I have a 1995 L4200DTGSTC that I purchased last summer with 1940hrs on it. The tractor had some use, but it started fine ran great did not smoke and pulled great. It had one oil leak at the time (left rear axle) which i pulled it down to the break housing and differential and resealed while replacing the axle seal. Well come winter and the cold and it developed leaks in 5 places.
So two weeks ago I decided to pull the cab and split the little gem, to reseal it. We split it at the bell housing, between the mid case and transmission, transmission and differential. While it was apart I replaced the gasket between the GST Valve Body and outer GST Assembly case and noticed the check valve seats (o-rings) were flattened and getting hard. After we got it all back together it now has a harsh and delayed shift when going into gear (1-8 forward or reverse) before the repair it only had a delayed shift when going between 4th and 5th, but was not harsh.
I do have the workshop manual crazy part is the manual shows the parts but the online parts manual does not show the internal GST valve parts. I am a fairly decent auto/diesel tech just new to Kubota.
I will try and check my pressures tomorrow as per the manual but does anyone know if the parts (Check Valve Seats and the Rotary Valve o-rings) are available?
I'd prefer not to have to replace the GST Valve Assembly @ $1800 if I can just rebuild it.
