Description
General
This section has a description and the repair proce-
dures for several different types of cylinders. The
number and the design of the parts can be different,
but the operation of the cylinders is the same.
Description
This manual covers many different types of cylin-
ders. Each cylinder will be described in detail.
Tilt cylinders are fastened between the frame of the
lift truck and the outer weldment of the mast to
change the angle of the mast and forks.
Two single-stage main lift cylinders and a free-lift
cylinder are used to raise the carriage and extend the
mast weldments.
The two main lift cylinders are installed at the back
of the outer mast. The base of each lift cylinder sits
on a mount at the bottom crossmember of the outer
mast. The top of each main lift cylinder rod fits into a
guide on the top crossmember of the inner mast. The
free-lift cylinder is installed in the inner mast. Each
of the lift cylinders has an internal lowering control
valve. A single external lowering control valve is con-
nected by tubing and hoses to all the lift cylinders.
