Yale VC-135EY*T:
Forks will not tilt forward

I am the operator of an extremely old Yale forklift. The forks will tilt back but get stuck moving forward. We have removed and disassembled the shifter valve body and can find nothing apparently wrong with it. We have removed the tilting pistons and used air pressure to assure they aren't stuck. They work with air pressure but won't work on the lift. Up and down also works ok. We have removed the pressure lines and flushed them out. Power steering is a little harder than normal, but since it goes up and down we know we are getting hydraulic pressure from the pump. If a hydraulic line is removed from the tilt pistons they fall forward. Nothing has worked so far to get it to tilt forward without opening a line.

There should be a tilt-lock valve somewhere in the system.

It's either a little block with 4 hoses going in (2 from the tilt valve, 2 from the cylinder side)
(this style is easily and cheaply replaced)

OR, more likely

It will be inside the the spool itself.
It's probably just a broken spring for the poppet valve inside the spool.
