TA40 (A820) Brake & Cooling System
TA40 (A820) BRAKE & COOLING SYSTEM CHECKS
Check pressures when oil temperature is at least 15 to 20°C or ambient temperature if higheron initial start up.
SYSTEM SETTINGS
Priority Un-Loader Valve 170 bar (2465 psi)
Low Temperature Un-Loader Valve 205 bar (2970 psi)
Brake Actuation Pressure 138 bar (2000 psi)
CHECKING SETTINGS
U ENSURE A/C & RETARDER ARE BOTH DIS-ENGAGED1. Ensure Brake Accumulator pressure is dissipated.2. Attach pressure gauge to diagnostic check-point on Brake Manifold Valve, port ‘P1’.3. Start truck and allow pressures to increase with engine at low idle.4. Take note of highest gauge reading. This is the pressure setting of the Priority Un-Loader
Valve.5. Remove electrical connection from Low Temperature Un-Loader Valve. This will render
this valve de-energised.6. Increase engine R.P.M. to full throttle.7. Take note of highest gauge reading – This is the pressure setting of the Low Temperature
Un-Loader Valve.
RESETTING VALVE PRESSURES
Priority Un-Loader Valve TOO LOW
If pressure reading is too low after following steps 1 thru 4, loosen the lock nut on reliefvalve and turn setting screw CW until correct pressure setting is evident. Re-tighten lock nut.
NB. This procedure must be carried out with engine R.P.M. at low idle.NB. All adjust valve pressures on the increase.
Priority Un-Loader Valve TOO HIGH
If pressure reading is too high after following steps 1 thru 4;
(a) Stop engine and deplete brake accumulators.(b) Loosen lock nut on relief valve and turn setting screw CCW 2 to 3 full turns.(c) Re-Start engine and allow pressures to rise with engine in the low idle condition.(d) Note highest pressure on gauge, adjust setting screw CW until correct pressure is
evident.(e) Re-tighten lock nut.

TA40 (A820) Brake & Cooling System
Low Temperature Un-Loader Valve TOO LOW
If pressure setting is too low after following steps 5 thru 7, Loosen lock nut on Relief Valveand turn setting screw CW until correct pressure is evident. Re-tighten lock nut.
NB. This procedure to be carried out with engine at full throttle.NB. Always adjust pressure on the increase.
Low Temperature Un-Loader Valve TOO HIGH
If pressure setting is too high after following steps 5 thru 7;
(a) Bring engine to idle.(b) Depress foot brake pedal several times(c) Loosen lock nut on relief valve and turn setting screw CCW 2 to 3 full turns.(d) Return engine to full throttle.(e) Adjust setting screw CW until correct pressure is evident.(f) Re-tighten lock nut.
BRAKE COOLER FAN CHECK
Check 2 speed function of the Brake Cooler Fan is operating properly.
(a) Disconnect Fan Activation (N.O.) Temperature Switch (50°C) at front axle manifold block.(b) Start engine and allow to idle.(c) Bridge connection on temperature switch harness. This energises the solenoid within the
2 Speed Control Valve.(d) Observe increase in fan speed.(e) If fan speed does not increase, investigate fault on 2 Speed Control Valve solenoid and
associated wiring.
TRIPLE COOLING PUMP/MOTOR ACTIVATION
Check that motor is achieving sufficient pressure to activate triple pump for the brake coolingoil. Check pressure at cooling section of main triple pump.
(a) Connect pressure gauge at diagnostic pressure check point.(b) Start engine and run at full throttle.(c) Observe pressure, typical readings 110 bar (1600 psi)
Additional check; Triple Pump Outlet Pressure @ full throttle = 1.17 – 1.2 bar (17 – 17.5 psi)at each output port.
Maximum allowable pressure across brake packs 1.0 bar (14.5 psi)
