Cat 992C Cold Start

Hey it's November 2013....what's that mean? FUCKING COLD STARTS!

[Only-one-life-]

I was told once by a cat mechanic
Put pre heat on 30 seconds
Turn over for 10 seconds so has to put diesel in to the cylinders
Then pre heat again for about a minute
This with the unburnt diesel is a huge help..
Then turn over again for maximum 30-50 seconds
Great video though
A legend of a shovel
Thank you for the effort to make this for us to view.👍🏻🇬🇧

When I was driving long haul in the 1970s, the semi used had a detent lever that would not allow for cylinder compression until released. Excellent for cold starts by letting crank get up to speed, oil flowing. On releasing, the diesel started,  began running quite well.

Being a (retired) service manager of a heavy equipment dealer, I have to agree with McGillicutty88, Auction yard equipment like that poorly treated Cat, will likely show this abuse 'down the road' so to speak. Most operators and owners will agree that you do not crank a cold engine like that for more than 30 seconds, ...rest each time for the batteries to re-bound somewhat, .and stop the diesel fuel washdown effect on those cold pistons and cylinders. Also no real need to start up this unit, unless it is going to be run at least long enough to warm up completely, especially in very cold weather as is shown in the video.
I can, however, appreciate the video effect of watching  a diesel engine come to life, ..but don't do it at that engine's expense.  Of course, this is only my opinion.

It's a big motor people. Relax, it's called routine cold starting. Sometimes I have to crank my truck with a 3406 CAT a couple times before it wants to come to life. She has almost a million miles on her here in PA and our winters get pretty nasty. No problems if you're an experienced operator. Nice videos man.

That machine looks tight for its age I love the old controls in those machines it's what I learned on I always feel right at home in those cabs great piece of equipment there awesome cold start to

I love watching these from my comfy house verses being out there coaxing frozen diesel engines back to life. 3 am show ups to get the fleet running by 6

Its a Ritchie Brothers Auction the eqiumpent sits for long periods of time in their yard.

This is a case where a bit of starting fluid would make a huge difference. All that grey exhaust smoke means that unburned fuel is soaking piston tops and especially exhaust valve stems. Many of these engines have been damaged by exhaust valves sticking in their guides after the unburned fuel on valve stems turned into varnish, when the engine warmed up. Use block and oil pan heaters, when starting in cold conditions, use enough starting fluid to make sure all cylinders are firing.

crank for thirty seconds let sit for 30 so the heat generated from the first 30 sec crank can spread through the cyclinder. try another 30 sec crank if it don't start wait another 30  sec. the third time it will fire

i was 12 years old the first time i step in a machine like this the engine sound its just nostalgic for me i love it V12 twin turbo charged diesel

[jorgekazachek]

this is a one of the best wheel loader CAT made it for really heavy working!! I remember on year 1991 I operate a model like that and the engine working around 3 month's NO STOP day and night 24/7!! just 3times per day making a break for put fuel grease check levels and full throttle I can prove this equipment is a KING no one can resist like this!! we talked about on year 1991!! I don't know today

Cranking on a starter like that is perfectly fine, done it many of times, cold weather and diesels don't mix my truck has 178 thousand miles and I crank on the starter like this to get it started sometimes, haven't replaced the starter yet

I was responsible for a fleet large diesel machines. I never let my guys use starting fluid - very easy to damage an engine that way. We used a pump spray bottle (like a Windex sprayer) with gasoline in it. Give a diesel a few whiffs while cranking and they’ll start right up. Never seen anyone else do this.

The comments about using, not using ether as a starting aid are continuing the myths. The fact is that Caterpillar has recommended the use of starting aids for many years. New, computer controlled engines have the starting aid ( read ether bomb) installed at the factory and controlled by the Electronic Control Module. The starting aid ensures that all the cylinders start firing ASAP after start up. The operator in this video, by not using the starting aid, was risking sticking valves and engine damage, particularly on the 3412. As the engine warms up and the partially burned fuel coating valve stems turned to varnish, valves stick in their guides in the open position and contact pistons. Many engines, not just Cat, are damaged in this way.

Nice when you don't own a nut or bolt in a machine you can run the starter till it cooks

[agoodneighborautorepair]

Very nice video, When I was in Canada I did remove the air filter and use a touch to heat the air that goes inside at the same time that cranks the engine, blessings.

[devindowning]

they need to start all of them up one at a time

[greggminkoff]

Question: How do you prematurely kill a starter?
Answer: That's easy. Have an inexperienced operator over crank the starter because he didn't leave the glow plugs on long enough.

Caterpillar provides oversized glow plugs for extremely cold starting. And if you can read,
they have a chart that shows you how long to leave the plugs energized. This is based upon outside temperature.

thats how i feel before the first cup of coffee

That's a very old machine. But it looks brand new. Caterpillar refurbished? The newer machines are, the easier they are to start. Personally, I wouldn't hold the starter that long. I would just give it more pre heat. Our machines (the 992's, and Compactors, at Fresh Kills Landfill) All had Ether injectors. They make for super easy starting. Just crank and push the button. The computer automatically give it the proper shot of Ether. Vroooom. That's it. (If your out of Ether, then use the manifold heater or have a mechanic change the bottle. Caterpillar does a terrific job refurbishing machines. They refurbished two 983's for us, better than new. (They were eventually replaced a new 973.) Plus I had three D6R LGP's refurbished. One came back with a extra heavy duty bottom end. The machine was like a solid steel anvil yet graded like a butter knife. I pushed out and graded millions of yards of dirt and made 10's of miles of access roads with that baby. IUOE Local 15, 38 yrs ret.
