TheSamba.com :: View topic - Out with Rusty old Flappers...In with Good Solid Used Ones

Tue Jun 12, 2012 6:08 pm

Spent last Saturday morning, replacing my old Swiss Cheese Heater Flappers, with some good used ones I was able to source.

I have had the side dump tubes on the Bus since we have owned it, and was waiting to source the correct Flappers. Now only thing I am lacking is the hose to join the two to discharge pipes. I've curious if anyone knows the diameter of the hose and a source for them.

Here are more photos, I said Swiss Cheese :lol: The joys of a Midwest Bus. Relieved to have them back to solid.

Thanks-

I feel your pain here in Missouri my friend. I can see why you might not have any heat with those in there. I restored mine last year. While they didn't have as many holes they were bad. I dipped them in phosphoric acid to remove rust, then patched the holes with JB Weld. I put a thin ring of cork on both sides of the flapping mechanism inside to seal and some new springs. Now they work great. Mine do not have the dump tubes though.

You do, you've got the pipes and must have a FLAPS nearby, take the pipe to your FLAPS and get the appropriately sized piece of aircleaner preheat hose.

Congratulations on fixing your heater :wink:

If I remember right, they are an odd size that is just slightly too big to use a standard size tube as is. I used a Harbor Freight exhaust pipe expander to just slightly enlarge the flexible tubes to fit.

Thank you for the replies. I was going through a parts box in my basement, and came across a small section of hose that was the correct diameter for one side. Plan to take that to the locally owned FLAPS, where I get alot of my Bus parts from. Wonder why the size is so odd and not a standard size?
