ok , i have an old baker 36v b30 te/s. I recently fixed a hydraulic leak. it was the seal between the hydraulic pump for the mast and the motor , this truck has a separate pump for the power steering , well everything is working good , but it wont lift any real weight nor will it lift even an empty pallet past the first stage. i called around and the best info i could come up with for fluid was , and i quote " When in doubt use 10 wt iso32 " im thinking this is the wrong stuff , it will lift a little past the first stage when the oil is cool but after warm up it lifts less and less. the motor doesent seem to labor it just stops lifting. it lifted fine when i got it a few months ago , but after the repair and the new fluid it does this, so if anyone has the info on the correct fluid weight or iso number it would help me a great deal,,thanks in advance. the tilt workes fine with weuight on it also the side shift it just wont go up too well
