D6C 10K13388 # .... running the dozer for a few hours pushing hard , the dozer blade will not lift under load, take the load off will raise just fine , check fluid level was good, new filter.... tilt works fine good down pressure good.....just needing where to start looking ??
does the blade stay up when raised up or does it leak down
the blade stays up
need to put a gauge on it but you have to tie blade down if you bottom out cylinders you wont get a accurate reading because of bipass valves in cylinder
