16Y-15-00079 is the listed reference for this bulldozer seal ring. Several seal-ring listings in the same range carry similar names and nearby numbers; that does not mean they share a size or application. Use the machine’s serial-based parts catalogue to identify the correct joint and retain the complete part number in the purchase request.
Trace the application before comparing dimensions
Find 16Y-15-00079 in the assembly illustration and note the groove, mating surfaces and installation position. The current listing does not identify the sealed medium, material or dimensions. Ask the supplier for verified specifications if those affect service, and do not infer them from a photograph. If the old ring is flattened or damaged, use its marking and catalogue location rather than its worn shape as the sole guide.
Installation checks
Clean the groove and mating surfaces without leaving debris or causing scratches. Confirm that the replacement sits correctly and is not twisted or pinched during assembly. Use lubricant only where the service instructions specify it, and complete the approved pressure or leak check for the assembly. If the joint failed repeatedly, inspect the groove and adjoining components as part of diagnosis.
Compare the related but distinct 16Y-15-00080 seal-ring reference and the 16Y-15-00017 reference; check each number against the exact diagram position.
