I agree with BillW that a few pics might be helpful in determining the fitness of the dog and gear. Assuming that they are OK, the shift lever can be adjusted as well as any shift cable that may be involved. It is important that when you push the shift lever forward in gear that you can feel the dog rub the forward gear. By rotating the propshaft back and forth you will be able to feel the face of the dog rubbing the face of the gear at the bottom of the engagement face. That may be a little hard to understand, but you are looking for as much engagement as you can accomplish. The shift lever is adjustable on its shaft to help you achieve this. If you get full engagement in forward gear and still jump, you have a gear/dog problem. Several on the site have talked about putting a negative two degree ramp on the dog and gear to help them lock/pull themselves together. It is important that both lugs pull together. Pappy has talked about this before. Maybe he will chime in again. Easily done on a milling machine with a degree head and smaller HP is not as critical. New gears are pretty expensive so you don’t have much to lose in giving it a try.
