Evinrude 35hp crankshaft

[Johnson110]

I got this crankshaft off ebay, when placing the crankshaft in the block the top and lower bearing have to line up with pin on block, if this is done the o ring does not line up with the block on the bottom, which way is correct, to have the bearing line up with the pin or use the bearing with the o ring on it, I have both types of bottom bearings. Thanks for any reply's !

Anyone?

I think I understand what you're asking, but to be certain, can you post a few pictures for us to see and you will get a lot more responses as well...

 

[Johnson110]

I will try to get some pictures posted. Thanks

Not looking over your shoulder but -------------The mechanical seal on the bottom bearing is installed after the crankshaft is in the block and the block is closed up.

The bottom bearing has a o ring on it, the block has a " dowel " pin for all three bearings, the bottom bearing has the o ring on it so it does not seat in the " dowel pin", i have the the snap ring off and remove the bearing, to check it I put the bearing back on the bottom and put the seal and snap ring all back together, but it this the way it get assembled ? Like I said where the o ring is on the bearing it will interfere with the dowel pin on the block . I am waiting for my son to take a picture of this to post. Thanks for the reply's, i really appreciate the help of you guys on this forum!

????-----I believe I said that the crankshaft and bearings are installed without the bottom seal in place !!

The seal in not the problem, it is the o ring that goes in the center of the bottom bearing, block has groove in it for o ring, however the dowel in will not go into bottom bearing, the o ring is around the center of the bearing, Is this how it goes back together, I should have taken a picture on it before taking the crank out.

?????????--------------The o-ring fits in a groove in the block , not the bearing !!!!

 

[Johnson110]

The bearing has a groove around it with the o-ring on it, this is what i am taking about, the block has a mating groove on both haves to hold it in, but the dowel is right below the bearing with the o-ring on it.

 

[racerone]

I give up coaching.

The o-ring DOES NOT GO in the groove in the bearing. It goes in the groove in the block. The two grooves are NOT related and DO NOT line up.

 

[Johnson110]

Ok, I have to get a picture of this taken and that should resolve the issue!

Here is a link to the pictures of what I am working with:

Don't know how else to explain it. The o ring simply does not, and never did, go in the groove on the bearing. If you look closely at the bearing, you will see where the Irving originally was placed, a faint line around the bearing case.

 

[Johnson110]

I just want to make sure that it goes back together the right way, so what i should do is place the bearing back into the crankshaft WITHOUT the o-ring and center the pin to the block, Is this the right bearing for the lower crankshaft ? I have two other bearings that look like the top bearing, I don't take apart these engines all the time, hence the confusion this is why I posted the pictures. I needed to have someone who knows how these engines are assembled.

 

[Chinewalker]

I believe the hole in the side of the bearing is off-set to one end of the bearing. The bearing rests against the bottom of the crankshaft, or at least should be able to (there should be a few thousandths clearance if the crank is pushed upwards with all bearings in place. The grooved part of the bearing goes between the o-ring and the crankshaft bottom lobe. It appears in your first photo that the bearing is installed upside down. Flip the bearing end for end so the groove is closer to the crank lobe, let the o-ring ride in the groove in the block and put that bugger back together.

 

[Johnson110]

Thanks. I put the bearing on i turned the bearing around i took the o-ring off the groove of the bearing and moved the o-ring into the groove of the block, so what I have now is bearing riding up bottom of crankshaft and o-ring in groove of block not in groove of bearing, Please reply Mr. Chinewalker!

 

[Chinewalker]

That sound like it should be.
