Frequently Asked Questions

Product

What is the 20Y-70-23220 seal used for?

The 20Y-70-23220 is a sealing component that blocks fluid leakage and keeps dirt and debris out of the assembly. Reliable sealing is key to maintaining pressure and protecting internal parts.

How do I install the 20Y-70-23220 seal?

Fitting the 20Y-70-23220 correctly comes down to clean surfaces and following the manual’s sequence. Work through these steps:

  1. Shut down and depressurize the system, then let it cool if needed
  2. Remove the old seal and clean the bore and shaft surfaces
  3. Inspect the sealing surface for scoring, pitting, or wear
  4. Lightly lubricate the 20Y-70-23220 as directed and fit it square to the bore
  5. Seat it to the correct depth without distorting the lip, then check for leaks

Which Komatsu machines is the 20Y-70-23220 compatible with?

Compatibility for the 20Y-70-23220 seal varies by machine and configuration, so cross-check it for your Komatsu equipment before ordering. If you are unsure don’t hesitate to reach out to Propel Parts for help verifying fitment.

Does the 20Y-70-23220 seal meet performance standards?

Yes. The 20Y-70-23220 is engineered to meet OEM specifications for material, dimensions, and durability. When replacing, choose genuine or high-quality aftermarket parts that meet or exceed OEM specifications so the part performs the way it was designed to.

How often should the 20Y-70-23220 be replaced?

The 20Y-70-23220 is typically renewed during scheduled service or a related repair. In demanding, high-hour operation, inspect it more often to stay ahead of wear. This part is commonly replaced alongside the 02896-21018 Seal O-Ring, so it is worth checking both while the assembly is open.

What are the signs of a worn or failing 20Y-70-23220 seal?

When the 20Y-70-23220 reaches the end of its service life, the symptoms tend to show up first as performance or wear issues. Look for:

  • Visible fluid leaks or seepage at the joint
  • Loss of system pressure
  • Contamination found inside the assembly
  • A hardened, cracked, or torn sealing surface

Why is the 20Y-70-23220 seal important, and what related part is commonly replaced with it?

Replacing the 20Y-70-23220 when needed keeps the system within its designed clearances and loads, which extends the life of the surrounding parts and supports dependable performance. The 07145-00040 Dust Seal is commonly serviced together with this part, so it is worth replacing both while access is available.
