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

Same procedure, tighten until the pivot binds substantially, then back off both nuts between 1.5 and 2.0 flats (ie between 1/4 and 1/3 revolution). But don't bother to insert the cotter pin

BTW, a friend of mine recently reported stripping the nuts, trying to force new "lock" washers onto the splines. I suggest using ordinary hardware store nuts (which are thicker and stronger) to force them on the first time; plus if the trunnions are also new, using a file to 'break' the edge a bit where the splines get formed. But none of this applies if you are reusing the old lock washers (which is what I did).

Thanks for the info TR3driver
