Bridgeport BOSS 6 X-axis Belt

[split63]

Where can I find the X-axis belt for my Series I BOSS 6.0 CNC Rigid Ram Mill?
What's left of the belt seems to have 44 teeth.
THanks,

I have not had much luck find the belt for the X-axis, however it appears the the Z and Y axis have been replaced with goodyear betls. Here are the Goodyear part numbers

Z: 270H075
Y: 240H100 (48 tooth)

I decode this as (number of teeth/10)(H series)(Width in inches)

So this would meand that the X axis should be:

X: 220H100. (44 tooth)

I still don't know what the bridgeport part number is. The 6.0 machine went to the 2:1 pulley, so its a different belt than on the 5.0 and earlier machines.

Note also that the tooth spacing is 0.5" and the belt thickness, including a tooth is 0.16".


(UPDATE) After talking with Bridgport, they provided the following original part numbers:

X Axis belt: 11652116
Y Axis Belt: 11652117
X Axis Counter Belt: 11770271
