Parts List & Operating Instructions
1. Verify the handle locking mechanism on the engine
stand is engaged before mounting an engine. Refer
to Figure 1.
. Determine the engine's center of balance (or greatest
2
concentration of weight).
3. Position the engine so its center of balance is located
in the center of the mounting area of the support
plates. See Figure 2.
CAUTION: A load weighing the maximum rated
capacity of 907 kg (2,000 lbs.) must be balanced to
within 51 mm (2.0 inches) of the centerline of the
support plates. An off-center load could cause the
repair stand to be unstable when rotated.
4. Attach the universal mounting arms to suitable
mounting holes. Attach the arms at various angles,
and as far apart as practical for greater supporting
strength.
CAUTION: To prevent personal injury and
equipment damage,
•
Use only metric property class 8.8 or SAE Grade
5 cap screws. Refer to Figure 3.
•
Because of the many different ways to mount
engines, the exact number of mounting arms
needed is hard to specify. However, six (6)
mounting arms are required when mounting
components weighing between 454 kg (1,000 lbs.)
and 907 kg (2,000 lbs.)
5. After the engine and universal mounting arms are
correctly positioned, torque all mounting hardware
cap screws to 82–102 N•m (60–75 ft. lbs.)
6. Verify the engine is securely mounted to the repair
stand and all mounting hardware is torqued.
7. Slowly release the engine from the lifting device.
8. Use the hand crank as necessary to rotate the engine
into an optimum working position.
