Proper way to start a Caterpillar D 2 with a pony motor

[basshunter]

"Old school always rules" when it comes to reliability! In today's machines you have at least a dozen sensors that are prone to failure along with lord knows how many power/ground connections! Simple is always better when you need a job done right and right away! Great vid! 👍

Those silly ole slide rule engineers who's designs still work 70 years later. Man I love old tech !

When I was five or six my father ran a cat with a pony starter. I haven't heard the sound of a pony starter in over 60 years. Thanks for the great video and memories.

Thanks for explaining the whole thing before starting that pony motor. You're right that little thing makes such a racket you can't hear anything else.

[bananas]

Thanks for the memories. That was the high point of any week (1950's New Zealand) when the D 2 got a start up to do some work. When I was 10yrs old I was allowed to drive it from time to time - so cool!

Brings back memories, thanks for sharing the results of obvious hard work getting here...

Nice old machine, looks to be in good shape. Very nice and informative video!

Back in the late 70’s I bought a old road grader with a pony motor. At a auction. Wish I’d had these instructions on starting it then. I was blind to how it worked. Finally recruited someone to show me. Hard to resell something when you don’t know how it works.
I could use a little Cat a round here at times. But don’t need that one

I like the explanation provided. It allows your audience to better understand the working operation of the staring process.

I was interested to see how it was done. I had never even heard of a starting system like this until I saw the old movie "Killdozer". The D9 😉💪

Great fun. Great to watch. Well done. The reason that these engines went so well was the warm oil circulated before the load was applied to the engine. One thing, always leave the carby bowl half full of petrol. If it is full, it'll wear the fuel valve seat. If allowed to run out, the float will wear out the bowl bouncing around all day. Leave it with a puddle of petrol to float on.

jiji Xx said it all, me=71-1/2yo, I LOVE this "old" equipment. Great explanation and teaching Video ! I want to get one, move my truck out of the garage, and park the D2 in there !!

Construction jobs used to have Starting Engineers. Their job was to take an Oiler and get equipment running. At breaks, lunch, or any time equipment needed to be shut down or started, you called the Starting Engineer. Improperly done you could wreck a engine or get yourself killed if you had a transmission engaged and it fired up. High torque starters changed all that. I think Locsl 798 out of Tulsa OK still has a Oiler and Starting Engineer clasjfication.

Cool, got the same version of this only it's a D4. My Cat T model buddies ask where the starter key is, I hand them the pull rope, priceless expressions. Mine has the over head frame cable system by LeTernou.

thats a nice sounding cat. my dad used to run one of these.

Old school operation is buried with the dead..so before i die..pony engine start up..engage the diesel..circulate the oil a bit..throw on the compression..then spray the oil bath filter opening with a shot of ether..the diesel usually fires and your done!..the whole process takea no more than a few minutes..

I once asked an operator of a Bucyrus-Erie dragline what engine he preferred. He replied that he preferred Detroits over Cats because he didn't have to monkey around with Cat pony motors.

All mechanical no electronics....its a beautiful thing...

My experience with starting CATS is get the pony warm after a minute or so and simply pull the start lever and it splutters into life, Then close the valve lift. About 90 sec.

Great video! I've always wanted to know how the pony engine was engaged and disengaged, but forgot that the main engine started off with less compression. :)
