Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the precise 3/8 x 1.59 specification required for correct support block engagement, with no fitting or reworking needed at the pin bore.
- Direct Hardware Replacement — Replaces the original 20279-001 pin on a straight swap, maintaining correct support block alignment and retention geometry.
- Broad Trowel Compatibility — Fits BS46H, JS36H, CS24H, J36-M30, B46, BH-series, JH-series, JS60C, and HDA-Series Multiquip and Whiteman power trowels.
- Structural Integrity Where It Counts — A worn or missing support block pin can allow unwanted movement in the support block assembly, affecting blade pitch consistency and finish quality across the slab.
- Correct Material Grade — OEM pins are produced from specified steel stock to resist shear forces and wear within the support block assembly, extending service intervals between hardware replacements.
The support block pin is a small but load-bearing fastener within the power trowel's pitch adjustment assembly. It secures the support block in position, maintaining the correct geometry that allows the trowel arms and blades to pivot accurately as the operator adjusts blade pitch. When this pin wears, bends, or goes missing, the support block can shift or develop play, leading to inconsistent blade angles, uneven concrete finishing, and accelerated wear on surrounding components. Replacing the 20279-001 promptly restores the mechanical integrity of the pitch assembly and keeps the trowel producing a consistent, quality surface finish.
