I am trying to help my father fix his MF35 He has not had it very long, and while using it the other day it stopped steering to the left and was making some popping sounds coming from the steering box.(it has power steering with the slave cylinder attached) He thinks the sector gears may be the wrong ones but we are not 100% sure of that. He has a book on it and in the book the gears mesh together well. BUT the ones he has in it just barley mesh together at all and there are no Align Punch marks on them. So we are thinking that the people before us had to repair it and did not use the right ones for the Tractor. Also when I look online at parts there are a couple different types of sector gears available with different amounts of teeth on them. So my questions are: how many teeth should there be? Should they mesh together all the way like in the book? And does anyone have any suggestions just in case I am way off base with the whole sector gear thing. Please can anyone help???
 
Just off first guess I know that the manual steering gears vs the power steering had a different number of teeth. It may show on the parts breakdowns how many teeth which has, try www.agcopartsbooks.com for that. Also an original TO35 may be different than the later 35's or 135's, good luck to you. Make sure the "worm" on the end of the steering column moves free as well.
 
A manual box has a 9 tooth, and 6 tooth sector gears, power steering has 8 tooth, and 10 tooth sector gears. Sounds like they tried to put a old manual sector into the box just to get rid of the tractor. You can either find a used set, or just get a new set from YT. Replace them both as a matched set only, the OEM (if you can find them), and aftermarket parts are a little bit different, went through this same thing on my brothers 135.
