Novel Pump Adapter
Novel part adapts standard hydraulic pumps to proprietary Yanmar tractor application.
My Yanmar pump adapters
Irritated by the high cost of a replacement KYB/Kanzaki hydraulic pumps for my Yanmar compact diesel tractor, I designed an adapter that allows standard flange-mount gear pumps to fit the model 2T90 and other Yanmar diesel engines.
Original KYB/Kanzaki pump
Generic replacement gear pump with new coupling
New pump installed on engine
Because the new pump has a different shaft, I had to make a new coupling.I also chose to retrofit the old coupling in case someone needs my adapter in the future.
New coupling I made for new shaft diameter
Recycled old coupling will now fit new shaft
I do have a few more of the adapters, so Contact me if you are interested in buying one and modifying your coupling.
