The Wacker Neuson Cotter Pin is a genuine OEM component designed for the HDR 115 Direct Fired Radiant Heater and the HI35 indirect air heater. As a factory-original part, it is manufactured to the exact specifications required by these Wacker Neuson heating units, ensuring a correct installation every time. This cotter pin is the right choice when servicing or reassembling fastened joints and pivot points on your heater equipment.
Key Features
- Genuine OEM Material Grade — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the correct shear resistance and retention force for this application.
- Drop-In Installation — Matches the original pin bore diameter exactly, seating and spreading without modification for a secure, tool-correct fit.
- Confirmed Fitment — Verified for the HDR 115 Direct Fired Radiant Heater and HI35 indirect air heater series.
- Retains Critical Fasteners Under Load — Keeps pins, clevis bolts, and pivot shafts locked in place during heater operation, preventing unintended disassembly caused by vibration or thermal cycling.
- Fuel System and Mechanical Safety Relevance — On combustion heaters, a missing or failed cotter pin at a fuel valve or control linkage can allow components to shift unexpectedly; using the correct OEM replacement maintains proper mechanical retention.
A cotter pin is a small split fastener inserted through a hole in a bolt, shaft, or clevis pin and then spread open to lock the assembly in position. On combustion heating equipment like the HDR 115 and HI35, cotter pins secure pivot points, linkage connections, and retaining pins against loosening from vibration and heat cycles. When a cotter pin breaks, bends, or goes missing, the fastener it secures can back out, leading to loose linkages, misaligned components, or unsafe operating conditions — making timely replacement with the correct part essential.
