Frequently Asked Questions

What seal kit fits the Case CX55B boom cylinder?

Broken Tractor carries a boom cylinder bore seal kit made for the Case CX55B mini excavator. It is an OEM-equivalent kit that cross-references part number PS01V00001R300, so you can match it against the number on your old kit or parts listing.

How do I know if the boom cylinder seals are bad on a Case CX55B?

The most common sign is hydraulic fluid leaking at the boom cylinder bore, which happens when the seals become worn or damaged. Leaking seals can also cost the cylinder hydraulic pressure, so a boom that seeps oil or feels weaker than normal is a good reason to inspect the bore seals.

Can I reseal a Case CX55B boom cylinder instead of replacing the whole cylinder?

Yes, a boom cylinder bore seal kit is designed to stop leaks and bring back hydraulic pressure without replacing the full cylinder. Resealing is a practical option when worn or damaged seals are the cause of the leak.

How do I make sure a boom cylinder seal kit will fit my Case CX55B?

Confirm your cylinder bore dimensions before ordering so the seals match your boom cylinder. You can also compare against the OEM cross-reference number PS01V00001R300. If you are unsure, call our parts team at (800) 909-7060 and they can help identify the right kit.
