Radiator Fan Gear Box
I do not need one of these but I am curious as to where to find a new one, or have one rebuilt: XL Radiator Fan Gear Box.

I don’t know if this applies to the gear box, but whenever I need a replacement part the first thing I do is use the part number, or manufacturer’s name to find it on line and after learning the price I call Prevost. Often they are competitive, but if not I shop using the internet.

The link/thread below may apply to you?

I am always looking for the potential trouble spot. I read the Bus Conversion article on the rebuild but honestly that is well outside of my capability.
For Jeff, can you still order?

I can and try to keep one in stock…

We just had a wonderful four days at the James Island Campground in Charleston. Met Larry and Alice Frawley while there.
Jeff. Looks to me like my fan pulley is slinging grease. Would advise replacing just the pulley or the entire fan gear box? I looked on the internet this morning for a pulley and did not find anything. What would be the cost of the replacement fan gear box? You can call me direct if you want, or I can give you a call.
By the way, I was the one that called you this past Saturday morning about the generator radiator cap pressure requirement.

Ron,
Does your fan pulley have the grease fitting, and is the gear box mounted on the support directly to the fan?
Remote pulleys, such as on early coaches required grease, but only a very small amount otherwise the excess grease was slung everywhere. If there is doubt about the pulley bearing, relax the belt and spin the pulley to listen or feel for bearing noise.

Thanks, Jon.

I will do that the next time there next weekend. I do think I put in too much grease.
As soon as I put it back into the storage bay I let her idle for a minute or two and open the engine doors just to look around a few minutes at the pulleys, belts, and listen for anything unusual. This time I noticed grease slung and got curious. After shutdown I can see the ball bearings.
