The Multiquip 21477 Yoke W/A CA4 is a genuine OEM component designed for CA and JS series walk-behind power trowels, including CA4HC, CA4HM, CA4.4HM, CA5BC, JS36, JS30H55DE, CS24H55E, and CA-4-4H models. As a genuine OEM part, the part is manufactured to the exact specifications of the original assembly, ensuring a correct, direct installation without guesswork. DHS Equipment stocks this part to keep your walk-behind trowel running at full capacity with no compromises on fit or function.
Key Features
- Genuine OEM Construction — Manufactured to original assembly tolerances, so the yoke maintains proper angular alignment and load transfer within the blade pitch mechanism.
- Direct Installation Fit — Matches the original mounting geometry of CA and JS series trowel assemblies, slotting into place without rework or adaptation.
- Broad Walk-Behind Trowel Compatibility — Confirmed fitment across CA4HC, CA4HM, CA4.4HM, CA5BC, JS36, JS30H55DE, CS24H55E, and CA-4-4H models.
- Blade Pitch Control Integrity — A correctly functioning yoke assembly maintains consistent blade angle across the full pitch range, directly affecting finish quality on slab work.
- OEM Part Number Traceability — Ordered by part number 21477, eliminating the risk of receiving a mismatched component when sourcing replacements.
The yoke assembly on a walk-behind power trowel is a critical linkage component within the blade pitch control system. It connects the pitch adjustment mechanism to the spider arm assembly, translating operator input into consistent blade angle changes across all trowel arms. When a yoke wears, bends, or fails, blade pitch becomes uneven or unresponsive, resulting in poor surface finish, increased operator effort, and potential damage to the pitch control linkage. Replacing a worn yoke assembly promptly restores full pitch control and protects the surrounding drivetrain components from secondary wear.
