Mc Leod Piston Seal Replacement - Manual

Hydraulic Bearing Piston and Seal Replacement Instruction
The McLeod hydraulic throw out bearing assembly is adjustable by easily changing the piston in the
assembly. The seals can easily be replaced and serviced by the installer as well. This instruction is
intended to make this process easy to understand and reassemble the hydraulic throw out bearing
correctly.
Step 1 Remove the bearing assembly from the transmission. Place caps over the end of the AN-4 hose to
keep from dripping oil onto the floor and work surface.
Step 2 Grab the bearing and firmly pull to remove the bearing from the hydraulic assembly. It is only
held in position with an O-Ring. Set the bearing aside. See Figure 1

Step 3 If you are disassembling a Slip-On style bearing you will need to remove the 8 screws from the
bottom of the bearing assembly to disassemble the unit. See Fig 2
To separate the Upper and Lower Housings turn bearing assembly over with the lower housing facing up.
Hold a hose in each hand. Drop bearing assembly so piston makes contact with a 2 x 4 piece of wood.
This may require two attempts. This should separate the upper and lower housing. Do not attempt to
wedge the Upper and Lower housings with a screw driver or similar metal tool! See Figure 3.
Pull the two pieces apart exposing the black piston. Remove the piston from the housing.
If only changing Pistons skip to step 10.
