Here's my procedure for reconditioning the springs and grubs. Dislodge the spring arms in the rep lever and jack. Straighten out (reestablish proper curve) to the bent, 'maladjusted' wires with specially adapted curved-jaw pliers (jpg). Remove encrusted lubricant from rep lever grub. Clean and polish spring end at rep lever contact with Dremel Tool. Place lubricant, usually DAG, in rep grub AND jack spring hole. You'll be surprised at what a little lube can do at the jack. Expand the spring at the coil and install spring ends to their slots. Reconfigure the bend at jack if needed. Sometimes it entails trimming the jack spring arm which can bind at the far end of the jack mounting. Adjust tension if too strong. Burnish rep lever at knuckle contact. -- Regards, Jon Page -------------- next part -------------- A non-text attachment was scrubbed...
