New 2165217 Washer Replacement suitable for Caterpillar Equipment

The 2165217 is a washer that distributes load under a bolt or nut, guarding the mating surface and supporting consistent clamp force.

Fitting the 2165217 correctly comes down to clean surfaces and following the manual’s sequence. Work through these steps:

1. Power down the machine and isolate the assembly before service
2. Clean the seating surface and check it for damage or burrs
3. Place the 2165217 in the correct orientation under the fastener
4. Torque the fastener to specification so the washer seats evenly

Fitment for the 2165217 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.

Yes. The 2165217 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.

Plan to replace the 2165217 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 1189573 Bolt, so it is worth checking both while the assembly is open.

When the 2165217 reaches the end of its service life, the symptoms tend to show up first as performance or wear issues. Look for:

• A joint that won’t hold torque
• Cupping, cracking, or flattening of the washer
• Marking or embedding into the mating surface
• Corrosion that weakens the contact area

Replacing the 2165217 when needed keeps the system within its designed clearances and loads, which extends the life of the surrounding parts and supports dependable performance. The 8T4192 Hex Cap Screw is commonly serviced together with this part, so it is worth replacing both while access is available.
