The Multiquip 45857 Yoke Pivot Pin is a genuine OEM component designed for MD80 and MD105 hydraulic ride-on power trowels. Sourced directly from Multiquip, this pin meets the original engineering specifications for pivot geometry and load tolerances required in the trowel's blade pitch control system. If you're servicing an MD80 or MD105, the 45857 is the correct OEM-specified pin for this application.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact diameter and length tolerances required for consistent pivot articulation in the blade yoke assembly, preventing play or bind during pitch adjustment.
- Direct-Fit Installation — Drops into the existing yoke pivot bore without machining or sizing, restoring the original blade control geometry on reassembly.
- Confirmed Fitment for MD-Series Trowels — Verified OEM fitment for MD80 and MD105 hydraulic ride-on power trowels.
- Blade Pitch Control Restored — A worn or damaged pivot pin causes slop in the yoke linkage, leading to uneven blade pitch and inconsistent finish quality; replacing it with the correct OEM pin restores crisp, responsive blade adjustment.
- Hardened for Repeated Articulation — The yoke pivot sees continuous loading and movement during operation; OEM material specification ensures the pin resists wear and deformation over extended service cycles.
The yoke pivot pin connects the blade pitch yoke to its pivot point within the trowel's hydraulic blade control assembly, allowing the operator to adjust blade angle during finishing. As the pin wears, clearance builds up in the joint, which translates directly to imprecise blade pitch, inconsistent concrete surface finish, and accelerated wear on surrounding linkage components. Replacing the pin at the first sign of looseness in the yoke keeps the blade control system responsive and protects the surrounding hardware from secondary damage.
