Finish mower options

To me it doesn't look that bad.
But if you think it's bad, one trick is try spinning the shaft 180° on the shaft.

Ok, thanks. I thought the third video shows it looking pretty bad. I'll try spinning it 180 degrees and see what that does. I was also going to try it again this morning with grease as the splines were pretty dry from cleaning and handling. Unfortunately it wouldn't start - it turned over but was really sluggish. I tried a second battery and a jump start with the same result. I've now got a battery on charge overnight and will try again tomorrow. I kicked it and headed inside to watch the Aussies play Paraguay in the world cup - I'm not a soccer fan, but don't mind watching these games.

Could the sluggish to turn over also be caused by a starter motor on the way out....worn brushes, high resistance ?

Good morning Paul. The experience I have with drivelines is connecting and disconnecting implements, so I'm far from knowledgeable. If your pictures were all taken without moving anything between shots, I wonder if your joints are out of phase.

EDIT TO ADD: I posted the above before seeing the most recent posts. It appears the joints are close to 45° out. Shafts I'm familiar with have joints at both ends and a sliding shaft that is automatically indexed via odd-shaped lobes or something like that. A shaft with a u-joint on one end and spline on the other can be assembled in perhaps 32 different relationships, with most being off. I don't know how much each spline would count. Maybe a shaft made in a joint-x-spline configuration would need both intended joints in the right rotation before welding the spline to the shaft?

Thanks Chim.

The yokes at the green and red arrows are aligned - I think this is how the original shaft was, but now you've got me guessing. Not sure if that means they are in phase or out of phase.





EDIT: I just asked Google - looks like I have them in phase.

Pardon my incorrect observation. In the pictures it looked to me as though the two joints were at different angles (rotation wise).

I may have bumped it between photos, or it may be the angle of the camera ? I didn't really pay attention.
