Fan Belt Length

Post by ModelTWoods » Fri Oct 11, 2024 1:50 pm

Anyone running a low head on a 26-27 engine with large 26-27 crank pulley and water outlet mounted fan? What length fan belt do you use? No water pump involved.

Take a cloth tape or a heavy string and make two measurements around the pulley’s like the fan belt would run. One measurement with the fan adjuster at low point and another measurement with fan adjuster at high point. You will a fan belt that is between those two lengths.

Kevin, I knew I could do that. I was just wondering if anyone had or is doing this and what they found would work.
