Product Overview

The 324-0356 Hydraulic Cylinder Seal Kit (also referenced as 3240356 or CA3240356) is an aftermarket hydraulic cylinder reseal package for Caterpillar backhoe loaders and loaders. The official Cat Parts Store lists 324-0356 as a “Hydraulic Cylinder Seal Kit – Standard Size”, i.e. a complete reseal kit for a standard nominal bore hydraulic cylinder. DJF Seals supplies this kit factory-direct to equipment repair shops, parts distributors, and maintenance fleets at wholesale pricing.

Fitment Verification

The Cat Parts Store listing metadata confirms 324-0356 as a Cat hydraulic cylinder seal kit (standard size). FridayParts, Buymachineryparts, PNC Parts, and multiple eBay listings confirm coverage for CAT 416F, 420F, 422F, 428E, 428F, 430F, 432E, 432F, 442E, and 938K lift cylinders.

Verification notes: (1) The previous product text on this page described a “control valve seal kit for excavator main control valves”. That description conflicts with the official Cat listing (hydraulic cylinder seal kit) and with all aftermarket sources, so it has been removed from the product facts. (2) One catalog (Aztec Hydraulics) references 324-0356 as a “bucket cylinder” seal kit, while all other sources identify the loader lift cylinder; please verify the cylinder position against your machine before ordering.

Rod and bore dimensions for this kit are not published in the sources reviewed; contact [email protected] or [email protected] with your cylinder details to confirm suitability.
