I have some pretty strong vibrations above 22-2400 rpm in a 1996 H280 w/ 2GM20F and rattles your teeth at 3000. I've read all the archives and feel as though I can do an alignment but am not sure what to expect on a few of the points. The Hunter manual says:1) "Establish the shaft in the center of the shaft log (stuffing box assembly?) by raising the shaft until it touches the top of the log . . . . lower the shaft until it touches the bottom of the log . . . etc" Q: How much play should I see here; 1/8", 1/4", 1/2" . . . ?2) "Now adjust the engine mounts to allow the pilot on the coupling halves to slip together . . . "Q: Will the shaft flange move very far back away from the trans flange? Is the pilot in the center of the flange(s)?The rest is pretty straightforward regarding the gap tolerance between flanges. Q: Are the bolts for the flanges and engine mounts metric?Q: What tools are used for horizontal adjustments? Seems like getting .004 would be pretty hard by adjusting the base of the mounts? Thanks all for your patience and help.
