This section covers the removal, repair and reinstallation of the hydraulic pump procedure for the Alamo
Industrial Interstater mower, it also includes instruction for driveshaft, hoses, and miscellaneous parts to be
attached the hydraulic pumps to the tractor.
These instructions are for working on the pumps used to power wing mower/mowers, right side mower, and
left side mower units if dual wing model. For mounting one mower side only, disregard information concerning
the opposite side. Hardware quantities shown are for both sides.
The Auxiliary pump is used to supply the lift and tilt hydraulic cylinder circuit. This auxiliary pump will not
be used on all units, some will use the tractor hydraulic system to supply cylinder circuit.
Reference to the left or right side of the Interstater is determined while facing the front of the tractor from the
drivers seat.
The part quantities shown for an illustration pertain only to that phase of repair. The quantity given corresponds
to the number of parts needed. When repairing a single-sided model based on a dual-sided model, the quantity
furnished will usually be half the quantity listed.
Large parts may not always be listed next to an illustration because they are usually easy to identify them
from name or description.

at the factory.

When installing fasteners, PW and LW (generally installed in that order) are usually on the side of the
fixture or part being fastened that the hex/lock nut is on. When only HHCS, LW and/or PW are required, they
are generally installed in that order. Some parts do not require a PW or LW. Refer to illustrations for exceptions.
Fasteners should be installed so they cause the least interference with other parts. When securing driveshaft
pulley to hub, tighten fasteners to 9 lb-ft torque.
