What do you use to connect a single-bearing generator to a Caterpillar Engine to form a generator set? Then what do you use to control the shaft vibration caused by the out-of-balance condition of the generator so the vibration will not cause damage to the set?
If you use a current Caterpillar generator, the necessary parts are shown in the engine Parts Book. But what do you do if the Caterpillar Generator is not a current model? Or what if the generator is not a Caterpillar Generator? Then you need the February 1977 revision of Engine Data Sheet (EDS) 72.1.1, Form No. LEHQ1481.
The newest EDS 72.1.1 tells how to get a generator shaft into alignment with the engine crankshaft and how to control the vibration. Drawings and charts show how to find dimensions and clearances. Other charts show part numbers needed, including flywheel balance weights and bolts.
The Data Sheet also has instructions on removal of any balance weight from the flywheel of a generator set engine that is test run without the generator. But caution must be taken to install the balance weight again before the generator is connected. And no change of balance weight parts (for example, a longer or shorter bolt) can be permitted.
In addition, the Data Sheet tells how to reestablish (put back) the original alignment with plastic shims when wear to a pilot (guide) shaft and the flywheel bore causes too much out-of-round.
EDS 72.1.1 is an important part of the Engine Technical Manual. Be sure you have the February 1977 revision.
The charts from EDS 72.1.1 are also shown on microfiche in the Technical Information File.
Both the Engine Technical Manual and the Technical Information File are available from the Industrial Division of Caterpillar.
Never assemble a single-bearing generator and a Caterpillar Engine into an electric set until you have read EDS 72.1.1. Wrong installation can damage both the generator and the engine.
