Description

Westward heavy duty hydraulic transmission jack is designed for lifting and lowering of 
transmissions and differentials from various vehicles ie. car, truck, etc..  They feature a 
wide base to reduce center of gravity and promote stability.  Their super strong 
reinforced steel construction with flanged side frames provide extra strength.  Load 
restraining chains help to assure the user’s safety when lifting and lowering load.  Four 
casters allow easy movement, and easy positioning of transmission jack.  The cradle 
has both side and tilting angle adjusting functions to best fit onto the different shapes of 
various transmissions and differentials.  Patented oil by-pass mechanism offers stroke 
limitation of ram piston.  Durable rust-free enamel finish gives long-lasting quality 
appearance.  Metered release valve assures precise adjustment of cradle height and 
smooth lowering of load.

General Safety Information

Study, understand 

and follow all 

instructions before operating this device.  

Lifting device only.  Intended use is for 

removing, transporting and installing 

transmission or specified components 

only.  Do not lift or support a vehicle with 

a transmission jack.  Immediately after 

lifting, support vehicle with appropriate 

means.  Do not exceed rated capacity.  

Use only on hard, level surfaces capable 

of sustaining rated capacity loads.  Always 

wear safety glasses when using this 

equipment.  Inspect jack before each use.  

Do not use if bent, broken, leaking or 

damaged components are noted.  No 

alteration of this product is allowed.
Do not use this device for any purpose 

other than that for which it was intended .  

Failure to heed any one or combination of 

these warnings may result in severe 

personal injury and/or property damage.

Assembly

Refer to Figure 1.
1. Four pieces of auxiliary fixed 

assemblies and a one-piece handle 
should be included in package.

2. Attach either one of the four auxiliary 

fixed assemblies to the cradle, and 
secure by hex bolts and washers 
provided.  Then apply the same 
procedure for the other assembly.

3. Occasionally hydraulic jacks become 

air bound and will not function properly.  
To correct this condition, remove oil 
filler screw.  This will allow any 
pressurized air to escape.

4. Check for proper oil level (See adding 

oil, Page 2), adjust as needed.  DO 
NOT OVERFILL.  Reinstall oil filler 
screw.

Operation

Off-center loads and 

loads lifted while jack 

is not level may damage the jack or cause 

personal injury.

REMOVING TRANSMISSION/
DIffERENTIAl fROM VEHIClE

1. Close the release valve by turning the 

release knob clockwise.

2. Raise the jack by pumping the jack 

handle until desired height is acheived.

3. Adjust the cradle side position and 

tilting angle to best fit to the shape of 
transmission/differential.

4. Secure the transmission/differential by 

chain and tighten properly.

5. After removing all of the appropriate 

bolts and fasteners which secure the 
load to vehicle, carefully lower the load 
to the lowest practical height.  Move 
load to desired workplace.
