My dad bought a shibaura sl1643 4x4 tractor the rocket shafts will not lift. There is a yellow cap and yellow dip stick behind the gear shift. nothing is registering on the dip stick. Is this the resevoir for the PTO and rocket shafts? Does it take tractor hydraulic oil, regular hydraulic oil or gear oil?

Thanks

I have a shibaura sd1643 tractor. The lift started working very very slow and it was making noise. I changed the fluid but didnt help. Now its not working at all and there is no noise. I finally found the filter and pump. The filter was really bad. I cleaned it but still nothing.I finally figured out how to bleed it but still nothing. It appears that the pump is working because when I loosened the nut to bleed it fluid shot out all over me, lol. Any suggestions as to where to go with this now?
Thanks for responding!! ....

Catyup,

You mentioned that you found a very dirty filter, but you didn't mention anything about a sump screen. Have you checked that?

The filter is located in the return line. Fluid is picked up through a sump screen, then pressurized by the pump. The fluid then returns to the sump through the filter you found.

I believe you need to find that sump screen and take a look at it. Most sump screens are designed for cleaning and re-use.

Running that pump without fluid isn't good for it all. A plugged sump screen can quickly destroy any hydraulic pump.

Joel ....

The filter is on the suction side of the pump. There is no screen in the transmission, No filter on the pressure side on any Japanese tractors that I have seen. Your pump may be pumping oil, but not have enough pressure. Raise the 3 point manually, close the lift lock under the seat & see if the lift will go down when weight is put on it. ....
