goutoe · April 05, 2012, 09:12:46 AM

Hey guys I could use some help. when I bought my bus about 1/4 of the bottom of my fan shroud was missing, the engine does not run hot because of this, but I am concerned about road debris hitting the fan I have thought about making some repairs to the shroud with either metal or plastic but I would prefer replacing the shroud. does anyone know of an after market supplier? or any repair Ideas? My bus is a 1977 AM general 6v92T Thanks. John.

I can't say I've heard of any after market suppliers for shrouds, but that doesn't mean they aren't out there.

Might check with the local transit and see if they might have a lead. Or find a transit that is or has run the AM Generals and see if they have any laying around or can tell you where to get them.

Or you might check with TomC and see if he has one I believe he upgraded his to a larger radiator when he turbo charged his.

Thanks Bk . for your input I guess my answer is to repair my broken shroud and get on with it, its not a big deal just wish I could have found a new one, thank you so much for your input.

Haunt the bus scrap yards.

Fan diameter, radiator dimensions, depth of shroud.

You might get lucky and get something you can cut down to fit?

You know where the fan blade should run in relation to the edge of the shroud?

happy coaching!

Thank you Bus warrior that is good advice, I have thought of salvage yards not sure of where to start though? I was pleased with my bus mostly because there were no belts! Seemed like a bonus to me. I guess at this point I will try to figure out my shroud problem and find the best solution thanks again for your help.

I should have said "heavy vehicle" scrap yards

Lots of shrouds in medium and heavy duty trucks that will come close to what you need.

happy coaching!

Thanks again Bus warrior, I will try heavy vehicle salvage yards although in my expierience the plastic parts are the first to fail, I have thought about my options maybee a plastic fix might be the best?

Throw it out and make one from metal. I did that for my Eagle. Hear are some pictures.

Thanks for the info David, I think I have enough of the old shroud left to make a pretty decent pattern, I will try to get a machine shop to cut and bend the steel then I will weld it. good pics great advice! Thanks John.

The other option is to fiberglass the existing parts and at the same time, form the rest of the shroud with fiberglass mat. I did that with mine and it worked great. That said, only about 10-15% of mine was missing.

I can't tell from David's photos, but it looks like the sheet metal is flat against the radiator rather than tapered to the circular opening. Forming the sheet metal to replicate the cone shape of the shroud will require some good fabrication skills.

Jim,
The metal is flat, no cone shape. The 1" strap welded around the hole replicates the old OEM shroud opening, but I could not duplicate the tapered, conical shape of the OEM plastic shroud. However, if you remember all my cooling issues back then, everything was remedied when I bought that new fan as shown in those old pictures. Haven't had a cooling problem since, in any situation. I'm still running the original 6v92 going on 12 years now and about 65k miles.

David, I have mentioned your fan solution to your heating problem to several folks. Only problem is, I don't have the details of your fan selection. If you have those details, would you mind posting them here and I will try to capture them better this time.
