About Bucket cylinder seal kit

Bucket Cylinder Seal Kits for Excavators and Heavy Equipment

Find aftermarket bucket cylinder seal kits for excavators and other heavy equipment at FAB Heavy Parts. These kits are intended for hydraulic bucket cylinder maintenance and repair. Worn or damaged seals can allow hydraulic fluid to escape, affecting the cylinder's ability to maintain proper sealing. Replacing the appropriate seals can help restore sealing performance when the cylinder's other components remain serviceable.

Bucket Cylinder Seal Kits for Popular Equipment Models

Our collection includes bucket cylinder seal kits for Komatsu, Caterpillar, Hitachi, Kobelco, Hyundai, Case, Doosan, and other equipment brands. Available applications include Komatsu PC200-5, PC200-7, PC220-6, PC220-8, and PC50MR-2; Caterpillar 312, 330, and 345D; Kobelco SK200-6, SK200LC-6, and SK210LC; Hyundai R305-7; and Doosan DH300-5 and Solar 170-3. Product applications vary by kit, so use the individual listing to identify the models covered.

Restore Bucket Cylinder Sealing Performance

The bucket cylinder operates the excavator bucket during digging, loading, and material handling. Hydraulic leaks around a cylinder may indicate damaged or worn seals, although other components can also cause leakage. Inspect the cylinder and related hydraulic components before beginning repairs. A suitable replacement seal kit can help address seal-related leakage, but damaged rods, cylinder surfaces, or other worn parts may require additional service.

How to Choose the Correct Bucket Cylinder Seal Kit

Start with the machine's manufacturer and exact model. Compare the part number shown in the listing with the original part number where available, and check any serial number range or configuration notes. For example, the collection lists Komatsu bucket cylinder seal kit 707-98-25980 for the PC50MR-2 and kit 707-99-59020 for the PC220-8, PC220LC-8, and PC270-8. These are distinct applications and should not be treated as interchangeable.

The collection features aftermarket replacement parts rather than a blanket selection of genuine OEM parts. Review each product's stated condition, part number, and compatible equipment before ordering.

Frequently Asked Questions

How do I find the right bucket cylinder seal kit for my excavator?

Please start with your machine’s make and exact model, then compare the part number on the product page with your existing part number or service documentation, if available. For example, kit 707-98-13990 is listed for Komatsu PC26MR-3, PC27MR-2, and PC27MR-3. If you’re unsure which listing matches your machine, please share the model and part number with us so the application can be reviewed.

Are bucket cylinder seal kits interchangeable with boom or arm cylinder kits?

Not automatically. Bucket, boom, and arm cylinders serve different functions and may use different seal kits. Please select a product specifically listed for the cylinder you’re repairing, and don’t rely on the machine model alone to establish compatibility.

What should I do if my excavator is listed but the part number is different?

Please don’t assume the kits are interchangeable based on the model name alone. Compare the original part number, the product’s stated applications, and any configuration or serial-number details available. If the information still doesn’t match, please send us your machine model and existing part number for review.

Does hydraulic fluid leaking around the bucket cylinder mean I need a new seal kit?

Leaking fluid can indicate worn or damaged seals, but it can also come from damaged cylinder surfaces, other components, or hydraulic connections. Please have the cylinder and related components inspected before deciding which parts are needed. A seal kit addresses seal replacement; it does not by itself repair damage to other components.
