Choke (30)
3. Determine the thread type and length of
bolts (not included) needed to thread into the
engine block. Use grade 8 bolts that are long
enough to fit through the Arms and thread as
deeply as possible into the engine block.
4. Loosen bolts holding Mounting Arms (25) and align
them with four mounting bolt locations on the engine.
WARNING! TO PREVENT SERIOUS INJURY: Use all
four Arms when attaching an engine to the Stand.
5. Place the bolts (not included) through the Mounting
Plate (24) side and securely tighten them into the engine.
The bolt heads must press against the back of the Arms:
if needed, use flat washers (not included) as spacers.
6. Tighten the Bolts (37), Nuts (38), and Washers
(36, 29) that hold the Mounting Arms (25)
to the Mounting Plate (24) securely.
7. Slowly lower the hoist/engine crane (sold separately)
until all the engine’s weight is held by the stand.
8. Safely release the engine from the hoist/engine crane.
9. Slowly rotate the engine to the desired angle and
insert the Choke (30) into the top of the Column (2).
Figure F: Choke (30) Location
Rotating Engine
TO PREVENT SERIOUS INJURY: Be prepared for sudden engine movement before removing Pin.
Stay clear of engine.

turn the crank. This will rotate Mounting Plate
with load attached in desired direction.
2. Use extreme caution while rotating the Handcrank.
Removing Engine
1. With assistance, rotate the engine to its initial position.
2. Secure the engine properly to the crane.
Use the crane to support all of the engine’s weight directly
overhead, but do not start lifting the engine stand.
Page 4 For technical questions, please call 1-888-866-5797. Item 57745
3. Once the engine is properly supported by the crane, remove
the bolts securing the Mounting Arms (25) to the engine.
