Hi Warren I'm a John Deere Tec in firebaugh CA Great videos man . Great find on the inner cooler. When you pull that engine out you dont have to take the good off.You can stand it straight up and tie a rope from the top to the bottom of the tractor. Them hoods are a pain in the ass getting them off and on. Keep up the great work.

[@ebeneezerspooge3011]

Awesome stuff, glad you mentioned it was going to get rebuilt, when I was still learning to be an ag mechanic, was called out to a farmer with a Massey Ferguson wheeled excavator (UK), wouldnt start. Took the air filter out and it was all melted, they'd been burning brush and using it to top then bonfire up, no compression. Farmer was in a hurry to get it backup and running, took the sump off, rods and pistons out, large screw driver, hammered the liners out, new ones in from the bottom, new pistons and rings, serious bush fix!

[@justinbrownell1194]

Warren, I had this exact same problem this spring on a 9620 wheel tractor. Customer had problem for 3 years. Customer and other dealer had Put two turbos on it, one manifold. Other mechanics never once checked components over. I went out to unit and checked few things on it. Checked boost pressure zero. Looked over components and found cooler split just the same way. Hydraulic tank was melted as well. Installed new cooler and engine still seemed to smoke and knock. Found that aluminum plug had started leaking rail pressure right into the intake manifold. Drilled and tapped cylinder head was good to go. Thanks for the videos!

Hey Warren up here in Canada those intercoolers are like 7600 bucks. My customer had found a cheaper one down in the states, aftermarket actually. If your interested I can find that information out for you. Had to extend inlet side pipe of cooler for aftermarket cooler to fit but works great.

In this time where people are supposedly smarter it's always great to see someone who really understands the ins and outs of their chosen field.

If you are talking about the soot on the right side of the engine, that isn't from a fire. The exhaust gas temperatures where running high for a long time warping and cracking the exhaust manifold. This caused exhaust leaks at the manifold to head joints, and at the cracks.

Hey Warren, the Milwaukee tool warranty sucks and it is very hard to get things repaired or replaced. I have a Milwaukee store and service center near me and I have had terrible service. If you are having issues with batteries I have a easy solution as long as your battery case is not all broken. I buy brand new batteries and take them apart removing the guts and I place the guts from my old batteries in the new batteries cases and then I return them for a refund.

Sorry to be thick Warren, wouldn't a cracked intercooler result in boost pressure reduction and lower fuelling. I can't quite see how this alone would cook the thing.

Not sure why you ran that turbo oil feed right to sump. Wouldn't that cause a major loss of oil supply to the rest of the engine, without the restriction of the turbocharger bearings? I've run a few diesels without the turbo, but always capped the oil supply that would normally feed the turbo. Just wondering.

[@grego3150]

I would check the reading from the boost pressure sensor has not stuck reading full boost with low boost pressure the ecm should have adjusted the fuelling down in line with boost pressure......so its fuelling for high boost with low boost thats probably why its chucking a ton of smoke now
