    D6C engine side covers

    I made side panels for D8's out of 1/2 inch plywood. they held up quite well. I made them for working in winter weather. They can be miserable in sandy or very dry soil tho. I could remove them in 10 minutes in those conditions. If I owned the dozers I would have made them out of 11 gauge steel.

    Tach and hr meter not working

    Although you found one section of the Y/R wire damaged it could quite possibly be damaged somewhere else in the harness. Eliminating it by running a jumper around it may be another thing you could try if the problem persists.

    Can not get this fitting to take grease.

    If all else fails --- measure the distance from the top of the pin to just a little below the grease zerk. Lower the pin and remove the zerk and see if the bushing turned.
