I have just brought home this backhoe and i have hydraulic pump problems. The pump is mounted on the front of the tractor and it keeps shearing off the drive shaft bolts! I even put in hardened bolts ,went to digging, and after about 10 minutes the bolts broke off! The pump doesn't lock up and the machine works fine until the bolts break. Is it possible that there is a pressure relief value stuck so the pressure builds until the bolts break?Man, thats alot of of pressure to break off 4 hardened bolts!! The pump is not the one that is suppose to be there. It is a rather large pump for the size of the tractor. The hydraulic oil seems to get hot awful fast,a clue maybe?If someone could tell me what pump is suppose to be on that machine, maybe that would be a better option,to just replace it. I just got the machine so I haven't got the manuals yet. I am at my wits end on this one, so any help would be greatly appreciated!!!

If the coupling is misaligned the bolts will be under far more than normal stress. Loosen the pump from the mounts, then put the coupling together. and move the pump untill it seems centered (concentric) with the shaft. If it needs shims. or is pulled crooked by the mount holes, repair the mount, or use shims to get things aligned. Then try it. If the engine is severely loaded by the pump when operating, it is possible that the valving is wrong, or mis adjusted causing it to be closed centered when it is not designed to be, nor intended.

The pump is shaft drive. No excessive vibration and it is mounted solid.It is mounted on the front of machine, off the crank.I'm wondering if this pump is maybe a Low rpm/high volume pump thats not suited to this machine?

Is the hydraulic pump belt drive or shaft?
Is there any excessive vibration on the pump?
Is the pump mounted solid?
