Replacing a Final Drive: Do You Know What to Ask?

You’re facing an already tight deadline when you machine stops dead in its tracks:  the final drive has gone out.  You need a replacement, and are fairly certain you have tracked down the exact drive motor you need.  In this Shop Talk Blog post, we are going to look at 4 important questions you need to ask when you are about to replace your final drive or hydraulic motor.

Will the final drive motor fit your machine?

Some final drives are more difficult to identify than others, such as Bobcat T140/T180/T190 final drive motors.  With these types of motors, first you need to identify whether or not it is a four port motor, then determine if it is a 12 bolt or 6 bolt model. If it is a five port drive, then you need to determine if it is a short-nose or regular-nose model.

Is it a new, rebuilt, or reman final drive?

We’ve talked about new, rebuilt, and reman final drives several times on the Shop Talk Blog. Here we just want to emphasize the importance of being sure what kind of drive you are getting. Also, keep in mind that new final drives could include new aftermarket final drives that are a match for your equipment but may not be from the OEM.  Some aftermarket manufacturers manufacture higher quality drives than others, so be sure that you know the manufacturer of your replacement drive.

 

What kind of warranty is offered on the final drive motor?

There are two things that come into play for warranties:  the condition of the drive (new, reman, rebuild) and who you will be purchasing it from. Take the time to read the warranty information before your purchase a final drive and be aware of what limitations apply. These warranties have very definite warranties and conditions, and what may sound like an awesome warranty may not be so really be beneficial to you when you read the details.

If you have any questions about it, the sales team should not be reluctant to discuss it with you.  Note that, as of right now, with new final drives you can expect to see a one or two-year warranty, and a one-year warranty for reman or rebuilt final drives (if one is offered).

 

What is the turn around time for receiving the drive motor?

If you order a replacement drive, verify how soon it will be shipped to you and when it should arrive. Make sure they have your drive in stock before you place the order, or you may be in for an unexpected wait period.  Some companies wills ship an in stock final drive or hydraulic motor on the same day long as the order is placed before 3 p.m. their time.  If you are sending in a drive for reman or repair, however, there will be a wait time.  You will definitely need an estimate of how soon they can get to work on it and approximately how long it will take to get it back to you.  The drawback is that the better the shop, the busier they may be.  Experienced shops can usually provide very accurate turnaround time estimates.

 

 

Ready to Replace

When you have found the drive motor you need, make sure that it will fit your machine; double-check whether its rebuild, reman, or new; find out about the warranty (if one is available), and verify the turn around time for receiving it.  This will save you time, frustration, and maybe even some money.
