Shimming Evinrude '82 70hp pinon gear

[gibbins]

Does anyone know how one would go about getting the special tool used for shimming in a new pinon gear? Or, better yet, the dimensions of one .<br />Thanks,<br />John

you can buy the special shimming tool kit thru any dealer, but it is very very expensive, especially if you only need it once. <br /><br />Your best bet is to take the bearing housing, bearing, shaft, pinion, and nut, to a QUALIFIED mech and have him do it. It should be done in less than 1/2hr.

Thanks for info. I'll check it out, but you are probably right, might be prudent to have it done, if I can find the right person. I am somewhat reluctant, after having some real bad experiences with "certified" and "qualified" marine mechanics. I may buy it then sell it on e-bay or something. Thanks alot.<br />john

i had to put a new thrust bearing on my 70 horse and and take my shaft to a lathe and turn it down and i put it back together by feel to where i had just a very little slack and it is still running and that was 6 years ago i dont think there would be enough difference in the gears to worry about it i dont like marine mech or the ones i have delt with very well either they was going to charge me 300 to check mine i could get a rebiult unit for that lol

Thanks for the input. I don't have a lathe (yet!) or ability to do any machining myself, so I'll be looking for a way to do it by shimming. Glad yours has worked so well for you!<br />john

I THINK the dimention for a 70hp is the same for a 90hp. (not 100% sure)<br /><br />7.511 US You need .020 US between bar and bearing housing.<br /><br />If you wait a day or so, I'll let you know for sure. I'm in the middle of changing a driveshaft on a 1980 70hp, and will need the dimention as well....<br /><br />Maybe someone else knows for sure???
