Hi everyone,
A friend of mine has a 2007 JCB 550-170 telehandler which was working fine when they finished their job and plugged it for the night, the next morning the temperature was like -30 however the machine starts right away but all the hydraulics are dead and nothing is working, no steering, no transmission forward or reverse, no boom or outriggers, even the fan which is run by a hydraulic motor does not work, the owner told me that they checked the hydraulic oil (the boom is still raised a little but all sections are retracted) and they added quite a bit of oil, so when i checked the hydraulic oil the next day there was excessive oil in system but iam not sure that it's the issue, there's two warning lights on the dash the first is a battery light, so iam thinking the alternator needs to be replaced or rebuilt, the owner said it's been on for over a month! the second light is a gear with a drop of oil inside of it, we checked all fuses they were all OK, there's no broken hoses and no visible leaks on the machine and it looks in fairly good condition, so the first thing that comes to mind is the pump, however i haven't done any pressure tests so far as the weather is brutaly cold outside and the machine cannot be transported with the boom raised, any idea if this is electrical or a faulty solenoid somewhere or maybe the hydraulic system is air locked! there's another issue with this machine which is the engine lacking power, even with no transmission and the hydraulics dead the engine is barely picking up RPM with the pedal literally to the metal! also when i riv the engine i can't hear the turbo spool, the machine has a JCB 4.4L Tier 3 SE Engine.
Any ideas or tips would be much appreciated
Thanks.
