Multiquip 10890 Gearbox Fan Cover W/A R.S.

The Multiquip 10890 Gearbox Fan Cover W/A R.S. is a genuine OEM component designed for JTO-SERIES Whiteman ride-on power trowels. This direct-replacement cover is sourced straight from Multiquip, ensuring it meets the same specifications as the original part installed at the factory. If you're maintaining or rebuilding a JTO-SERIES trowel, using the correct OEM cover means no guesswork on fit or function. DHS Equipment stocks this part to help keep your trowel turning without unnecessary delays.

Key Features

• Genuine OEM Construction — Manufactured by Multiquip to the same material and dimensional standards as the original, ensuring the gearbox fan housing seats and seals correctly.
• Direct Bolt-On Replacement — Designed to drop into the existing mounting points on JTO-SERIES trowels, requiring no modification to surrounding components during installation.
• JTO-SERIES Fitment — Confirmed compatibility with Whiteman JTO-SERIES ride-on power trowels; always verify your model code before ordering.
• Gearbox Protection — A properly fitted fan cover channels airflow correctly and shields internal gearbox components from debris and contamination during operation.
• Correct Part Number Sourcing — Part number 10890 is the Multiquip OEM reference; using the verified part number eliminates the risk of ordering an incompatible substitute.

The gearbox fan cover on a ride-on power trowel serves two critical roles: it directs cooling airflow across the gearbox assembly to prevent heat buildup during extended finishing runs, and it acts as a physical barrier that keeps concrete dust, slurry, and debris from entering the gearbox housing. When this cover is cracked, missing, or improperly seated, the gearbox is exposed to abrasive contamination that accelerates internal wear and can lead to premature gearbox failure. Replacing a damaged cover promptly with the correct OEM part is one of the simplest ways to protect a high-value drivetrain component.
