Thought I would start a new thread for all to view and learn from.
Got the muffer and muffler bracket off for a better view. Check out the arrow below the hole?? more failure in case?
Went ahead and drained the oil. Hope I don't find too much metal.
Tomarrow I will start unbuckling everything so i can drop the tranny lower. Then we'll peer into the abyss.....
later

YOIKS!! what a drag. three posts on the front page regarding your transmission. from to to .

That looks like the vehicle in "Journey to the Center of the Earth"comin' outta der.
Hell, a little fibreglass cloth, some JB weld and 200 MPH race tape and you'll be back on the road.
Haha that's what happened to my last transmission! Sorry i'm not laughing at you, i'm just glas i wasn't the only one. I just broke my third. The first a washer/spacer shreaded apart and fot stuck in the pinion and the second looked like yours and the third makes some really nasty sounds. Good luck with that. What are you gonna do to fix that?
you should be able to just replace the back plate.
you can do that without dropping the tranny.
that is, IF the internals check out OK otherwise ...

I don't know what that is (arrow), but I don't think it's related. probably just a casting defect that the factory considered acceptable. No case/cover defect could have cause this, it was definitely a failure from the inside out.
Uh, guys, that is the speedo drive gear that _DRILLED_ its way through the rear case. Either the pinion bearing failed or the large nut at the end of the pinion shaft was not tightented, came loose and machined a hole in the case.
In either case, the rear cover is hosed. Get the rear cover from your tailshift tranny and install. Or better yet, do a sideshift conversion on your old tranny and take the best parts from the two.
If the bearing is OK, you will still need to replace the big nut/worm drive. It takes a 30mm socket.

James, hoped you would chime in.
It will be a couple of days before I am inside the tranny to inspect. In the meantime, are there any clues (from how the car was behaving) to describe the two failure scenerios you described?
Also, regarding using the tailshifter end cover, I core swapped the whole thing so....not an option. But I will be contacting the seller to "sort this out"
thx
Not sure if this is worth noting. This pic is the bottom of my drip pan after draining the tranny last nite.
No big chucks of metal yet, but lots of brass fragments (from the bolt). At some point, I will need to learn how to do a proper flush of the tranny. Can this be done with the tranny in the car?

If you want some help.. I have all of the tools and lots of experience with 914 transmissions. Plus I live in Hurst, so it's not that far to McKinney...
The rear cover on your transmission is hosed. But if the internal parts are good, we can put a new cover on it.
Let me know if you need some help.
Made some progress today. Got everything unbuckled and lowered the tranny to a workable level.
Rear cover is being stubborn, but was able to remove the speedo drive (see below). Looks none worse for the wear (to my untrained eyes). Important to note that with the drive removed, I can see that the 30mm bolt is completely seperated from the pinion. So hopefully the worm/bolt backed off the pinion verses the pinion bearing failing.
Thanks to Clay Perrine for the great phone support and keeping me out of the deep end. This club continues to prove that it is made up of super folks.

Does anyone have a tip for removing the rear cover. I have removed all the bolts. I used a rubber hammer to lightly bang on the ears to break the seal between the end cover and the intermediate plate, but I can't get the end cover to let go.
Basically, how can I put force on the end plate without causing the intermediate plate to separate from the main case? Prying apart would be easy, but I am afraid of damaging the mating surface on the intermediate plate.
Anyone??
Maybe a "little" more force. DO NOT USE GORILLA STRENGTH.
Most likely, the re-assembler used a non-drying gasket sealer to seal the cover. You could try prying with a long screwdriver, up the speedo drive hole. But I really thing you just need to keep working the cover. Make sure you really do have all the nuts off, but that is kinda obvious.

Spoke to the seller, he is waiting to hear what all is damaged.
Ok, got the end cover off. Now for the pics. First is the source of the hole - worm drive.

Now the end cover. Note the scoring in addition to the hole. This is from the Guide Sleeve.

Finally the back in of the tranny. Note the thrush washer apparently moved when the cover was taken off. Also, the Guide Sleeve was close to falling out once the rear cover was removed. Is sitting kind of loose in this pic.
Clay, PM is on the way.

The washer is part of reverse and moves when you have the end cover off. You have to "hold" it in place with a good slathering of grease, along with greasing the reverse shaft with grease to hold all of that in place.
Yes, the item the rev/1st slider rides on is held in place with the large bolt. Hmmmm. I might have one laying around here...Too bad I didn't know 3 weeks ago, cause I dumped multiple cases and tailshift covers.
I am sorry, is there a bolt missing? I don't follow
You keep mentioning tailshift covers, but this is a sideshift tranny. Understand that they are interchangable, but is the tailshift cover better?
The calvary arrived today. Clay Perrine arrived on the scene to help inspect the damage. All things considered, looks like i may have dodged a bullet. Damage seems limited to the bolt/worm drive and rear cover.
Will hopefully have parts, gaskets, etc by late tomarrow. Then wind her up again.
Went over and took a look at the tranny last night. He needs a new retainer bolt and a cover. He has one coming from the seller but its going to be a few weeks before it gets here. I was planning on taking the parts off a spare side shift tranny at my house and taking them over tonight, but I got reminded of a prior commitment for tonight. So it will have to wait until thursday. Then we can get him back on the road.
Mega thanks to Clay Perrine. I am back on the road!
Dodged a bullet as I only needed a replacement back cover and pinion bolt. Oh yeah, had to tap the threads in the pinion shaft as they got buggered up when the bolt drilled through the back cover.
New parts are on loan from Clay till I can get replacements from the seller. Great to find such a great 914 community.
Great news! Whew!
In order to keep dodging bullets I'd flush tranny fluid through that thing more often than usual. There is without a doubt a bunch of tiny filings of brass, steel, and mag floating around in there!
Completely agree. I was going to change oil in 500 miles.
Just an update for everyone. We put John's car back together Wed. night. We had to use a 12x1.5 tap in the end of the pinion shaft to get the bolt to go in, as it had buggered up the threads. I am really embarassed, but when we reassembled the rear of the tranny, I put the needle bearing on the wrong end of the reverse idler gear. So the gear hit the bearing retainer plate.
We finished up at about 8:30 at night, and I had an hour drive back home. John pulled it apart Thursday morning, and put theneedle bearing on the correct end of the reverse idler and reassembled.
He called me and told me that he is back on the road again!!!
Good for you John. Those were some fugly pictures.
Gotta say though, big honkin' round of applause and shots for Clay. What agreat guy to drive an hour to bail out a fellow teener. Proud to be part of a group of people like that.
