I think that there are two flywheel pulley diameters for the 4 cyl Lyc, does anyone know what they are?

TIA,

Red Hamilton

Hi Red,

 

I have two "ring gear supports".  The one I would consider standard  measures 

9 3/4 inches on the outside with a 3/8 inch wide belt groove.   This one is 

marked 75030 ASSY.

 

I also have one with 2 pulleys.  At the rear is one 8 3/8 inch on the  

outside with a 1/2 inch wide groove.  Just ahead of this groove is one that  is 8 

5/8 on the outside with a 3/8 inch wide groove.  This one is  marked LW15602 

ASSY.  This flywheel would not work on my IO-360-C1E6 with  the front mounted 

prop governor because the ID of the pulley interfered with the  case.

 

These both are for an IO-360 with prop bolt/bushing holes about 3/4 inch  

diameter.

 

Hope this helps.  There are surely more flywheels than this out  there.
