I have two Nova G3 chucks. I know they have been needing to be cleaned for awhile. I have read so many horror stories about not being able to get them back together correctly that I have just kept putting it off. I looked at an instruction on how to do it and decided today was the day. Turns out I had nothing to fear. Speaking about the G3 chucks only, it was very simple to reassemble. I did both chucks and they work like new

It has been several years since I did mine, but like you, it was not much of a problem at all. While I hope this encourages others to do similar on their chucks and lathes. Some people have a natural ability that others do not, and some have learned almost like apprentices, it is good to find and read the instructions first.

I need to clean mine again!

For me; the bi-annual cleaning was an easy and welcomed chore. All went well and I was able to appreciate the craftsmanship of my Nova chucks. Clean tools was a delight.
 
montmill has the idea. My son is an ME and takes photos of any project that requires disassembly and assembly. I now do the same.
Recommendation: when I disassemble a pen, I put a bath towel on the workbench. Things are dropped, fly off in the air and have a habit of bouncing along with landing in hidden places. I plan on doing this when I work on the Supernova2 chuck.

Lay out the parts on the order removed and reverse to assemble. Did this with my M16 about 56 years ago.

This is what I do, and sometimes I take few picts on complicated spots. When working with circuit boards and wiring - its picts, and many. for smaller mechanicals, it is layouts in order with before and after picts.
 
The instructions say to apply a "generous amount of lubricant to all surfaces that come into contact with other parts"...

What lubricant is recommended for this? Grease? Silicone?

Good question. I would say a very light coat to prevent a buildup of dust and chips.

Because it was very easy to do, I did not apply any lubricant because I think it'll attract dust and build up. If it starts to feel tight, I'll disassemble and apply some sort of lubricant. They suggest WD40, but that's not really a lubricant. If I have to, I'll probably try dry lube.
 
No to Silicone! It messes up a lot of finishes and once you get it on a surface it keeps transferring to others. I haven't needed to clean mine yet but in the absence of a recommendation by Nova I would try a graphite or molybdenum based lubricant.
 
Thanks, Ken.
Hmm. Downloaded the pdf. Printed six pages according to the review screen. But six pages are : 1-7-8-9-10-11. Missing pages?
