South Bend Fourteen Lathe Drive Belts
|
Mark R. Jonkman
The south bend fourteen doesn’t use flat belts. It has a Reeves drive for variable speed and a main drive belt that I believe is like a timing belt on mine.

Don't know about your area , but I found a company
that makes belting one day when I was in Reno . They clipped up my
belt that I bought at Tandy leather & also made me a composite belt for $10.00 for my SB 9A lathe . Check in your phone book if you can find one or do a google for industrial belting in your area . animal On 7/19/2022 3:54 PM, Andrei wrote:

Have you considered a linkbelt for a v-pulley? Better power transmission and lower noise.
Otherwise, for flat belts there are a bunch of ebay seller who make custom lengths, either skived or wire fastened.

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..

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,
Steve

Helping a friend with his lathe.
I found Owner Manual, Parts List and Maintenance Manual on web.
Looking for Drive Belts P/N PT8747TT2 and Variable Speed Belt P/N PT8756TT1.
Tried searching and cross referencing, but the South Bend Part Numbers are a dead end. South Bend can't help. Can anyone assist? |
