A Delay Handled the Right Way
Honestly, if I were in Miami like my shipment was, I wouldn?t have been in a hurry to ship out either. I was frustrated at first ? delays cost me time on the job ? but Propel Parts stepped up.
Deb, Daniel and the team owned the mistake, kept the communication clear, and graciously refunded my shipping costs without making it a hassle. That kind of accountability is rare these days, and I genuinely appreciated how they handled it.
Things don?t always go perfectly, but these folks proved they?re more interested in doing right by their customers than just pushing parts out the door. Solid company, solid people.

P.S. Incredible quality on the pin as well. I had to do some custom modifying, and let?s just say the case hardening was ? well ? hard. Great Stuff! Thank you. -

Frequently Asked Questions
What is the 6I8912 friction disc used for?
The 6I8912 friction disc is a clutch or transmission component used in Caterpillar equipment to transmit torque between rotating elements through controlled friction. For related Caterpillar engine components, visit our engine category.
What are the signs of a worn friction disc?
Replace the disc when you observe:
- Slipping during direction changes or gear shifts
- Burning smell or excessive heat from the affected assembly
- Shuddering during engagement
- Metal flakes in the hydraulic fluid or transmission oil during filter change
- Machine losing torque or power under load
Is the 6I8912 compatible with my machine?
Friction disc compatibility depends on OD, ID, thickness, and spline count. For related hardware, see our heavy equipment hardware parts. Always verify using your machine's service documentation.
How do I install this friction disc correctly?
Before installation, soak the friction disc in the specified transmission or hydraulic oil for at least 30 minutes to pre-saturate the friction material. Stack the disc with the correct alternating arrangement of friction and steel reaction plates as specified in your service manual.
Should I replace friction discs as a set?
Yes ??? always replace the complete disc pack together. Mixing new friction discs with worn steel plates creates uneven engagement and rapid re-wear of the new material.
Is this a quality aftermarket friction disc?
Yes ??? the 6I8912 is a premium aftermarket friction disc manufactured to meet or exceed OEM specifications for friction material composition, dimensional tolerances, and thermal capacity.
