Clausing 5400 drive belt removal

I need to disassemble my Clausing 5449 lathe to get it downstairs
into the shop. The 5449 is a 1968 vintage 5400 series with variable
speed drive and clutch.
To remove the lathe bed from the cabinet, I have to take off the
3 spindle drive belts. The manual tells how to adjust the tension
for those belts, but not how to remove or replace them.
Is anybody familiar with the procedure for removing the belts on
this machine? I don't want to disassemble the entire countershaft
if I can avoid it.
Thanks.

If you want minimum hassle, cut the belts and replace them with Fenner PowerTwist Plus and have a smoother running lathe.

It's an interesting idea -- though the reeves drive is a lot rougher and noisier than the spindle drive. The powertwist belts are well-recommended and it could save me a lot of trouble.
I'd still like to know the recommended procedure for belt replacement in any case!

According to Mike Berger :
Well ... I've got a 5418, not variable speed, but still those three belts in parallel from the countershaft to the spindle cone pulley.
You'll have to remove both the spindle and the back gear (actually underneath gear) from the headstock to do it.
The next section of the manual (if yours is like mine) is:
How to Remove Headstock Spindle
And after the "Re-Assembling the Headstock Spindle" you will find the:
How to remove back gears
Once you have done this, you can lift the headstock clear. It is secured by four bolts through two clamp bars from the bottom. It will also probably have a taper pin through the front lip of the headstock casting into the near ways rail, to assure precise repeating of the position.
At least you won't also have to remove the countershaft to actually *change* the belts for what you are doing.
Good Luck, DoN.

If anybody else needs to do it:
Remove the back panel and loosen the two jack screws in the cross ties to reduce the belt tension. Remove the 4 hex screws from the bearing caps for the countershaft and remove the caps. The countershaft can be pulled out the slid away from the belts.

My manual doesn't have those parts. I didn't see any missing pages but it might have been superceded by a later one. Thanks! It was actually easier to remove the belts by removing the countershaft, but it's nice to know how the other end will look when I get to it.

According to Mike Berger :
I'm quoting from the manual which I got from Clausing -- matched to the serial number of my lathe. You should be able to get one as well, and it covers not just what you have but related ones.
But for quick-and-dirty, you could download mine:

It is made from a scanning, so it is very slow to display, but high resolution.
Enjoy, DoN.

Thanks for putting that on-line! I have the original manual that came with the lathe, but it may be missing some pages -- or may have been updated later.
