Changing Valves

vALvE BODy mODIFICATIONS

There are two major modications, the rst is to swap out the trim valves and place springs in front of the trim
valves before replacing them. It is a good idea to rst full swap out the A Trim side and replace it before starting
on the B Trim side to reduce the chance of loosing parts or mixing things up. The second is to drill out two holes
in the separtor plate to supply more oil.

1. Remove the A Trim solenoid and the 2 valves and 2 springs.

2. Replace the parts in the order shown in the Trim Valve Diagram using the Bully Dog A Trim valve. The A Trim
valve is the valve with the rib.

3. Remove the B Trim solenoid and the 2 valves and springs.

4. Replace the parts in the order shown in the Trim Valve Diagram using the Bully Dog B Trim valve. The B Trim
valve is the valve without the rib.
