One is off of a 216 (18" dia) and the other I got at Hershey for $4 (17" dia) and I don't know what it is off of (not sure anyways - could be a 283). What is the proper diameter of a 235 blade? Any way of positively identifying it? As always Thanks for wisdom. | | |

The 53-54 engines had the old 216-style fan blade on a 4" pulley and 7/16" belt. The blades will be "staggered" or not evenly spaced around the hub. The 55-62 engines used a fan with evenly spaced and wider blades on the 7" pulley.
They won't interchange because the fan RPM range was different, pulley sizes were different, and the fan bolt pattern (i think) was also different. Whatever blade bolts to the pump pulley and clears everything should work.

Both blades are symetrical (but not evenly spaced). In fact, the only difference between them is the tip to tip diameter. :confused: | | |

I would also be wary, these old blades can break easily, resulting in severe injury to anyone in its path. I would bead blast it clean and do a careful inspection for cracks before painting. The fans for the 235 are getting a little scarce, and no one makes them anymore. I can remember buying a 5 blade fan for a 230 when we added on a/c, the parts store had them in stock. Shows how much things change in 35 years.
