So, the jackshaft bearings (?) went out on the [old] Swiss.
This shaft transfers power from the main spindle to the guide bushing.
So I tore it apart, and the bearings themselves were actually just fine, but ... they were loose on the "shaft".
???
So as I git it all apart, and trying to decipher exactly what it is that I am looking at, I realize that the bearings were running on a split bushing, behind some oversized threads.
??? This is a strange set-up to say the least. ???
Trying to understand why it is that they would have built it that way, and I'm just not seeing it ...
After some time I come up with this idea:
Well, could this be a repair?
Yunnow what? I think it might be!
It looks like maybe the "shaft" may have wore down, and maybe that surface was cleaned up, and then a split bushing made to fill the gap.
Could that be?
If so, that's a pretty slick repair and likely saved a bunch in downtime and parts costs!
(if part even available anymore)
OK, so - the bearings are actually OK, so it just looks like it needs a new bushing made...
It's lasted
this long, so I guess it's a viable repair...
... and the more that I look at it, the more deja'vu' I am getting....
Yunnow, I think that I am the "they" that repaired this before and made that split bushing originally....
New bush in and bearings pressed on.
Although, they seem kind'a tight, so we'll see if they last or not?
I have it running @ 750rpm while I am eating dinner...
Y'ever run into repairs that you obviously did at some time, but don't remember them?
I am living that reality more and more these days.
Not exactly sure what that means tho?
