The Multiquip 30173 Flanged Bronze Bushing is a genuine OEM component designed for Whiteman walk-behind power trowels including the JS60C, JH55C, JH90C, BS90C, BH90C, and BH11C series. As a direct OEM replacement, 30173 is manufactured to the same tolerances and material specifications as the original part, ensuring a drop-in fit with no guesswork on sizing or clearance. Sourced directly through authorized Multiquip distribution channels, this bushing is the correct choice when maintaining your trowel to original equipment standards. Keep part number 30173 on hand as a service spare to avoid unexpected delays during finishing operations.
Key Features
- Sintered Bronze Construction — Flanged bronze provides inherent lubricity and wear resistance, reducing shaft friction at the bushing interface without requiring constant lubrication.
- Flanged Collar for Positive Seating — The integral flange acts as a built-in stop during installation, ensuring consistent axial positioning every time the bushing is pressed or seated into its bore.
- Broad Trowel Family Coverage — Confirmed fit for JS60C, JH55C, JH90C, BS90C, BH90C, and BH11C Whiteman walk-behind trowels — one part number covering both J-series and B-series frames.
- Genuine OEM Dimensional Accuracy — Manufactured to the exact bore diameter and flange thickness of the original specification, preserving correct shaft-to-housing clearance and preventing premature wear on mating components.
- Protects Surrounding Components — A worn or oversized bushing allows shaft movement that accelerates wear on housings, spider assemblies, and adjacent hardware; replacing with the correct OEM part restores tight tolerances throughout the assembly.
A flanged bronze bushing serves as a bearing surface between a rotating or oscillating shaft and its housing, allowing smooth relative movement while absorbing radial load. The flange provides a shoulder that locates the bushing axially within the bore, preventing migration under operating load. When a bushing wears beyond its serviceable limit, shaft play increases, which can cause vibration, uneven blade pitch response, and accelerated damage to the surrounding housing — making timely replacement essential to keeping trowel finish quality consistent.
