daansley Posted April 3, 2010 Report Posted April 3, 2010 The cams are worn out on my Mooney M20J fuel tank caps. They don't snap flat anymore. New caps are more than $400. Wow! Best price that I've found (so far) for used caps that still have some snap left in them is $175 each. Part number is 431-9R. Can the cams be repaired? Thanks. Quote
Piloto Posted April 3, 2010 Report Posted April 3, 2010 Did you try tightening the shaft nut? Try this first before buying a new cap. José Quote
fantom Posted April 3, 2010 Report Posted April 3, 2010 I'm willing to bet all you need is a screw adjustment to the shaft nut as Jose suggests. Replace the small o-ring while you're all it. Quote
