Re: John Deere 440 icd advice

How would one tell if it was done correctly or not?

Re: John Deere 440 icd advice

Been a while since I have been on so I thought I would update. I have a working machine now after having the cylinder head reconditioned, starter rebuilt, all new steering clutches, and lots of other work. Just wondering where this one has had the reverser gutted and straight shaft put in its place,...

Re: John Deere 440 icd advice

Yes I did. I welded a nut to it and eventually it came out with more penetrating fluid and going back and fourth with it. I think the bolt had a slight bent to it.

I'm located in New Brunswick Canada. Updated my info

Re: John Deere 440 icd advice

After some more digging and reading through my manuals I have found the reverser has had its guts removed and straight shaft put in its place. That would explain why the reverser handle has been removed. So that narrows my slipping down to the main clutch or steering clutches. Looking in the right s...

Re: John Deere 440 icd advice

I have been looking at other older dozers around to compare undercarriages and I would say mine is in good shape. Looking in the clutch inspection covers everything looks a little wet/greasy so I'm hoping that's where all my steering and pushing problems are and not main clutch or reverser problems....

Re: John Deere 440 icd advice

So the head is cracked between each exhaust valve and injectors tubes on both cylinders. The radiator has a small crack in the top and was full of mud and grease and the water pump must have been leaking by how rough the bearings feel so I think the previous owner got it hot. There is no temp gauge ...

Re: John Deere 440 icd advice

So if I try to push too much it acts like the main clutch is slipping, the engine doesn't bog down but just stops moving and I can hear something turning. After warmed up i am getting lots of foaming coolant past the rad cap. Coolant definitly getting in the base oil. And also the engine ran away on...

Re: John Deere 440 icd advice

Picked it up for $400. Oil seems greyish like its thinned out with fuel Maybe. Going to borrow a pressure tester for the coolant side and go from there. Pull the valve cover and have a look. Steering worked good for a minute then lost effectiveness after that

Re: John Deere 440 icd advice

It will most likely be a cracked head. You should tell me where it’s at and I’ll check it out for you? Detroit’s are a very basic engine. 253 parts are getting hard to come by, the common parts with 353, 453, etc are all readily available. We used to sell a lot of Detroit engines, now maybe 1 or 2 ...

Re: John Deere 440 icd advice

Sounds like a head gasket. Had the same problem on a 450B I just bought. Had the head redone and it fixed my problem. Sounds like a cheap fixer upper. If your able to do the work yourself your just out on parts. Atleast when your done, you know what have when your finished. That is why i am on the ...

Re: John Deere 440 icd advice

I forgot to mention there was a lot of bubbles in the coolant when It was overflowing. It seems to have every indication of a bad head gasket or cracked head/block. Owner was not interested in me doing a pressure test on it. He obviously knows what it's going to prove. I think I could get it for muc...

Re: John Deere 440 icd advice

Had a chance to drive it today. Started very quick with a bump start and shot of ether. There was a little spitting from the exhaust joint but not very much at all. However, the oil turned milky again. So wondering where it was sitting for 4 or 5 months it separated then mixed again after we started...

Re: John Deere 440 icd advice

For the most part yes, not hard to take apart. No idea on the skipping. If you have to jerk it to get it to work, something is wrong. Crawler in general kind of sounds like a wreck. I hope you are up for an expensive project. Lavoy Yeah I'm getting the feeling that I am going to have more into it t...

Re: John Deere 440 icd advice

Yes, cups are bad on the cylinders. 2 stroke Detroit is by design a pressurized crankcase, but that can't push oil out the exhaust even if it wasn't. Yes, injectors need replaced possibly, and if so, they need to be set to height with the factory tool, and the rack should be set at the same time. L...
