I have a Shopsmith Mark VII purchased in 1964 that needs new belts. Can anyone tell me if the belts for the Mark V head will fit the old Mark VII head as well? If not is there a source for these belts? I'd hate to see this beast go to Shopsmith heaven because of such a simple problem.
Thanks

Re: Old Mark VII Parts Question
Although the Mark 5/V poly-v belt is narrower than the original Mark VII poly-v belt, it WILL work. Bandsaw Tire Warehouse has a belt made to Mark VII specs(wider) available on E-bay.
The motor belt is NOT the same as a Mark V/5 motor belt. However it is a 1/2" standard v-belt which I believe to be 30 1/2" long. I recommend a 'cogged' automotive belt. Since belts today are typically slightly narrower than the original belt the speed range is moved slightly upward.

Re: Old Mark VII Parts Question
I ended up using a 30" belt as 1/2 sizes are VERY hard to find.

Does the shorter belt change the speeds at all or is it just the belt width that affects it?cham-ed wrote:I ended up using a 30" belt as 1/2 sizes are VERY hard to find.

Re: Old Mark VII Parts Question
Yes it will move the speed range downward(the belt ends up further into the motor pulley for a given control sheave setting(speed dial)),luggw1 wrote:Does the shorter belt change the speeds at all or is it just the belt width that affects it?cham-ed wrote:I ended up using a 30" belt as 1/2 sizes are VERY hard to find.

A narrow belt does the opposite. It rides further into the idler puller AND also rides further OUT on the motor pulley.

Re: Old Mark VII Parts Question
Thanks for all the helpful info. I've purchased the appropriate belts. Now, I notice the Mark V belt comes with instructions for replacement if you buy it from Shopsmith. I know it's not a Mark VII head, but the assembly might be similar. Does anyone have a copy of those instructions they'd be willing to share digitally to help me figure out how to get that top belt replaced?
Thanks.
Bill Lugg
