Hi. I cannot tilt cab on erf ec6. First I bled the system. By cylinders and by locks. That didn't help. Afterwards I rebuilt the cab tilt pump. Now I have replaced the cab tilt pump. Bled the system by loosening the hoses by both locks. I don't really know if it must be bled by both hoses on each cylinder.
To tilt cab, truck is in neutral. Front is open. Is there any thing else I have forgotten. I have done it exactly as the manual explains.
Hope there is someone who can give me any ideas in how to get it tilted as I need to replace my thermostat. And service the truck.
Thanks for your time.

Are the locks releasing?
1. Cab latch binding. Fails to unlatch.
1. Replace cab latch
cylinder.
2. Pump does not build pressure.
2. Replace pump.
