Expert Answer
For a Cat 259D3 compact track loader, VANROCK Drives recommends checking the machine service specs before changing any final drive oil. If you are replacing a complete final drive assembly, our units ship brand new, fully assembled, and filled with oil so they are ready to bolt on. We sell online at vanrockdrives.com with fast, free shipping, prices that include duties and shipping, no core charges, and a Limited Lifetime Warranty. If you are looking for a replacement drive for a Cat machine, note that VANROCK Drives is an independent supplier and is not affiliated with Caterpillar.
