Oberdorfer 9136CK Keeps Your Gear Pump Running Like New
When a bronze gear pump starts losing pressure, dripping fluid, or running rough, it usually isn't the whole unit that's failed — it's the internal wear parts that have simply reached the end of their service life. The Oberdorfer 9136CK Gear Pump Repair Kit (part number 11305) is built to solve exactly that problem. It gathers the seals, bearings, and gaskets that wear out fastest inside a working gear pump and puts them in one genuine OEM package, so a technician or equipment owner can restore original performance without hunting down individual parts one at a time.
This kit is manufactured to match Oberdorfer's original engineering tolerances, which matters more than it might seem. Aftermarket or mismatched components can throw off shaft alignment, seal compression, or gear mesh, leading to premature failure all over again. Because everything in the 9136CK kit is sized and specified to the original pump design, installation goes smoothly and the rebuilt pump performs the way it did when it left the factory — whether it's moving fuel, oil, coolant, or another compatible fluid.
Gear pumps built on the Oberdorfer platform show up in a wide range of settings beyond boats and marine engines, including industrial fluid transfer systems, agricultural equipment, generators, and various OEM machinery applications. Keeping a repair kit like this on hand, or ordering one at the first sign of wear, is a straightforward way to avoid costly downtime and extend the working life of equipment that depends on consistent, positive-displacement pumping.

Frequently Asked Questions
Q: What does the Oberdorfer 9136CK repair kit include?
A: It includes the core wear components needed to rebuild the 9136 series gear pump, such as seals, gaskets, and bearings matched to OEM specifications.
Q: How do I know if my pump needs this repair kit instead of a full replacement?
A: If the pump is leaking, losing flow, or running noisily but the housing and gears are otherwise sound, a repair kit is typically enough to restore performance without replacing the entire unit.
Q: Is professional installation required for this kit?
A: While an experienced technician is recommended for gear pump rebuilds, anyone comfortable with mechanical disassembly and reassembly can typically complete the repair with basic hand tools.
Q: Will this kit work with pumps outside the 9136 series?
A: No, this kit is specifically matched to the Oberdorfer 9136 series pump design and is not interchangeable with other pump models.
Q: Are the components in this kit made by Oberdorfer or a third party?
A: All components are genuine Oberdorfer OEM parts, manufactured to the same standards as the original pump.
