I am not sure if I understand what you are asking.....did you reinstall the pusher and find that it was out of tolerance, ie: less than .16 or more than .24 in. of the rod showing when it was in place? The pusher appears to have two bolts which may allow some adjustment, but the only written directions I have are what I previously posted. Maybe someone who has had to adjust theirs can give more info., but the Trooper forums are not as active as they used to be due to the loss of owners and dealers, so it could be a while before you get more answers. Can you examine the pusher and see an adjustment on the bottom of it? If not, then what about the belt pulley: does it have an eccentric on it somewhere that can be changed? Just some ideas to get you started. Good luck.
