If you don.t have the proper 1 piece puller that threads on the shaft end, just go and buy the 3point puller..,if you use the 3 point puller,,,remove the ring first,,be careful to not strip the head of the ring retaining bolts,,,you will need lots of heat,,,according to Loctite factory specs,,,you need enough heat to melt the red Loctite…I like to put “stress” on the large bolt,,,using a power bar,,,unless you have an air gun..then heat it,,,and wait for it to pop off…so be able to catch it,,heat is your friend..as it is for removing the pto
