Relief Valve Adjustment
First remove the rear cover support. The Reverse valve is on the top and the Forward valve is on
the bottom (a small amount of fluid will drain when the bottom valve is removed, so have a drain
pan handy).
Next, remove the plug with a 10mm Allen wrench, then remove the spring and the valve. To
remove the top valve you will need a strong magnet or small needle nose pliers (to remove with
pliers, carefully grasp the locking screw). Next securely grasp the base of the valve in a vice.
Loosen the locking screw (counter clockwise) with a 2.5mm Allen wrench. Carefully grasp the
tension cap with pliers and turn clockwise 1 turn (it is helpful to mark the cap with a marker for a
reference point). Tighten the locking screw and reassemble. After both valves are done, reinstall
the rear cover and support. Check Hydro fluid and fill as needed (see owners manual for fluid
type).
* On RTV900 it may be helpful to remove the 4 mount bolts on Aux. Hyd. tank and slide over to
have room to get to the Reverse Valve.
