PRODUCT DESCRIPTION
The Omega Hydraulic Clutch Jack is designed for clutch/ flywheel removal and installation. Intended use: to remove,
install and transport (in lowest position) both 14" and 15-1/2" clutches and flywheels. The two most common spline
sizes, 1-3/4" and 2" diameter, are included with this product. The head plate enables clutch to be positioned in either
horizontal position for clearing underneath vehicle or vertical position for installation and removal. The spline sleeve
rotates 360 degrees, turns side to side and vertically tilts for precise clutch alignment.
DO NOT USE FOR ANY PURPOSE OTHER THAN THOSE USES OUTLINED ABOVE !

(888) 332-6419.
2. Before using this product, read the operator's manual
completely and familiarize yourself thoroughly with
the product, its components and recognize the
potential hazards associated with its use.
3. Open the release valve by turning the release valve
knob counter-clockwise (no more than 1/2 full turn).
4. With lifting arm fully lowered, locate and remove the
oil filler plug. Pump handle 6 to 8 full strokes. Ensure
the oil level is within ~3/16" from the inner cylinder
as viewed from the oil filler hole. Reinstall the oil filler
plug. Close release valve by turning it clockwise until
firm resistance is felt.
5. Check to ensure that jack rolls freely, that the pump
and release valve operate smoothly. Raise and lower
the unloaded jack throughout the advertised lift range
before putting into service.
6. Replace worn or damaged parts and assemblies
with Factory Authorized Replacement Parts only.
Lubricate as instructed in Maintenance Section.
OPERATION
Removing a Clutch
1. Select the correct size spline sleeve. Place the spline
on the adapter shaft, then attach to the head plate
with the release pin & retaining pin provided.
2. Close the release valve by tightening the release
valve knob. Pump the handle to raise the lifting arm
and align the spline sleeve with the clutch.
3. Tilt the head plate with the tilt adjustment bolt to align
it with the clutch bore. Slide the spline sleeve into
the clutch.
4. Remove the clutch mounting bolts and back the jack
and clutch away from the flywheel.
! WARNING
Be sure all tools and personnel are clear before
lowering load.
Transporting the Clutch while on Jack
Be sure the adapter shaft is in the vertical position and
the jack is fully lowered before transporting, as shown
in Figure 2.
! WARNING
• Study, understand, and follow all printed materials
provided with/on this device before use.
•
Do not exceed rated capacity.
•
Use only on hard, level, seamless surface.
•
Do not allow any part of your body under the lift
arm or load while the jack is supporting a load.
•
Use only the factory supplied adapters as a
means of contacting the load. Never use any
other part of the jack as a lifting surface.
•
Use of this jack is limited to the removal,
installation and transportation of clutch/flywheel.
•
Adequately support the vehicle before starting
repairs.
•
Failure to heed these markings may result in
personal injury and/or property damage.
Loading and Unloading a Clutch from the Jack
1. To load or unload a clutch from the jack, be sure the
adapter shaft is in the vertical position, as shown in
Figure 2.
2. Add or remove one piece of the clutch at a time.
Installing a Clutch
1. Raise the clutch into the horizontal position for
installation and tilt the clutch using the tilt adjustment
bolt to align with the flywheel.
2. Put the jack and clutch into position so that the spline

Removing a Flywheel
1. Remove all the flywheel attaching bolts (flywheel to
crankshaft bolts) except for the three bolts pointed
in Figure 4.
2. Close the release valve knob fully. Pump the handle
to raise the lifting arm and align the flywheel adapter
to the flywheel using the tilt adjustment bolt.
3. Center the flywheel adapter to the flywheel and bolt
the adapter to the flywheel. Leave room to access
the remaining three flywheel attaching bolts retained
on the flywheel.
4. Ensure the releave valve knob of the jack is closed

MAINTENANCE
Important: Use only good grade hydraulic jack oil. Avoid
mixing different types of fluid and NEVER use brake
fluid, turbine oil, transmission fluid, motor oil or glycerin.
Improper fluid can cause premature failure of the jack
and the potential for sudden and immediate loss of load.
Mobil DTE 13M or equivalent recommended.
Adding oil
1. With lifting arm fully lowered set jack in its upright,
level position. Locate and remove oil filler plug.
2. Fill with oil until ~3/16" above the inner cylinder as
seen from the oil filler hole. Reinstall oil filler plug.
Lubrication
A periodic coating of light lubricating oil to pivot points,
axles and hinges will help to prevent rust and assure that
wheels, casters and pump assemblies move freely.
Cleaning
Periodically check the pump piston and ram for signs
of rust or corrosion. Clean as needed and wipe with
an oily cloth.
Note: Never use sandpaper or abrasive material on
these surfaces!
Changing oil
For best performance and longest life, replace the
complete fluid supply at least once per year.
1. With lifting arm fully lowered, remove oil filler plug.
2. Lay the jack on its side and drain the fluid into a
suitable container.
Note. Dispose of hydraulic fluid in accordance with
local regulations.
3. Fill with oil until ~3/16" above the inner cylinder as
seen from the oil filler hole. Reinstall oil filler plug.
TROUBLESHOOTING
