The manual says:"To give the required end float,tighten the two castellated nuts equally untill the assembly feels solid. Next turn back the nuts betwween 1/2 to 2 flats untill the split pin holes are visible.Lock the nut with a new split pin.This gives the end float of0.0004 0.012 in." How is the end float obtained using lock nuts on trunnion without split pin holes. Thanks in advance for any advice. I think this has been covered before but I cant remember the procedure. Karl
