    I just drained the fluid in in my 203 with a part time kit and i looked in the chiltons manual and it says to put in 10w30 motor oil. but the fluid that i drained out looked and smelled like gear oil. am i supposed to put gear oil in because of the conversion or did the previous owner put in the wrong stuff??????

    Zakks right...

    I've seen it all run in 203's.... I spoze anything thicker and slippery-er than Mountain Dew will work.

    I run ATF in my 203 range box. /forums/images/graemlins/deal.gif

    the reason your not supposed to run gear oil in them is that it is too thick to properly get thru the system to one of the bearings...I think the rear.
    I run motor oil in mine w/ a touch of Power Punch or Lucas

    Do you just fill it up until it starts to over flow?

    Yup.
    If it's part time converted put the back wheels on ramps and over fill it. The chain was an intergral part of the lubrication process. Part time means the chain is not slinging oil up into the reservior in the tail shaft housing that feeds the pump that gets oil to the tail shaft bearing.

    thanks guys, i think im gonna try 20/50 and see how it works out, it seems like a heavy motor oil would be the happy medium between the two

    Then fill it till it runs out of the hole on level ground. New Process felt that was enough.
