The damned Simmering® in the bearing plate

Uncountable are the curses of Max amateur craftsmen who tried to change the Simmerring® in the bearing shield. The installation of a new Simmerring® 's no problem, but first you have to remove the old.
Today most hobbyists is an inert gas welding device. At least one knows one has one. With such a protective gas welder is the expansion of Simmerings® for pure joy. And it goes like this:
First they removed with a knife or the like the rubber or plastic inner parts of the old Simmerring®. Then welded to the protective gas welder already mentioned a thin metal strips (0.7 to 1 mm thick, 10 mm wide) of the remaining metal ring of the old Simmerring®. This now has two effects: First, the heat introduced dissolves the tight fit of Simmerrings® and secondly , one now has a "handle" on which you can pull out the old Simmerring®. If one example clamps the welded sheet metal strips in a vice , so dissolves lightly with a hammer every Simmerring® in no time.
For the bearing shield this expansion method is very gentle. Since aluminum is a good conductor of heat, it nothing happens, even if the iron glows Simmerrings® locally. Careful work is of course a prerequisite. Very proven automatic welding helmet , which only darkens the ignition of the arc has this (but which welder I'll tell you that. Anyone who has worked so again, the do not ever want another).
After the old Simmerring® is now finally out of the bearing plate out, it comes to the installation of the new. I recommend the execution "rubber outside" to use. (At Freudenberg "SIMRIT" called this version "BA" , other manufacturers may be different.) In these Simmerrings® the metal support ring is complete , including the outside, rubber or plastic coated. Besides the spring one sees no metal in these Simmerrings®. This soft outer surface they seal better in the hole and can also be mounted easily. These benefits are likely to be worth the small fee.
Before installation make sure you clean in any case, the receiving bore in the bearing plate carefully and if necessary, the edge deburring.
Best method (specified by the manufacturer!) For installation: On a mechanical or hydraulic press of Simmerring® is a special ram pushing on the base between the outer ring and lip pressed.
Second best method for mounting (for hobbyists): The Simmerring with a spike of hardwood or soft metal (copper, aluminum), which is slightly larger than the outer diameter of the Simmerring, hit with careful hammer blows.

Third best method (botch, guaranteed again soon leaking): The Simmerring® with a thin spine, etc. By Driver hit by blows to the outer edge.

So, now no longer say that he could not get out of the bearing shield the Simmerring®.

Simmerring® is a registered trademark of Carl Freudenberg , Weinheim. Actually they're called radial shaft seals. Note: As the only Cognac from Cognac to Cognac allowed to call, then only the radial shaft seals from Freudenberg shaft seals Simmering® may call.
