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
the use and operation of equipment who are careful, competent,
trained, and qualied in the safe operation of the equipment and its
proper use. Examples of hazards are dropping, tipping, or slipping
of engines 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,
contactNorcoIndustries, Inc. for afreereplacement. If the operator
is not uent 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.

IMPORTANT: READ THESE INSTRUCTIONS BEFORE OPERATING
WARNING
Inspect the engine stand before each use. Do not use the•
engine stand if it is damaged, altered, modied, in poor
condition, leaking hydraulic uid, or has loose or missing
hardware or components. Take corrective action before using
the engine stand.
Do not use the engine stand beyond its rated capacity. The• maximum capacity (6000 lbs.) is determined at a point where
the center of the engine is located no more than 13” from the
mounting hub surface. The engine stand is equipped with
a universal adapter that bolts to the mounting hub surface.
Center lines of engines weighing 5000 lbs. can be mounted no
more than 20” from the mounting hub surface and center lines
of engines weighing 4000 lbs. can be mounted no more than
25” from the mounting hub surface.
Use only on a hard level surface.•
Wear approved eye protection.•
Assure load is centered and secured to mounting adapters.• Consult the engine manufacturer for the proper engine
mounting hole locations.
Use only grade 8 bolts in all adapter and engine mounting• applications. Before handling and/or starting repairs, make sure
all hardware is tight and secure.
Threaded holes in adapters and engine blocks must be clean• and not damaged to insure thread engagement. A bolt thread
engagement must be equal to 1-1/2 times the bolt thread
diameter in order to maintain strength requirements.
Lock the rotating gear drive by engaging the crank handle with• the locking fork before applying a load to the engine stand and
working on the engine.
Avoid unsafe, off-balance loads by aligning the engine’s center• of balance (rotational axis of the engine) with the rotational axis
of the engine stand’s gear drive shaft. The center of balance
is generally a few inches above the crankshaft. The alignment
should not be off more than two inches. Consult the engine
manufacturer to determine the exact center of balance.
Keep body from underneath engine when being lifted or• suspended.
The engine stand’s hydraulic jack is only used to gain engine• clearance when rotating the engine. Keep the jack at its lowest
possible position when working on an engine in order to avoid
tipping. Always release the jack slowly and carefully when
lowering a load.
No alterations should be made to this product.•
Only attachments and/or adapters supplied by Norco shall be• used.
SETUP
This engine stand is equipped with a universal adapter which1.
can be congured to t certain engines or certain optional engine
adapters. Determine the correct adapter for the engine you are
working on and tighten all hardware that attaches the adapter to
the engine stand’s mounting hub.
Sometimes air gets trapped in the hydraulic jack that controls2.
the angle of the mounting hub.An air bound hydraulic system feels
spongy when pumped and sometimes the jack will not pump in full
incremental strokes.
PURGING AIR FROM THE HYDRAULIC SYSTEM
Open the release valve by turning the handle in aa. counterclockwise direction two full turns.
Pump the handle ten full strokes.b. Close the release valve by turning the handle in a clockwisec. direction until tight.
Pump the jack until the ram is extended to maximum height.d. If the condition remains, repeat steps “a” through “d” until alle. air is purged from the system.
Note: Revision letters (A, B, C, D etc.) after model numbers have been omitted as they do not affect the setup,
operating and maintenance instructions of a particular jack unless otherwise noted.
