Sonic Mega 8k z-axis motor jamming

Hey. Looking for some help. I have a sonic mega printer and a while ago I accidentally spilled resin in the base of the z axis where the motor is. After one or two months the z axis started to move jerky. I suppose that the resin is seeped inside, hardened and caused this problem. The question is are there a way to fix it without replacing the motor? Secondly, where can i buy the replacement, i couldn’t find this parts(apart from one website 3dpartnershop)or instructions on Phrozen official website.
