Engine controllers can sometimes be a difficult and stressful part to find. The information below will help guide you determine what controller, you have in your generator, as well as, what start/stop switch is required.

ECU 63CONTROLLER
The 07CONECU63 engine control module (ECM) runs on a momentary start/stop switch with an LED light located in the rocker switch.  To learn more about the momentary switch, please click on the part number: 05SR

ECU 64 CONTROLLER
The 07CONECU64 engine control module (ECM) runs on a maintain start/stop switch with an LED light located in the rocker switch.  To learn more about the maintain switch, please click on the part number: 05SRMT

12V CUBE RELAY CONTROLLER
12 volt cube relays were used on the CD model generators until 2004. There are 3 cube relays per unit. A white momentary rocker switch or momentary 3-way toggle switch was used to operate the generator.  To learn more about the momentary white rocker switch, please click on the part number: 05SRMOMWB.  To learn more about the momentary toggle switch, please click on the part number:  05STOGMOM6P.

Power Tech has two sizes available when it comes to the CD radiators. From top to bottom, the measurement will be 13 inches (03RAD500) or the measurement will be 16 1/2 inches (03RAD800). 

Power Tech has two configurations when it comes to the upper and lower radiator hoses. If the upper and lower hoses are on the same side of the engine, it will require two of the lower hoses (03HSCDL). The top hose is cut to fit, but has the same bend as the lower hose. If the upper and lower hoses are on opposite sides from each other on the engine, it will require one lower hose (03HSCDL) and one upper hose (03HS7CDU).  

There is also an upper bypass (03HSBYP05U) hose and a lower bypass (03HSBYP05L) hose on the CD models. Note that the lower bypass hose is part of the lower radiator hose system. You will have the lower radiator hose coming off of the radiator, then it is connected to a metal hose. From there, it goes to the lower bypass hose and back to the water pump (03PW05KIT).

Kubota has two different size thermostats on the 05 series Kubota engines. The best way to tell the difference between the two is to measure the thermostat housing mounting bolts center to center. The measurement on the thermostat housing bolts will measure 2" on center (03THM905K) or it will be 2 3/8" on center (03THM0305NEWK).

If your generator has a brush type generator, you will need the 06REG21. If your generator is brush-less or an Exciter type generator, you will need the 06REG24.

The same information used for the generator voltage regulators are used for picking the correct end bearings. If your unit is a Brush-type generator, you will need the 02BRG6304 bearing. If your unit is an Exciter type generator, you will need the 02BRG6206 bearing.

If you have a brush type generator, there are three possibilities for the brush assembly. If the original brushes are on the unit. Look at the color of the brush housing. It should be brown, black, or white. If the brushes are brown or black, check the springs. The springs will be internal or external (looks like a coiled clock spring).

Note: If you've already changed your brushes, please take a measurement from the two mounting holes. All replacements are white in color.  

TEMPERATURE SWITCH
The 05STKUB1P is the only replacement for the CD model generator. 

SINGLE POST OIL PRESSURE SWITCH
The 05SOKUB1P Kubota oil pressure switch is one of two options for the CD7000 and CD8000. This part is usually located above the oil filter on the side of the generator. This oil pressure switch has a single post for the wire connection.

TWO POST OIL PRESSURE SWITCH
The 05SO2P oil pressure switch is one of two options for the CD7000 and CD8000. This part is usually located above the oil filter on the side of the generator. This oil pressure switch has two posts for the wire connection.
