I have a TB 135 and was working on a jobsite using the disc mulcher head. Everything was working fine and all of a sudden the hydraulics just quit. The travel pedals locked, nothing hydraulic will move. I just has the main pump rebuilt early summer and even bought a new auxiliary pump. I started troubleshooting by unloosening a hose fitting at the pump and no burst of fluid shooting by....tank is full of hydraulic fluid. What could have occurred? I checked the fuse panel for a blown fuse....no issues there. Help!
I just checked my service manual for troubleshooting and it stated that since I have no functions at all...it is either the pump or the coupling. I am praying that it is the coupling especially since I just had the pump rebuilt several months ago. My next question is, can I remove the pump enough to get the plate off and remove the coupling without having to drain the hydraulic tank and remove the bottom feeder hose?
Safety lever problem,key switch problem? Check the easy repairs first then work to hardest.
I checked the safety levers on both sides; however, if I remember correctly, the blade still works even if the safety levers are up. When I loosened two hoses on top of the pump.....I got no high pressure spray which i think it is either the pump or the coupling gone bad....I hope the coupling since I just had the pump rebuilt a few months ago. I hope that I can remove the two bolts holding the pump and pull it out of the way enough to remove the flywheel cover and be able to remove the coupler.
Blade of not mistaken will still work .Double check the safety switch .I have see the wires break causing the pump to not stroke.Easier them pulling pump off .
In my case, none of the hydraulics are working. It seemed as if I heard a little noise just before I lost hydraulics. I loosened two hoses on the pump while running to see if I would get hydraulic spray but I got nothing. I went to the book and it suggest that either the pump went bad or the coupler. I hope it is the coupler. Gonna go to the site today and see If I can remove it as I don't think the pump is turning at all. I'm just hoping I can get enough clearance to remove the pump without disconnecting the main feeder hose as I hope I don't have to drain all the hydraulic fluid out. Does anyone know if you can disconnect the pump enough to pull the flywheel cover off and then check the coupler?
Well, I found out my problem today and it was worst than I thought. The pump shaft sheared completely off......gotta buy a new pump now.
