If the adjustment is too tight-turn the ring back one notch.5. Install the cover.Generator Set
Your electric set engine may be equipped with a Caterpillar SR4 Generator. The SR4 Generator is a brushless design, and therefore requires no periodic maintenance other than lubrication of the rear bearing. See Lubrication Instructions.The generator serial number is stamped on the generator housing. The first group of numbers, reading from the left, indicates the frame size. Following this number are the letters BS, BH or BG. The letter B indicates the generator is of the SR4 design. The letter S, H or G indicates the voltage rating of the generator. The following numerical digits are the serial number of the generator in that particular frame size and voltage rating. A complete explanation of the numbers and letters in the serial number are found in the GENERATOR SET SYSTEMS OPERATION SECTION. Always use the complete serial number in your communications with your Caterpillar dealer.If you have a generator of other than Caterpillar design, see the Manufacturer's Instructions.
