Master 2500 belt help

[mike os]

Does anyone have information on the belt that drives the lubrication pump?

The belt that's absolutely shredded looks like it was once about 1/2 inch round, and 630 long ... .. no info on it at all

Boss thinks its a v belt, I'm not convinced

There is a manual here but I do not know if it is the correct era.

Colchester Lathe Co., Ltd. - Publication Reprints - Colchester Master 2500 Manual and parts list | VintageMachinery.org

On p.44, it gives B345-5011 for the belt. The B345 bit is a genuine reference to a B-section belt but I am not sure what the 5011 bit is nor does the length tie up with your dimension above.

Edit:

B345-5011 is the Colchester part number. 73924-0 is the Clausing part number, neither of which give any clue to the actual belt spec., sorry.

630 long. I'll have a look for you through our spares.
