help, see picture of snowthrower

[Superglyde]

Hi all,
I was blowing snow the other night and heard this terrible screech. The blower kept on working, but it sounded like I sucked up metal. In preparing for our next 8 inches of snow tomorrow, I took a look. The yoke (is that the correct term) where the chain is, wobbles around when you grab it, and it looks like the chain ground off the left grease nipple. The shaft I can move from left to right as I turn it and the sprocket rubs up against the left side of that yoke. I can't see how to make it all tight. Is it simply a matter of tightening up the chain with those two tightener bolts to push back and the pressure keeps it aligned correctly?

I'm a cub rookie, but I'm gonna guess your needle bearings are toast. The shaft that holds the sprocket has 2 needle bearings, one for each grease zerk. How often do you grease her up??

Do you have a closer pic??

I tightened up those chain adjusters. The chain is tight, but it moves freely and the shaft does and the wobbling stopped.
you can still slide the transfer shaft from side to side if you grip it tight and pull it over, but it does not seem to be rubbing on that sprocket bracket.
I probably need to replace it and those needle bearings, but if it will just work long enough for the snow tomorrow night, I'll be happy.
now the question is how to get it all off.
Thanks Sminkey!

what model thrower do you have??

Here's the manual for it: http://ccmanuals.info/pdf/QA%2036A%2...s%20Manual.pdf

Comes apart pretty easily, the manual doesn't show that though. If you have trouble with it, hit us up here, we'd be glad to help out

thanks Sminkey, I have that manual and youre right, it doesn't show much at all and I looked for a service manual and couldnt find that. I did find a blow up of the parts.
I wonder if the grease fitting is a speciality item or I can find one to fit?

not sure there is a service manual. I'm sure the zerks are standard issue, not sure what size though, someone here does, or just take out the other one to match it up with new one.

You can probably use the parts lookup to determine what size the grease fitting is.

The shaft in held in the bracket by the coiled pin in the sprocket, and
it rides in two captive needle bearings ( meaning they can't fall out unless the cup is destroyed)
The chain does not/should not, need to be tight.
It needs to be snug with a little up/down movement @ the TIGHTEST point, while revolving the sprockets.
----This is as you would adjust any chain.
Loosen the adjustment bolts and check if the bearings are gone by wiggling the shaft in the bearings.
If they are gone (like in missing) you have/will ruin the shaft and the bracket, if continuing to operate.
The bracket is no longer avail. from CC
If the shaft is snug in the bearings you have lost nothing and will be able to adjust the chain properly now.
----Gut feeling is the bearing/'s were dry and that is the squealing you heard, and the damage is done.
