Yeah. Remove the whole rear fender assembly. Remove middle platform. Your gonna have to remove the two hydro pedals and deck adjust knob. After that remove fuel tank. Took me about 45 to put new belt on my 325 a year ago. Pretty straight forward
shortthow50 is almost right, the only difference is that you do not need to remove the middle platform for this model, just slide the rear fender assembly rearward and lift. I'm actually replacing the pulley on my own gx345 right now.
- The process I've found that works is remove the (6) fasteners that hold the rear fender on with a 1/2" socket (2 bolts on each side by the seat and 4 bolt and nuts conecting the fender to the middle platform). you'll need a open end box wrench to hold the bolt end.
- Next disconnect the seat sensor from the bottom of the seat if not already done - perminently.
- Carefully lift the fender/seat assembly off of the tractor being careful not to damage the seat sensor cord, and place in a safe location.
- Next remove the (1) hex nut that holds the fuel line onto the frame using a 10mm socket (this should be located by the middle platform on the "driver side".
- Caefully lift the tank off of the tractor, leaving the fuel line connected and place on the ground.
- Since the pully is stripped there isn't much to hold the shaft and turn the fan nut off, so I found that if you use an impact wrench with a 3/4" socket and give it a quick hit the nut should come right off.
- Remove the fan, work the belt off of the pulley (I just ran a screw driver in and turned the pulley to work the belt off) and remove the pulley.
(About 15-20 minutes tops to take apart)
- just do the reverse to put it back together.
The pulley should cost around $40 at your local JD supply shop.
Good luck and hope this helps everyone.
