Product Details
| Part Number | 552964 |
| Product Name | Thermo King Washer Spring Lock #10 |
| Function | Locking spring washer for vibration resistance and fastener retention |
| Compatibility | Thermo King refrigeration assemblies and transport refrigeration applications, including Precedent and S-Series applications where spring lock washers are specified |
Material and dimensional specifications follow Thermo King OEM standards for locking washers. Use OEM torque recommendations and fastener combinations when installing to ensure correct clamp load and sealing performance.
Efficiency & Sustainability
Proper fastener retention supports fuel-efficient cooling and precise temperature control by preventing leaks and mechanical shifts that compromise system efficiency. In systems managed by Smart Reefer SR-4 and CARB Evergreen-compliant units, consistent mechanical reliability reduces service calls and component waste, contributing to lower lifecycle environmental impact.
Installation & Maintenance Tips
Install the Washer Spring Lock #10 with the specified OEM fastener pair and torque values. Inspect locking washers during scheduled maintenance intervals and replace any washer showing deformation or corrosion. Use OEM clamps and hardware where indicated to ensure correct fit and long-term reliability.
Real-World Applications
This locking spring washer fits reefer trailers, refrigerated trucks, diesel direct electric units, and stationary refrigeration assemblies where vibration and thermal cycling threaten fastener security. Technicians use it to secure compressor mounts, bracketry, and other load-bearing connections that support stable temperature control across long hauls and stop-heavy routes.
