Well I picked up a couple of the 52" fan belts from Mac's AutoParts(pkg says 53" and actual is 52.5") on the weekend. I went to instal them today and they wont fit. Even with the generator all the way down I can't even get them to go on. The next size up is 55" which i think will fit just fine.

Im not sure why my engine is different since its now inline with the specs for the carrier engines?

Having worked in the spare parts industry, I can tell you that belt sizing is enough to drive you totally off the rails!
Each manufacturer will measure their belts differently, and I have seen differences of 25mm (1 inch) in belts. Trying to understand it will dement you...

When you do get a belt that fits, write down the size AND BRAND for future reference.

Strangely B 52 also fits a 261 Chev engine.....

Due to manufacturing differences and then pulley modifications to match groove size and substitution of a smaller pulley alternator for the original generator..... this is what I have opted for...... works every time.

I purchased a 6 foot lenght of special linked belt in 1/2 inch size. These are usually available in wood working store.... claims it will reduce vibration on table saws and other motor driven tools. Each link can be dismanteld with needle nose pliers and adjusted for lenght by the inch.

You simply fabricate the proper lenght that will fit your engine set up.... take it apart and run to the nearest tractor dealer to match the size and proper width..........

Also comes in handy when you need to replace a fan belt on a old Allis Chalmers tractor that requires removing the rad hose ( and draining the rad).
You simply assemble the links with the belt in place.

Caution.... it sells for about 9$ a foot but can be reused over and over again.

Hi Bob

Thanks for mentioning this approach to coming up with a correct belt length. The $10 a foot cost isn't to bad if you figure in how many trips to the parts source you can save. The adjustable belt is a great little invention not a new one been around for long time, here is a link to the installation instructions for one type http://www.fennerdrives.com/assets/ptpinstall.pdf. Here is their main web address http://www.fennerdrives.com/ here is the link to their Catalog http://www.fennerdrives.com/catalogs/hpcvbelt.pdf picked this company as they had better pictures of the belt, no other reason. In looking I did find that Harbor Freight has it listed http://www.harborfreight.com/vibrati...elt-43771.html for $25 for 5 feet but it is on back order.

Given how hard it is to install a fan belt on Chevy CMPs because of limited access and the close spacing of the fan to the radiator, having a length of this in your "end of the world" spare parts box in the truck might not be a bad idea.

Oh and thanks for giving me the topic for this months Tech Tips in our MV Club Newsletter.

Cheers Phil

Phil,

The Fenner belts are excellent, worth using, we have one on a haybine that means we didnt have to remove the wobble box. New Holland dealer was gobsmacked.
