Excellent work!

I know this is an old thread, but I have the same situation. I am only able to find the splined coupler with 1 1/2 inch OD. Any thoughts on where I can find the 7/8 13 spline with a lesser OD, or did you buy a larger one and turn it down?

Did you try our Sponsors Patton or Houtz ???

I believe you will need to use the 1.5” OD coupler. This will need to be done by a machine shop. You have to bore the old splines out of the fan and turn the OD of the coupler down to press into the fan ID.

I have take the gear in the chaincase of snowmobile artic cat, same spline
but need grinding outside and the thikness it's smal, may be 3/4 , 7/8 but
it's one possibility , i have repair my 451 with that .
I speak in french apologize for my english !

Looks good. All the more reason I need a mill/lathe :D

I repaired my splined shaft and it just broke again .It lasted maybe 2 winters. Is the splined shaft you used hardened and where did you get from .. Mine came from surplus center in Lincoln NE ..It surely should last longer ..what did do wrong
