Front bearing on a 79 6hp

[backhandman]

Should a bearing on the front gear be stiff? of should it spin pretty freely. The Bearing looks a little discolored. and it may have warped or expanded. A new bearing is around $60, I was wondering if it is suppose to be stiff. or could i take some fine grit sand paper and open up the brass bearing just a tad.

I'm a little confused on which bearing as well but he did list his 79,6hp in the Evinrude Johnson forum.
"Front gear bearing" being in front closest to the prop or "front" in the front of the gear case.

Presumably part number 0303380 ?

The gear should turn freely in the bearing and on the shaft .

Has the gear partially seized in the bearing so that the bearing is now turning in the gearcase? That would be a bummer because the gear case might be damaged.

I have easily found a source nearer $50 than $60 but that's still an awful lot of beer tokens for a simple bush.
I would try easing it with some very fine abrasive but do it carefully and symmetrically. A very light cut in a lathe would be better if you have access to one

We need further info about what type engine you are working on. Model number, manufacturer and year would help and even pictures would help tremendously. Post pictures and the numbers for us to get an idea what bearing you are talking about... Some times bearing, depending on the type of bearing, has numbers on then and can be obtained via other sources...for a whole lot less then marine sources!

He says '79 6hp what more do you really need to know if you assume its a Johnson or Evinrude

Sorry guys. 6R79E and correct. 0303380. Its more like a brass bushing that has some channels for oil to get into. if i can i was thinking about some fine lapping compound in between to free it up.

So it is actually the brass bushing that the front gear rides in, is it spinning in place? If so I would try the 600 grit paper and take a little off and see. Is the gear section free of burrs? You want it to be a snug fit but without slop as well. So if you go that route, go slowly and try. Also, I just did a really quick search and Evil Bay has a lot of them offers as low as $9 dollars. One place has both the gear and bushing offered for $30 dollars. So you have a few options there... Hope that helps!

There are a lot of bearings in any motor. When someone makes mention to the front bearing, is that in the foot, or somewhere else and not knowing how that person is seeing the engine (could be laying on his bench working on it) how do you seriously know what front bearing he is talking about. Front of the prop, front of the prop shaft? If he is talking about the front prop shaft bearing, he can remove that bearing and read the part number on it and buy such bearings in automotive part places for a fraction of the cost. I know, I've done that before. Same bearing and same manufacture. The marine bearing was list to sell for $56 but the same manufactured bearing was a mere $10 for the exact same part...that being Timken manufactured with the exact same part number!

Not many gears in '79 6hp though.

Obvious place to look was the gearcase, because that's where the only gears I could think of are located, and there lo and behold is a bearing called "BEARING, front"........... Bingo.

Front is front in my book too which ever way you lie down.

Very probably a bronze rather than brass but that's splitting hairs rather.

Not keen on the idea of lapping compound. look at it carefully it may be scuffed and ll you need to do is remove any raised metal with a piece of fine emery cloth wrapped round a wooden dowel,

Be sure to remove all traces of abrasive whatever method you use


BTW my 6hp is a little later and has a roller bearing in that location. I guess they found the bronze bush was not the best idea so improved the design on later models

Thanks. One thing that crossed my mind was taking the gear and bearing to my local Johnson/Evinrude shop and asking to see how free it is suppose to be. I know they have it. but they want $65 for it...
