Technical Belt for eng.

I have a 8cm with early w/p, a gen delete, and a left side gen, mount, but no gen. I would like to know what size belt I would need. 5/8 pulleys.


thanks,

jim

 

Even if someone has the exact same setup you have, their belt size probably won't work on your engine (Murphy's Law). Get a belt that's close, see how far off it is, get another that's closer, repeat until you get it right.

 

You are probably right. Just trying to save all the back and forth.

Thanks,

Take a piece of rope and estimate belt size. Then go shopping.

 

I have never been lucky the first trip to the auto store. Buy a couple sizes smaller and larger as the rope size and bring the unused back for a refund.

 

Go to the local farm store, buy one of their cheap shit belts that you know is too long, cut it in half and wrap it around the pulleys. Put the adjuster in the mid point, wrap the long end over the short end and mark the end with a crayon. Measure the outside of the belt from end to crayon mark. This is your length. 5/8 belts are called “B” width belts and Gates has all kinds of lengths. Example: B34 would be a 5/8” width belt of 34” length. PM me with a measurement and I’ll look in my Gates book for the belt, but I’m at work and my books are at home. Using the correct width belt for a measuring tool assures correct length because it rides where the belt would ride.

I have a collection of old belts, one 7/16" wide one that's really long, and I cut it as he said, and use it to measure for belts.

I don't have any extra 5/8" belts, though. So his idea to get a long cheap one to use as a starting point is a good one.

 

All good info.

Thanks,

I use electrical tape and wrap it abound all the pulleys on the outside of the pullyes do not pull or stretch the tape . Then lay it out and measure it. Make sure you put the adjustment near the lowest point or in the middle. I use gates numbers and order the belts on line they are the least expensive.

 

The rope trick works and it helps to have one of these. That way you can leave the rope at home and give them a size. This measuring tool is also a great help when replacing a worn belt when no numbers are visible.

About $30

 

Wouldn’t have a part number for that would ya?
