I inherited a 1961 Fordson Dexta. It is used for light duty, pulling a 4 ft brush hog, springtooth, etc. I was told to use 30w motor oil in the differential from the original owner. The hydraulics hesitate sometimes especially in hot weather. Could the wrong oil be my problem?
Thanks Frank

My understanding is that engine oil & gear oil viscosities (sic) are measured differently hence the different figures for each. However I'm told that in actual fact, 30W engine oil has the same viscosity as 85-90W gear oil. I would have thought 90-140W gear oil would be way too thick unless used in high ambient temp conditions. What says you to that Burrhead?

I say amen to that Bro.

I'm in SE Texas where it was 103 in the shade yesterday. If we go below 50W even in our cold months the lifts won't lift your hat.

I was taught the same thing as far as viscosity goes but after watching our county barn ruin some engines and then Ford did'nt stand the repair warranty because Ford claimed there is a difference I figger to play it safe and go with what works.

it usually starts a family feud when your question comes up, but the original Fordson manuals call for 80W gear oil in the diff and trans both for summer running.

The 30W was recommended for cold weather. Most times when a Dexta lift hesitates it is from water in the oil or one of the relief valves has trash in it.

To clean the case and lift system I just dump the gear oil out and put 5 gals of fuel in the diff and run it thru the motions til the fuel gets hot and washes the system out.

Then after I get all the fuel drained I refill the box with 90W-140W. The system holds 5 gals and 1 pint.
