No back tilt when hot

I have a Raymond 425-c40tt that has no back tilt once the hydraulic fluid heats up. All other hydraulic functions work fine. It's already had the tilt, priority bypass, and Aux select valves and solenoids swapped with known working parts, as well as CB1 and 2 swapped. There is no leakage past the seals or packing in the cylinders. Any insight would be massively appreciated. Thanks in advance

Did you all find out the problem. I'm having the same situation. I have also tried what you all recommended and the situation still the same. Is there anything that I'm missing.

Looks like it's Solenoid #5, aux prop/relieve valve

Just do it
Hi I have the same problem, and only when it's hot too, i swapped the same valves as the other guy. Mine is a 4150 ac truck and there is only 1 lift/ aux pump not double
No piggy back pumps like the old trucks
The pressure is just fine

Pump is double with aux piggy backed onto main. They fail and cant produce enough pressure. You need a new pump

Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
