Pulsar Owners,

  

 For those with the Usher UD3 fuel cap this may be of interest.

  

 Over the years the fuel cap on the header tank of my Pulsar increasingly became harder to have the release lever snap closed and flush with the rest of the cap and its installation ring.  I replaced the two O-rings (large outside and small inner) with no effect on how well it closed.  I contacted Usher and they sent me a stainless steel piece to replace the small rectangular rubber piece (gasket like thing) that the handle presses into when the cap is engaged closed.

  

 What a difference!!!  The cap lever now snaps in place, truly flush.  I can more easily adjust the fit, turning the bottom half disc and drawing up the lock nut.  I understand there was a time when Usher made this change to the fuel caps they were producing.  May be worthwhile checking if you have this type.

  

 I don't see this replacement part at Aircraft Spruce so I believe that the only source is Usher directly.

  

 Fun, safe flying,

  

 Ronko

I had the same problem with mine. I disassembled them and found the piece was a bit worn and did not provide the over center lock anymore. I filed a new surface on it with the proper angle and it works again like new.

Question: How do you remove the jam nut to replace the O-ring and washer? The pin in latch broke so I can’t get a grip on post. Any suggestions???  O.K.

If the pin broke, can you remove the pin? Then you can just pull the latch off and the post out. I had a broken pin as well, and I got it out and reassembled it with a new one. Be careful, the edge distance of the hole for the pin is rather small. Otherwise, there should be enough of the screw sticking out that you could get a grip on that. Elastic stop nuts turn more easily if you heat them and the plastic softens.
