The Multiquip 21435 Output Shaft is a genuine OEM component designed for Whiteman and International C and CA Series walk-behind power trowels, including the CA4HC, CA5BC, CA4HM, CA4.4HM, CS24H55E, and CA-4-4H. As an authentic Multiquip OEM part, the part is manufactured to the same specification as the original, ensuring a direct, correct-fit installation with no guesswork. Sourced through DHS Equipment, this Output Shaft is the right call when you need a dependable, like-for-like replacement to get your trowel turning again.
Key Features
- Genuine OEM Construction — Machined to original dimensional tolerances, so the shaft seats, engages, and transmits torque exactly as designed for walk-behind trowel drivetrains.
- Direct-Fit Replacement — Engineered to drop into the OEM mounting position on C and CA Series trowels, matching original spline count, diameter, and length.
- Broad CA and CS Series Compatibility — Confirmed fitment across CA4HC, CA5BC, CA4HM, CA4.4HM, CS24H55E, and CA-4-4H walk-behind power trowel models.
- Sustained Blade-Speed Consistency — A sound Output Shaft delivers smooth, uninterrupted power to the trowel blades; a worn or damaged shaft causes vibration, erratic blade speed, and uneven concrete finishing.
- Backed by Multiquip OEM Sourcing — Carrying the Multiquip part number 21435, this shaft meets the same quality controls applied to new production units, giving you a traceable, warranty-eligible component.
The Output Shaft is the primary rotating component that transfers engine or motor power down through the trowel gearbox to the blade assembly. It links the drive source to the spider and blades, controlling the speed and consistency of the finishing rotation. When the Output Shaft is worn, bent, or damaged, the result is noticeable vibration, a loss of blade control, and a compromised surface finish — issues that worsen quickly under continuous jobsite use and can lead to broader drivetrain damage if the shaft is not replaced promptly.
