How do I remove the chuck backplate on Craftex CX708

[19shaun79]

Hi All,

I upgraded from a Chinese mini lathe to a bigger Chinese lathe - a Craftex CX708 10x18. I love it!

I am very green. I am learning by practicing and asking questions.

I bought a 6" 4 jaw chuck. It doesn't fit directly on the lathe, so I figured I needed to purchase a new backplate.

How do I get the original backplate off of the lathe??? In the last picture, you can see the piece I am referring to. In the third picture, I am showing the flange that is loose because I removed the three allen bolts that are holding it on.

The first two pictures are of the new chuck and the new backplate I purchased.

Looking at the lathe's manual (which is pretty shoddy), I may have to remove a flange nut on the gear side of the headstock?

Please help,
TIA!

Shaun

Nobody who has one has chimed in yet.

So, I'll get you started with what I remember. There should be three screws on the back of the backplate that need to be removed. Then soak the interface with penetrating oil overnight. In the morning you can apply gentle heat to the backplate only and then some love taps all the way around with a rubber mallet. It should come off.

The main thing is penetrating oil overnight. That gives guys who actually have your lathe the time to vomit on what I said without doing any harm. Maybe wait with the mallet......

I don't think the backplate comes off.

I'm not familiar with the lathe but looked up the manual here

Just to clarify, when you say 'original backplate' you mean the highlighted plate on part 49, the spindle, which appears to be fully integrated into the spindle shaft itself?
