Why do these heads always crack, poor design, poor castings??? do every single one crack? was their a later improved head? Every 45d you hear of always seems to have had the head repaired

I would say its from what they melted down to poor the blocks and heads. The 45 diesel I had the block cracked.

They can not take being over heated. D-19D and D-17D are the same. They will give very little trouble until you get em too HOt!

I have one head downstairs that is welded up, other one is very nice. Heat can be pretty destructive. These engines could take alot of abuse, but there is a limit.

The latest heads with the waterpump on the block used smaller nozzle holders and a little smaller valves so that there was more meat on the heads . A lot people did not let the engine cool down like they was suppose to do .

You might call Sandy Lake. I've heard that there are new head castings available, don't know for sure though.

When we restored our 45D the head and block were cracked. We luckily found good replacements. One thing you could do to help keep the engine cool is put a 5 blade fan from a 170/175? on. We did that with ours and it never gets warmer than mid-green range on the temp. gauge. And that is plowing or using a subsoiler in very hard ground.

the very worst mistake you could do to the 45-d is not let it cool down after really working it.we never shut ours down at dinner time.it would idle till we went to use it.at the end of the day it was usually cooled down by the time you put it in the shed.it needed a long time water flow for cooling .

I agree with Lester, almost all of the old diesels had head cracking problems, but back in the day when you had a gas tractor when they got to the end of the field they turned the key off, which is a big no no with a diesel. People like my grandpa were so frugal (cheap) they didnt want to burn another penny worth of gasoline, or diesel so they shut them off after a hard labor, rather than allowing them to cool, which really meant that the whole engine became one constant temp before shutting down, rather than letting the head, which is always hotter and higher, so the heat rose to a hot object anyways the difference in the temps combined with castings that werent of todays standards and they cracked. My friend said years ago when they plowed with the old Minnie moe diesels if you shut them off to quick you could hear the head crack.Another reason you always seen the older diesel trucks sitting idling at a truck stop, for no apparent reason, it was just to let them cool .

The radiator on a WD-45D hold 17qts the same as a D-19D and 1qt. more than a D-17D. If you run hot it is for some other reason. I have a late C=II turbo262 in my WD-45 D and it is turned up and I pull 416s with it in heavy ground and it does not run hot.

They are known for being able to repair cracked cast iron heads.

Not all cracks are fatal. Cracks will appear in most prechamber style heads; especially around the prechamber area. Olivers have the same style prechamber, they crack as well. But seldom are they fatal. I would say that you might do more damage trying to get rid of every crack that appears than leaving them alone. If you pressure test them and they do not leak, they are OK.Cracks that go all the way to the valve seats are not OK.

IMO, the heads had too much thickness in some areas. This allowed for a lot of needed exspansion in some areas and minor in others. This condition only can occur with the inducement of alot of heat, so it's associated with an overheating problem. I've worked my 17 too hard and it never lacked cooling capacity unless I was mowing and it became blocked. The cooling system could also be a little weak in how the water is circulated through the hot spots in the head, hence the reason for the water pump being moved on late model 262's.
It does serve a need to cool it down. Though letting it idle may turn the fan and water pump impeller turn so slow it in some cases may hold more heat in rearward areas of the engine. Again IMO, allowing the engine to run at a mid idle speed but not under load will create lower BTU's while still providing good water flow is the better practice.

This problemn was not unique to the Buda motors. Case and IH also had problems that occurred from not letting the tractors cool down after use. A Case mechanic in my town tells the story of hired-hands running the Case tractors and shutting them off immediately at quitting time without a cool-down. He installed shut-off switches that let the motors run five minutes before they would stop and the problem was solved.

I was lucky enough to find a NOS head for a D19D and a NOS AC engine kit for a D19D. Mine runs fine, but I am sure at some point down the road I will want to rebuilt it. I will vouch for Midwest Cylinder Head in Nevada Iowa. they fixed a 45D engine of a friend of mine and he has never had any problems. They also fixed the block on my WD45 Distillate, and it is good as new.

Yeah I have a couple of heads, but with two D17 and two D19 diesels I'm afraid I might need them someday.

I have a parts 45 diesel in my barn but it is Lesters he is my uncle. The head has not been took off to see if its good but if there is enough interest maybe we would check it the motor is complete. The injector pump looks like it has had a new head at one time or another. I think he would sell some parts if you ask him, we don't mess with them we use 262 's in place of them. |
