the rear frame to support the unit. Remove the rear
wheel from side of machine being flow tested; in this
case, the left rear wheel is removed (Fig. 203).
Note: Be careful not to place jack stands near
any moving parts or areas not capable of
supporting the weight of the machine.

2. Clean all dirt and debris away from the hydraulic line
fittings. Remove the hydraulic lines. Make sure you
mark which hydraulic line goes to which fitting on
the wheel motor. If the hydraulic lines are reversed,
the motor will operate in the opposite direction (Fig.
204).

4. Connect the hydraulic hose fittings to the hydraulic
flow tester and tighten the fittings (Fig. 206). If the
