Case backhoe loader seal kits

Shop aftermarket replacement hydraulic seal kits for Case backhoe loaders. Fujis Seal organizes this collection to help repair shops, equipment owners and parts buyers identify the correct kit by Case machine model, OEM/reference part number, exact cylinder position and available rod/bore dimensions. Applications include boom, dipper/arm, bucket, extension, stabilizer, swing, steering, lift and tilt cylinders.

Case Backhoe Loader Hydraulic Seal Kits

Case backhoe loaders use several hydraulic cylinders on one machine, and each cylinder can require a different sealing arrangement. A boom cylinder kit is not automatically interchangeable with a bucket, stabilizer or steering kit. Models in the 580 and 590 families can also vary by series, serial-number range and installed cylinder.

Depending on the application, a kit may contain rod seals, piston seals, wipers, O-rings, backup rings, wear rings and guide elements. Exact contents and materials vary by product and should be checked on the individual listing.

How to Identify the Correct Case Backhoe Seal Kit

Complete machine model: record the full model and series, not only 580 or 590.
Serial number: important when a model uses different cylinder revisions.
Cylinder position: boom, dipper, bucket, extension, stabilizer, swing, steering, lift or tilt.
OEM/reference number: match every letter, number and suffix from the parts manual, cylinder tag or old packaging.
Rod and bore size: verify the measurement unit; many Case applications use inch dimensions.
Photos and markings: cylinder tags and old seal markings can support cross-reference research when the number is missing.

Part-number matching is the preferred method. Rod and bore dimensions are valuable as a secondary check, but similar dimensions do not guarantee identical seal grooves or profiles.

Common Case Backhoe Loader Cylinder Applications

Rear digging equipment can use boom, dipper/arm and bucket cylinders. Front-loader functions can use lift and tilt/bucket cylinders. Stabilizer, swing, steering and extension cylinders have separate hydraulic functions and may require dedicated kits.

Case Backhoe Loader Seal Kit FAQs

Can I order using only a 580 or 590 model name?

Not reliably. Different series, serial ranges and cylinder positions can require different kits, so use the complete model and part number whenever possible.

Are inch dimensions important?

Yes. Compare the stated rod and bore sizes in the same measurement unit as the cylinder being repaired.

Are these genuine Case parts?

Unless an individual listing expressly states otherwise, products in this collection are aftermarket replacement seal kits supplied by Fujis Seal. Case names and reference numbers are used for compatibility and product identification only.
