OVERDRIVE 9
Governor Operation Inspection: Suspend
the axle and operate the engine at low
speed in high gem*. Apply a test lamp
across the governor contact from the live
terminal "H" to the ground strap. The test
lamp should light. Now increase engine
speed. The governor cut-in speed will be
indicated when the light goes out.
Summary
By following the above procedure in the proper
sequence, the defective portion of the elec-
trical circuit can be readily located. If all
the preceding items are functioning correctly,
the trouble may lie in the solenoid itself,
such as burned points, or the connecting wires
may be grounded to the case.
The kickdown switch should be carefully
inspected to see that none of its four
terminals are touching each other. If the
terminals "E" and "J" make contact, the
grounded circuit will supply current to the
relay, operating the solenoid without the
possibility of disengage. ment. This is
usually the case when the car will not free
wheel or shift into reverse.
A rubber boot has been provided to exclude
water and dirt from the governor. Moisture or
an accumulation of foreign matter may ground
the line terminal on the governor and cause the
solenoid to operate as soon as the ignition is
turned on.
If the mechanical and operating checks do
not reveal the difficulty, internal trouble
should be suspected and the transmission and
overdrive removed for examination.
DISASSEMBLING THE OVERDRIVE
NOTE: Due to the similarity of the
"Hornet," "Wasp", and "Rambler" Series
Overdrive Units in appearance and opera-
tion, most of the illustrations shown
refer to the "Hornet" Series.
The transmission and overdrive is removed from
the car as a unit. However, it is not necessary
to disassemble the transmission in order to
overhaul the overdrive unless the transmission
main shaft, the bearing in the adapter, or
other transmission parts require replacement.
With the transmission and overdrive assem-
bly drained of its lubricant and set up in a
transmission stand, remove the torque tube
adapter ("Hornet" and "Wasp" Series only)
(Fig. 10).
Then remove the governor and drive unit
assembly from the case (Fig. 11).
Removing the Overdrive Rear Oil Seal and
Adapter
The "Hornet" and "Rambler" Series rear oil seal
is pressed into an oil seal adapter. The
adapter can be removed from the overdrive case
by using Tool J-2497
1. Governor Assembly
FIGURE 11— Remove Governor Assembly
(Fig. 12). Tool J-2619 and J-4830 is used to
remove the oil seal in those cases where only
the replacement of the seal is required (Fig.
13).
On the "Wasp" Series, the oil seal is
pressed into the case and can be removed by
using Tool J-2619 and J-4830 (Fig. 13).
After removing the oil seal and/or
adapter, remove the main shaft snap ring
(Fig. 14).
Disengaging the Shift Shaft
Drive out the lock pin that holds the
overdrive shift shaft in the overdrive case
(Fig. 15).
After the lock pin has been removed, pull
the shaft toward the outside of the case;
this disengages the shift shaft from the
shift rail.
