Safety Precautions
The engine repair stand should be used only by
qualified service technicians familiar with this
equipment.
To maintain shear strength specifications, alloy steel
Class 12.9 or SAE Grade 8 or higher cap screws must
be used to mount adapters and engine to repair stand.
Use LOCTITE
242 Thread Lock and Sealer on cap
screws when installing lifting straps on engine. Tighten
cap screws to specifications given.
For full thread engagement, be certain that tapped
holes in adapters and engine blocks are clean and not
damaged. A thread length engagement equal to 1-1/2
screw diameters minimum is required to maintain
strength requirements.
To avoid structural or personal injury, do not exceed
the maximum capacity rating of 2722 kg (6000 lb).
Maximum capacity is determined with the center of the
engine located not more than 330 mm (13 in.) from the
mounting hub surface of the engine stand.
The center of balance of an engine must be located
within 51 mm (2 in.) of the engine stand rotating shaft.
Engine center of balance is generally located a few
millimeters above the crankshaft.
To prevent possible personal injury due to engine
slippage, recheck to make sure engine is solidly
mounted before releasing support from engine lifting
device.
Never permit any part of the body to be positioned
under a load being lifted or suspended. Accidental
slippage may result in personal injury.
The lifting jack is to be used when it is necessary to lift
the engine for rotation. When working on the engine,
the jack should be at its lowest position to keep the
center of gravity and the possibility of tipping low.
To prevent possible personal injury due to sudden
engine movement, lower the engine by operating jack
release valve slowly. Do not unscrew release valve
knob more than two turns from its closed position.
