Having trouble sourcing a new or good used AAR valve, all help much appreciated. Can they be reconditioned?

Ian Stott Moncton Canada Soak it in a cup of kerosene for a couple days, then give it a couple taps and blow it out. It usually frees them up for years of sitting stuck. Easy to bench test it after to verify its working properly by timing the valve operation. |

OK, I was calling it the wrong thing! It is sometimes called a decelleration valve, mine needs replacing but my searches come up as it being no longer available, can it be reconditioned?

Pretty much the same procedure. Soak it in a penetrant of your choice. Blow it out with compressed air (carefully). You can test it with a vacuum pump.

Check it with a vacuum pump at the small nipple and see if it holds vacuum and whether the valve opens when you apply vacuum.
They have a rubber diaphragm so you need to be careful what you use to try to clean them as some solvents or oils will break down the rubber. Put a WTB ad in the classifieds, there are working used one out there. Jim |

Posted in the WTB section, hope someone responds! Going to do the soaking in kerosene method as advised by other members, will post my results.
