Genuine Koshin Washer ϕ10 — Part No. 0121915
Product Overview
The Genuine Koshin Washer ϕ10 (Part No. 0121915) is an OEM structural fastener component designed specifically for Koshin KTH-80S (3-inch) heavy-duty trash pumps powered by Honda GX270 engines.
Engineered to fit M10 fasteners (ϕ10 nominal inner diameter), this heavy-duty washer is installed alongside the M10 × 50 socket bolts (P/N 0121925 / Pos 11) that anchor the engine drive shaft and flange bracket directly to the pump case. It distributes clamping force evenly, prevents bolt loosening caused by severe pump vibration, and protects the aluminum casing from surface scoring.

Design & Key Features
Vibration-Resistant Clamping: Distributes bolt torque evenly across the mounting surface to prevent M10 engine mounting bolts from backing out under heavy industrial loads.
Casing Surface Protection: Prevents the socket bolt head from gouging or wear-damaging the die-cast aluminum pump case (P/N 0121439) during installation and maintenance.
Guaranteed OEM Compatibility: Precision-sized inner and outer diameters ensure a seamless fit into the KTH-80S engine-to-pump housing counterbores.
Package Includes & Tech Notes
1x Genuine Koshin Washer ϕ10 (0121915)
Maintenance Tip: A full KTH-80S pump assembly requires 4 pcs of this washer (Pos 12) along with 4 pcs of the M10 × 50 Socket Bolts (P/N 0121925). It is recommended to inspect and replace flattened or deformed washers during mechanical seal or engine swaps to maintain optimal clamp torque
