Kubota L35 "scrambled" gears

[ionstegarus]

I have a Kubota L37 (1993 production) with GST.

The clutch died; I bought a new case clutch, plate, o-rings.

I dissasambled the clutch, replace the broken pieces and reasambled.


Also, when i dissassamble the clutch I**

dissambled the GST valve and rotary valve.


*I reasembled all and surprise: the tractor move in front and rear, but it dont have all gear.

And the speed on H are smaller then Low.

It have sometimes only one a gear (the 8 gear) or maximum two gear (the 8 and 4 gears).


What will be wrong? The rotary valve is not syncronized or GSt valve is broken?


Please help me

Sorry, no. But this is exactly what happened to a GST tractor that I know of. The tech revisited the mounting of the part of the rotary valve that was disassembled and corrected the problem without replacing parts.

The rotary valve was put wrong. I rotated the rotary valve and now it's ok.

I need help for this problems:
- for Hi speed when I change the gears (from 1 to 8) it have a delay about 3-4 seconds (a lag) and sometimes does not engage. In order to engage must be pressed the clutch and removed shuttle shift lever from foreward and put again shuttle shift lever to foreward
- for Hi speed when I change the gears (from 8 to 1) it have a delay about 3-4 seconds (a lag) but engage. note must be pressed the clutch and move shuttle shift lever

- for Low speed all gears (from 1 to 8) it working ok.

what can be wrong?
