RADIATOR & HOSE
All Except Model G
130.
Method of removing the radia-
tor is self-evident after examining the
tractor. On B, C, and RC, the radiator
shell can be removed without disturb-
ing the core and tank unit and the
shutters can be removed after remov-
ing the shell. On the RC, WC, WD,
WD45, and WF, the shell and/or shut-
ters if so equipped can be removed
only after removing the radiator as-
sembly from the tractor.
On WC, WD, WD45, and WF, the
best method for renewing the lower
radiator hose is to remove the water
pump.

move engine hood and disconnect the
brake return springs from lower side
of radiator. Drain radiator and remove
