Just because a hammer swings only 3 times doesnt neccessarilly mean its too tight per se... too much friction can be caused by other things then simple tightness... but then you knew that didnt you Wim. :) If its 10 - 12 swings with Protec the bushings are not tight enough to hold the hammer solidly on path for medium to hard blows. If after a day or so its back to 5 or 6 swings ... or less... then you have gunk in there Proteck cant get rid of for you. So you'd better repin anyways. This is a job that ya'll can get real good and quick at and has a big pay off. Ream and burnish the old bushing and add a tad of Teflon powder, and repin. Makes all the difference in the world and lasts a long time. Cheers RicB > > > We all know that a hammer is supposed to swing 4 - 8 times. If it is less > > than 4, then the bushing is too tight.
