This video is proof that the majority of people out there don't know how to properly use a starting engine and why so many are completely trashed when I find them... The procedure for starting this tractor properly in a hurry is 4 min.... 6 done correctly at normal speed ... I had a mint condition D4-7u and it takes 3-5 min to start summer time or winter, longer in the winter... That starting engine is to provide a warm start for the Diesel... Even in the summer open the compression release and leave the throttle off and crank it for a good couple min before you close the compression release to allow the engine to build heat in the cylinder walls. Once there's some heat in the pistons and sleeves open the throttle and itl pop off almost instantly. Shut the gas off on the pony and let it run out of gas in the carb, by the time the pony runs dry the engine will be evened out and running smoothly by then and ready to finish warming up then take off. This guy here dry starts the diesel and loads it up with unnecessary fuel then rips out before the pony shuts completely off. Already warm or not that's hard on internal components.
I ran an 8-H on a dam job and every morning I'd start the pony at idle and let it turn the diesel over with the compression released, fuel off. SLOW! I'd drink a cup of coffee then open up the pony and hit the compression and open the throttle and start chuffing. Never had a problem.
@@chimneysarecool2330 You must not be an equipment operator. There's no reason to treat the equipment that way. You need to care for it so it can last a long time job after job. It's your livelihood. If you were the owner of that dozer would you want ragged on?
Breakages cost time and lots of money.. Been gentle to this big iron pays huge dividends to its owners,but gives the operator a great sense of achievement in looking after there well being
@User-ww3rc you say its repairable but parts for theese donkey/pony engines are getting very scarce I have a friend who's trying to rebuild his d9d even fire donkey engine as the crank has about 5+mm lift due to being abused and its proving extremely difficult at the moment as nobody stocks parts for them anymore
Them pony motors were the most abused engines ever. No warm-up, right to full throttle full load and when the main catches they were over spun. Last but not least shut off cold. And treated this way for decades with no maintenance. It's a wonder they lasted a minute
Not to mention, the pony is splash lube motor, no oil pump, and main bearings had a small oil hole on top that oil had to run down then start to lude. Worst thing you can do is what you just seen
The number of operators who dont know the correct starting procedure on Cat equitment amazes me as an ex operator we would have been sacked on the spot if we were caught starting a D8 or D9 like that
No hablo inglés pero más o menos comprendo una que otra palabra,según yo,el título del vídeo es sobre el encendido en frío de un motor Caterpillar , corrijanme por favor. El vídeo dura solo 1.45 min, y en ese tiempo tan corto encendió el motor pony ,el motor de la máquina y se movió el equipo a trabajar, o una de dos, ese motor no estaba frio, o el operador no conoce los protocolos para encender una máquina antigua, así como su temperatura, entonces no es profesional a mi parecer,ya que también mantiene los pies sobre el pedal de freno al estar en movimiento el tractor, ya que solo debe aplicarse en caso de ser necesario y no mantenerlo constantemente sobre el pedal. saludos.
Dicen que el pony motor es arancado y sin dejarlo calentar un poco y ni un minuto....se toma la carga de arancar el grande!!!!.. despues se lo para sin otra manera... todo eso con poco mantenimiento!!!!...
This is NOT the way to start a Cat with a petrol pony motor. This "operator" did just about everything wrong. Correct method is to let the petrol engine run for a minute or two to warm up then to engage the diesel engine with the (diesel engine) throttle off and the diesel engine decompression lever engaged. Allow the diesel engine to spin for a couple of minutes on decompression until the oil pressure is right up and you have good fuel pressure. Only then should the decompression lever be flicked over (still with the diesel fuel off). The length of time that you allow the diesel engine to turn over like this depends on the ambient temperature that the machine is being operated in; if it's quite warm then you can give it some throttle to start it almost immediately. However, if the ground is frozen over then you need to let it spin over for a couple of minutes before giving it some fuel to start (allows the air in the combustion chambers to warm up a bit). I was shown by the best and it always worked for me, from the heat of Far North NZ to the freezing cold of Antarctica.
Correct, but er close compression until you see oil pressure gauge indicate max pressure; else your main engine dry starts momentarily. This is why newer models have electric oil pressure overide.
I'd almost guarantee that Cat wasn't cold, but that operator sure is... hope it still had some oil up on the cylinder walls. This is the exact reason why you see so many pony motors torn up on these older machines.🙄
Cold start the wrong way. This is about as amateur as you'll ever see. Don't ever start like this. First let the pilot motor warm up, then engage the main engine with fuel off and with decompression leaver in the on position, (no compensation) Let main engine oil pressure build up, circulation is critical. Engage compression, check coolant for bubbles (if bubbles, you have a blown head gasket) secure radiator cap, check main engine oil level. Turn the fuel on and wait for all cylinders to fire and disengage pilot motor, shut pilot motor off. Idle main engine until oil temp and water temp starts to rise, then increase RPM so as not to glaze bore through prolonged idle. Winter operation l would stand behind blade to get warm and its a good indicator that the coolent is warming up. (Reving a big diesel on a cold start up can snap the Crank.) Check oil level while engine is warn and running. Your Cat engine will last as long as you when you feed it clean air, clean fuel and regularly change with good quality, correct oils and filters. Never put it to work cold.

jeez if it starts it starts but if it breaks down its his fault stop making a big deal about it!!!!!!!!!

Nah just some operaters are abusing them while others treating those motors the correct way
Not to mention, the pony is splash lube motor, no oil pump, and main bearings had a small oil hole on top that oil had to run down then start to lude. Worst thing you can do is what you just seen
The total run time of a pony is probably less then 40 hrs.
That's why they lasted
Man I love it ,those old caterpillar diesel engines
Thanks for letting the pony motor warm up Tard!!
Pony motor What about the main engine starting at high revs without using pony to build oil pressure first?
The hard life of a pony motor.
That looks like Gary Mace!>!>
Nice and a Thumbs Up Liked !
Damn guy ,you're rough on the equipment.
I wouldn’t let that guy anywhere near my equipment!
Used to run a D8 14 A stick with a pony.
Let the poor little pony run for more than 10 seconds before you engage the starter
with the compression release shut
The transmission safety lever should be up whenever the operator gets off the seat for any reason.
If that was my equipment, one start like that and that "operator" would be unemployed!
I agree!!!!!!!!!!!!!!!!!lazy
Looked like he forgot to open the compression release, and had decelerator ever set at to high idle for cold start.
The number of operators who dont know the correct starting procedure on Cat equitment amazes me as an ex operator we would have been sacked on the spot if we were caught starting a D8 or D9 like that
Soon be some fit spots on those carrier rollers tracks need shovelling out
What a DURP, are you trying to kill my equipment!
jeez if it starts it starts but if it breaks down its his fault stop making a big deal about it!!!!!!!!!
Muita maquina
Big dozer
Ну хоть здесь с пускача завели, ато я думал они совсем там загнили.
Exactamente Bernardino el operador no conoce el proto de arranque de ésos motores o ya estaba caliente y solo se bajó a cagar 3 libras
This was so painful to watch. That was done all wrong.

Didn’t look like it was that cold
Dam. Let the poor thing warm up.
Know dought , leter warm up more than that
For startin deisels cold, they will start and run on w-d 40 . When you dont want to use ether.
jeez if it starts it starts but if it breaks down its his fault stop making a big deal about it!!!!!!!!!
@@chimneysarecool2330 With the number of times you have repeated your response I'm starting to think you were the jackass on the dozer

That wasn't a cold start lol.

I have never seen one with a fuel pressure gauge and oil pressure usually builds up after 5 seconds
Douglas Oakley smaller cats have fuel pressure gauges not too sure about bigger ones
Correct, but er close compression until you see oil pressure gauge indicate max pressure; else your main engine dry starts momentarily. This is why newer models have electric oil pressure overide.
@@charlienorton2337 are you talking about newer or older machines. I have been on mostly newer cat stuff from d3 to d8 and I never have seen a gauge!?
Douglas Oakley oh yeah I’m talking old machines
I'd almost guarantee that Cat wasn't cold, but that operator sure is... hope it still had some oil up on the cylinder walls. This is the exact reason why you see so many pony motors torn up on these older machines.🙄
jeez if it starts it starts but if it breaks down its his fault stop making a big deal about it!!!!!!!!!
@@chimneysarecool2330 So you keep saying ...
A skilled operator nicely works a big machine. D9 is our longing bulldozer. Thank you from Japan.
Cold start the wrong way.
This is about as amateur as you'll ever see.
Don't ever start like this.
First let the pilot motor warm up, then engage the main engine with fuel off and with decompression leaver in the on position, (no compensation)
Let main engine oil pressure build up, circulation is critical.
Engage compression, check coolant for bubbles (if bubbles, you have a blown head gasket) secure radiator cap, check main engine oil level.
Turn the fuel on and wait for all cylinders to fire and disengage pilot motor, shut pilot motor off.
Idle main engine until oil temp and water temp starts to rise, then increase RPM so as not to glaze bore through prolonged idle.
Winter operation l would stand behind blade to get warm and its a good indicator that the coolent is warming up.
(Reving a big diesel on a cold start up can snap the Crank.)
Check oil level while engine is warn and running.
Your Cat engine will last as long as you when you feed it clean air, clean fuel and regularly change with good quality, correct oils and filters.
Never put it to work cold.

That poor pony motor..No time to warm up straight to maximum revs cold..maximum torque..then shut down..Seriously...??
That don't look very cold........

Not very good at this is he?
