Warp Feed wear/replacement parts question

[FaSSt]

I am getting a used Warp Feed along with a Warp body in exchange for my vertical Emag body.

I need to know what components of the Warp typically fail when a problem occcurs. Since I only have a Warp body, I will not be playing without an operational Warp, so this is kind of important to me.

I know I should probably get the little o-ring that acts as a drive belt, but what else?

About the only thing you should replace is the drive belt o-ring. Other than that, take off the front half and put some lightweight grease on the white gear on the warp wheel. Make sure the housing is cleaned out from any oil residue left behind by paint.

The only other thing is to check and make sure it has the brass motor pulley. If it's the black delrin one, get the brass pulley.
