JCB Backhoe Loaders seal kits

Shop aftermarket replacement hydraulic seal kits for JCB backhoe loaders, including commonly serviced 3CX and 4CX machines. Fujis Seal organizes this collection for boom, dipper/arm, bucket, stabilizer, steering, extension and other hydraulic-cylinder repairs, with identification by JCB reference number, machine model, serial range and available rod/bore dimensions.

How to Choose a JCB Backhoe Loader Seal Kit

Start with the complete JCB reference shown in the parts manual, cylinder information or original packaging. References in formats such as 991/xxxxx and 448/xxxxx identify specific applications and should be matched exactly.

• Machine model: confirm the full 3CX, 4CX or other model designation.
• Serial number: check when the same model uses different cylinder revisions.
• Cylinder position: boom, dipper/arm, bucket, stabilizer, steering, extension or other function.
• Part number: match every digit, slash and suffix.
• Rod/bore dimensions: use as a secondary check when listed.

Different hydraulic functions on the same machine normally require different seal kits.
