Kit di guarnizioni per cilindro benna

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.

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.

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.

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.
