How do I know if my final drive is going to fail?The life of your final drive depends on many factors including how often you use it and how well you maintain it. Typcially the main bearings failing or clogged drain filters are the reason a final drive stops working. If your final drive is vibrating, making alot of noise, or if the outer seals start to leak you have problems. Sharpened gear teeth in your final drive are also a problem.
Good maintenance such as checking the oil and regularly replacing the case drain filter will extend the life of your final drive. However, eventually all final drives fail. Typically if one drive fails the other drive will fail in the next six months. When deciding whether to replace or repair your broken drive think about your second drive and the materials, labour and 'time away from the job' costs of replacing one drive as opposed to two. We offer our customers a discount on any second final drive purchased. Should I buy a new final drive or recondition my existing drive?The cost of after market final drives has come down considerably over the last few years. Technological improvements have increased the quality and quantity of production giving after market suppliers greater buying power. This allows us to provide our customers with final drives at competitive rates. Get a quote to recondition your drive and give us a call to compare the price. Our customers tell us there is not much of a difference in cost between a reconditioned and one of our after market final drives. Remember, reconditioning your drive is a valid option, but typically only the excessively worn or broken parts of the drive are repaired or replaced. The risk that other parts of the final drive will fail remains.
How often should I replace my gear oil and what products should I use?We recommend you you change your gear box oil every 250 hours. Many people use SAE90 gear oil but check your owners manual, or the gear drive's name plate to identify the best product to use or the lubrication specifications relevant to your final drive. Alternatively have a chat with your local agent or mechanic.
