thirty fan

On the drive to my thirty’s fan the bearing sounds noisy and there is play if you hold the fan you can wobble it not much but there is play how easy is it to replace the bearing? If it’s not leaking through the bearing would you just leave it alone?

Very easy to replace once you get the radiator off. Be prepared to find that the shaft needs to be repaired or replaced due to shaft wear in the spring pressure fan drive area. I turned a new shaft and repaired the floating part that rubs on the friction .

I agree, when I had mine out both bearings were rough and the shaft was worn, I replaced the bearings with sealed bearings and had the shaft spray welded and turned true.

Or with Stephens skills with a lathe you would just make a new shaft.

you can see from the margins of the bronze how worn the bore and keyway was on my collar. Also the keyway was worn sideways 1/4" at least (well anyway, I did bore oversize before brazing to keep a uniform layer of bronze). If the spring loaded collar has a lot of wear, then the positioning of the fan is mushier. It also need to be able to float on the shaft & keyway to take up and prevent undue wear on the drive frictions. I found a lot of wear overall on my shaft so I just made a new one. I also used sealed bearings hoping to keep any crankcase oil from leaking down the front of the engine-it is working well so far & made many laps around at Carthage.
