Hydro-Gear ZT-2200 - repair - remove pulley and fan

[yyc2yeg]

Folks, I am new here, and have a Cub Cadet RZT50 with a right hydro-gear that is shot. I have started to take it apart but I am stuck mid way through because I cannot seem to figure out how to disassemble the pulley and fan assembly that drives the pump. The fan and pulley do not match any of the assembly diagrams that I am able to find, and I have tried removing the main nut to the pulley unit and then banging on the pulley wheel with a hammer but it hasn't budged at all. I have some pictures:

If I thinking right tap the three holes closest the center and use a point puller such as a harmonic balancer puller.


I also thinking that pulley is the 4.5 inch one; although, there is a 4 inch one too.


It might have a different PN since this a ZA series and I don't have the IPL at hand. Requesting one From Hydro Gear.
