Source for AC and PS Brackets

Hi all. Wednesday while driving our MH from Nevada City home to Dunsmuir the belt that drives the water pump broke.

I called Coachnet and they had the rig (1984 310 Classic Motorhome) towed to Jeff's Truck Service. While replacing the belt they discovered that the AC bracket bolts were broken off. In the process of extracting and replacing these, they have found that the AC bracket AND the Power Steering Pump bracket were broken.

They are having trouble finding replacements for these brackets.

They've checked with Chevy and their usual sources.

Where should I be looking for these?

Also, I am suspicious about why these brackets broke. Anyone have experience with this type of problem?

Does anyone know whether these parts are Chevy standard parts or Airstream special parts?

Guy,

Timely post. Just yesterday I bought a complete set of replacement A/C brackets for our Argosy. Cost was about $100 plus shipping for the whole set.

The power steering bracket should be the same on any 454 chevy 1-ton truck. The Pick-A-Part that I've been pulling parts from had plenty of them to choose from.

From what I've read and heard the A/C brackets have a tendency to break, unfortunately I don't now why. Can they repair the existing brackets?

I wonder if worn motor mounts might contribute to the problem?

I'll PM you the place I found the brackets.

Brad

Guy,

This might help you identify what you're looking for. Believe it or not I found that the 14100871 and 14100873 brackets might be available here in Pasadena.

guy99- adding up all that failed on yours it kind of sounds like the belt/s are not running true. i recently changed the wp & lower smog pump on our 345/454 and in doing so found many spacers of various sizes behind the brackets,needed to keep everything running true.just a heads up.
also we have 3 good sized wrecking yards in my area and if you are unable to find what you need locally contact me and i will check here for ya.
many of your previous posts have helped me to learn my 345,thanks.

Glad to hear that the power steering bracket should be easy. Wonder why this truck shop and the local Chevy dealer can't figure it out?

Thanks for info on the AC bracket and for the document, seems like it will be very helpful. How/where did you find it?

I think your motor mount idea has merit since the rig has been running for thousands of miles without burning belts and then suddenly it eats belts and breaks brackets. Something has to have changed and none of the related components have been worked on recently.

Guy,

Hopefully you won't throw the old a/c bracket away. From what people tell me they are rather scarce so possibly it could be repaired or copied someday.

Thanks. I have in the past had issues with belt alignment with consequent slipping and burning, etc. BUT the rig has run in the current configuration for many thousands of miles without problems, so, I'm assuming that one of the components failed from age, or something else is wrong which I hope will be apparent when all the broken bits are replaced and in operation.

Thanks for the offer to search the wrecking yards. I'm going to drive the 100 miles to the shop that has the rig tomorrow to examine the broken parts so I know what to look for. Hopefully I'll be able to find what I need, but I may have to call on you.

Thank you for saying that some of my posts have been helpful. I have derived much benefit from this site so I try to 'pay it forward'. Its nice to hear that I am somewhat successful.

Thanks,

Guy

Guy;
Just remembered that the PO of my moho gave me a box of extra motor parts. I recall seeing some accessory brackets in there. When he got the rig it did not have smog headers and he searched aroung for those, well any way I'm wondering if there may be a few different brackets, like for smog pump, alt, savvy

Not as simple as you'd think.

Yesterday I drove the 100 miles to where the MH is stranded. Empties the refer and gathered up belongings to bring home. Examined the brackets in question.

The AC bracket seems to be the one pictured in the document Brad posted, and his source says they have the bracket available. So it seems that I'll be able to get one.

As to the PS bracket. Seems like it should be easy to find, right, well maybe not.

I took the bracket to the only junk yard in Chico (Pick and Pull). No luck. There sure are a lot of different PS mounting brackets on Chevy V-8's but I couldn't find the one I need. So, I'm back to square one on that. Here are some (poor quality, but what do you expect from a phone) pictures of the bracket.

So if anyone has/sees one of these, ...

The other thing I hope to do is get a diagram and part number. Any ideas where I should look. I have a P-30 shop manual but it doesn't seem to picture any of the MH specific stuff.

And so the search goes on.

The quality is actually pretty good if you expand it.

Anyone know how to get a part number?
