Re: Fan pulley wont adjust down

Gerrard,
Try this too: grab a 15/16" socket and 1/2" drive ratchet. Place that 15/16" socket on the nut securing the larger pulley. With one of your hands, place the belt in the lower pulley groove and try to start the belt in to the upper pulley groove... hold this position. Now, try turning the lower pulley with your ratchet/socket assembly. You can walk that belt right into its groove.

I gotta go to work in a few till about 7:00 ( got some strange work hrs. semi-retired on my own terms) but I can try and prolly accomplish that.
See at this point as in last set of pics I can prolly manage to force that belt on either by your method or by tilting the shroud but wonder about forcing the shroud back up into place w/the tight belt on it.
As in last pic I thought right there I could take a big 1/2" thick flat screw driver and pry the belt on the top pulley right then but Im concerned what I would really have then? Abelt so tight it will wear-out the new bearings and new shaft as well in a yr or so?
I at least wanna get a softer belt while Im out today ( I work right next door to a huge Rual King ! ) like a non-Kevlar type because I want whatever belt that goes on it to stretch approx 3/4" hopefully in no time at all hardly.
Well Im gonna be late, will report back about 7:00 or so what happens.
Later All
And thank everyone for all the advise and coaching!

Re: Fan pulley wont adjust down

I have found when installing a v-belt,the "right" way to get one on that is really tight,is to put it on the smaller pulleys first,then start it on the largest one,and use a wrench to turn the pulley,while you hold the belt from slipping out of the sheave, and it will go on unless it is way too short..(Fireant 911 above described pretty much the same thing )..

You'd think it would be easier to put the belt on the biggest pulley first,then pry it onto the smaller one,but it doesn't work that way..

I don't see why a kevlar belt wouldn't be ok to use on a water pump,though they are a much stiffer and less stretchy construction ,and in your case one might not be flexible enough to stretch over the pulleys..you only need kevlar on a "clutching" application,most everything else you can just use a "fractional HP" type belt or an automotive one,but be aware automotive belts usually are not 1/2" ,they are 15/32"
and may be a different taper than industrial belts..

Thanks TractorHolic, I may have tried that but maybe not because I just tried everything and it wound up being about a mess lol!
I'll explain below so all the posters can read it. But I will do it that way when I get back on it.

Re: Fan pulley wont adjust down

Well I got on it after I got home a cpl hrs. ago and I got a diff belt on the way home just incase, its a 1/2" x 32" regular belt. They had some blueish ones but they didnt say kevlar anywhere on them and I was gonna get one of them but the belts were so messed-up none of them were hanging where the size of them was supposed to be.
Anyhow I got the 32" on there pretty easy, to easy really so I thought I would raise the top pully to tighten it but I also tried bending the shroud down after almost removing the nuts that hold it on and it was getting closer and closer and I was worried about bending it ( this is w/the Kev belt BTW) and I loosened the nuts that hold shroud on and pulled some more and all of a sudden " KA-POW!" and the whole pulley and fan assy seemed like went down altho it looked like it was already down all the way already?
So that was all loose so I had to remove it all again and thought I would raise it a little so the 32" belt would be tight enough , and of course the bearings came out and all that so I managed to at least get it all back together but the 32" belt is now to loose altho it all works by hand as in turn the bottom pully and the small upper one turns and fan does to and I get the mag-snap but it is still to loose.
Im off wed. ( cant spell it lol) so Im gonna get on it till I get one of them on right.
Everything turns out to be a big deal.
Here's some pics

Again I have no idea why the pics are sideways, when I pick them from my computer they are downloaded onto they are right-side-up so it happens on their way to this forum.
It took me forever to find them because they are already going into the 10 th. month. I guess my laptop is on California time zone or something,

Re: Fan pulley wont adjust down

BTW, The cheap belt that cost $4.00 & change goes into the grooves on the pulley's but the Kevlar belt is wider and seems to just ride on the pulley's instead if in them.
For what thats worth, but I'd rather the belt go in the grooves a bit.
I also am concerned about the 'sweet spot' meaning pulley & fan assy being tight enuf to stay put but not to tight for the fan not to turn or snap something. I guess thats just a experience call.

Re: Fan pulley wont adjust down

I was just starting to start messin w/my belt/fan shroud then I realized I'd better adjust my valves while I could still get to them easily without the bent screw driver and all that jazz.

Re: Fan pulley wont adjust down

Maybe the kevlar belt was put in the wrong sleeve and was a 5L instead of a 4L? All the ones I've used were the same width as the non-Kevlar ones, and rode in the pulleys fine.

When I got the non-Kevlar belt the other day the belts were so messed up I about said "heck with it" and just left but I made myself stay but I was tired from work but for the Kevlar belt there aint no "in the pulley's" about it, just kinda rides with it it seems.
With all the trouble I have with everything exept cleaning and painting Im just gonna get away from the Kevlar belts.
Thanks

Re: Fan pulley wont adjust down

Well I got that on and it took an entire 5 mins or less, its the 31" Kevlar belt just because it was the 31" one I had and that was what it called for.
I'll never understand how I can try something for days w/nothing but failure and then just say "Im gonna go put that belt on" and SHAZZAM! it goes on like I worked on a assembly line putting them on all day.
Go figure.
Oh yea the fan spins freely without hitting anything to.

And as most of the time the pix go sideways from my pic gallery to the article.

In my case is I get tore up pretty fast and after something doesn't work a few times I just become a wreck mentally and I should just walk away from it for awhile but I seem to dig in deeper and make things worse.
And if it gets to bad things start to break lol.
