Transmission shaft play

I grabbed the ouput shaft of the transmission at the U-joint. There is some definite up and down movement with attendent small clunking noises.

I also found that the bell housing internals are covered in oily grime and the clutch is slipping. I'm planning to drop the tranny tomorrow.

Is the wiggle problem trying to tell me something expensive? I think I am least looking at a pressure plate.

Thanks!

Evan

Evan, Could it be just a bad Bushing or Bearing?

Time to re-build or repair :shock:
If you wait too long it will damage the expensive parts :o

Jim,

Thanks - that is what I suspected. Rebuilding the drive line will be a lot easier now that the body is off.

At this point my teenage lackeys are still fascinated with the air powered tools, so they are pretty willing to help take things apart. It is mostly a matter of getting them to fit helping me into their busy schedule of video games and eating.

Now ins't this just cuter than a sack full of puppies?

Anyone know if it is possible to clean up the pressure plate enough to reuse it?

Ugh. I'm afraid mine looks like that inside. I just won't look. :shock:

Not sure if it's my rear main seal or the gasket for the timing cover, but I've definitely got an oil leak there somewhere.

Reseal the timing cover with anerobic sealer and replace the rear main seal. Loctite gasket maker is a common type. This is a zero clearance sealer that fills voids up to .050" and it wont degrade like silicone sealers.

Is that just from the lack of service? Doesn't look good. I'd have to say if any of my vehicles had parts that looked like that. I'd loose sleep at night just worrying about it breaking down on me. One would think the slug would create lots of heat.

Erik,

The oily gunk in the bell housing represents either a bad rear main seal on the engine, or a bad input seal to the transmission, or both.

This dis-assembly binge started when I noticed that the transmission output shaft has play. The input shaft has a lot of play too, I found out once I got it off. I want to use the 712 for trips into the middle of nowhere, and the concern you brought up about worrying is dead on. I am breaking down everything into (at least) major assemblies to check how things are doing. At that point replacing seals is a fairly inexpensive add-on to the project. I am also going to break open the diffs to see if the EX-II upgrade is warranted.

Here is the current state of my 712:

And no, there are no weapons of mass destruction involved!!

:shock:

are you sure.... it took me a little bit to see where the 712 was, or wasn't...

Good Luck on the project! :wink:

Not to change the subject. But what is the white and orange car in the back ground?

Erik,

That is a 1959 Hillman Minx. Pictures of one of mine:

and some general information:

Out of view, off to the right in the back yard picture is a 1998 Shasta Sprite 21' motor home on a Ford E350 chassis with a V10 engine. My son is helping me replace the rubber roof and add 4" of extruded polystyrene to make it nicer in the extremes of temperature.

Evan, Neat little car wonder why you like it? :lol: Suprized not to see any empty Tequilla bottles in the picture. Must of been a dry day or is it the day you put the bead locks on. :lol: Your up dated website looks nice.

Evan,

No "Weapons of Mass Destruction" to disassemble it,

...but you'll need "Weapons of Math Instruction" to put it back together!!

:wink:
