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.

The Splines on the drivewheel is pretty worn at the edge causing the clearance. Now the problem is, how to fix it?

Re: New owner of Hymac 580 B
If it were mine and I couldnt get the parts I would build the surfaces up with weld and machine it back to the correct size
Im not sure if you have the facilities at hand for such things but machine shops arent very dear for this type of thing in Australia

Yes Paul those were my thoughts too; I have pm'd Andy as I may know the whereabouts of a good second hand one but I will have to confirm this first, to be fair assuming I cannot find the good used one, then once the old sprocket has been welded up it would need an engineering company with a decent slotting machine and lathe to carry out the repair.

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 with loctite 660. Maybe i go for that. But right now Jeremy made me curious..

Re: New owner of Hymac 580 B
I wouldnt even bother trying to machine it my self but would weld it up and then get it machine from some pretty switched on people as any movement left would return you back to were you are now
Even shimming I would think would be only a stop gap measure until a job is finished and can be fixed properly
but thats just me and experience has taught me that although the initial cost can be large on some of these repairs Im better to fix things right and do it once even if it stretches me financially quite a bit it is well worth it as the machine is now ready to make me a dollar

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.

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
Perhaps not a bad idea there Andy will have to see how it stands up to use however it's not like the machine is going to be used full time on a construction site, the only other repair method would have been to weld up the worn sprocket then have the teeth cut by slotting.
