I have a L3750 with gear transmission that I'm wondering where the all the bypass valves are.. I know the loader valve is one and there is one behind the hydraulic block [pressure side] on the right side of the transmission,, I took that off and cleaned it and nothing looked warn or broken put a new gasket on and put back on.. I pulled the pump to check the drive gears and both looked good. I installed the original pump with new Orings on the pump housing and all hydro lines.. After putting the pump back on I primed the pump and started it the bucket did curl but slow,, I thought maybe because it had air in the system so I put the FEL lever in the bucket dump position and tried to curl again and it did nothing.. Tried 3 point and it wouldn't work but left the lever in the 3 point up position and quit for the night.. Next morning started it and the 3point raised.. My gut feeling is that it isn't the pump... I don't have a service manual!!!! But from reading online there are posts of other people having the same problem with the L3750.. I have read where there is a bypass at the 3point but you have to take the gas tank, fenders and seat off and you remove the 3point... This tractor had set outside for a while before I bought it. At this time I am draining the hydraulic fluid and have disconnected the FEL quick connects and going tomorrow to get a hydro filter and fluid... I cut the old filter to see if there was any shavings or gunk but was pretty clean... After I get the fluid in I'm going to try it tomorrow without the FEL hydraulics attached and see what happens.. My hope is the 3point will work and my problem will be with the FEL valve.... Thank you for any help or pointers...
Kubota L3750DT with FEL Hydraulic problem
- Thread starter Treejumper
- Start date
I put in new fluid and filter and 3 point raised with my weight [200lbs] on it one time,, wouldn't do it again.. A thing I left out of my 1st post was it has two remote hydraulic connections in the rear above the PTO.. I did push one of the remote levers with nothing hooked up to the quick connects and I could hear the pump labor, not binding.. tried it again and no noise.. The FEL is disconnected..........Do I need a pump???? Any ideasI have a L3750 with gear transmission that I'm wondering where the all the bypass valves are..

Guess I missed your post here, this place is a bit slow at times. Glad ya got it fixed!
I have a L3750, 3 pt works fine, but the loader is slow. I was thinking pump? If you don't mind, can I ask how much your pump cost? And where is it located on the tractor? I haven't really looked into it yet. Thanks!

Close to a 1000....... It is located behind the injector pump,, in fact it is driven by the injector pump.... It is a tandem pump,, hydraulics for loader and 3point [front pump] power steering from the rear pump... That is if you have power steering..It looks like one pump but it is two...Not hard to take off at all,, about 20mins... I got the pump from Tractorsmart.com... They gave me the best price.. # is 717 450 1250 They are in Pennsylvainia.. I don't have a repair manual,, so he helped a lot with his Kubota experience... Ronnie Bowman is his name..
