When the oil is cold and pressure differential across the oil cooler is higher than 6 bar ( 87 lbf/in2 ) the cooler by-pass
valve (1) located in the transmission top cover will operate to ensure that adequate flow to the lubrication circuit is
maintained. This feature of diverting oil from the cooler assists in aiding a rapid warm up of oil in cold weather con-
ditions.
The steering pump / steering return oil is directed through the oil cooler at the front of the tractor and is limited to a
maximum pressure of
5.59 bar ( 81.06 psi )) by the lubrication relief valve located in the transmission top cover.
