John Deere 450

Today I worked on the city's John Deere 450 dozer.  This is a great little machine that gets a lot of use around town clearing snow and doing other road maintenance jobs.  The city also has a backhoe attachment for this machine that works great for digging small holes.

The problem today was a leaking fuel line.  The supply line leading to the injection pump was dripping.  I was able to simply snug up the fitting and stop the leak.

Unfortunately I also noticed a small drip coming from the back side of the injection pump.  This will probably require pulling the pump off to check it out.  That is a more complicated job than I wanted to take on today outside in the cold and wind.
