Swing Motor Seal Kit is the set of rubber rings and seals we use when our swing motor starts leaking. It includes shaft seals, end caps and O-rings that fit into the motor housing. We take the motor apart, remove old seals, and press in new ones from the kit. That stops oil spills and keeps swing motion smooth. Seals wear out with dirt and pressure, so swapping them is a must. Fresh seals, happy spin, no messy oil on your job site.
