Engine belts

Yes but you will need to remove the fan shroud.

Yes but you have to work the belts around the fan blades. There is usually one place where the fan shroud has a little bit of clearance so you can work the belt in over the blades without taking off the shroud. Just lean in over the top of the engine to do it.

Yes and in my experience you don't need to remove the shroud either.
You can work the belt around the fan one blade at a time until it's over and then you're good go go.

Some day I'll show up at a rally and show you how change belts without
moving the shroud or loosening any attachment like the A/C, alternator, or
power steering.
I tried to write up a description of the process many years ago but no one
seemed too excited..lol Before I discovered I had the alternator out of
alignment with the rest of the pulleys on one of my trips to NM, I changed
a total of 3 belts on the side of the road. One was supervised by a Trooper
who spent a lot of time scratching his head lol

After reading one of your postings here on the procedure, I decided to try it when I changed to 1/2" belts. It worked great.

Yep......been there, done that. Not fun. I did not remove the radiator or
shroud.

I'd love to meet the gent who designed the power steering adjustment.

Is it possible to replace the power steering and alternator belts without
removing the radiator?

No ONE PERSON designed the power steering pump and bracket assembly. It is
a mixture of pieces gleaned from the assembly line spare parts bin. It,
combined with the power window wiper hoses is a P.I.T.A. Don't ever take an
assembly off and leave it set for a couple of days. Pieces will wander off
searching for familiar friends. Finding none, they roll under work benches
and hide out, never to be found. (Grin)

How did the change to 1/2" belts go, and what mfg. and part #, if you
remember.

Thanks, RonC

Rather than rely on my memory (part number A56 comes to mind) for the Alternator belt(s). I have a double alternator belt and I have no PS belt. Let
me go search for the postings to make sure. I put them on 2 different coaches at the time and there is one spare set in one of the coaches now.
Unfortunately neither of the coaches are here for me to go look at.

Let me research it again.

Well, my memory still works sometimes. The alternator belt is an A56. NAPA is one source for it. I ordered ours from one of the two V-belt supply
places in Sioux Falls. This is an industrial number so brand does not matter. A56 says it is a 56" belt. The problem is the industrial belts are
measured ID and ours are measured OD. So an industrial belt of the same physical size will have slightly lower number A56 works great for the
alternator and is 58" OD.

I looked up the various part numbers listed for our coaches using OEM 7/16" belts.

The alternator translates to 7/16" by 57" to 57.5" inches and we know A56 works great here. So I say subtract 1 to 1.5 use that length number for the
A (industrial belt) size.

I have not figured out or installed the correct PS belt because I do not have any need for one. But this is what I think they should be it should be:

403 and 455 Alternator (I have only tested a 455).
7/16" X 57" to 57.5" use an A56

403 and 455 power steering.
7/16" x 42" use an A40 or A41

455 AC
7/16" X 62" use an A60 or A61

403 AC appears to be
7/16" 60.3" to 60.7" use an A59

If you have any doubts on the size + or - an inch, order them both. The most expensive belt listed above was around $3.50 down to around $2.35 each.

Then next time I order something from them I will throw an A61 on the order for my AC.

For more than a few years now, I have run and had no trouble with Gates XL Numbers:
11A1575 - 7619
11A1450 - 7570

Both of these are 11mm~15/32 belts, but they do not pass the 10mm wrench test because the profile is shaved at the shoulders. After a considerable
discussion with the Gates engineer that I still knew (according to my engine log this was about 10 years ago), I found out that these belts are
designed to have the correct pitch length, but not have the fabric ride on the sheave as this fabric would wear the sheave out. It seems he is
correct.

I run the dual on the alternator and wanted a pair of matched belts. Same guy told me not to bother as their process controls are now so good that
any pair of belts by the same number right off the line will be as close in pitch length as matched pairs used to be.
