Thank you for your help.
It is dual V-belt.
Ted says he has them and also provided cross reference to current parts.
We may get my friend's lathe fixed.
Having a lot of slip in high torque operations, i.e. drilling large holes, etc.
Tried retensioning the belts, but no real improvement. I suspect the problem is the Vari-Drive belt, rather than the spindle belts.
The original owner says they have never been replaced.
Either way, we will scuff up the pulleys, replace the belts, retension and giv'er a go..
Thanx and Good Shootin'
Well, I may have looked at the wrong part number.
I show the timing belt as PT4456TT1, but I believe that is the single drive belt on the post Nov 1974 up.
I don’t show the number you listed, does it have dual drive belts?
I looked in the older parts list, and the AC dual drive belts match the number you list, starting at about SN 73TT876.
That belt is 66.93-inches.
If anyone might have them it would be Ted…
The part numbers you list are for a November 1974 forward, starting about SN 74TT1260.
The variable speed belt is a Speed Selector Inc. belt # 2322V421
This belt is still listed in their belt catalog, but not sure with out calling.
I believe the variable speed belt is the same as the older 14’s before the above date.
The timing belt is a Browning 660H100
The timing belt is not the same as the older belt.
You should be able to cross the 660H100, I see them listed from 13.00 to 106.00
That belt is 66-inchs x 1-inch
I don’t know the length of the VSD belt, only that it is 10.5-inchs center to center.
The Speed Selector price list as of 4/22 lists the belt at 54.00.
Hope that helps,
Working that as a backup. I tried to find mfg and numbers on old belts but they are gone. Found a guy (TED PFLUGNER (latheman2@...) that says he might have them. Mostly I was hoping someone in the Forum had current P/N's. I will post results if I can source them.
Thanx and Good Shootin'
Do you have the original belts? Can you take measurements off them and look them up from there? I have a south bend fourteen though right now it’s in my son’s shop about 20 miles away. If you need measurements and ain’t in a hurry I might be able to measure them.
