Title: Need a fan assembly part
Post by: Tedsoldbus on June 13, 2022, 02:15:34 PM
Looking for a radiator fan assembly part. Hopefully the pictures will load. It is off a 1994 Prevost XL. My local shop is trying to get a young lady country singer back on the road after her bus was parked for 3 years due to the Covid shut down. The part number is S M126-M20 and she has an 8V92.
Already sent this and bus serial number to Luke and Jean Ruel in Quebec to see what they can do, but thought one of you might have one laying under the workbench. Calls to 3 Prevost places said "Nope".

I took those pictures with my camera instead of phone and they STILL came out sideways! That used to work! Not that important. Anyone got one?

Why not try contacting the manufacturer listed on the tag?? Prevost merely buys parts from other vendors they don't manufacture stuff like this. Seal Master will no doubt be able to help you and should have the parts they sell to Prevost in a database. Maybe you can find a usable replacement equivalent to this exact part, it's essentially just a pillow block with a Zerk fitting, how hard can that be really. Maybe you could upgrade it to one that has real sealed bearings at each end, and do away with the Zerk and need for lubrication, entirely.

A guy I know had similar trouble with a Crown and the fan hub was worn and about to come out of the bus. He found a shop who managed to upgrade him into a pair of sealed bearings at each end and no further Zerk lube needed. Easy-Peasy fix. Don't Fall into the trap that everything a bus manufacturer uses has to come from them only. Or that you can't come up with a better way of doing the job. They have to think about costs for production to make a profit, you don't, and can usually find a better solution to what, in this case, is a simple shaft supporting pillow block used in countless industrial applications. You can make lots of upgrades to the stock production parts and improve your bus and reliability in the process. Look around.

I had the same trouble myself many years ago with the radiator 90 degree fan drive miter gear box on my Scenicruiser. Turns out it was a fairly standard Ohio Gear product used in many industrial applications. I found a new one from a local gear and bearing supply house that was massively cheaper than from any "bus part" supplier, and it fit exactly perfect.

Same thing when a driver shattered the Spicer 4spd on that Scenicruiser. MCI wanted $3500 for a replacement transmission (they were used in the MC7's and 8's too). I looked around in my local friendly transmission repair shops and found one as a take out from a truck for less then $500. It even had a slightly better gear ratio split making it a tad nicer to drive the 'Cruiser. 

There doesn't have to be anything magical about getting parts from the Manufacturer in some area's of a bus. Be open minded and think outside of the box. Scrap yards, Industrial Parts houses, places like this are always good to look into before despairing. Good Luck

Prevost tells you who the manufacture of the part is in their parts books so does the old GM bus parts manual,lol now Eagle and MCI have their own magic part numbers

Great advice! Seems so obvious... now. The shop where the bus sits works on only Prevost and sees very few older buses, but remembered mine is 1980 and thought I might have ideas. Thank you gents! Will be on the phone when the sun gets a bit higher in the sky.

They do this for car parts. It would be an awesome project if a bus nut wanted to create a full interchange database for all bus parts. any volunteers?

Luke has it already lol but he is tight lip with names and numbers too that is why he repackages parts before he ships the parts and there is nothing wrong with the practice they all do it

Thanks Bob. Gene Ruel said it is Prevost part 550601, a "pillow block" and they don't carry it anymore. will ask him about the number you gave me. Talked to a couple of numbers at sealmaster. They are looking for the old guy that still has the old catalog to get back to me since their own part number does not come up in the computer. Me thinketh Luke will beat me to it, but that is why we love him. If he finds it, he wins. Still working it. Grainger is a sealmaster distributor and I know a guy there that is looking as well. Wish I could hand it to you. You would stare at it and rebuild it with an old part off your tractor that lasts 100 years. Thanks again for the great time up your way.

Just replace with a Timken pillow block easy to find and not a rocket science ,I think it was a V lock or SAF style TImken I used before

I know Van,
Others have had the same valid question. The shop doing it only does Prevost but sees very few older ones. (I think they do me because they like seeing a 35 footer pull in there once a year. And the owner is a retired Marine). He does newer stuff. All 60 series and newer. He is always slammed with about 15 to 18 buses in the yard and others begging to come. Half of what is there is awaiting parts. They have chased this bearing about all they can (or want to) and thought I might know some older bus parts guys. They fix some pretty tricky stuff but have had difficulty with parts for this bearing out of a 94 Prevost. They don't use or even know of Luke or Gene Ruel because they don't need that kind of stuff very often. I told them I'd take a run at it. Just feel sorry for the young lady country singer that was doing well until Covid. She can book concerts if she can get there. I'm getting closer. Still bet Luke beats me to it....  I have a BCM member that offline told me he can rebuild it if I mail him the housing, but not for a while.
It is just kind of fun to chase it. Too hot to be outside.....
