1991 F53 v belt replacement

I am going to replace the v belts on my 1992 HR1000 Holiday Rambler with a 91 F53 chassis. I do not have a manual and am trying to figure out how to do this. From what I can determine so far there are two v belts one that goes around the ac, powersteering, auto tensioner, and fan, the other goes around the alternator the fan and something else. I cant find an auto tensioner of any sort on the alternator side, so my thought is that I have to move the alternator, however, I have never done this and am not positive if this is in fact what I do, and if so which bolts will loosen, and then is there anything I need to consider when moving the alternator as to not cause any problems with the belt alignment or reinstating the proper tension. I ordered the same belt to replace it, Gates KO60505.

I also have a question about the other belt, I can figure out how to remove it and reinstall it no problem as it has an auto tensioner, I can just slacken to remove the belt, however, my concern is that the belt number that is on there is the Gates KO60594, however, every place I look ie Oreileys and RockAuto has KO60685, I figured maybe it was an older belt or something, but the 594 belt is 60" and the 685 belt is 69". Im not familiar enough with putting on belts to know, but that that seems like too much of a difference. It seems like if someone wanted to tighten things up they might put on a belt that is an inch or two smaller, but like I said, I really dont know. Any thoughts?


Thanks,

Paul

Loosening the Alt is no problem. If you look at it closely, you'll see one bolt is actually a pivot. Losen this slightly, then loosen the other bolt enough to move. Tighten both when done. As to the belt size, there was prolly an Air Pump that was removed, thus the shorter belt. Replace with the same thats on there.

Ok, yeah I think I will order the same belt that's on there. I actually got a Chiltons for 1989-91 full size vans e150 e350 and motorhome chassis last night and the thing I didn't recognize on the alternator side is an air pump. Yeah I'm not sure why the belt on ac ps side is 9" shorter, everything appears to be there but it seems like someone must have changed something at some point.

Thanks,

Paul

Midniteoyl, do you know how to get the belt off and on the other side as well. The alternator side turned out to be pretty straight forward, but the ac ps side is giving me trouble. I thought I could just pull back on the tensioner and slip the belt in, but the tensioner pully wont move for the life of me. I thought maybe I should loosen it, and end up taking the pully wheel off and got the old belt off, but now Im trying to put the new belt in there and the pully still wont budge at all. There doesnt seem a place for it to move. There is a bolt on the back of the apparatus that holds the pullly wheel, but no extra slot to insert a socket to move it, and it doesnt seem to want to move when I tighten the pully wheel all the way and yank on that either any Ideas of what Im supposed to do to get the belt on that side.

Thanks,

Paul

Is this the kind you have? you didnt actually state the engine you have, so i am assuming a GM 454...




If you look at the pic, it gives the way to turn. I have been able to do it with a socket on the pulley bolt before, but usually I simply use a crowbar. they can be a real pain.

He said it is an F53 (Ford) and being a '91 would be the 460 (7.5).

If I remember right there should be a spot on the idler pulley to put a breaker bar on it to turn it to relieve the presure to remove and install. Any book should show how to do it. 460s(7.5s) have not changed in years.

:-) yep its a 7.5L 460 8 cylinder gas engine. I tried to embed the image or the tensioner pully assembly from O'reilleys on this post, not sure if it worked...but yeah I got the Chiltons manual that includes the MH F53 chassis, but it has no indication of how to loosen the tensioner.... there didnt seem to be any place to make it slack up on the tensioner. Its kind of funny actually in chiltons, on many of the other engine types it has an arrow pointing, or some dialogue saying this is how you slacken the tensioner, and on the 7.5 8 cyl it just has " tensioner" next to the diagram, Im like, yes indeed, that is a tensioner.lol. I ended up just taking the back bolt off and removed the whole assembly, then got the belt in place, reattached the tensioner assembly, tightened it a little, then held down the pully with a 1" wrench to put what I thought was an appropriate tension, and then continued to tighten the bolt on the back of the whole assembly....I need to buy a torque wrench....But it felt good and taught and when I started it up, It sounded wonderful.... no more nasty squealing sound.
