PROFESSIONAL LIFTING EQUIPMENT
®
BEFORE USING THIS JACK, READ THIS MANUAL
COMPLETELY AND THOROUGHLY, UNDERSTAND ITS
OPERATING PROCEDURES, SAFETY WARNINGS AND
MAINTENANCE REQUIREMENTS. FAILURE TO DO SO COULD
CAUSE ACCIDENTS RESULTING IN SERIOUS OR FATAL
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
The use of portable automotive lifting devices is subject to certain
hazards that cannot be prevented by mechanical means, but
only by the exercise of intelligence, care, and common sense. It
is therefore essential to have owners and personnel involved in
theuse and operation of equipment who are careful, competent,
trained, and qualified in the safe operation of the equipment and
its proper use. Examples of hazards are dropping, tipping, or
slipping of motor vehicles or their components caused primarily by
improperly securing loads, overloading, off-centered loads, use on
other than hard level surfaces, and using equipment for a purpose
for which it was not designed.
It is the responsibility of the owner to make sure all personnel read
this manual prior to using this device. It is also the responsibility of
the device owner to keep this manual intact and in a convenient
location for all to see and read. If the manual is lost or not legible,
contact Norco Industries, Inc. for a free replacement. If the operator
is not fluent in English, the product and safety instructions shall be
read to and discussed with the operator in the operator’s native
language by the purchaser/ owner or his designee, making sure
that the operator comprehends its contents.
WARRANTY
This transmission jack is covered by a Limited Lifetime Warranty.
For details see the back cover of Norco’s product catalog.
IMPORTANT: READ THESE INSTRUCTIONS BEFORE OPERATING
WARNING
Adequately support the vehicle before starting repairs. Consult•
the vehicle manufacturer for the recommended procedure
for removing and installing transmissions with a floor model
transmission jack.
Once the vehicle is supported, make sure there is enough•
clearance to maneuver the jack and transmission underneath
the vehicle.
Inspect the jack before each use. Do not use the jack if it is•
damaged, altered, modified, in poor condition, leaking hydraulic
fluid or unstable due to loose or missing hardware. Take
corrective action before using the jack.
Do not use jack beyond its rated capacity. Do not lift or support•
the vehicle with this jack.
Use only on a hard level surface.•
Be sure setup is stable and secure. Use this jack only with•
adapters and load restraints provided by Norco. Use of this
jack is limited to the removal, installation and transportation
(in the lowered position) of transmissions and transfer cases.
Center load on saddle. Consult the vehicle manufacturer for the
transmission’s center of balance. Off-center loads can cause
jack failure and/or loss of load.
No alterations shall be made to this jack and use only with factory•
approved adapters.
SETUP
Refer to the exploded view parts drawing for identification,1.
location and position of parts.
The chain and hook are provided in order to secure the2.
transmission to the saddle assembly. The end of the chain should
be anchored to the side of the saddle. The restraint system (chain
and hook assembly) may be adjusted according to the specific
transmission configuration.
Sometimes air gets trapped in the jack’s hydraulic system3.
during shipment. An air bound hydraulic system feels spongy when
pumped and sometimes the jack will not pump full incremental
strokes.
PURGING AIR FROM THE HYDRAULIC SYSTEM
Open the release valve knob by turning it in a counterclockwisea.
direction two full rotations.
Pump the handle 10 to 15 times.b.
Close the release valve knob by turning it in a clockwisec.
direction until it stops.
Pump the handle until the elevator arm is raised to maximumd.
extension. If the condition seems better, repeat steps “a”
through “d” until air is purged from the system.

OPERATING INSTRUCTIONS
Lift the vehicle to the desired work height and support the vehicle1.
in accordance with the vehicle manufacturer’s recommended
support procedure and the warnings given in this manual.
Position the transmission jack directly under the transmission.2.
Turn the release valve knob all the way in a clockwise direction until
it stops. Pump the handle and the saddle assembly will start to rise.
Raise the saddle to a height very close to the center of balance
point of the transmission but do not touch the transmission.
Loosen the four bolts that secure the four extension arms to3.
the saddle. The extension arms are formed in an “L” so that one
arm of the “L” is longer than the other. The extension arms can be
adjusted in and out to help position the transmission on the saddle.
You must determine whether you want to use the long or short arm
of the “L” shaped extension arms. Now gently raise the saddle
so it supports the transmission. Adjust the four extension arms in
position against the transmission and tighten the four bolts that
secure the arms to the saddle. Fore and aft saddle tilt adjustments
are sometimes necessary to properly position the transmission on
the saddle. Side to side tilt positioning may be necessary for the
same reason and can be accomplished by activating the side to
side tilt knob.
The hook end of the chain should be pulled over the center4.
of balance portion of the transmission and secured to the saddle
base. Rotate the hook adjustment to take up the slack in the chain
and secure the transmission to the saddle.
Remove the transmission from the engine according to5.
instructions in the vehicle service manual.
Once the transmission has been disconnected from the engine,6.
very slowly turn the jack’s release knob in a counterclockwise
direction to make sure the jack’s saddle and transmission do not
hang up on any undertruck components, wiring, fuel lines, etc.
Continue to lower the jack all the way down.
PREVENTATIVE MAINTENANCE
Always store the jack in a well protected area where it will not1.
be exposed to inclement weather, corrosive vapors, abrasive dust,
or any other harmful elements. The jack must be cleaned of water,
snow, sand, or grit before using.
Lubricate moving parts once a month with a general purpose2.
grease.
It should not be necessary to refill or top off the reservoir with3.
hydraulic fluid unless there is an external leak. An external leak
requires immediate repair which must be performed in a dirt-
free environment by qualified hydraulic repair personnel who are
familiar with this equipment. Norco Authorized Service Centers are
recommended.
IMPORTANT: In order to prevent seal damage and jack failure,
never use alcohol, hydraulic brake fluid, or transmission oil
in the jack.
Every jack owner is responsible for keeping the jack label4.
clean and readable. Use a mild soap solution to wash external
surfaces of the jack but not any moving hydraulic components.
Contact Norco Industries for a replacement label if your jack’s label
is unreadable.
Inspect the jack before each use. Do not use the jack if any5.
component is cracked, broken, bent, shows sign of damage, or
leaks hydraulic fluid. Do not use the jack if it has loose or missing
hardware or components, or is modified in any way. Take corrective
action before using the jack again.
Do not attempt to make any hydraulic repairs unless you6.
are a qualified hydraulic repair person that is familiar with this
equipment.
