I have a 1914 Roadster. A noise started Sunday and I finally figured out it was the fan blade hitting right underneath the top spout. The bushing seems ok in the fan assembly. The fan blade it about 5/8 inch back from the radiator. Only two of the four blades are hitting the top hose. Should I remount the radiator higher? If so, what is the best way. It is a brass radiator. I had new brass fittings put on it because the old cast iron fittings were rusted so badly. Should the fan blade be closer to the back of the radiator than it is. Thanks once again everyone. Marv.
How about a shorter fan belt?
I am curious; why do you say "finally figured out?" Did you not see my post in your original thread?
Marvin says the fan is hitting the upper water connection. This has nothing to do with the crank handle, ratchet, pulley, or lower water connection. The problem developed when he tightened the fan belt. The fan is too high. It needs a shorter belt.
I took a snapshot of the original page. Read my post.
The one that says "you mentioned you adjusted the fan belt..."
Correct. The adjustment did it. But it's the upper connection, not the lower one.
I guess a shorter fan belt would help then.
(but before putting the new belt on, try running without the fan, it just might work - it does for me, though I'm not doing parades.)
Tom thank you so much for your post and yes I did check that out and the fan had a lot of clearance from the crank handle. I think a shorter fan belt may work because I put a water pump on the 1914 and I think the fan is moving too far over. The clearance on the lower outlet is very good. I think the 1914's had a shorter arm. I need to see that it isn't the later longer arm too. All of these ideas help stimulate my thinking to figure it out and I do read and absorb every comment because the experience you guys have it soooo awesome and helpful! I will get it fixed thanks to your suggestions! Marv
Shorter fan belt does the trick! It is amazing how the obvious escapes me. The fan gets closer to the top of the underside of the radiator the more it is tightened. Thanks everyone! Marv .
I may not be as seasoned as the wise men here, but I had a similar issue and broke a blade off of my fan. A contributing factor was I had recently replaced my radiator and had not completely tightened the rod that connects the radiator to the cowl. Once i did that I had at least a 1/2 inch more clearance. Hope this helps.
Scott one of the things I found out by experimenting with the fan position that if the fan gets too far toward the driver side of the motor, the fan blade can hit the top of the crank just like Tom was saying. My crank bearing is worn but still OK for a while. The crank begins to sag letting the crank slope up to where the fan can hit it. It all seems to hinge on the proper fan belt length to make things work.
Here's the condition Marvin described.
A worn bushing lets the crank sag in front.
That raises the ratchet to where the fan hits it. Rather than shop for a longer belt, I installed a new bushing.
