Key Features

• Genuine OEM Sealing Materials — Each gasket and seal in this kit is manufactured to exact OEM material and compression specifications, ensuring proper sealing under the heat and vibration loads typical of power trowel operation.
• Complete Kit Format — Includes all gaskets and seals required for a full service interval in one part number, so technicians have everything on hand without sourcing individual pieces separately.
• Broad Trowel Compatibility — Fits a wide range of Whiteman and International walk-behind power trowel models including CA4HC, CA5BC, J36 series, B46 series, BS90C, JH90C, and many more.
• Prevents Oil and Fluid Loss — Worn or cracked seals allow gear oil and lubricants to escape the gearbox and blade hub, leading to premature bearing wear and costly internal damage — a fresh seal kit stops leaks before they escalate.
• Correct Part for the Job — Sourced directly from Multiquip as part number 21046, eliminating any uncertainty about whether the kit matches your specific trowel configuration.

A gasket and seal kit serves as the primary barrier against fluid leaks within the trowel's gearbox, blade hub, and engine interface points. These components compress against mating surfaces to form a fluid-tight seal, keeping gear oil and lubricants contained where they are needed most. When gaskets harden, crack, or seals begin to weep, lubricant escapes and contaminants enter — accelerating wear on gears and bearings and ultimately causing the trowel to lose smooth blade engagement or suffer internal component failure. Replacing the full set of gaskets and seals during routine maintenance or after a rebuild is the most effective way to restore proper sealing integrity and extend the service life of the machine.
