Hi Guys,
Are there any tricks or tips to fitting the rubber rings which support the exhaust / muffler? I am referring in particular to that long one which fits in a recess in the middle of the system.
Regards
Peter

What's real handy for this is a kind of 'hook thing' with a handle, something that lets you stretch the rubber donut while you work it onto the bracket. I use a large screwdriver but there are special-purpose tools for this.

Love the technical language on the forum - "hook thing"
A cotter key pulling tool may be what you can use. Here is one example

Hi,
I use a tool like Cees describes, similar to this:

Sometimes together with a large flat headed screwdriver for prying the rubber ring
In place.
Non original rubber rings are sometimes a harder to work with than MB rings.

Heating them up in hot water helps too.

My experience is the Mercedes rubbers are more pliable and do not crack as quickly as the aftermarket o-rings. I have seen aftermarket o-rings crack in less that 2 years so spend the $1.00 more.

Install the rubber ring and the upper part of the hanger first, then raise the muffler and attach the bottom part of the hanger.

Guys,
Thanks for your posts.
The 4 round rings which are fitted to the rear box are relatively easy. Mine came as part of a non oem exhaust kit so following your advice l will be careful to check these for condition on a regular basis.
The long one in the middle though is the stuff of nightmares. This one is an original from MB (A1114920082) - my car is a W111. After a bit more research I suspect that the W113 does not have this ring.......and I can understand why. The hooks for it are inside a recess in the floorpan. The recess is just big enough to get the rubber ring in. I found it impossible to apply any leverage to stretch the rubber once it is in the recess and fitted over one hook.
However I will invest in one of the tools suggested (thanks for the link Hans) and try the hot water technique. What are we talking about here - boiling point? I guess these rubber rings are designed for taking heat bearing in mind the application.
Regards

Doesn't have to be that hot. After all, you have to hold these things when you take them out. 150*F should be plenty to make them pliable. Let them sit in the hot water for a while because you want the part to get warm all the way through. Rubber is an insulator after all.

Hi Jon
That tool you described is used by Joe for removing radiator hoses from the radiator.
I purchased one from Harbor Freight and it works greats on the radiator hoses. It sure beats a screw driver that I was using for the last 50 years.
