I am changing the oil on my John Deere 450 C Bulldozer. This process will be the same for any of the 450-C family of crawlers. We also have a JD 450c Track Loader and the process is the same.

These JD 450s are great older crawler/loader/dozers and are pretty easy to work on. Parts are still available and parts tractors are rather cheap to find.
I have the service manual for this dozer and will be doing all the work on it myself. I will try to get videos of everything I do on it so check back for more.
