NOTE: The three wheel motors on the ProCore 648 are
similar in construction but are different from each other.
The front wheel motor (24 c.i. per revolution) has a differ-
ent displacement than the rear motors and has a count-
er–clockwise direction for the forward direction. The
right and left rear wheel motors have the same displace-
ment (12 c.i. per revolution) but have different rotation
for the forward direction: the right rear has a clockwise
drive direction for forward and the left rear has a count-
er–clockwise direction. Displacement and primary rota-
tion (forward) direction are identified on the motor name
plate.
NOTE: For repair of the wheel motors, see the SAUER
