Frequently Asked Questions

Product

What is the function of the 8T4223 hard washer?

The 8T4223 hard washer is a flat hardware component used to distribute load, prevent surface damage, and ensure proper tightening of fasteners such as bolts and nuts on Caterpillar equipment. It helps maintain clamping force and reduces wear on assembly surfaces.

How do I install the 8T4223 hard washer?

Here’s a general guide for proper installation:

Turn off the machine and make sure it is safely supported before working on any assembly.
Place the 8T4223 washer between the bolt head (or nut) and the mating surface where the fastener will sit.
Insert the bolt through the washer and into the threaded hole or through-hole.
Tighten the bolt or nut to the recommended torque specification from your equipment’s service manual.
Make sure the washer remains flat and fully seated under the fastener during tightening.

Which machines or systems use the 8T4223 hard washer?

The 8T4223 washer is used across a wide range of Caterpillar machines where this part number is specified in the parts list. It may be found in structural, engine, undercarriage, or attachment assemblies where reliable load distribution and secure fastening are required. Always verify fitment using your machine’s service/manual parts list before ordering. If you are still unsure, reach out to Propel Parts, our team will be happy to help you verify if this part fits your equipment.

Does the 8T4223 hard washer meet performance expectations?

Yes, the 8T4223 hard washer is manufactured to meet or exceed OEM quality standards for hardness, dimensional accuracy, and material strength. It’s designed to withstand heavy mechanical loads and environmental conditions commonly encountered in construction and earthmoving operations.

How often should a washer like the 8T4223 be inspected or replaced?

Washers should be inspected whenever you perform maintenance on bolted assemblies or during routine inspections. Look for signs such as deformation, cracking, corrosion, or wear. Replace the washer if it shows any damage or if the fastener becomes loose despite correct torque.

What are common signs that the 8T4223 hard washer needs replacement?

Typical indicators include:

Bent, cracked, or deformed washer surface
Corrosion or pitting on the washer
Loose or shifting fasteners
Uneven clamping or bolt torque loss

Why is using a quality hard washer like the 8T4223 important for equipment performance?

A quality hard washer ensures proper load distribution, protects assembly surfaces, and helps maintain tightness of bolts and nuts in high-stress applications. Using parts that meet or exceed OEM specifications improves assembly reliability, reduces the risk of fastener failure, and contributes to safer, longer-lasting equipment performance.
