Key Features
- Exact OEM Dimensions: — Manufactured to the precise 3/8 x 1.59 specification, ensuring the pin seats and retains the support block exactly as intended by the original design.
- Genuine Multiquip OEM Part: — Sourced directly from Multiquip's OEM supply chain, confirming correct material grade and dimensional accuracy for this specific application.
- Broad Trowel Fitment: — Compatible with multiple Multiquip and Whiteman walk-behind and ride-on power trowel families, including BS46H, BH series, JS36H, CS24H, HDA-Series, and J36-M30 models.
- Structural Retention: — Securely locks the support block assembly in place during operation, preventing movement or misalignment that could affect blade pitch control and finishing consistency.
- Direct Drop-In Replacement: — Matches the original pin's diameter and length so installation requires no machining, filing, or adaptation to fit the existing mounting points.
The support block pin is a small but load-bearing fastener that locks the support block into its correct position within the trowel's pitch adjustment assembly. When this pin is properly in place, the operator can make reliable, repeatable blade pitch adjustments — a critical factor in achieving a consistent concrete finish. A worn, bent, or missing support block pin can cause the support block to shift or float during operation, leading to uneven blade pressure, erratic pitch response, and accelerated wear on surrounding components.
