A REALLY broken HMS trans... (pics)

Here is my original post about the trans trouble:

Now firstly this is not meant to bash terry. I have been in contact with him and he has been very accomodating and everything between me and him is taken care of. These pictures are simply being posted, because...well this trans is really F'd up, and it is really kind of interesting.

In any case you can read the symptoms in the other post...I already have another transmission so I decide to take this one apart. I took off the bellhousing and basically everything fell out.

So here it is:

Wow, Thats a TH prepped trans? what happend to it.... not knocking anyone just curious

I should say this, even tho it doesn't matter due to the nature of the failure. But it was a budget rebuild, no LSD, that is a stocker diff you see in the pics. Still looks pretty good tho.

Well...stock diff...key words right there.

But otherwise, how the hell do you drive??

It's my understanding...and I'm no expert. But I have seen blown diffs, and the teeth on this one still look great. It is the bearings that failed. Faulty part or not pressed on properly or something else.

Looks like deer poop in his tranny!

Maybe this weekend I can come down and offer my expertise.

Deer poop > Ford Honey

C'mon down I'm sure I'll be puttin it back together all weekend. Thanks for the clutch alignment tool btw.

def a bearing crapping the bed, followed by subsequent carnage. that sucks! but it does happen.

I'll wait for Terry to chime in, but it looks like the bearing damage caused other issues ... now, what caused the bearing damage? #1 cause of bearing damage in engine/transmission/turbo/anything that uses a bearing is lack of lubrication ... now what caused that? see where I'm going with this? Good luck!

you obviously didnt have your tierods and balljoints off...

I've been doin this for 30 years...

Something I forgot to mention:

This was NOT just rebuilt recently, it was about 1.5 years ago. This trans had 14,000 miles of trouble free operation and then this suddenly happened.

Why? Looks like the differential carrier bearings went out, has NOT A THING to do with the differential being stock!

If the bearings went out first it would have to do with Materiel Failure caused by any number of reasons.

exactly what i said. u must not of understood.

Just an FYI for everyone:

The trans will be going back to terry for investigation to see what really went wrong. This in no way means he is responsible for anything, it could easily be faulty parts from ford or a number of other things. We will know more once I can get it all out there. Let's not jump to any conclusions.

That is good. It will be really hard to tell what caused those parts to start failing so I wouldn't even try to pin down a exact cause of events.
I mean I know you can tell what failed and in some cases what led to what, but you won't know if it was just a faulty bearing roller/race versus some other part that broke and started causing abnormal wear that led to this.

Unless of course you say it was redline fluid. Then we'll all know what the verdict will be irregardless. BTW, it doesn't look like the fluid was failing to get into those areas, just that something was failing and the material was ginding away.
I would like to point out something stated before that as metal grinds away it will form a paste with the available lubricant and then cause a blockage preventing additional lubrication; even if the lubricant wasn't originally at fault.

BTW, what kind of lube did you have in there anyway?

Mobile 1 ATF + XL7 Friction Modifier...seemed to be the most recommended fluid at the time.

Inner ring raceway fatigue. From what I can see in the pictures.

Usual causes for this failure:
Contaminated Lube
Insufficient Lube
Improper Installation (too much or too little clearance/preload)
Poor heat treat on raceway (too soft).

I had this in my trans when it broke, but totally diff circumstances. I may be going out on a limb here and say that I think this cocktail helped wear my synchros out faster. I had the stuff in for less than 3 months and then my 3rd gear started to say FU. At 5 months or so my shift tower broke...unrelated.

Any thoughts on this...my claim is without lubelogical expertise sooo...grain of salt.

I've had mine in for quite a bit longer than that, and the tranny shifts great.

M1 plus 2 oz of cocktail for about 80k. LOL! Trans looked great when it was opened up. I think I only had one sync replaced for peace of mind.

could definately be coincidence, but I had the EXACT thing happen to me. 3rd gear syncro went out within 3 months of adding the FM and M1 coctail. I installed the fluid at about 80k miles.
