Removal And Replacement Of The Hydraulic Valve - Cub Cadet 3000 Series Service Manual

Removal and Replacement of the Hydraulic Valve

Prior to removing the hydraulic valve, it is necessary
to remove the fender assembly.
CAUTION: Slowly remove the hydraulic lines from the
hydraulic valve. Test for pressure in the lines before
removal.
1. Place an oil pan directly under the hydraulic
valve. This will catch the hydraulic fluid that
drains from the lines and the valve.
2. Remove the double valve clamp from the valve
body using a 7/16 socket. See figure 1.
3. Remove both hydraulic hose connectors coming
from the hydraulic lift cylinder to the valve body.
See figure 1.

8. Remove both hex cap screws and hex flange lock
nuts securing the hydraulic valve to the frame
using a 7/16 socket. See figure 1.
NOTE: The hydraulic valve body must be
secured to the frame with both screws before the
hydraulic tubes can be assembled to the
hydraulic valve during reassembly.
9. Pull the hydraulic valve body away from the
hydraulic inlet tube slowly.
NOTE: If the hydraulic tube does not want to
come out, use a small mallet and tap it out of the
port. Be careful not to damage the valve body or
the hydraulic tube/s.
10. Remove the valve body from the tractor. See
figure 5.
NOTE: Record the correct positions of the nylon
flange bearings on the squared lift link. See
figure 3.
