I installed new hex shaft bearings, the chain and drive do not look correct or in alignment. Can someone advise what I did wrong?

Thanks,

Does the bearing unit go on the outside of the frame?? --- John

The bearings are installed on the inside of the casing, the shaft is too short to allow install on the outside. The new bearings match the original parts and the part numbers match the owners manual.

The diagram is kind of funny, but areboth bearings supposed to be stacked on top of each other like that? The second picture you have shows stacked bearings. the first only has one bearing that looks more correct to me, per the diagram.

I think the lower ones you see are where the (wheel) axle mounts through with another drive gear and chain (not in the pic).

That all said, if the sprockets and chain in the pic are off alignment it may work but will wear everything down quickly.

Are the sprockets asymmetrical? In other words, could one or both be installed backwards?

 

[steddy]

It just looks in your picture like you have two #230 bearings, where your second picture shows two. On the larger (driven) sprocket, your picture looks to show one #270 bearing, which looks correct per the diagram.

No they are not, this is probably a simple fix but right now I do not see it. I compared my newer Craftman (2007) to the subj older one (1997) and the new one deos mount the bearings on the out side. The subj one does not have holes for the shaft to extend through the casing thus outside mount is not possible.

Enclosed are some more pics with the axle drive chain connected. For some reason the alignment to the top hex shaft is off? Any ideas are most welcome.
