View Full Version : D2 starts too quick?

I'm still getting acquainted with my D2, never having had one before.
I read much about the starting procedure with my pony motor etc. and it all works fine until.
Everything I read said it might take minutes for my main to get warn enough to run on it's own.
But my main will start in cold weather even after the pony spins it for as little as 15-30 seconds.
Am I doing something wrong or dangerous? Or should i just be happy?
My unit has 2400 hours on it and sat in a shop idle for the last 30 years.
Thanks

I think I'd be happy. What do you call Cold weather? I'm alittle green also but have a D6-9U that starts very well at 30 degrees. I can just let pony rolling main engine long enough for me to check oil pressure and then get myself back into position and start main engine. Fire in the hole!! Puts smile on my face every time.

Have fun, be carefull,

Be thankful that you have an engine with very low hours on it !
Crank over the diesel engine with the compression lever in the start position ,so the lever is pushing the intake valves open ,and releasing the compression .Watch the diesel engine oil pressure gauge ,and turn compression on when you see that the oil pressure is up to the maxium ,and let her run and purr like a kitten !

You are leaving the fuel off until you want it to start aren't you?

Yes, what is "cold weather"?

My Two Cents is that the Manuals all say to wait for this to happen and that to happen.
I do AGREE that the longer it spins, the more the oil gets pumped around thus building pressure, the main heats up more due to warmer coolant and manifolds while the cylinders build heat.
BUT!
What happens to all those requirements when a guy buys one with a Factory electric start or removes the Pony to install an electric start?
SO
In conclusion I would figure if it starts up with in 30 seconds, then AWESOME!

start according to the manual, sounds like your leaving the fuel and compression on. diesel must spin (not running) for awhile to get oil pressure up and lubing, THIS IS VERY IMPORTANT. again start according to the manual. good luck.

I recall previous comment here that each machine is different, and they will behave differently over time too. I saw a D2 that had not been started from many months start easily. The pony took 2 pulls, and away it went. The starter clutch was engaged, main engine spun over for a matter of seconds while the oil pressure was checked. Thumbs up:thumb:, decomp in and away she went. Total time? About 20 seconds from pilot revving to main running,

But, the same machine at my place did not behave as well, taking ages to get the pilot going, and a lot longer than before to start the main! Figure that one if you can. My D4 is different again and takes quite a lot longer than the D2 to get the main firing nicely even though the motor is reconditioned.

Clearly there are many factors affecting starting times - engine condition, timing, fuel quality, filter state/fuel pressure, ambient temp, injector efficiency, operator technique and so on.

So enjoy the regular easy starts while you can:flypig:

I always found it easier to get a clean start by leaving the throttle closed and going to full compression as soon as the oil pressure built up, then wait until the engine starts to 'beat' before opening the throttle, then they will fire straight up. Running on full compression is far more effective in warming the cylinders then the pony exhaust going through the inlet manifold.

Thanks for all the feedback; just wanted to be sure I wasn't harming anything.
Cold weather start here is Central Ca. is 30 degrees.
Yes, I do leave the throttle closed and the compresseion release on until I see oil pressure.
After applying compression, I then wait to see some black puffs from the main stack and then I think what i hear "Catsilver" calls the engine "start to beat" and then I crack the throttle.
She usually takes off in about 10 more seconds.
Thanks again for all the operating input.

Sweet D-2

I presently own two D-2s, the one I got from Mike Mc, out in the thriving community of Rosedale, starts very much like yours. The other one takes a little longer, and only wants to run after the pinion kicks out.

Must be the colder weather up north here in Visalia!! lol

Soapy, I had a 212 grader with the D311 engine that acted like yours. I learned to listen to it and the pony motor and disengage the pinion clutch to let it speed up and kick the pinion out. If I disengaged too soon, it would die out, but usually it would immediately speed up.

The engine had good power and would lug like nothing I'd ever seen before, but it was far from new.

I was feeling a little wiped out from the cold weather, and long stressful days at work. Went to the home farm to visit with my Mom last Saturday, and got into my head I wanted to hear the D2 fire up. It was cold, about 8 degF (I know not King of Obsolete cold :lol:). Checked fluids, pulled decompressor lever, turn gas on to the pony. Hit the starter and after a couple of minutes, pony lit off. I gave it a couple of minute and engaged main engine. Turned about 45 seconds to a minute with compression off, good oil and fuel pressure. Added compression, fuel off for about 90 seconds, and cracked fuel, got a couple of pops but not ready to fire off. Closed fuel and cranked for another 1 minute, and tried again. Main fired with a couple of misses and settled right down. Since it was cold I wanted to let her run for a bit, I always hate to start an engine and then shut right down. I never get bored being around running machines, and it sure changes my mood when I'm down. Everone at work kids me about my cell phone ring tone, it's my D2 running that I recorded, no one else has that! It sure generates comments when it goes off in the middle of a meeting. Spent about 30 minutes to fire her up, run, then shut down. That 30 minutes was just what I needed, completely changed my mood. I only wish we had enough snow that the snow banks needed to be pushed back.

Tim,

You don't need to see a shrink, when you have Cat therapy!!! lol

Mate, the only thing keeping me sane at the moment is the D4 30A and D2 in the shed. What with greedy relatives stealing from the old man's estate, crooked lawyers, lunatic bosses at work and the current drought and bush fire threats.....well, it's the hours with those Cats that keep me from going nuts! Best things I ever bought:lol:

Hi, Folks.
An owner complaining that his pony-start Cat starts TOO fast? Now THAT is a first. If it has oil pressure and wants to run, why in God's name would you NOT be happy that it wants to start quickly?

Just my 0.02. But what would I know after a mere 50+ years of playing with'em?

At a rate of 3 megawatts each, I worked 14 hour days to burn around $40,000 worth of Diesel Fuel for Witness tests.
This weekend the last thing I want to hear run is a Diesel!
FYI
These will start and take load in 7 seconds!
