wordsmith07 Posted September 5, 2016 Share Posted September 5, 2016 Hoping for some advice on tuning a LG 50# hammer ( new style) I just received. Hadn't been run in a few years and clutch pulley was nearly stuck with old grease and would not release. after replacing alemite fittings finally pumped enough grease to somewhat free it. The original 3 phase motor is rated at 900 rpm so it looks like at best I can get 180 bpm with current pulleys. The ram was sticking at TDC until I loosened the top gib somewhat but it still seems to have friction there to change rotation where it is not smooth. The clutch does not grab as well as I think it should but still tries to run-on when I release pedal. I can stop rotation by hand so it is not dragging too much. Seems not to be hitting very hard it wont demolish 3/4 walnut like 25# on youtube. Do the rams often need facing or scraping and should I remove ram and inspect? I am lubing with bar oil liberally and moly impregnated grease on front and back. I checked end play which is 25 thousandths. One more question, when I started to lift from mainshaft near rear pulley when installing unit and noticed some vertical play in shaft.. Best I can measure, it has 10 thou play upward after removing v- belts. The babbitt shims look pretty thick and wonder if I should remove one near the rear pulley. Any help appreciated..

jmccustomknives Posted September 5, 2016 Share Posted September 5, 2016 Are you coming to the Forge Council meeting this weekend. One of the demonstrators will be showing how to rebuild and adjust those. Probably would be worth coming to. Quote Link to comment Share on other sites More sharing options...
wordsmith07 Posted September 5, 2016 Author Share Posted September 5, 2016 I am coming for the meet. I know he will demonstrate the 25#. Hope much of it applies to the 50#. Quote Link to comment Share on other sites More sharing options...
