DESCRIPTION
The relief valve can be identified as item 11 in Section
230-0000, BODY SYSTEM SCHEMATIC.
Mounted off the kick-over valve at the rear of the
transmission, the relief valve is located in the hydraulic
body circuit between the body cylinders and the kick-
over valve (See Fig. 2).
The relief valve (safety valve) is installed in the
hydraulic lines between the kick-over valve and the
lower ports on the body cylinders. Should pressure in
these lines exceed 207 bar (3 000 lbf/in²) the valve will
open and excess oil will return to the body and disc
brake cooling tank.
