The Double Order Catastrophe
My co-worker placed an order and wasn't sure it went through online. I later placed the same order thinking the previous order didn't go through. To my surprise both orders went through, and I needed to cancel one of the orders. I called and spoke with someone who instructed me someone would contact me about the situation. I was contacted by Misty and she said she would do her best to cancel one of the orders but not sure if she could because they were next day orders. A small tome later I received an email saying she was able to cancel one of the orders. Thank you to Misty and the entire Propel Parts Team. Greatly appreciated!! -

Frequently Asked Questions
What is the 8Y4387 disc used for?
The 8Y4387 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 8Y4387 disc?
To install the 8Y4387 properly, prepare the area first and confirm the result afterward. Use these steps:
- 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 8Y4387 in the correct orientation and stack order
- Reassemble to specification and confirm smooth engagement
Which Caterpillar machines is the 8Y4387 compatible with?
Compatibility for the 8Y4387 disc varies by machine and configuration, so cross-check it for your Caterpillar equipment before ordering. Please reach out to Propel Parts for help verifying fitment.
Does the 8Y4387 disc meet performance standards?
Yes. The 8Y4387 is engineered to meet OEM specifications for material, dimensions, and durability. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so the part performs the way it was designed to.
How often should the 8Y4387 be replaced?
The 8Y4387 is typically renewed during scheduled service or a related repair. In demanding, high-hour operation, inspect it more often to stay ahead of wear. When servicing this area, the 1219748 Spring Assembly is commonly replaced at the same time.
What are the signs of a worn or failing 8Y4387 disc?
A worn 8Y4387 usually gives early warning through the assembly it supports. Watch for these signs:
- 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 8Y4387 disc important, and what related part is commonly replaced with it?
A sound 8Y4387 is inexpensive insurance against larger repairs. Servicing it on time with parts that meet OEM specifications keeps the whole assembly working as intended. During an overhaul, the 6F8815 Clamp is frequently replaced alongside this part.
