818 Road tractor

This is one big bad truck. 

The 818 is big.  How big you ask?  Note the ladder on the front of the truck to access the engine!

The fuel pump on the 818 wasn't working properly...  Nothing to do but pull it off and service it.

Here is a hot upgrade!  The 818 did not have a heater in it.  While a tougher guy would take the cold, the owner of this machine requires some comfort.  Or perhaps his girlfriend demanded it.
