    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.

Frequently Asked Questions

Product

What is the 0S1012 spring used for?

The 0S1012 spring maintains the correct tension or return force within its assembly, keeping components in proper contact and timing. Consistent spring force is key to smooth operation.

How do I install the 0S1012 spring?

A reliable installation of the 0S1012 starts with inspection and ends with verification. Follow this process:

  1. Shut down and cool the machine, then follow safe procedures
  2. Access the assembly and remove the worn spring
  3. Inspect the bore and mating parts for wear
  4. Fit the 0S1012 with the correct orientation and seating
  5. Reassemble and verify smooth, correct movement

Which Caterpillar machines is the 0S1012 compatible with?

The 0S1012 spring is used across many Caterpillar applications, but the correct fit depends on your exact model and assembly. Always cross-check fitment using your service manual or part reference guide before ordering. If you are unsure don’t hesitate to reach out to Propel Parts for help verifying fitment.

Does the 0S1012 spring meet performance standards?

Yes. The 0S1012 is built to meet OEM specifications for fit, strength, and service life. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications to keep the assembly protected.

How often should the 0S1012 be replaced?

Service life for the 0S1012 depends on operating conditions and load. Replace it on inspection findings or at the interval your manual specifies rather than waiting for a failure. The 1119916 13 9 C13 C15 C18 C4 2 C6 C6 4 C7 C9 Valve Group Solenoid 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 0S1012 spring?

Catching a failing 0S1012 early prevents wider damage. The common warning signs include:

  • Weak return or loss of tension
  • Noise such as ticking or tapping
  • Rough or inconsistent operation
  • A cracked, collapsed, or fatigued spring

Why is the 0S1012 spring important, and what related part is commonly replaced with it?

Keeping the 0S1012 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 8S4501 Lining Shoe Assy is another component from the same assembly that is commonly replaced at the same time.
