Komatsu wheel loader seal kits

Browse aftermarket replacement hydraulic seal kits for Komatsu wheel loaders, including lift, tilt/bucket, steering and other hydraulic-cylinder applications. Fujis Seal organizes this collection to help identify kits by Komatsu WA-series or other loader model, OEM/reference part number, cylinder position, serial range and available rod/bore dimensions.

How to Identify the Correct Komatsu Wheel Loader Seal Kit

• Machine model: confirm the complete Komatsu loader model.
• Serial number: useful when multiple cylinder revisions exist.
• Cylinder position: lift, tilt/bucket, steering or auxiliary hydraulic function.
• OEM/reference number: match the complete Komatsu part or kit reference.
• Rod and bore dimensions: use as a secondary fitment check.

Different cylinder functions on the same loader generally use different seal arrangements, and similar dimensions do not guarantee identical seal profiles.
