Had a great experience with ordering correct engine gaskets for our 3208 caterpillar engine
-
Customer service was excellent today! I have never had a company go behind the scenes to see what was happening with my payment error and resolve it so I could complete my order without having to do it all over again. Hats off to Propel Parts!

Great place for Cat parts!
Had some shipping difficulties, but everything was made right. Parts were perfect and an excellent price. Thanks! -
Great pricing and fast shipping!
I'll admit that I was skeptical of propel parts, but they are an honest site and came through with the order. I was skeptical because I've never ordered heavy machinery parts, and didn't know who to trust. The parts that I ordered showed in stock, but after checking with their vendor, they only had half of the order in stock. I was notified the day after the order, and most of the parts arrived in a few days. There was one part that was not shipped putz but I was able to talk with who I assumed is the owner who rectified the situation and had the part overnighted to me.
I will say that communication speed could use a little work, but they will eventually get back with you. -
Good Stuff.
We have had a couple shipping issues, but each time they made it right and we ended up getting what we need. Quality parts at half the price of OEM.
Frequently Asked Questions
What is the 7Y7388 cap screw used for?
The 7Y7388 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 7Y7388 cap screw?
Fitting the 7Y7388 correctly comes down to clean surfaces and following the manual’s sequence. Work through these steps:
- Shut the machine down and isolate power before service
- Verify the thread condition on both the 7Y7388 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 7Y7388 compatible with?
Fitment for the 7Y7388 depends on your specific Caterpillar model and the assembly it serves, so confirm the application before you order. If you are unsure don’t hesitate to reach out to Propel Parts for help verifying fitment.
Does the 7Y7388 cap screw meet performance standards?
Yes. The 7Y7388 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 7Y7388 be replaced?
Plan to replace the 7Y7388 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit. This part is commonly replaced alongside the 1768464 Shim, so it is worth checking both while the assembly is open.
What are the signs of a worn or failing 7Y7388 cap screw?
When the 7Y7388 reaches the end of its service life, the symptoms tend to show up first as performance or wear issues. Look for:
- 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 7Y7388 cap screw important, and what related part is commonly replaced with it?
Replacing the 7Y7388 when needed keeps the system within its designed clearances and loads, which extends the life of the surrounding parts and supports dependable performance. The 1K6870 Lock Nut is commonly serviced together with this part, so it is worth replacing both while access is available.
