Starting with fuel on before there’s enough heat in the cylinders is hard on the engine. Fuel dilutes the lube oil, cools the compression and causes detonation as the fuel starts to combust too late in the timing. Far better to crank with no fuel and try to introduce fuel periodically to see if it’s ready to run.

You're going to want to change the oil after all that fuel dilution! Opening up the valve clearances will help increase compression pressures during start. that would help, as well. It will reduce valve overlap.
Once it warms up in operation , the Excess fuel will evaporate off . Valve OVERLAP doesn't affect Compression . It DOES affect transitional breathing .
Here,s an idea. Put some glowplug harnesses on it & connect them to a switch & battery. Old precom cat engines need them working to start. Or another alternative is to roll up some news paper & light it & hold it in the air intake & let it suck in some fire. Ive done it plenty of times & the ash it sucks in wont hurt anyrhing.
low compression takes longer to build heat in the cylinders. You're getting to autoignition temperatures but the cold in the cylinders takes a long time to offset.
This caind of the engine is a same like on CAT D9L I operate this bulldozer the engine had more 76.000hors work and still runs without problems it's a really fucking good this engine 👌 👏
Diesel engines do not get “flooded” like gasoline engines can. The white smoke while cranking is unburned fuel resulting from lack of compression heat in the cylinders. One mistake people commonly make when cold starting a diesel is introducing fuel too soon. The incoming fuel has a cooling effect that makes it more difficult to start. It is better to crank a cold engine without introducing fuel until it has had time to develop some heat in the cylinders from compression. Then, fuel can be admitted and the engine should start right up. This is the reason that “pony motor start” was invented. It allows the engine to crank for several minutes without fuel so it can warm up sufficiently so when fuel is added it can start. Cranking a diesel for extended periods with fuel and failure to start can damage the engine by washing lubricating oil off cylinder walls. It is also hard on pistons, rids and bearings, because the governor is feeding full fuel continuously when one or more cylinders fire causing excessive pressures and diesel knock.
@@dondubray4253 yes drilled conrods to cool the underside of the piston, lubricate the little end, and cylinder walls under the oil control rings. Oil also is trapped in the cross hatch pattern on the bore above the oil control rings, and this is the oil I'm referring to. Having the amount of raw fuel in the combustion chamber that these people did washes this entrained lubricant off the bore and much of this fuel also ends up in the sump potentially diluting the lubricating oil. As others have said, shut off the fuel, and spin it over to create some heat in the combustion chambers from compression, and then introduce the fuel. The knocking you can here when that engine is first firing, is combustion happening earlier on the compression stroke due to excess fuel in the combustion chambers and at a minimum this can crack piston rings and blow head gaskets

Just imagine all that raw fuel scraping down the cylinders and going in the oil pan . There's got to be a better way.....No glow plugs??? Valve clearance too wide?? Doesn't look that cold. Kid standing around in shorts. You single handedly put the earth in global warming.
Well to start whit my before the club got there we spun the engine up but did not start it and that’s what flooded it and we start it like a D2 whit letting the engine turn over whit comperson to build up heat and then open the fuel.
There's a D2 Caterpillar with a rear pully attachment that is starting the engine. Check out squatch253 for a detailed sequence on starting a D2 dozer. I do the same on my D4 Caterpillar.
It is over fueled, but if this were almost any other internal combustion engine we would say it is flooded. The combustion chamber is cold or the compression is too low, either way not enough heat is being generated in the compression stroke to properly fire the cylinders. As others have stated it would have been best to continue turning the engine over without fuel to generate heat as the fuel is only quenching the heat needed to initiate combustion. More modern units use a glow plug or higher compression and a high torque starter to generate the needed heat. This D397 uses no glow-plugs but does use a pre-combustion chamber which can make starting it harder than in a direct injection engine. If this chamber is cracked you can have your compression gasses going into the cooling system causing poor starting as shown here. From what I saw in the video the cooling system on this unit is not operational but instead in a temporary fill and drain setup, and a very leaky one at that, further supporting my theory of cracked pre-chambers. Some commenter mentioned a rain hat for the exhaust to keep rain out of the engine. This water in the exhaust could also be from cracked pre-chambers leaking water into the exhaust runner. Nice engine but it's mostly a show piece sitting under that shed. Pre- combustion chambers are readily available for the unit if they were needed.
@@btwbrand I paused then scrolled the video to zoom in on the heads….this engine does have glow plugs, you can see the terminals where the wires are supposed to be connected. It’s just not wired up.

The best comment yet on this
Run for longer under compression / no fuel to heat it up more before turning on fuel. Adding fuel prematurely cools the compression charge
Good idea but we trend the engine over a little before the people came
