The new engine as sent from the factory will not necessarily have the same BHP (brake horsepower) as your old engine. The correct low idle and high idle rpm and the fuel setting for your machine are given in the FUEL SETTING INFORMATION. Check these settings and make the necessary adjustments before the engine is put into steady operation. It must be remembered that because of the differences in the engine models, arrangements, and applications, it will be necessary to always check and/or adjust the high idle and low idle rpm and the fuel setting before the engine is put to use in normal operation.
For those engines that were equipped with glow plugs, either remove the wire from the heat-start switch to the glow plug lead assembly, or put tape over the end of the wire when it is disconnected. This wire will not be needed because the new engine does not have glow plugs.977L Track Loader
