I believe you can use your axle from the rear wheel. After you've remove the bolt from the fan, you should be able to screw in the rear axle into the now exposed hole. Just keep turning it until the fan pops off.

Bears,

we are trying to avoid people using that route as it isn't the best way. Yeah it will work but it could screw up the threads on the fan if the fan is meant to be reused. Probably not in this case. There is no reason a M14 x 1.5 bolt cant be picked up at a hardware store.



Just like we don't want to tell people to use an oil filter bolt to pull the rotor.

Good to know! And here I was keeping a spare rear axle on hand just for that purpose. I'm gonna go with the sound advice and pick up an M14 / 1.5 bolt myself (ehh...actually I never even thought to just look in my bucket of bolts...I prolly already have one)

Nice fan. I have seen them like that. Get the right bolt and hold onto the fan fins as you screw it in. At a point it should bind and then it's a hair more of a turn and it will fall off in your hands. Might be a good candidate for an electric fan.

If memory serves me, you use the front axle. Do it up firm, then tap the end with a hammer.

DO NOT keep winding on the axle !!!This will surely damage the thread.



I have done this many times, always successfully.



Or spend money on a bolt.

You won't damage the axle, the fan hub is soft aluminum. Your fan is toast so don't worry about it. Just thread the axle in firmly and hit the end of it with a hammer using a block of wood as a buffer or use a plastic hammer. Tighten again and repeat.

While I agree that the fan is already toast stripping the threads in the fan hub before the fan comes off if it is stubborn will lead to all sorts of greif with fan removal.

The fan hub appears to be some sort of alloy so you need as many threads engaged as possible to prevent stripping. The taper on the end of the axle won't let many threads engage.

Not all front axles are created equal. All of them should share an axle with a 14mm thread on the rear. And example of the front would be a 78-80 front axles is 14mm and the front axle of an 82 is 12mm.

Although they may in fact have the fans in stock, often parts are listed that are in fact NLA.



If you try to buy one of these I hope they ARE in stock.



Also, NOS plastic parts sometimes already have some age deterioration even though they have never been fitted. That said, it's bound to be better than yours.

This is one of many reasons why I encourage people to convert to an Electric fan.As the bikes get older we may well see more Mechanical fans grenading and taking the Rads out.Much better to convert than get another Radiator IMHO.



My 2 cents.
