larryb Posted February 21, 2020 Report Posted February 21, 2020 Today after fueling the plane the Shaw 531 fuel cap lever was very stiff on one side. I found I am missing the washer under the lever. Spruce has something, but it looks out of stock. For now, after lube, it's working OK, but of course I need to get a new washer. It looks like a standard washer with a wedge cut out. No idea how long it's been this way, could have been before I bought the plane. My MSC has replaced the o-rings on the cap, they should have noticed the missing washer, but... The stiffness came on suddenly, it was fine just 2 days ago. Options of course are finding the proper Shaw part. Or measuring the washer on the good side, finding a generic replacement and cutting out the wedge. Or a used one on ebay, just for the washer, I see several. If anybody has dealt with this and has insight, I would appreciate it.

How about $10 plus shipping? Do you need fluorosilicone fuel cap o-rings too? Email me at gallagheraviationllc@gmail.com Quote
Igor_U Posted February 21, 2020 Report Posted February 21, 2020 $100 for a couple "nonmetallic" washers? Am I the only one who considers this crazy?? Even my IA would tell me to got to ACE and get thin Teflon washer and trim it... 2 Quote
N201MKTurbo Posted February 21, 2020 Report Posted February 21, 2020 I would get some SS shim stock and a Dremel. Quote

larryb Posted February 22, 2020 Author Report Posted February 22, 2020 Fortunately James was able to hook me up. For $10 it saves me a lot of time. Well worth it. 1 Quote
