I have a 323e and would like to replace the rubber grips on the joysticks as they are tacky and peeling. Is this possible to do? looks like they are just bolted on.
Welcome to HEF mdemott ! EH machine? Yep, for a whopping $685 + each. Below is a picture from the parts page, but may not be the ones on your machine because you did not supply a serial number.
If it's just sticky plastic, you could try cleaning them with alcohol. I use denatured alcohol to clean sticky buttons and plastic in older car trims.
