MOUNTING INSTRUCTIONS – REMOTE MOUNT

Twin shafted remote mount
pumps require optional

B1235

mounting bracket No.
B1235.

Remove nuts and spacers.
Slide bracket over bolts,
replace washers and tighten
nuts. This procedure does
not open the pump.

Never work on a raised dump bed without proper body props and supports.

Do not use Teflon Tape as a thread sealant. The use of Teflon Tape
will void all warranties expressed or implied for this product.

Always use suction hose (SAE-100R4) on pump inlet.
Three line hook-up requires conversion sleeve No. AA-1257

(AA-1257-2 for the EH) in inlet port. Always route third line so it is
below the oil level at all times.

Two line hook-up has return port plugged and NO sleeve.
Port sizes are different between the E and EH. See drawing at left.
SPECIAL NOTE: For long term product life and improved pump per-

formance always use a three line hook-up. The two line system will
reduce product life. A two line system operated for extended running
times will result in excessive heat build up and subsequent damage.

CAUTION: The relief valve is pre-set at 2000 PSI ± 5%

Adjustable to (but do not exceed) 2500 PSI

WARNING: The rotating shaft between PTO and pump

should be shielded with appropriate guard.

Driveline angles should not exceed 12°.
Maximum speed for solid shafting is
1000 RPM. Consult driveline manufac­turer for specifications. Pump and PTO
shafts must be parallel within 1.5°.

Direct mount pumps are provided with extended studs and extra nuts
for support of pump. A bracket attached to two or more transmission
bolts is required. The bracket design should assure that there is no
stress or force exerted on the pump or PTO shaft. If vertical supports
are greater than 20° off of perpendicular with the transmission main
shaft then a reinforced “Z” bracket must be used. Reinforce horizon­tal members to prohibit flexing at bend or weld.

Attach the bracket at the pump bolt closest to the center of gravity
of the pump. Consult Muncie PTO Owner’s Manual for special rec­ommendations.

Always apply anti-seize grease to shaft splines before installing into
PTO if not done by the manufacturer. Reapply annually or sooner for
severe use. PTOs with greasable shaft splines are available. Contact
Muncie Power Products for additional information.

PULL OUT CABLES (NEUTRAL SAFETY STOP)

This clevis hole is part of a neutral stop device and is provided for

RECOMMENDED

1”

those applications using a “pull-out” cable. This device allows the
cable to move the spool from the raise position to the neutral posi­tion, only. As shock loading is possible, it is essential that a spring
be incorporated in the pull-out cable hook-up. Failure to do so could
result in breakage of the neutral stop device and could lead to injury.
We recommend that the cable be fully enclosed and directly in line
with the valve spool. Use spring part No. PS-1233V.

NOT

RECOMMENDED

NOTE: Never use a pull-out cable on an air shift pump as exact

spool position cannot be adequately controlled. Instead use
1436A-1 safety limit dump valve on raise side of air cylinder.

LEVER CONTROLS

WARNING: If valve is to be shifted by lever and rod linkage type control, the installer is responsible for fitting

the lever with a neutral locking device to prevent the accidental shifting of the valve spool and accidental
raising of the dump body. Muncie offers a complete line of in-cab consoles and controls as listed below.

Lever control rods must be attached to the spool on the front side of pump. Lever control rods cannot be attached
to the spool on the rear side due to the neutral safety stop components. On direct mount units, accessibility to the
spool eye can be improved by ordering kit No. EHK-DR (Discard unused parts).
