Replacing the starter on my Caterpillar 303 CR mini excavator

This video is the beginning of my Caterpillar 303 CR mini excavator. This machine is a 2004 model and has seen some use, it has just over 5000 hrs on it now and I purchased it used about 9 months ago. Of course I knew there would be needed repairs and this is the first major one. So my Dad and I get to work.
