Steven & Propel Parts were a huge help! We were able to place a large order and get it shipped out same day to avoid a line down situation for a customer due to a lost component. The order was even submitted after the 3pm cutoff for same day shipments and we got it the next morning!

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
What is the 6I1647 mounting component used for?
The 6I1647 mounting component plays a specific role in its assembly on Caterpillar equipment, contributing to safe, dependable performance.
How do I install the 6I1647 mounting component?
A reliable installation of the 6I1647 starts with inspection and ends with verification. Follow this process:
- Shut the machine down and isolate power before working on the assembly
- Clean the mating surfaces and inspect them for wear or damage
- Remove the old part and check the area for debris
- Fit the new 6I1647 in the correct orientation per your service manual
- Reassemble to specification and confirm correct operation before returning to service
Which Caterpillar machines is the 6I1647 compatible with?
Fitment for the 6I1647 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 6I1647 mounting component meet performance standards?
Yes. The 6I1647 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 6I1647 be replaced?
Plan to replace the 6I1647 during a rebuild of the surrounding components, or sooner if inspection shows it is past its serviceable limit. The 7W2518 Bolt Head 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 6I1647 mounting component?
Catching a failing 6I1647 early prevents wider damage. The common warning signs include:
- Visible wear, cracking, or corrosion on inspection
- Reduced performance or reliability in the assembly
- Unusual noise, movement, or leaks near the part
- Premature wear on the components around it
Why is the 6I1647 mounting component important, and what related part is commonly replaced with it?
Keeping the 6I1647 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 8S6045 Shim Liner is another component from the same assembly that is commonly replaced at the same time.
This 6I1647 Arm Gp is compatible with the following models:
3304, 3306, 3306B, G3304, G3304B, G3306, G3306B, GENERATOR, INDUSTRIAL, TRUCK, MARINE & more...
