Frequently Asked Questions
What is the 6Y7935 disc used for?
The 6Y7935 is a friction or drive disc that needs an even surface to engage reliably and handle the heat generated in service.
How do I install the 6Y7935 disc?
A reliable installation of the 6Y7935 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 6Y7935 in the correct orientation and stack order
- Reassemble to specification and confirm smooth engagement
Which Caterpillar machines is the 6Y7935 compatible with?
Fitment for the 6Y7935 depends on your specific Caterpillar model and the assembly it serves, so confirm the application before you order. Or reach out to Propel Parts for help verifying fitment.
Does the 6Y7935 disc meet performance standards?
Yes. The 6Y7935 is manufactured to meet OEM specifications for tolerance and material quality. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications for dependable, long-term performance.
How often should the 6Y7935 be replaced?
Plan to replace the 6Y7935 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit. The 5M7304 Spring Inner is often renewed during the same service, so many technicians replace both at once to reduce downtime.
What are the signs of a worn or failing 6Y7935 disc?
Catching a failing 6Y7935 early prevents wider damage. The common warning signs include:
- Slipping or inconsistent engagement
- Reduced performance under load
- Glazing, scoring, or thinning of the surface
- Unusual noise, heat, or a burning smell
Why is the 6Y7935 disc important, and what related part is commonly replaced with it?
Keeping the 6Y7935 in good condition protects the components around it and supports smooth, reliable operation. Maintaining the assembly with parts that meet OEM specifications helps you avoid unplanned downtime. For a complete repair, the 0328193 Ferrule is another component from the same assembly that is commonly replaced at the same time.
This 6Y7935 Friction Disc is compatible with the following models:
528, 910, 916, 926, 931B, 931C, 931C II, 933, 939, D3C, D3C III, D4C, D4H, D5C, D5C III, D6D, IT18B, IT28B & more...
