Bringing a neglected machine back to life (Juki LU-563)

[MikeG]

Got a great deal on a Juki LU-563.  Essentially a one-owner machine that has spent the last 10-15 years in storage.  It is tight and free, but it will obviously need to be oiled and checked out before being put into use.

Most of the discussions on this forum seem to deal with damaged or broken machines.  This one appears to be in remarkably good condition.

My question is:  Does the machine need to be completely disassembled?  I have not yet found a service manual, and I'm hoping not to have to take it apart using a parts diagram.

Thanks in advance for thoughts on how to proceed.

Well, the good news is that you probably don't have to take it all apart. and you might just be able to oil it and go.  Some pictures would help us to to evaluate it.  Maybe a video walk around.

Do you have the whole machine, table,motor and all? Or just a head unit?

For starters, I'd oil it everywhere metal moves against metal. All the oiling points on top, everyplace underneath that a bushing, bearing or anything else moves metal on metal.  Turn it over by hand and let it sit for a day.  If you have the whole setup, motor and all try running it and give it a listen.

When I got my first industrial, it turned over a lot harder than any domestic i had worked with. I had no idea how tight it should have been so I erred way on the side of caution and flushed PB Blaster through everything followed by sewing machine oil. Turned it endlessly by hand trying to decide if it was too tight. I removed the internal belt so I could evaluate the top and bottom separately. After a week or so of this activity, turned out it was fine to begin with.
