I'm New Here
It's rediculous how difficult it is to find a part number for a simple seal. I have a O-360-A1A with a Hartzell HC-C2YK-1BF prop. I need to change my alternator belt and need a new seal.
See https://hartzellprop.com/MANUALS/115N-0000-A.pdf
Figure out the type of Hub/Flange you have -- Table 2-1
Then reference Table 3-1 for the O-Ring required.
-228 , unless you have an N flange hub.
See McMaster-Carr, Part number 1288N188 for the Viton -228 O-Ring. (https://www.mcmaster.com/products/o...uper-resilient-viton-fluoroelastomer-o-rings/)
Cheers,
