Key Features & Benefits

This valve basically controls the hydraulic pressure to the cab tilting mechanism. It manages how smoothly and evenly the cab lifts and lowers. It doesn't make the cab tilt, it just regulates how it tilts. It’s got internal components that measure pressure and adjust accordingly, preventing things from going crooked or jerking around. Think of it as the brain controlling the hydraulics when you need to access things under the cab – for engine work, or maybe some electrical repairs. When you’re raising or lowering the cab, this valve makes sure it’s a controlled movement, and that both sides lift at roughly the same rate. It’s a key component in the whole cab tilting system, working with the hydraulic pump, lines, and the tilting rams themselves.

Symptoms, Risks & Replacements

If this valve starts to fail, you’ll notice if the cab doesn’t lift smoothly, or if one side goes up faster than the other. It can even lead to binding – where the cab gets stuck mid – tilt. Ignoring it can lead to damage to the rams, the tilting mechanism itself, or even put stress on the cab mounts. It acts like a shield, protecting the more expensive components. You can usually find a replacement fairly easily – Fixparts Online has a good selection, as do other suppliers. It's a relatively inexpensive part compared to the damage a bad one can cause, so it's worth addressing when it starts acting up.
