FAQ

Q1: How do I confirm this 17x28x7mm oil seal fits my excavator engine?

A: Measure your existing seal’s inner diameter (ID), outer diameter (OD), and thickness. Our seal matches exactly 17mm ID, 28mm OD, and 7mm thickness. Also, check your engine’s service manual for the recommended seal part number. If your current seal has markings like “17x28x7” or “17*28*7”, it is compatible.

Q2: What is the recommended installation procedure for this oil seal?

A: Ensure the shaft and housing bore are clean and free of burrs. Lubricate the seal lip with clean engine oil before installation. Use a seal driver tool to press the seal evenly into the bore, avoiding damage to the rubber lip. Do not use excessive force or hammer directly on the seal. For best results, consult a professional mechanic if unsure.

Q3: How long does this NBR oil seal typically last under normal operating conditions?

A: With proper installation and regular maintenance, this NBR oil seal can last between 1,000 to 3,000 hours of operation, depending on engine load, temperature, and oil quality. Regular inspection for leaks and shaft wear is recommended to maximize lifespan. Our 6-month warranty covers premature failures due to material defects.
