After or rather during my first outing in my " Back on the Road " Holiday Rambler 1987 I experienced loss of power sterring. My trip was short so it was just a pain in the a--.    I am not a mechanic but when I took the engine cover off I saw what I beleive to be the power sterring pump located at the top left of the front of the motor and there is no belt at all on the pulley .  Can I just look up the belt for a P-30 and order it ? Any advice would be very appreciated .  If I can repair it my self I need to.

dont know about that, but do know that if you take a piece of string and carefully route it like the belt would run in the pulley grooves, pulling it snugly and then cutting it when it completes the circle will get you within an inch of the actual belt. seldom do the parts house jockeys give me the correct belt first time anymore. :(

or your could go to an look up their add a link belt. you can get them in different widths so they should fit most applications(long as it requires a v belt). they come in 80 inch lengths so one should be enough for most uses. they are much more durable than a regular v belt and a godsend if you have a difficult or complicated routing. they are not cheap but are well worth the cost and should be in every toolbox.

if you have a chevy 454 you can start  at  autozones website and put in p30 that will bring up a belt close if not the belt, that has been a great source for us on the road ,another ref is a chevy truck k3500 in your year range.

yes and Phillip it's an easy repair too. You may get a little greasy and have to extend down into the engine bay, but at least you know it's done right.  Put it on, fire it up awhile, turn off engine and make sure it is "snug" but not bar tight and away you go.  May as well check fluids while your there.

Philip a word of caution if you use a string to measure your belt length check the amount of adjustment you have on the pump pulley. loosen the power steering pump adjustment bolt and position it so you will have adjustment either way. A string will give you a ballpark figure but it measures from the very bottom of the belt groove and a V-Belt does not travel in the bottom of the groove so a tight string will cause you to have a short belt. I don't want to discourage you from using the string method It does work just be prepared for it.  good luck

Thanks guys. It's a Chevy 454. I will use the string to measure and look it up . 

You should be able to get the right belt at your local auto parts store. I'm surprised you didn't lose your brakes as well - I would have thought that's a Hydroboost setup. 

Good morning, Phillip; 

There may be more than one V-belt on the power steering pump.  There is the one coming from the fan pulley to drive the power steering pump, the Gates 7812, and there may be a second one going to the air pump, which is either a Gates 7450 or a Gates 7460. 

If the problem is the belt going to the air pump, you have some time available to get the V-belt needed to put that one back into operation.  

Enjoy, and Happy Holidays;

Is the best way to change these belts from underneath ? I can't get up to the front of the engine with the engine cover off. 

I do not know about HRs, but on my Southwind all the belts have to be changed from underneath, there is no other way to get to them. It took a mechanic shop 8 1/2 hours to change the serpentine belt on our 454, of course they did include waiting for the new belt to come from 50 miles away. Just glad they found one and we did not have to sit the weekend waiting for one to be ordered in.

Well I will slide under there and have a look. I see if I can do it . I'm not a mechanic But I saw one once. 

That didn't take long. I can't fit under the front of the MH . Even without a creeper. OK . Off to the local Mechanic. Thanks for all your help gentlemen.
