RNG00748 Trane Chiller Parts External Retaining Ring .461" Free Dia For CenTraVac Guide Vane Linkage HVAC Refrigeration Spare Parts

RNG00748 is a Trane shaft elastic retaining ring (outer spring washer), belonging to HVAC accessories, compressor accessories, central air conditioning refrigeration accessories, and chiller accessories. It is used for positioning the shaft end of the CenTraVac centrifugal compressor guide vanes and fork mechanism, and is a major overhaul replacement component. The free diameter is 0.461 inches. The short notation RNG748 with a zero added represents this part. This is a retaining ring rather than an O-ring. Do not place an order for this based on the RNG series sealing rings; the installation position and material must be verified against the old part and the unit list. Before installation, clean the shaft groove, remove burrs, install it with a special retaining ring wrench and confirm it is fully inserted into the groove, and do not use brute force to pry; after installation, check for no looseness in the axial direction. The elasticity of the old part has decreased and it cannot be reused.
