What oil should I use in a final drive?

Expert Answer

For many excavator and compact track loader final drives, the answer depends on the exact machine and whether you mean the planetary reduction housing or the travel motor section. Always check your owner’s manual first, because some models call for gear oil while others specify a hydraulic/transmission-type fluid. If you are replacing a complete final drive from VANROCK Drives, our units ship brand new, fully assembled, and filled with oil, ready to bolt on. We sell online at vanrockdrives.com with fast, free shipping, prices that include duties and shipping, and no core charges or exchanges. Every drive is covered by a Limited Lifetime Warranty.
