You're probably going to have to provide more info. Photos would help. Is that any mounting surface on the hub of the fan? How about number of blades, material the blades are made from? Distance between holes on the hub? Type of bus and engine? Any mods to bus or engine since it was built (different type or engine, etc.?)

As the copilot aka wife it's my job to figure out how to post pictures. After much puzzling I'm asking for help please:-) we're working off a tablet and have been unable to get an attachment to post. Thank you for any technical help.

That is a unusual fan that size with only 4 bolts must be low HP with very little pitch

What is the vehicle, engine size, gas or diesel. Can probably give you some sources then.

I recently had Multi-Wing make me a new 9-blade composite 26" fan, and QCC made me a new Webster YC hydraulic motor. My fan's hub has a lot more than just four bolts. To make sure they would play well together, I sent Multi-Wing the engineering drawings from QCC of the motor's output shaft - everything bolted together exactly as I had planned, with the new fan exactly where I want it in the fan shroud.

I'm impressed with the quality of the new fan, and it's about a third of the weight of the archaic old metal thing in there before. Not the cheapest, but it seems good to me. I'm still sorting out a new hydraulic pump to drive it, so until I buy a new gear for its shaft and put everything back in place I can't tell you now how the new fan works.

That sounds like a Borg/Warner fan blade try this number and see if it looks close

4735-41391-43

I am all most sure if you sort through the Borg Warner E catalog you fill find that fan,lol good thing about B/W fans they are not real expensive and any truck supply can order it

Thank you for the info. I found one that looks like it will work.

Generally, photos loaded to or attached need resizing to about 125kb maximum, then the site will accept them.
If you have a photo storage site like photo bucket and the likes, you can link to that particular photo. This method most all sites like best as they don't have to store all the photos as they all use to, darn it!
I believe there is a few "stickys" describing how this is done somewhere on the main part.

Sounds like your on to a fan selection now, good to hear.

good day
