Your excavator’s final drive works hard every day. It powers the tracks, transfers torque, and keeps your machine moving. But none of that works for long if your final drive seals fail. Oil leaks, dirt ingress, and premature wear can all lead to costly downtime. That’s why high-quality seal kits like SA8230-32400 and SA8230-32620 are essential.
At Pro Construction Parts, we supply premium OEM-spec seal kits designed to keep your final drive sealed, lubricated, and protected.
What Do Final Drive Seals Do?
Final drive seals prevent oil leaks and block dirt, grit, and water from entering your travel motor. They protect gears and bearings inside the drive, keeping them lubricated and extending service life.
Without a reliable seal, oil can escape and contaminants can get in — causing overheating, gear wear, and total drive failure. Replacing seals before they fail is one of the simplest and most cost-effective ways to protect your machine.
SA8230-32400 Seal Kit
The SA8230-32400 final drive seal kit is commonly used on Volvo and other excavators with similar travel motor designs. It includes all the necessary components:
-
Floating face seals
-
O-rings
-
Backup rings
-
Dust seals
-
Support rings
Each component is made from high-grade materials designed to handle pressure, heat, and vibration. This kit is built to OEM specifications and tested for reliability.
SA8230-32620 Seal Kit
The SA8230-32620 kit is a related variant, sized for specific travel motor models. It provides the same level of protection and performance, but is dimensionally tailored to certain final drive assemblies.
If you’re unsure which kit your machine needs, our team can help confirm compatibility. Just provide your machine model or serial number.
