LEFT HAND FORK SIDESHIFT CYLINDER DOES NOT OPERATE - continued

TM 10-3930-673-20-1

NOTE

Hydraulic oil pressure should be checked only while engine is idling with no controls operated. If a function is

operated, the pressure will rise up to 3625 psi.

PISTON PUMP

PRESSURE TEST

(1) Remove cover from diagnostic coupler

on piston pump.

(2) Perform STE/ICE Test #51

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

(3) Read output pressure on test device.

(a) If hydraulic oil pressure is 160 psi

(1103.2 kPa), go to Step 5 of this

fault.

(b) If hydraulic oil pressure is not 160

psi (1103.2 kPa), shut down engine

(TM 10-3930-673-10) and test and

replace piston pump (Para 18-4).

ATTACHMENT CONTROL VALVE

PRESSURE TEST

(1) Remove cover from diagnostic coupler

on attachment control valve.

(2) Perform STE/ICE Test #51

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

(3) Read output pressure on test device.

(a) If hydraulic oil pressure is between

160 and 3625 psi (1003.2 and

24994.4 kPa), go to Step 6 of this

fault.

(b) If hydraulic oil pressure is not

between 160 and 3625 psi (1003.2

and 24994.4 kPa), shut down

engine (TM 10-3930-673-10) and

replace attachment control valve

(Para 18-6).
