Model T Ford Forum: Forum 2015: Fan Hits Lower Hose

I installed my new fan using a 27" endless belt (the polyester type), and the fan is just hitting the lower radiator hose. The belt seems tight, so I don't think I can stretch it much more. I have a new split aluminum crankshaft pulley plus I built up the worn top pulley a bit with epoxy. The next larger size belt is 28-3/4". Should I try that?

Is it hitting the hose itself or one of the clamps? The larger belt would allow you enough slack to adjust the fan away from the hose, but if it's hitting the adjusting screw on the clamp, it would be easier (and cheaper) to just loosen the clamp and move it until the fan clears.

The fan is hitting the hose itself.

The extra 1 3/4" in belt length will only raise the fan about 1/2". Probably more than enough to clear the hose. I would check and see if you have an additional 1/2" adjustment ... if so, no harm in trying the longer belt.

It may be that the combination of the new crankshaft pulley and your modification to the fan pulley has altered things enough that the stock belt won't work.

Good luck.

The larger size belt will raise the fan 7/8", if you're not running a water pump. Will that work without causing other interference problems?

I think I'll try the longer belt.

Hope that works. Dave

Are you rotating the eccentric in the right direction? One direction moves it to the right as it raises the fan and the other direction moves the fan to the left as it raises. However, if you move it the opposite way, you might have interference with the timer. I suspect one of three things. 1: the belt is too short, 2: that you need a new upper pulley. 3, You have an incorrect lower hose. The lower hose should consist of two short hoses with a pipe between them.

Can you send us some pictures of the area?

Norm.., I have a '23 model, which I don't think has the fan. The hose is correct. I ordered a longer fan belt, so I'll post the results.

Oops... I meant to say the fan has no eccentric.

You're right. I misread the 27" belt as 27 year model. Yes you need a longer belt.

Well, I fit the 28-3/4" belt, and it seemed to work, even though I had to adjust the fan fully "upward". I discovered, however, that the longer belt now rubs the timer control. My next step, i guess, is to get a 28" belt made up.
