Oil Seal Replacement Tool Kit and Service Video for 35 Frame Pumps

Cat Pumps drive-ends have a reputation for being the longest-lasting, most durable pump drive-ends on the market. After decades of use, or through oil contamination of the drive-end, oil can sometimes leak past the seals. Typically, the proper method of replacing crankcase oil seals is complicated and involves removing the two bearing covers, the crankshaft and bearings, and the plunger rod and connecting rod assemblies before finally removing the oil seals. This method is time-consuming but prevents scoring of the plunger rods when using a sharp pick to remove the oil seals.

Cat Pumps engineers have developed a cone-shaped tool to make removing and replacing oil seals on 35 frame drive ends simple and safe. The 32273 tool kit includes the seal removal tool, screws, washers, a Phillips driver and three new oil seals. Check out the new tool in action in the Service Videos section of our 3535 and 3560 pumps. For written instructions on using the tool, review our Service Bulletin 004.
