Single Roller

Pop loose the plastic grate at the bottom.

Locate and remove the wheel leveling screw from the front bottom corner.

Remove cotter pin from the pin that mounts the wheel assembly to the refrigerator. Tap out the mounting pin.

Lift out the wheel assembly.

Remove the Roller pin from the wheel assembly. I used a Dremel tool with a cutting disk. A hack saw will also probably work.

Install the new roller pin and wheel into the wheel assembly. Use a hammer or vice to peen over the end of the roller pin.

Reinstall and adjust wheel assembly.

With roller wheel assemble lose from the wooden block remove front elevator screw from the front frame. next remove cotter pin with the pliers and pull assemble pin. next elevate assemble out. drill out axle on the crimp side insert from the hardware store one 5/16 x 21/2 bolt with nut and new wheel. reinsert assemble in the reverse order. Remove wooden block and adjust height of wheel. replace grill. job complete. good job

The good news is that the part (the wheel was available.) I bought two in the event that the other wheel may break in the future. The bad news is that the housing that holds the wheel was riveted together by the wheel axle. It would have been nice to know that before I bought the part and if the housing with the wheel installed was available. The refrigerator was at my summer house a hundred miles away. Anyway, we had to grind the end of the riveted axle to dislodge it from the wheel housing. With the axle dislodged from the housing we were able to install the wheel and then hammer the end of the axle flat to keep in place, like the original rivet installation. It is not perfect but it held and should be fine. I am glad I was able to get the part and will be back in the future, if in need of other parts.

proped up frig, loosened screws, cut pin, installed rooler w/ new pin, rounded pin end, reistalled, lowered frig...everyone happy, thanks again partselect.

As per suggestion I replaced the water inlet valve.
I pulled out the refrigerator and removed the cardboard panel. I removed the water inlet unit by removing two screws. I used pliers to take off the the tubes to the ice maker and the water. Then removed the inlet supply tube. Installation was the reverse process.

However this did not fix the problem. After further research on another web site, I realized that the diagram that was furnished by PartSelect did not fit my refrigerator. What I really needed was the ice maker module. So I need to order the right one and I can't return the wrong part because I installed it. So I just left the lever in the ice maker in the up postion. the ice maker is still not working.
