Description
The tilt cylinders provide backward and forward tilt of the
upright. The forward and back tilt angles are governed by
the cylinder stroke and by use of spacers and different
length rod ends. The tilt cylinders are pin-mounted to the
truck frame and upright using yokes, clevises, and pins.
Pins are held in place by a lock plate and fastener to pre-
vent the pins from working their way out.
The tilt cylinders are serviced by removing them from the
truck and disassembling them for complete overhaul,
including installation of new seals and or other cylinder
components.
The tilt lock valve is integrated into the tilt section of the
main hydraulic control valve. The tilt lock valve prevents
the upright from tilting forward when the truck is not run-
ning. The tilt lock valve is not serviceable and must be
replaced as a valve section if defective.
