|
|
I had to clean and rebuild mine and could not find any pictures or any good instruction what to do so here is some pictures what to do.
And as a side note I must say that I am not a expert or anything in this stuff.
Directly out of the car you can see the adjustment screw and scale on the body of the aar.
Top cower remowed.
Shaft pushed up and off the bi metallic spring.
Better pic of the adjustment.
The shaft of my aar was really tight (tight enough that bi metallic sping would not turn it) to the body of the aar and cleaning an polishing did not help and finding a replacement part ower here might be hard so I decided to put some metal polishing compund to the tight part and spin it gently whit a drill. Few cleaning and retrying later I got the shaft spinning freely.
After this I cleaned all whit carb and brake cleaner and reassembled whit a smear of molykote BR2+ (slide bearing grease)
When everything was back to gether I adjusted the thing in water to fully close at 50*C I tested the fully closed position by blowing to pipe that I attached to the aar.
I also did a new aar to the engine seal from a regular fuel pump seal.
And here are some test pictures showing the aar opening.
~20*C
~-15*C
So I hope that this helps someone in the future.

Excellent tutorial and a thorough job. It's rare that one is found that stuck, but it happens! _________________ Немає виправдання для війни! Я з Україною.
