[diesel_mercedes] Thumping noise [1 Attachment]

 
[Attachment(s) from Bogy Wan Kenobi included below]


Thanks for the suggestion to check the driveline. Carrier bearing is still solid. But the front guibo was toast. Apparently it matters which holes go to the tranny and which to the driveline. There are thick sections and thin ones. These are stronger in compression that tension and pushing through the thick section is more better than pushing through the thin ones while pulling the thick ones.I have removed and reinstalled these dozens of times over the years and apparently luck failed me this last time when the front one vaporized.
Color me relieved and happy.

It will be two wheel drive at first. it was easier to adapt an american drive line to the output of the german transmission than anything else I could think of. I'm actively looking for a stand-alone transfer case for a right side front pumpkin and when I get that I will make it 4 wheel drive. I made a special adapter plate to go from the back of a German transmission to mate with 1310 u joint yolk and that is how the Germans and the Americans are interfacing. I'm doin' this on a thin budjet.

See the pics.

1) Six-bolt pan.
2) I dunno.  $50?  That includes torque convertor.

It came out of an '82(-ish?) TD I bought at a salvage auction.  I drove it the 8 or so blocks from the auction site to my shop.  Other than the twisted left front fender causing severe tire gouging, the car drove and shifted just fine.  Might want to confirm it has the latest B2 servo upgrades before installation.  Easy to do on a transmission that's not installed in a car.

Interesting that you're using the MB tranny in your CJ conversion.  Are you going to have 4-wheel drive?  I'm going to be using the AW4 in my XJ using these guys' kit:

I'll use the RAdesigns shift adapter.  It will be a manually shifted automatic, which is fine with me.

Guibo is that round rubber disk at each end of the drivelines. But about the tranny . . . I'm currently putting one of these engines in a jeep CJ7 and as of now it is mated to a 4-bolt slushbox. That should be very adequate for a light weight rig like a CJ. So 1) is yours a 4 or 6 bolt pan and 2) how cheap is really cheap.

BTW, thanks for suggesting the carrier bearing mount. That's easy.

Not sure what a "guibo" is, but, the the symptoms sound like classic drive shaft carrier bearing housing failure.  The bearing itself is likely all right, but the housing is made of rubber, and often fails.

Doubtful it's the transmission, but if you need one, I've got one that I'll let go real, real cheap.  Just need to get it over the mountain to you.

Are you by chance suggesting guibo failure. Cause that would 'splain nicely.

[diesel_mercedes] Bench Bleeding The M/C

 



Three short brake pipes  one screwed snugly into each outlet and bent to pour back into the resivoir .

it's far easier and better to simply use a simple pressure bleeder , no pain destroying and rust causing brake fluid drips .

I do not bench bleed .

-Nate
       Max Asked  :

When you bench bleed your new master cylinder do you need 2 or 3 plugs? Max

[diesel_mercedes] THUMPING NOISE

 



Around the vetical bolts that hold the entire rear subframe to the unibody ~ there are multiple BIG rubber bushings in there that are labor intensive to replace but not terribly expensive .

Any time you see rust or suspicious cleanliness around a bolt , screw , nut or washer , it means said fastener isn't holding tight and needs attention straightaway before things get ugly .

Not quite sure what you mean Nate. I had a moving observer follow me as I accelerated about 10 or 12 times and they could see nothing unusual in the behavior of the tires. Where should I lok to find these clean (or rusty) marks?

Before you panic ;

Take the time to look hard at the rear sub frame bushings ~ they'll _look_ fine but have either clean or rusty marks around them if the sub frame is shifting from shot rubber bushings .
