OPERATING INSTRUCTIONS
1. Upon receiving jack, open release valve and pump
handle several times. This will eliminate any
airbound condition that may have occurred during
shipment.
2. To raise jack, close release valve and operate
pump handle.
3. To lower, open release valve.
FIND CENTER OF GRAVITY
In handling the newer large transmission, it will be not-
ed that they have grown considerably in length. It is
important, first, to gauge as accurately as possible the
center of gravity of the unit to be removed where you
will want to place the jack adapter. On many transmis-
sions this center of gravity is identified by small
projecting lugs on the bottom of the case. On others it
is located on the drawing of the transmission included
in the truck service manual. In any case, you will find it
to be toward the rear of the case, from the center. It is
important that the transmission be generally in balance
when being supported by the jack.
PREPARE TRANSMISSION FOR REMOVAL
1. Prepare transmission for removal in normal
manner, by dropping drive shaft, removing project-
ing levers, accessories ect., and other components
of the truck which might interfere when the
transmission is lowered. If desired, the parking
brake assembly may be removed also.
2. Remove all but three or four bell housing bolts,
leaving those near the top, which can be reached
when the jack is in place.
JACK PLACEMENT AND OPERATION
1. Place jack beneath transmission case as near to
the center of balance as possible. This normally is
rearward of the dimensional center of the unit.
2. Place triangle support brackets against transmis-
sion. Insert four bolts in nearest support plate
holes and fasten with four tightening knobs.
3. Transmission case bottom must rest firmly on jack
support plates. If necessary, due to transmission
case irregularities, the jack adaptor may be tilted
forward, backward, or from sided to side to match
bottom contour of transmission case. his tilt
adjustment is accomplished through adjustment
screw, located on the end of the lift arm below the
adaptor.
4. With transmission bottom on adapter plate, slide
triangle support to firmly support transmission.
(It is important to secure bolt knobs with wrench.)
Securely fasten safety chain to hold transmission
firmly in place while removing.
5. With jack firmly supporting transmission, complete bell
housing bolt removal. Frequently this joint is firmly
stuck together and must be forced slightly to break
loose. This may be done with the jack by raising then
lowering slightly.
6. When transmission has been lowered, it may be
necessary, depending on the size of the unit, to jack
up the front or rear axle of the truck to get the
transmission out from under the truck.
7. Replacement of the transmission is performed in
reverse order to removal. Keep in mind the adaptor
tilt features which permit minute adjustment for
alignment.
SAFETY IN-
STRUCTIONS
1. Do not overload. Overloading can cause damage to
or failure of the jack.
2. This jack is designed for use only on hard level
surfaces capable of sustaining the load. Use on other
than hard level surfaces can result in jack instability
and possible loss of load.
3. When the jack is used for transporting a load, the lift
arm must be in its lowest position. Roll only on hard
level surface free of excessive crevices or
obstructions.
4. Failure to heed these warnings may result in loss of
load, damage to jack and/or failure resulting in
personal injury or property damage.
