3500976 Hydraulic Cylinder Seal Kit for CAT 328DLCR, 329D L, 329E Stick Cylinder – 3412182

This kit is for the stick cylinder on three CAT models: 328DLCR, 329D L, and 329E. Part number 3500976 is the main reference; 3412182 also comes up for the same stick cylinder repair. The stick cylinder works low, close to the tracks, so dust and slurry reach the wiper and rod seal first. When the wiper can’t keep them out, the rod seal wears, and the stick starts to drift or leave an oil film. This kit replaces those sealing points.

Seals are PU and NBR. PU handles the pressure lips and wear. NBR covers oil-side and static sealing. Profiles are made to OEM dimensions, so no trimming or stretching. This is the seal kit only; the barrel, rod, and piston are not part of it.

Before you order, check the machine serial and the cylinder part number. 328DLCR, 329D L, and 329E can have more than one stick cylinder setup, so the model name alone may not be enough.
