If the base (2) of the electric set is fastened to a foundation, loosen all the bolts that connect the base to the foundation. Loosen all bolts that fasten the generator supports (3) and engine supports (1) to the base (2).
Ensure that there is clearance between the bolts and the bolt holes in the base, the engine supports and the generator supports at all locations.
Check the clearance between the base (2) and the foundation at all mounting locations. Shims should be used in order to prevent the deflection of the base (2) as the bolts that connect the base to the foundation are tightened. When there is no deflection of the base, tighten all bolts that connect the base to the foundation to the final torque.

Check the clearance between the base (2) and the engine. Check the clearance between the base (2) and the engine supports (1). Check the clearance between base (2) and the generator supports (3). Check the clearance over the entire length of the supports. This is especially important on generators with long supports (4), since some of the surfaces may not be square or parallel. Shims should be used in order to prevent the deflection of the supports as the bolts are tightened. After all the necessary shims have been installed, finish tightening all mounting bolts to the final torque.Alignment Of Electric Sets With Supports At The Flywheel Housing

If base (1) of the electric set is fastened to a foundation, loosen all bolts that connect the base to the foundation. Loosen all bolts that fasten the engine supports and generator supports to the base.
Ensure that there is enough clearance between the bolts and the bolt holes in the base, engine supports and generator supports at all locations.
Check the clearance between the base (1) and the foundation at all mounting locations. Shims should be used in order to prevent the deflection of the base as the bolts that connect the base to the foundation are tightened. When there is no deflection in the base, tighten all bolts that connect the base to the foundation to the final torque.

While the generator is still supported by the crane, loosen all bolts (2) that fasten the generator to the flywheel housing. Tighten alternate bolts to the final torque. Check the clearance between the base and the engine and generator supports at all four locations. Check the clearance over the entire length of the supports. This is especially important on generators with long supports (3). Shims (4) should be installed until all of the mounting surfaces are flat and parallel.

Tighten all bolts that fasten the engine supports and the generator supports to the base to half of the final torque. Loosen all bolts (2). Measure the gap between the generator and the flywheel housing . Visually ensure that the bolts (2) are centered in the
