Great service at an affordable price to get my machine back going.
Very thorough ! Confirmed order and great communications.
I put 2 of the same orders in due to a web page error and shortly after I was contacted by Deb from customer service asking if I meant to place both orders. She was very helpful, the email was very well written and it genuinely made me feel better about the whole experience. She resolved the issue quickly and with there not being much of customer service these days I was very happy so see that is not the case everywhere!!!
Excellent service and quick response!
Product Questions
Frequently Asked Questions
What is the function of the 9H6079 oil seal?
The 9H6079 oil seal is a lip‑type oil seal designed to retain lubricating oil inside rotating or moving assemblies and prevent contaminants like dirt and moisture from entering. It’s used in low‑ to medium‑speed applications such as transmissions, pumps, and engines where a tight, durable seal is required.
How do I install the 9H6079 oil seal?
Here’s a general installation guide:
- Park the machine on level ground and shut off the engine.
- Safely relieve any system pressure (oil, hydraulic, etc.).
- Remove the old seal without damaging the housing or shaft.
- Clean the sealing surfaces and bore to remove debris or old lubricant.
- Apply a light coat of compatible oil or grease to the new 9H6079 oil seal.
- Press the seal evenly into its groove or bore using a seal driver or suitable tool until it sits flush and square.
- Reassemble all components and start the machine to verify there are no leaks.
Always follow your machine’s service manual for exact instructions.
Which machines or systems use the 9H6079 oil seal?
The 9H6079 oil seal is compatible with a wide range of Caterpillar machines and engines, including many models listed by Propel Parts such as:
- Wheel loaders like 613C, 910, 924F, 930R, 930T
- Tractors & dozers like D3C II/III, D4C II/III, D4H, D5C series
- Construction & compaction equipment like 769C/D, 771C/D, 773B/D, 775B/D, 54H
- Engines & industrial equipment like 3606, 3608, 3612, 3616, IT12 series
and others where Cat specifies part number 9H6079 for oil sealing.
Does the 9H6079 oil seal meet performance expectations?
Yes. Aftermarket versions of the 9H6079 oil seal are manufactured to meet or exceed OEM specifications for fit, durability, and sealing performance. These seals are designed to provide long‑lasting service in demanding heavy‑equipment environments.
How often should the 9H6079 oil seal be inspected or replaced?
Oil seals should be inspected during routine maintenance or whenever related components (like transmissions, gearboxes, or pumps) are serviced. Look for signs of wear, leakage, or hardening of the seal material. Replace the seal if any signs of deterioration are present to prevent fluid loss and contamination.
What are common signs that the 9H6079 oil seal needs replacement?
Typical indicators include:
- Visible oil leakage around the seal area
- Low oil levels in the reservoir or sump
- Contaminants or dirt around the seal lip
- Hardening or cracking of the seal material
Why is using a quality oil seal like the 9H6079 important for equipment performance?
A quality oil seal ensures consistent lubrication, prevents oil loss, and keeps contaminants out of sensitive components. Using a seal that meets OEM standards reduces downtime, improves machine reliability, and extends the life of gears, bearings, and rotating shafts.
