Today’s project…. I found out that I have a newer fan pulley adjustment on the 27…. Let’s just say that the eccentric center has not moved in a long long time…. It was rusted fast and there wasn’t a good way to use a press to remove it so I ended up taking it to the vice after soaking it…. And carefully tapping it out with one of my three-quarter inch sockets that fit the housing perfectly…. I was sweating a little bit because of it being cast but as the picture show she’s moving well now….. There’s a little bit of side play so I ordered a set of new bushings for the shaft….. Darn this stuff is fun!

Those fans were on the ‘26 and 27 T’s. It has a reservoir just behind the fan that should be filled with engine oil (thick enough to flow. Not grease) which travels through the hollow center of the shaft and exits into a void between the front and rear bushings to oil the shaft from the inside. The belt is tightened by twisting the eccentric fitting. Jim Patrick

Awesome drawing my friend thank you…. I imagine there is some seepage by the shaft head…yes?

Minimal - there's a paper/cork gasket between the fan & the pulley & a felt at the rear.

Here are four photos of just a few of the new parts that are available for the rebuild of your fan that will stop any leaks your fan might currently exhibit: 1. reservoir gasket, 2. the rear felt gasket, 3. the fan shaft and 4. replacement bushings. All available from the antique auto parts vendors. Pictures are from the “Lang’s Old Car Parts” site. If you don’t have it yet, you will want to purchase the “T-1, Model T Ford Service Manual” (last photo). Jim Patrick
