Hi all.

I am now on to a new problem that I think i created with reinstalling the drive axle. The drive carrier next to the friction plate is loose. When I am in slow(turtle) to mid forward speed. With the unit on flat level and in operating position, if I move forwards and backwards it knocks and almost sounds like a bell. I am thinking I made it loose by knocking in the roll pin in the axle. I have looked at this part and there doesn't seem to be a way of making it tighter, other then adjusting the speed rod up and down in the nut.  What can i do to make this tighter? Is it something to do with the speed adjustment rod?  There is two washers on the top and bottom of the drive carrier. They don't seem to do much in keeping it snug.

On the lighter side of things the wheels are back on and operating nicely. Everything is smooth, I also adjusted the belts today and that seems to be working great.

I'm on my way out the door until Sunday midday.  Your info is now very clear, thanks for the pictures.
It's good for me to learn how my next snowblower will look like inside (delivery has been postponed
till next week or the one after, don't know why).

Doesn't the fork itself keep the carrier (the half with the prongs) from rotating ?  I can't see that it
can get out of the fork.

I'll get back to you on Sunday.

Have a good weekend paul, when you get back watch the youtube video link i posted, I am sure it will make it much clearer as to the problem

They say a picture is worth a thousand words, I must say a video is worth a few thousand more.  This is the
first time I've seen a youtube video used to provide info in a discussion in an internet forum.  Impressive.

The carrier's movement looks perfectly normal to me.  There has to be a bit of looseness so things don't
bind.  I'd expect that the slack would be taken up one way or another when the traction is engaged.

Have you had a chance to look at what the other turning parts are doing when you turn both wheels at the
same time ?  Also try when you turn only one wheel at a time and the differential makes the other wheel turn
in the opposite direction just to see if the differential is making any noise on its own (you have the new
limited slip differential so I'm not entirely sure how it behaves).

Is that white stuff coating everything salt  ?  If so, no wonder you have rust problems.  I think you may live
near the ocean, but with the quantity of salt they spread on my street I wouldn't have expected that to make
any difference.  But I don't get salt on the inside.   There is a cover on the bottom of your machine I take it,
so is the salt just in the air ?

Exactly what I was thinking. I don't see anything abnormal...?

Hope you had a great weekend Paul.  I can't see it being quite normal as it didn't make that sound before. This is for sure where the sound is coming from. The Video was taken on a flat and not service posistion. I tilted the snowblower a little and stuck the camera up under it with a light so that you can see better. I am wondering now if I could actually have put in completely flat and rocked the machine back and forth and see if you would have seen what it was doing. The grey stuff is where all the rust was, I knew that would come up in discussion :) . Everything grey was sanded down a little and painted with a rust primer and paint. Hopefully to ward off future rust. Yes I live near the ocean, not right next to it tho. Probably about 20km.  Not many places in Newfoundland that are not near salt water.

I have not been able to reproduce what the differential does. When it was completely off the axle or just spinning the wheels in service postion. If I turn the tires, both turn.  But when I put in down and move it around it works. So maybe it needs more torque then I can give it with my hands spinning the wheels.

I don't suspect the movement of this part will create any problems just doesn't sound right when moving it back and forth. I can live with that tho.  At one point I was thinking of removing all these parts and trying to put one more thin washer under one of the existing to take up the slack a little. But if it needs slack, I will leave it.

Thanks Paul and snowman for having a look at it for me.

How does the machine behave in each of its forward and reverse speeds ?

Have you done the "Traction drive clutch adjustment" to make sure you have
sufficient contact between the friction wheel and the drive plate ?

The rubber on the friction wheel is clean and smooth ?

Paul

The machine is working great and adjustment done.  Just when I go to pull this machine back instead of using reverse it will make the bell sound.  because the carrier bearing is swinging back and forth depending on weather I pull forward or backwards. It swings on the carrier shaft and the bearing round arms that hold/slide are hitting the fork which causes the washer and the bearing to ring like a bell. Like I said, it only happens in slow forward and reverse. Its when the friction wheel is near the center of the friction plate. This cause the carrier bearing in the fork to become loose as the shift fork channels are  completely straight vertical. Where as when the friction wheel or speed is in the fastest forward or reverse. The shift fork channels are on a diagonal which tightens up the carrier bearing arms.  The channels on the fork are cut in it on a diagonal so I am thinking at any point it shouldn't be completely straight vertical, should always be on a slight angle to keep the bearing from falling forward and to stop the rocking motion. But not the case on this machine.

Its fixed.. Took the friction wheel and carrier out.  Put extra washer on the carrier bearing arms. Put it back in, wa la.. She is good to go. Was to much slack between the washers and the shift fork.

Thanks to all
