MODEL DESIGNATIONS

Like me, you're probably confused by the various Kohler model numbering systems and
what they mean. Here is a brief run-down of what I have managed to sort out so far.
A LOT of this information is from Mike Shearer of Phoenix, AZ.
1st Digit (or Digits) Output of the generator set in kVA (AC Sets or Watts (DC Sets)
2nd Letter 'A' is for AUTOMATIC starting or stand-by set, applies to EARLY sets.
" " 'B' on earlier sets indicates automatically controlled start-up and stop (For battery charging)
" " 'C ' on earlier sets indicates Push-Button start at plant
" " 'E' is for emergency automatic starting with load transfer.
" " 'G' indicates 'General Motors' - presumably a special model?
" " 'H' is for hydraulic starting.
" " 'J' is for 28V DC Battery Charging, push-button start.
" " 'K' is for Kohler engine.
" " 'L' on earlier sets indicates push button at plant & Limited remote control (start and stop)
" " 'M' is for MANUAL starting, hand or rope. Also applies to ALL sets.
" " 'N' is for 6-Cylinder engine, 15kW sets only.
" " 'O' is for Diesel or Kerosene fuel.
" " 'P' is for Perkins engines (UK).
" " 'R' on later sets indicates remote control (start and stop)
" " 'S' is for specific or special engine rpm.
" " 'T' is for 1400 Engine rpm.
" " 'U' is for 40Hz output frequency.
" " 'V' is for 180Hz output frequency.
" " 'W' is for Wisconsin engine.
" " 'X' is for Horizontal engine.
" " 'Y' is for Rotating Field generator.
" " 'Z' is for brushless / fast response.
3rd Letter 'B' on later sets is for Briggs & Stratton engines.
" " 'C' is for 12V Electric Start. Applies to later sets, early sets see above.
" " 'F' is ALWAYS for 50Hz running, applies to both early AND later sets.
" " 'H' - Sheet Metal housing.
4th Letter Another 'M' later in the part number denotes an air-cooled engine, later sets only.
2nd-Last Digits '21' is for standard USA rating 120V 2-Wire 60Hz
" " '31' is for 120V 3-phase 3-wire (with an 'F' in the number this would be 50Hz)
" " '41' is for standard European rating 240V 2-wire (With an 'F' in the number this would be 50Hz)
" " '51' is for 240V 3-phase 3-wire (with an 'F' in the number this would be 50Hz)
" " '61' is for 120/240V 1-phase 3-wire (with an 'F' in the number this would be 50Hz)
" " '71' is for 277/480V 3-phase 4-wire (with an 'F' in the number this would be 50Hz)
" " '81' is for 120/208V 3-phase 3-wire (with an 'F' in the number this would be 50Hz)
" " '91' is for 348/600V 3-phase 4-wire (with an 'F' in the number this would be 50Hz)
" " '101' is for a special voltage (with an 'F' in the number this would be 50Hz)
" " 'B' is for 140V (Nominal 110V) DC Battery Charging.
" " 'D' is for 40V (Nominal 32V) DC Battery Charging.
" " 'E' is for 12V DC Battery Charging, push-button start.
" " 'G' is for 6V DC Battery Charging, push-button start.
Last Digit '5' is for Gasoline engines, portable unit. Later sets only.
" " '1' - Gasoline or Diesel
" " '2' - 2 Combination gas/gasoline or Straight gas
" " '3' - 3 Marine
" " '4' - City water cooled, gasoline or diesel
" " '5' - Gasoline, portable
" " '6' - Gas, portable
" " '7' - Direct water cooled or keel cooled
" " '8' - City water cooled, gas

There MAY BE exceptions to the above!
