PRESSURE TEST (CONT)

In the event of a tachometer failure, a

HAND THROTTLE lever positioned to full

down is approximately 750 RPM.

(18) Set engine speed to idle 750 RPM

(TM 9-2320-366-10-1).

(19) Position PTO switch to off

(TM 9-2320-366-10-1).

(20) Shut down engine (TM 9-2320-366-10-1).

NOTE

Keep tachometer within 1,250-1,450

RPM when PTO is engaged.

Failure to

comply may result in damage to

equipment.

In the event of a tachometer failure, a

HAND THROTTLE lever positioned to L

is approximately 1,250-1,450 RPM.

(13) Set engine speed to 1250-1450 RPM

(TM 9-2320-366-10-1).

Hydraulic oil temperature must be

145°F-155°F (63°C-68°C) prior to

performing troubleshooting checks.

Failure to comply may result in

inaccurate test results.

Holding DUMP BED UP/DOWN switch

in the UP position will force hydraulic

oil through relief valve and cause oil

temperature to rise.

Measure hydraulic oil temperature near

bottom of hydraulic reservior.

(14) Attach a temperature indicator sticker to

hydraulic oil tank.

(15) Press and hold DUMP BED UP/DOWN

switch in the UP (TM 9-2320-366-10-1)

position until hydraulic oil temperature

reaches 145°F-155°F (63°C-68°C).

(16) Perform STE/ICE Test #51

(TM 9-4910-571-12&P).

(17) If 2,726-2,975 PSI (18,789-20,511 kPa) is

not present, replace four way relief valve

(para 17-3).
