according to the Kohler explaination of model code: 8.5CMO61
Explanation of Model Code:
In models below 1000watts, first numerals indicate capacity in watts. In models starting at 1000 watts,first numerals
indicate capacity in kW.
The first letter following numeral indicates method of starting:
A Automatic
C Push Button at Plant
D Manual
R Remote Control
The second,third and fourth letters indicate special modifications:
B Briggs & Stratton
C 12VoltCranking
D Detroit Diesel
F 50Cycle
H Housing
K Kohler Engine
L Liquid Cooled
M Air Cooled
O Diesel Fuel
P Perkins
S 3600RPM
T 1200RPM
V 180Cycle
W Wisconsin Motors Engine
Y Rotating Field
Z Fast Response/Brushless
Second last numeral indicates voltage,phase,wires:
01 120/240VoltAC,3Phase,4Wire
21 120VoltAC,1Phase,2Wire
31 120VoltAC,3Phase,3Wire
41 240VoltAC,1Phase,2Wire
51 240VoltAC,3Phase,3Wire
61 120/240VoltAC,1Phase,3Wire
71 277/480VoltAC,3Phase,4Wire
81 120/208VoltAC,3Phase,4Wire
91 347/600VoltAC,3Phase,4Wire
Last number will indicate method of cooling and fuel:
1 GasolineorDiesel
2 CombinationGas/GasolineorStraightGas
3 Marine,HeatExchanger
4 CityWaterCooled,GasolineorDiesel
5 Gasoline,Portable
6 Gas,Portable
7 DirectWaterCooled,KeelCooled,RemoteRadiator
8 CityWaterCooled,Gas
So, it was originally push button start, air cooled diesel, single phase, 120/240, 3 wire. Is this still correct? (I have no idea what I'm looking at!
