This is my inspection sheet.
For the axles you use SAE 75W-90 or 75W-140 oil. You change it every three years or 250,000 miles if the vehicle is used for line haul and 60,000 miles or 1 year for vocational use.
For the transmition you use either 30 or 50 weight synthetic oil and you change it every 250,000 or 500,000 miles respectivly.
For the motor oil you use 15W-40 Delo 400LE motor oil. You do an oil change every 25,000 miles, 800 hours or six months.
There are 51 grease points on this particular truck and you use a lithium based grease. The service interval for the grease points are every 50 hours.
I will post my pictures of me doing the inspection of the truck later tonight when I am at home in another blog post.

Again sorry this is just not working right for some reason. This week I learned not only the location of these things I have taken pictures of but of many things else too including the 51 grease fittings that are on this particular truck. I also learned why preventative maintenance is so important. Its much better to do the little relatively quick and inexpensive things to keep the unit running good than to ignore them and put it off till something major goes. Don's example of Lynden Ice was perfect of why you should do preventative maintenance.
