[QUOTE="Chris Launders, post: 107133, member: 2010"] I have also previously converted an AMC box to the Dollshead/Laydown/Manx worm type lifter which is even lighter, it requires another cable boss welding on the housing but inside all that is required is to turn the OD of the brass worm outer until it fits in the roller/pillar retaining ring and braze Iit into the ring and make a spacer to replace the roller/pillar flange. Look at a Laydown or Manx box as to where the new cable boss wants to be. As to oil on the clutch that's what I've been suffering from with my Atlas just now, it has a Commando clutch and belt drive and has been getting gear oil on the plates which then stick together making gearchanges horrible, last night I attempted my own seal solution (being from Yorkshire I hate spending when I don't have to) So I got a spare clutch nut and brazed a washer on with a 1/4" clearance hole in it, got a piece of 1/4" rubber and punched a 1/4" hole in it (of course being rubber the hole is smaller than 1/4") trimmed this until it fitted the nut and then fitted to the mainshaft end with Loctite so it was just nipping the rubber, the future will tell whether this has worked, if not I shall have to buy one, Norvil do them for the Commando and Dommi as they're not the same.
