ALE then carried out the procedure in reverse to transport and position the new crankshaft under the engine block. The crankshaft was lifted back into its bearings using the chain hoists. To complete the crankshaft exchange, the engine block was jacked-down and adjusted into its final position.
For the removal of the rotor, ALE first used single acting jacks with specially-designed jacking brackets to jack-up the alternator housing by 30cm. This enabled ALE to move the rotor just above the foundation and assist the client with the removal of the bearings and end shields. Extension pieces were attached to the shaft of the rotor, which ALE lifted using 20t capacity chain hoists, enabling the rotor to be removed from its housing.
Once outside the alternator, the rotor was set down on roller skate brackets, so it could be rotated for the client. After the client had completed their work, ALE reinstalled the rotor in its housing and it was jacked-down.
