Confirmed Fitment for HTX and STX Series Trowels — Engineered for the HTXD6i, HTX44K4, and STX55J6 hydrostatic ride-on power trowels, so you can order with confidence.
- Restores Hydraulic Charge Pressure — A worn or leaking charge pump causes sluggish blade response and loss of drive performance; servicing with the correct kit restores proper hydraulic pressure and consistent machine operation.
- Hydraulic System Integrity — Using OEM-specified seals and components during a charge pump service helps prevent internal leakage that can cascade into broader hydraulic circuit damage.
The charge pump in a hydrostatic ride-on trowel maintains the low-pressure charge circuit that keeps the main hydraulic pump primed and protected during operation. Without adequate charge pressure, the hydrostatic drive system can cavitate, leading to erratic blade pitch control, loss of forward and reverse drive, and accelerated wear on the main pump. Servicing the charge pump with the correct components — as provided in the Multiquip 32112 kit — restores proper circuit pressure and protects the broader hydraulic system from damage caused by oil starvation.
