[@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!

[@justinbrownell1194]

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.

[@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!

[@CAPNMAC82]

My MYMC, back when he was a mere E7 had some sage advise. That in us all were three donkeys--one dumb, one wise, and one Jack.

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.

Great to watch you think through and diagnose a problem. I've always thought even though folks may share the same job title, don't assume they are knowledgeable or always know what they are doing. How many techniancs or mechanics care to understand or can truly understand the theory of operations of most things they work on? 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. There's nothing that can take the place of God given smarts of course but training and experience can at least get you pretty darn close. The videos you share give me a better appreciation for the state of California. You show some pretty cool places.

Sir, I'm an old maintenance supervisor from the plastics industry, its not that it caught on fire, but what caused the fire in the first place? You Sir, in my humble opinion are a dam fine mechanic, good job!

[@newjerseybill3521]

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.

I used to be a mechanic just like that. I've always found it fun to try to figure out what the problem is. I worked on pretty much anything from little Honda GX270 engines to big diesels. I work in IT now and I miss working with my hands, but I do enjoy sitting in a warm office during winter. I may start doing small side jobs in the future just for fun.

I was in hopes of seeing it loaded by the end of the video but oh well. At the 20 minute mark I could see something that looked like a crack on the quick hitch. If you would be so kind as to look at it there it might be helpful. Anyway , see you next time.

He was leaving his house as I was picking up the truck in the mornings, & would return home after I had dropped the truck off for the night.

[@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

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.

Deere’s don’t have a boost gauge and I think this tractor is too old still to have a computer plug in for live data. I believe that started on the 30 series but I might be wrong. The computer would know it so at most it could throw the stop light. Not too sure on this big ones
