Re: How to take off flywheel
Once you remove the nut you can take that "ring" off. Under that ring you will find 3 threaded holes that you can use to thread the bolts of your flywheel puller into. I use a cheap harmonic balance puller with GRADE 8 bolts, getting the correct bolts will keep them from breaking off.
I don't know what year that motor is, post that info and someone can tell you what size bolts you will need. All 4 of mine use 1/4-20 but different HP can use bigger bolts.
