j hancock Posted March 27, 2019 Share Posted March 27, 2019 You could check with a PAI dealer for a cylinder or a rebuild kit. 1 Quote JimIt doesn't cost anything to pay attention.

Freightrain Posted March 27, 2019 Share Posted March 27, 2019 Is it like the old air shutter cylinder on my B? It basically has a rubber cup seal that is held onto a rod with a small nut/washer. I was able to find a matching new cup seal and rebuild mine. Works great, no leaks. Quote Larry 1959 B61 Liv'n Large......................

If you run out of option you can send it to me as there is an older gent whom will repair it with pretty quick turn around. I've had him do a couple for B series and one R and they don't leak. In the meantime pull the rubber boot back and get some WD-40 into the area to saturate the seals. Older ones were leather and took to this well.

Freightrain Posted March 27, 2019 Share Posted March 27, 2019 I found my post from working on my cylinder. Though I didn't post the part number for the cup seal. I found one without the hole, but that was easy enough to punch out. Quote Larry 1959 B61 Liv'n Large......................

Mike Posted March 27, 2019 Share Posted March 27, 2019 If you get it apart, take the rubber with you to match it at a Industrial Rubber Company. That is what I did.
