multifuel engine fan measurements

[JasonS]

I am looking for a fan to fit a deuce gas engine with four bolt holes. The multifuel fan looks like it might work. Can someone measure the hub pilot diameter, bolt circle diameter, and overall fan diameter? Thanks.

A LDS fan MAY work but a LD/LDT will not, diffrent bolt holes, diffrent spacing, diffrent count.

Which gas engine, GMC or Reo/Studebaker?

I am replacing the original REO OA331 engine with a later model REO OH200 engine. The later model engine has a larger water pump and a 4-bolt pattern for the fan. The original OA331 fan fits on to the hub but requires six bolts.

Multifuel fan is also 20"diam. but heavier, with 6 blades equally spaced, 4 bolts 5/16”, on 2 3/16" bolt circle. Center hole (pump shaft diam.) is 1 ½”.

Gerhard, thanks for taking measurements. I need a fan with 1.75" pilot and 2.5" bolt circle.
