How do you start a CAT motor grader?
How do you start a CAT motor grader?
In neutral and with the parking brake on, open the throttle to a quarter and turn the starter. Depress the clutch to ease the starter load, and don’t press on the starter for more than 30 seconds. If you do, you may need to wait a couple minutes before using the starter again.
How does a pony motor work?
The pony motor is a small gasoline engine nestled up under the dash. The operator would start this little gas engine and use it to warm the big diesel engine. When the engine was warm enough, the operator started the diesel engine and turned off the gasoline engine.
What is a donkey start diesel?
It is the small 2 cylinder gas engine that turns over the diesel until the diesel warms up enough through friction to start when the throttle is opened. Back to top. RowanH.
What year did Caterpillar stop using Pony Motors?
Generally speaking, Cat phased out the pony engines in the early to mid ’60’s, and by the late ’60’s they were pretty much gone as an option on a new machine.
What is the purpose of pony motor?
Pony motors are small motors mostly induction motors,which are used to run the rotor near to the synchronous speed. Once the rotor attains the synchronous speed, the d.c. excitation to the rotor is switched on. Pony motors are connected to the shaft of synchronous motor only up to it attains synchronous speed.
When did they stop using Pony Motors?
What is a pup engine?
Probably not used anymore but in the past it was a small gasoline engine that would be used to turn over the main diesel till it started. This little gas engine would start easily exspecially in cold weather. Almost all the “Cat Equipment” had this feature, as I recall. Also called a pup motor.
What is meant by donkey engine?
1 : a small usually portable auxiliary engine. 2 : a small locomotive used in switching.
How does a synchronous start?
The motor is first started as a slip ring induction motor. The resistance is gradually cut-off as the motor gains speed. When it achieves near synchronous speed, DC excitation is given to the rotor, and it is pulled into synchronism. Then it starts rotating as a synchronous motor.
