Re: New owner of Hymac 580 B

This old working horse is retired, so i think it will hold pretty good. If not i can always make a welding repair later. :)

Re: New owner of Hymac 580 B

I also opened the gearbox on the other side. Like on the first side i pull the head of every screw. Drilled new holes and made new threads.
To my surprise it was no water in the oil and all the gear was in pretty good shape. I drained it, flushed it and refilled with new oil.

Re: New owner of Hymac 580 B

I strarted to make shiming material yesterday. I used special shiming steel, heated it and smithied it over the teeth. I knocked it in a bit and all the clearence dissapeared. I think with strong loctite it will last quite a while.

Re: New owner of Hymac 580 B

Yes my first thought was to weld it and grind it to the right size. But as i dont have a slotting machine it might be expensive. On the sweedish forum "Maskinisten" Some guy adviced me to shims it with thin metal plates bend over the teeths to get rid of the clearance. Than fix everything ...

Re: New owner of Hymac 580 B

To my surprice i find the bearings on the other drivewheel to be in pretty good shape. The clearance must be in some other place. When i removed the driveshaft i find the problem. https://www.youtube.com/watch?v=OwHT8TI5ykY [video]<iframe width="560" height="315" src="https:...

Re: New owner of Hymac 580 B

New drive chain fitted. The old drive chain was pretty stretched out.
