Most workshops would rather have the right seals on the shelf than order them one at a time. This 2863702X kit puts the seals you reach for during a SHACMAN F3000 or X3000 service into a single box: wheel hub, crankshaft and gearbox rings, all sized to the OEM parts. The kit mixes NBR and FKM. The nitrile rings cover the everyday oil and dust points, while the FKM rings go where the temperature runs high. Each seal sits in its own labelled compartment, so nothing gets mixed
