Frequently Asked Questions
What is the 4T2723 washer used for?
The 4T2723 washer spreads a fastener’s clamping load over a wider area, protecting the surface and helping the joint hold torque. It also resists loosening from vibration.
How do I install the 4T2723 washer?
Fitting the 4T2723 correctly comes down to clean surfaces and following the manual’s sequence. Work through these steps:
- Power down the machine and isolate the assembly before service
- Clean the seating surface and check it for damage or burrs
- Place the 4T2723 in the correct orientation under the fastener
- Torque the fastener to specification so the washer seats evenly
Which Caterpillar machines is the 4T2723 compatible with?
The 4T2723 is matched to particular Caterpillar equipment, so always verify the application against your parts reference before purchasing. Check your manual or reach out to Propel Parts for help verifying fitment.
Does the 4T2723 washer meet performance standards?
Yes. Propel Parts supplies the 4T2723 as a premium aftermarket part made to meet OEM specifications. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so you can fit it with confidence.
How often should the 4T2723 be replaced?
Replace the 4T2723 whenever the assembly it serves is overhauled, or any time it shows wear, damage, or corrosion. Following the intervals in your service manual is the best guide. This part is commonly replaced alongside the 1189573 Bolt, so it is worth checking both while the assembly is open.
What are the signs of a worn or failing 4T2723 washer?
When the 4T2723 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
Why is the 4T2723 washer important, and what related part is commonly replaced with it?
Replacing the 4T2723 when needed keeps the system within its designed clearances and loads, which extends the life of the surrounding parts and supports dependable performance. The 1085603 Screw is commonly serviced together with this part, so it is worth replacing both while access is available.
This 4T2723 General Shim is compatible with the following models:
30/30, 35, 416, 416B, 416C, 416D, 420D, 424D, 426, 426B, 426C, 428, 428B, 428C, 428D, 430D, 432D, 436, 436B, 436C, 438B, 438C, 438D, 442D, 446, 446B, 446D, 45, 508, 515, 517, 525, 525B, 525C, 527, 535 & more...
