The 6V9433 Crankshaft Removal Group can be used to raise and turn the engine to permit easy removal of the crankshaft. This tool group has been designed primarily for removal of crankshafts from marine engines. However, it can be used in industrial applications where the crankshaft must be removed at the job site.
 |
To decrease the possibility of injury in marine applications, this tool group must be used on vessels at rest and secured to a dock or pier. |

| NOTICE |
|---|
Always connect the lines from the flow divider (27) to the top of the hydraulic cylinder when double-acting cylinder is used. |
|
To prevent personal injury, do not stand beside the engine when it is being rotated, raised or lowered. Do not let the hydraulic pressure to the flow divider exceed the pressure rating of the flow divider. |
|
(17) To rotate the engine, pull pin (7) all the way out, and turn 90° to lock in the "out" position. The pin is used to prevent the engine from accidentally turning, and will lock the engine in 45° increments. Rotate the engine to the desired position by turning handle (29). After the engine has been rotated, turn pin (7) and engage with the appropriate hole in bracket (1).
|
Always have pin (7) engaged with bracket (1) while working on the engine. |
