Gearbox Oil Temperature - Valtra 6000 Workshop Manual

33. Agroline ---instrument
C. Gearbox oil temperature B3
(for monitoring gearbox oil temperature)
IMPORTANT! Agroline ---instrument shows a fault code, if
this sensor is faulty, see page 333/6.
Mezzo/Mega
Position of the sensor:
--- In Mezzo/Mega: on the lower face of the servo valve
block
--- In HiTech: on the outer face of the servo valve block
Note! The gearbox oil temperature must be higher than
+40˚C, before the instrument shows the temperature value.
In lower temperatures LO (=LOW) is visible in the display.

If the display does not show the temperature value, check
the sensor wires and the sensor.
Sensor resistance values:
+60 ˚C = 221.2 Ω ±26 Ω (±4 ˚C)
+90 ˚C = 83 Ω ±8 Ω (±3.5 ˚C)
+120 ˚C = 36.5 Ω ±2.7 Ω (±3.5 ˚C)
The resistance can be measured between pin X26/6 and
frame contact. If the value is infinite, the resistance must be
measured on the sensor pins.
Due to manufacturing tolerances of the sensor B3 for in-
strument display, the display value can deviate a bit before
the warning light of the sensor S16 comes on.
If the gearbox oil temperature is continuously very high
(e.g. +90˚...+99˚C), check the cleanliness of the oil cooler
and the transmission oil level. If the gearbox oil level is at
"extra max" line, the oil overheats easily in high loads and
at high driving speeds. In some cases it can be useful to
reduce the oil level down to "min" or "max" line of the dip-
stick. If there is too little oil in the gearbox, it must be
HiTech
topped up to the dipstick lines.
