Truck cabin hardware: locks and tilt pumps
Cab locks on HGVs secure the cab in the lowered position during normal operation and release to allow the cab to tilt for engine access. A cab lock that sticks, fails to release fully, or does not engage correctly is a safety issue: a cab that is not properly secured in the lowered position represents a risk during normal driving.
DT Spare Parts cab lock assemblies, including the sensor versions that signal cab position to the vehicle's monitoring system, are compatible with the main HGV makes. On vehicles with a cab position sensor, a failed sensor can generate fault codes for the cab security system even when the lock mechanism itself is functional.
Cabin tilt pumps provide the hydraulic pressure for the cab tilting mechanism. A failing tilt pump presents as a cab that tilts slowly, requires multiple pumping cycles, or fails to reach full tilt height. The most common failure mode is internal seal wear. Before replacing the pump, confirm the hydraulic reservoir is at the correct level — low fluid produces identical symptoms to a failing pump.
Cabin hardware fitment is make and chassis-specific. Confirm the correct reference against the vehicle's chassis number before ordering.

Frequently asked questions
What are the symptoms of a failing cab tilt pump on an HGV?
A failing cab tilt pump typically presents as a cab that tilts slowly or requires more pumping strokes than normal. Check the hydraulic reservoir level first — low fluid produces the same symptoms as pump wear.
How do I identify the correct cab lock for my truck?
Cab lock fitment is specific to the make, model, and chassis variant. Use the chassis number (VIN) to identify the correct part reference or provide the chassis number when ordering from Truckstop Group.
Can I replace a cab lock myself?
Cab lock replacement requires safe support of the cab in the tilted position, which typically needs a dedicated cab support stand. Do not work under a tilted cab without appropriate support.
What is the cab position sensor on an HGV?
The cab position sensor monitors whether the cab is fully lowered and locked. It signals to the vehicle's monitoring system and, on some makes, prevents engine start or generates a warning if the cab is not fully secured.
