Engine Mounting/Install 400 Series Adapters on Repair Stand SAFETY PRECAUTIONS • The engine repair stand should be used only by qualified service technicians familiar with this equipment. • To avoid an unsafe off-balance load condition, 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 maintain shear strength specifications, alloy steel 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 170 N·m (125 lb-ft). • To prevent possible personal injury due to engine slippage, recheck to make sure engine is solidly mounted before releasing support from engine lifting device. 03 2 • 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. • 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 low and the possibility of tipping low. • 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. • To prevent possible personal injury due to sudden engine movement, lower engine by operating jack release valve slowly. Do not unscrew release valve knob more than two turns from its closed position. LOCTITE ® is a registered trademark of Loctite Corporation.
