I have a JICase 300B, it’s a tractor my father purchased new when I was about 9 yrs old. Last fall in early Oct I thought I would tighten up the steering and front end because of some damage to the drag link and tie rods. Seems that the tractor was used as a
bulldozer at some time and the front end couldn’t take the pounding so a fair amount of welding and other barnyard repairs had been done at some time in the long forgotten past.
So I came down with a severe case of project creep and ended up slowly dismantling piece after piece until there were tractor parts all over. Presently the tractor and parts have all been sand blasted and wire brushed to remove 61 years of grease, dirt, rust, and
old paint. Now the parts have all been cleaned, primed, painted and reinstalled.
However, here at the end I have come against a problem I can’t seem to solve so I am turning to you for help. The power steering pump and reservoir combo unit was leaking like a sieve. I removed the pump and then removed the reservoir from the pump to see
what was going on and found that an old O-ring was the faulty part. However, once apart I found on the inside a failed bearing and a scored shaft; something I cannot repair. I was directed to a pump on the Internet that was supposed to work but have come up
against a problem I can’t resolve. I will try to upload photos to help explain the problems.
The pump filler tube is pointing in the wrong direction. The nut on the rear of the pump is slightly off center so I am uncertain if loosening the nut and trying to rotate the pump body will work.
On this tractor the generator is mounted to the top of the pump on the right hand side of the tractor not on the left. If the pump body can be rotated then the generator is in the way of the pump filler spout being turned to the upright position.
If I move the generator to the left side of the tractor there is carburetor linkage that appears to be in the way.
Has anyone else out there confronted these problems and if so what have you done to solve them? Sorry for the novel but it was the only way I could think of to explain my current situation.
Thanks, Carl
