Staff took care of issue that was nit created by them. Package was lost by UPS. Propel sent me another part Next Day Air to correct it. -
Excellent experience.

I almost want to cry ;( writing this review because I dont want people to find out about them and rather keep them in my pocket but they deserve it…
This company is great with Quality Products at amazing prices! Sometimes, their website is not the most accurate but is user friendly and if you got questions they will call back and are very prompt in responding via a call or text to verify inventory before placing an order.
I really appreciate and look forward to continuing to work with you all especially Anthony — he is amazing & the best!!!
Frequently Asked Questions
What is the 3T9960 disc used for?
The 3T9960 disc transfers or controls motion through friction or clamping contact within its assembly. A flat, true disc engages smoothly and resists heat and wear.
How do I install the 3T9960 disc?
A reliable installation of the 3T9960 starts with inspection and ends with verification. Follow this process:
- Shut down the machine and follow lockout procedures
- Remove the old disc and inspect the housing and mating faces
- Clean all contact areas and check for warping or glazing
- Install the 3T9960 in the correct orientation and stack order
- Reassemble to specification and confirm smooth engagement
Which Caterpillar machines is the 3T9960 compatible with?

Does the 3T9960 disc meet performance standards?
Yes. The 3T9960 is built to meet OEM specifications for fit, strength, and service life. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications to keep the assembly protected.
How often should the 3T9960 be replaced?
Service life for the 3T9960 depends on operating conditions and load. Replace it on inspection findings or at the interval your manual specifies rather than waiting for a failure.

- Slipping or inconsistent engagement
