A used I&T shop manual says it is so. *sigh*) This dang tractor of my FIL"s going to drive me back to drinking. [Reply]   [No Email]

He is not asking how get his fan belt off. He is asking about replacing his generator belt, if it is to short like the belt on a SWD9 or a 600 diesel to go over the fan one blade at a time, then yes you have pull the radiator to get fan off so you can change the belt.

I have used this link belt for years, they wear better than a conventional belt. It's so easy to replace a belt, as they split with nothing more than a needle nose pliars. Easy to find the right length for an alternator conversion, just add or remove links until it is right. These belts are avalible in 10 ft rolls at most bearings and drives shops.

The other end of the baling wire, you attach to one of the frame rails or other stationary object. Next, with the set screw loosened, use a hammer and hard piece of wood, like an old hammer or ax handle, to strike the raised lugs on the sheeve. By hitting the hard wood, and not hitting the sheeve directly, you provide a cushion that protects the sheeve from breaking. It worked for me. [Reply]  [No Email]

I have a SWD9 & a 600 diesel and to change the generator belt you have to pull the radiator becouse the belt is to short to go over the fan blades one at a time. So to change the belt you have remove the fan, to remove the fan you have to remove the radiator. Mite be the same thing on a 450 if it's a diesel. Good luck. [Reply]  [No Email]

Don't "whale" on it though. Just loosen/remove the set screw, and use a hammer and screwdriver and TAP to drive it around. Usually the threads are just crudded up with caked-on grease and dirt, not rusted. Wire brush and PB blaster the threads will help things move along. [Reply]  [No Email]

Seems like some guys say to use lots of PB Blaster and heat to free it up. [Reply]  [No Email]

Just loosen the pulley sheave fully and slip the belt over 1 fan blade at a time. Ditto for the generator (alternator) belt. [Reply]  [No Email]

Getting that set screw out was the worst part. wd 40, torch, hammer,screwdriver, and patience. It ended up not being as bad as it first looked, but it wasn't the best time I ever had in my life.

You will need to completely loosen the adjustment sheave for the fan belt. The generator belt can then be slipped under the fan belt and you should be able to move it over one fan blade at a time.
