Shenniu 4/25 with a koyker 150 loader
Hi everyone I’m new to the site and have a question. I’ve bought a tractor with a loader. The tractor is a Shenniu 4/25 with a Koyker 150 front loader. From my research the tractor is from the mid 80’s. When I first got it it worked pretty good. I replaced the seals on 2 of the loader cylinders and it still was working property. We’ll I guess I didn’t tighten something up, but for some reason all the hydraulic fluid leaked out. I ran the pump dry until smoke/steam came out of the reserve tank cap. Long story short is that I need help sizing/finding a replacement pump. The pump was rigged to the flywheel of the tractor and is belt driven. Any help would be appreciated. PS I have very little knowledgeable about things like this. Thanks

PS it appears that the system needs a pump with 5GPM and 2200PSI.

You can try taking the pump to a local hydraulic shop, they may be able to rebuild it.
