Product Questions
Frequently Asked Questions
What is the 8T4170 cap screw used for?
The 8T4170 is a cap screw used to fasten parts on Caterpillar equipment, delivering the controlled clamp load a secure joint depends on.
How do I install the 8T4170 cap screw?
To install the 8T4170 properly, prepare the area first and confirm the result afterward. Use these steps:
- Shut the machine down and isolate power before service
- Verify the thread condition on both the 8T4170 and its bore
- Clean the mating surfaces so nothing interferes with seating
- Hand-thread the screw first, then bring it to the initial torque
- Apply the final torque in the sequence given in your manual
- Re-check after the first operating cycle if the manual advises
Which Caterpillar machines is the 8T4170 compatible with?
Fitment for the 8T4170 depends on your specific Caterpillar model and the assembly it serves, so confirm the application before you order. Check your manual or reach out to Propel Parts for help verifying fitment.
Does the 8T4170 cap screw meet performance standards?
Yes. The 8T4170 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 8T4170 be replaced?
Plan to replace the 8T4170 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit.
What are the signs of a worn or failing 8T4170 cap screw?
A worn 8T4170 usually gives early warning through the assembly it supports. Watch for these signs:
- A joint that gradually loses torque or works loose
- Damaged, galled, or corroded threads
- Elongation or a thinned, necked shank
- Vibration, movement, or leaks where it clamps
Why is the 8T4170 important, and what related parts work with it?
A sound 8T4170 is inexpensive insurance against larger repairs. Servicing it on time with parts that meet OEM specifications keeps the whole assembly working as intended. Related hardware on our site includes 5V6455 Washer and 5H7225 Nut Inject Valve.
