filling/draining sherman trans in Ford 9N

frenchie4x4 · Oct 29, 2011

A buddy of mine has a Ford 9N with the axillary Sherman transmission. He has drained water and contaminated oil out of the main transmission while rebuilding the 3pt hydro pump. He also wanted to check the Sherman transmission but it appears to be unaccessable unless you split the trans apart from the motor. Has any one done this? and must you split the trans/engine to do this? As always any advice/answers will be appriciated Thanks Frenchie

You might go to Yesterdays Tractors website and ask this in Ford N forum. Another source might be John Smith's JusT N's

the sherman shares and oil supply with the main trans as oil is pumped thru the bearing.

if he truly wants to drain it he either has to split the tractor or pull the trans cover..

me?

I'd dump in 2.5 gallons of diesel and 3 quarts of ATF fluid, and 4 pints of 90% rubbing alcohol... run her around the yard.. till warm, then drain all 3 drains. then refill with utf or gear oil ( gl1, 3 or 4/5-MT1 ), and then add in 2 cans of seafoam transstune and call it good.

alcohol is a polar solvent.. water is polar.. it will dissolve into soloution vs emulsion and be carried out with the high detergent / solvent flush..e tc. any left over water will be sucked up by the de-watering action of the seafoam ( yep.. also has a polar solvent in it. ).
