Fan Belt Sizes

[farleyjd400]

Anybody know the correct fan belt sizes, or where i can look them up? I would like to replace the fan belts on all my machines. I know parts reloaded sells new belts but im not sure what size to get.
Machines i have are,
1973 JDX8
1974 JDX4 special
1974 JDX6
1972 400

Thank you

I was trying to find the right size for your 400, but I guess it's also serial number dependent.

I looked it up in the parts manual but all I found was the product number, no sizes. I bought one two years ago for my 72 400 but I can't find for the life of me what it was. I think I got it on eBay.

these are the numbers and sizes that I have used to get new fan belts for my sleds. these numbers are from (TCI) trans can imports.

I use these numbers to order belts as a reference I have not ordered from TCI personally. I mostly order from MFG supply or dennis kirk or my local sled shop I find that his belts are of better quality (Gates brand) this is not a place to go cheap not a east trail side repair.

I hope this helps. If any one has a better list or a update on using a size from this list with personal experiance pls post your thoughts tks
