Disassembling a 6" Westcott chuck?

Question

A gunsmith friend of mine brought me one of the basis Westcott 3 jaw chucks..threaded back, that needs to come apart for cleaning.

There are 3 cap screws in the back, three in the front, and a single near the single wrench hole.

I pulled all the screws..and still the damned thing wont come apart..it appears that something to do with the wrench gear is holding the thing together. The back is loose and will move but the wrench gear is the pivot point of the movement. Everything appears to come out the backside of the chuck body.

Anyone ever popped one apart? They are common enough..shrug

Remove any fasteners, mount it up and spin it as fast as you can...it'll come apart!

According to Gunner :

I don't know that particular brand, but I have a question:

Are there three threaded holes in the backplate between the three holes from which you removed the screws which went through to the chuck body? If so, it may be intended that you use those just removed screws in the other holes to jack the backplate clear of the body. It is often a *very* tight fit on a well mounted chuck.

If so, the front bolts probably hold the retaining plate on behind the scroll plate -- once you get the backplate removed.

If not, I'm not sure what to suggest, since as I said, I've never handled one of those.

Good luck, DoN.
