What Is & How Do You set proper fan belt tension?

Postby Deere John » Tue May 15, 2007 9:33 am

Hi, guys.

I did a site search for this and came up with a couple pages of mower deck belt info. Does anyone know what the proper tension is for the fan belt and the generator belt on the Cub and how do you measure such? I have a '47.

I used a bar to (gently) push up on the assembly while my assistant tightened the set nut. It was pretty taught, but I don't want it too tight for fear of prematurely wearing out the bearing.

Thank you for any help with this or point me to a previous post that addressed it!

Page 27 of the owner's manual. The fan belt should have 3/4" to 1" slack - meaning that you should be able to deflect the belt that distance midway between the pulleys. You should also be able to deflect the generator belt 1/4".

If you can't fix it with a hammer, you've got an electrical problem.

You should not turn the nut. Turn the shaft to tighten it. Turning the nut is a good way to break the front cover. Details in the Owner's Manual.

Thank you, gentlemen! My computer won't open the link for some reason.

jim, I meant the shaft. The nut sets in the little track that keeps it from spinning. The shaft has the bolt head on it that you turn to tighten. I think we're on the same page? If I'm doing it wrong, please let me know!

Thank you for all of your help! And it's time to buy a manual...

You'll need to cut and paste the link. Or use this one:

Yes, that is the right way to do it.

I just realized what the problem with the link is. It is that peksy ['] apostrophe that the phpBBS software no longer recognizes. If one substitutes %27 for an apostrophe in the url, then the links will work. Cub-22 Owner's Manual 1950, Page 27

All of the manuals are on the Cub Manual Server in the Welcome Wagon text above, and allof those links work because the %27 problem has been addressed in that text.

Unfortunately I simply do not have the time nor the energy to turn around an fix over 2 gigs of data simply because some programmer over at phpBBS was unable to write the code correctly... (sorry, but I realy cannot abide lousy code.. it is a symptom of instantaneous gratification and is a prime reason why Windows doesn't work very well)

I NEVER put a special character in a file/path/URL name, just one dot before the extension. It is an open invitation to trouble, sort of like using copper tubing to make a gas line or stepping off a curb without looking because you have the green light.

A guy I help once in a while on a web site recently took a whole server down by using some image files with a space in the file name. I don't know what the server was or what software it was running.
