Kubota L35 changing gears issues

[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

Do you have the WSM (AKA Service Manual)?

Sounds like you have something put together wrong, could be as simple as the Rotary valve put in 180* out (rotate 1/2 a turn).

Give more details on what you took apart.

Thank you for your response,

I don't have the WSM my Kubota, but I found the WSM for other models.

It was correct, the rotary valve was put wrong. I rotated the rotary valve and now it's ok.

but now, i have other 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 foe all gears (from 1 to 8) it working ok.

what can be wrong?

Sounds like a leak, contamination, or damage to the high/low valve.
