A stall test is a load! They load it to the point the torque converter stalls out! MAX load possible.

D6c cat loss of oil pressure

steve.algren.. this thing has gotten so crazy if it were me I would go straight to the service manager and ask how much they are into you right now.
this might not go down well but your tractor is really old (even though you really like it) and it's true value is very low. now consider that it might pay you to cut bait here and stop all resuscitation attempts and turn this tractor into an organ donor. look around for a decent D6D (or just rent a tractor) which there are a lot available for around 20-25G and start over. the real fix for your tractor is going to be a new crate motor. I don't believe ziegler is going to swallow that. just some food for thought. right now your machine is the worst kind of money pit I have ever seen.

With my luck, I would end up with something worse than what I have now!
when I got my 6D it had a rash of stuff go blooey. lost exhaust gasket backing off the lowboy when it arrived, to fix that it took a reman head, new manifold, new injectors, (turbo was shot too) water pump/all bearings in the fan drive. ran about an hour and noticed radiator was pushing coolant out, new radiator went in fixed that then injector pump had some kind of bad serious disaster that required a complete rebuild ( this was a good thing, it runs extremely well now). still had trouble with trans heat so found trans pump was shot fixed that really great then final fell apart so had to fix that in the field but all good now.. (also took new rails, segments, pads) whole bunch of leaks around the torque converter that I got to spend a lot of quality time on my head reaching in there to fix those.. anyhow just pointing out that with these old tractors you are never done. If I had any work lined up for it I would do the trans, reseal/bearings the rear cross shaft and clutches, and the other final which probably looks about like the one that grenaded, but this old girl will probably just continue to be mostly yard art now. and this was a tractor that actually looked pretty good.
I wish you the best of luck, if you were closer you could come get my D and give it a workout. you would have to give it a charge of refrigerant, however..

Thanks for the offer, real kind of you. I just don't know exactly what I am going to do. I am in to this way too deep now!

Hang on Steve, It will be a classic soon. Then you will learn the next lesson. Lesson 2. Just because they are rare, it does not mean they are valuable.

Dozers are pretty much money pits, the bigger and older they are the bigger and deeper the pit. There's are reason the guys that do dozer work for a living charge what they do and stay a month or more behind. Just hope that you have enough projects to work this repair bill out of the tractor Steve. Not sure how deep you are in the machine but I'm sure 1,000 hrs or so will work it out. We put around 900 hrs on ours last year (personal use) at $125 an hr I could pretty much rebuild the dozer and still be ahead. It's not all doom and gloom.

... and lesson 3>> NOT ALL CAT DEALERS are the same..
Just because they hang a sign out front that says CAT.. doesn't make them smart enough to fix everything..

Yes, but how are you supposed to know which dealership is good at rebuilds? I just believe you have to trust a dealership. After all, as someone posted on this forum,"caterpillar mechanics can fix anything caterpillar makes ".So who are we,the average Joe, supposed to trust?
have you reached out to corporate cat and complained or inquired of this dealership and what training they have or dont have and asked if they could look into whats going on? every company has customer support on a corporate level way above the dealership level, maybe a call from corporate to the dealership may make a difference or for the least they know someone up the food chain is watching whats going on...theres more than one way to skin a cat...LOL

I guess it depends on how far away the next Cat dealer is. If an authorized Cat dealer has problems figuring it out, I don't see a problem going over their head directly to Cat corporate. Cat like most manufacturers is always telling you to use OEM parts and go to their dealers because they have all the factory training and special tooling, blah, blah, blah.

I think there's ways to talk to Cat corporate if the dealer can't figure out what is wrong. I'm sure the dealers must have to meet some kind of standards to be an authorized Cat dealer in the first place. Maybe corporate has heard of something similar since they deal with all of the Cat dealers. Maybe the dealer should be reaching out to Cat themselves if they can't figure it out? If this was a big customer having all these problems the dealer couldn't figure out Cat would for sure be involved. It shouldn't matter that's it's not a big customer and maybe the dealer is just hoping Steve goes away. He just wants his engine fixed which shouldn't be rocket science to a Cat dealer. It's not like it's a 2030 tier 16 with 42 separate computers controlling it.

Yea but one of those they could plug a `puter in and it would tell them everything that has been done to it since it left the factory and even tell them the which operator ate what for breakfast the day the problem started!

It would probably cost 20K just to hook the computer up to read it and have to be done by a Cat dealer. It's not like it's a rare engine in a rare application is why it's so puzzling why know one can figure out what's wrong.

Anybody else have the book "Beer and Diesel Fuel" in their library? Its a decent read about a Cat factory service rep that traveled to multiple countries to solve and sometimes offer re-engineering advice to the factory when the local dealer was stumped. Its a entertaining book to read while educating us about various Cat machine issues and how they were solved.
