T-250 hydraulic issue I need help with

[cmglawns]

I have a 2006 Bobcat T250 with 4,900 hours. Yesterday it started beeping and flashing the low hydrostatic charge pressure symbol and then the machine dies shortly after. I held the light button and got the code 05-15. I recently had to put a remanufactured left drive motor on it. I put a new drive belt on it but I'm not sure if there's an adjustment to make sure it's tight. I also cleaned the middle case drain filter (it had a decent amount of shavings in it I guess from the old drive motor) and I replaced the hydro filter. None of this fixed it.

Definitely check the hydraulic fluid level. I've seen older machines shut down because of low pressure caused by low level. Its a safety feature to keep you from doing something damaging to the hydraulic system. Since there should be three (3) separate hydraulic pumps on your machine, try to determine if it travels good, along with the bucket functions. If it travels better on the left or right, that is helpful to know. If it does travel fine, then test the bucket functions. I would even load it heavily for a quick test. If everything seems to be working, then the hydraulic sensor is high suspect for being defective. Let us know what you come up with.

Did you completely flush the hydraulic system and replace the cooler when changing the motor? If not depending how much metal was in the system you may have wrecked every thing. Start simple ,check the the drive belt. Those are easy to adjust, crank that adjusting bolt tight.

Dan, are you sure you need to replace the oil cooler? if the oil flow is the same as on an S250, the filter is after the oil cooler? I checked the flow on mine as the cooler was rusty and didn't want any chances of crap getting into bad places.

Coolers in general whether it's a hydraulic cooler or a tranny cooler on a automatic car are huge crap collectors if the system becomes contaminated. Bobcat strongly recommends replacement of the cooler because they don't feel flushing is good enough. Yes it is plumbed cooler then filter so in many cases, the cooler acts as a filter.

A trash collector is a good point, the holes are fairly small and has points that crud can just sit and collect without flowing through the filter.

good afternoon, I have pretty close the same damn problem, after using my T250 for a couple hours, heats up to operating temperature, then it wants to shut off. have to re -start, runs for a bit, same damn thing. over and over. hydraulic light comes on. but no codes show up. any recommendations?
