“Exhausting” experience

[dirkbalter]

Michael,
I am not the designer either and assuming I installed them correctly, i could see that these act as some kind of heat shield, protecting the rubber.

ive changed several times the dougnut type. they do not last long.

I've also changed mine several times (rubber donuts) but after Michael's misfortune, I'll make it a point to check the donuts whenever I'm under the car.

I definitely do not have those heat shields, and never did. I wonder how many other Pagodas are similarly situated. I am going to try to get them, and when I get the new replacement muffler/resonator parts, and reassemble everything, I will reassemble it with the heat shields.

The Classic Center is sending the heat shields today.

Thanks, Dirk Balter for the great photos!

Yep, installing the heat shields correctly, will prolong the life of the rubber donuts.

Prior to going to Pinehurst earlier this year I was doing my pre-trip check and found that one of the rubber exhaust doughnuts at the back of the rear muffler had come off but was still hanging on the body hook.  The culprit in all this was that the single clamp nut and clamp underneath the twin rear pipes that secures the rearmost hanger to the topside of the twin pipes had vibrated loose and were lost on the road removing any tension from the rearmost hanger.  Authentic classics had the part, and Lowes had a nylock nut.  It just took a moment to stretch the rubber doughnut back into place and then replace the bottom clamp and tension everything up with the nylock nut.

I was thinking of using nylock nuts for those hangers (if you mean self-locking nut with nylon insert), but was afraid they will not last in high temperature. So I just used two nuts. Not sure if I was correct in my assumption…

[Cees Klumper]

There self-locking nuts other than nylon to deal with heat: the standard ones to secure the exhaust manifold to the head are an example.

Here is a heat shield. MB Part #000-492-09-83. List $11.00, with our discount at the Classic Center, $9.00 each.

These are marked “Reinz AFM 32/2” https://www.reinz-industrial.com/en/products/afm-group/afm-322.aspx

They need to be installed as shown in Dirk’s photo—between the rubber donuts and the hot exhaust pipes.

Do you have these? I did not.

[wwheeler]

That is just a standard non asbestos high temp gasket material. Same as what I have on my car. If you had a pattern to go by, could easily buy an equivalent material and cut your own. For $9 though, hardly seems worth it.

[mdsalemi]

…cut your own…hardly seems worth it.

Many here want only the precise parts from MB for their cars, when available. Not aftermarket nor homemade. Since many are apparently in the same boat, missing these heat shields, my prior post indicates exactly what the OEM part looks like, its size, its part number and price.

If one didn’t care about these things well the wired scheme we used to temporarily hang mine in Chicago is probably better than rubber! I had no rattling at all (thanks to David Robinson’s under car engineering) for two solid days driving home. The developing holes were another story…

I cannot believe nobody ever mentioned to me the missing heat shields prior. Over the past 20 years my car has been on a lift in a number of places for a variety of reasons, and the rubber donuts changed now and then.

Always learning something new!

When my new resonator comes from TimeValve, it’ll all be put back properly for the first time since restoration.

Those beautiful and correct photos didn't help your shift bushings! (wink)

[thelews]

Sure didn't.  Hidden and decayed, at least the lower one.  Surprisingly, the shifter felt quite tight until it failed.  I do notice a difference with the new one, but it's not dramatic, let's say if new is a 10, old was an 8.  Unlike the 190 SL, when the shifter bushings are going, it gets very sloppy.

Michael,

I am afraid you misunderstood my statement. This is what I said -  "For $9 though, hardly seems worth it." Meaning that for only $9, why not use the MB part instead of making your own. I did not imply that you should make own, only that you can as an option. This is not an exotic highly specified material.

[Kevkeller]

I’ve got a simple tool I bought years ago that makes installing the donuts fairly easy. I’ll try to remember to take a picture. Ping me if I forget and you need a picture.

Michael,

Thanks for your post! I never knew of these heat shields as well. I guess I didn't pay much attention since I had seen the exhaust schematic many times. For me I've always strived to have my car as original as possible and when I see a part for $9 bucks,  I'm always happy about that! Mine are on order and will change out my donuts when they arrive.

To me that's what our site is all about, sharing experiences , the good and bad, so all can learn about our Pagodas.

This.  You use a twisting motion instead of a pulling motion. Works well.

[ja17]

Nice exhaust John L.  Correct color, all the bits and pieces correct, connector pipes oriented correctly and all welded connections. Factory correct!

[thelews]

The credit goes to Vince Canepa.  It was his car for 37 years and he was a stickler for factory correct (except where he thought he could improve).  I've just maintained it for 15 years.

Sure didn't.  Hidden and decayed, at least the lower one.  Surprisingly, the shifter felt quite tight until it failed. 

And hence we learn that "shakedown cruise" never really ends. Nothing like a good long drive to bring out the worn (or missing!) parts. Glad to hear your shifter is back up to 100%.

Thank you, TimeValve!

Immediately upon returning home from PagodaFest, when I installed all new rubber donuts, ordered the missing heat shields, I noticed holes in the muffler and pipe…from dragging on I65 in Indiana. 😞

I called TimeValve and asked for the partial system, next time he had the jigs in place to fabricate the W113 systems. Some owners must have ordered some systems in the past couple of weeks, as my partial system just shipped!

Great folks to work with!!!

Does Timevalve have a web site?  The one that comes up with Google search says it is not longer active.
