blaven Posted October 9, 2017 Share Posted October 9, 2017 Even though I say it myself, my cassette is sweet as a rose,-(not like that disgusting YouTube refurbishment video) The only slight leakage I have during a carry is from the AHTV. It’s the old original type, bayonet fitting with three lugs. The plunger which is depressed to open the valve upon insertion of the casette is sticking in the down position. So I’ve stripped it down and cleaned what little residue was present and I notice on the shaft of the t-shaped plunger there are two grooves, only the bottom one of which has an o-ring. Should there be another halfway up the shaft? I’m thinking that the middle groove is hanging somewhat on the white nylon disc in the body of the unit, preventing the spring from returning the piston back up. I know that replacement of the whole unit is possible, but I’d rather restore the function of the original and save myself some cash. Link to comment Share on other sites More sharing options...
blaven Posted October 11, 2017 Author Share Posted October 11, 2017 A bit sad having to reply to my own post, but having added another o-ring to the empty slot on the valve spindle, and having lightly vaselined both rings, all is functioning again as it ought.
