9N hydrolic fluid amount

[milkmanNC]

I have read on this forum somewhere (can"t find the post in search) that when changing the hydrolic fluid, to pull the rear plug first and work your way up to the front plug. Also seem to remember that it should hold 4 and 3/4 gallon (might be wrong).

Well with tractor running and the three point lifted no hydrolic fluid was touching the dip-stick and with the three point in the down position it would barely touch.... so I added more.
Now when tractor is running the hydro fluid level shows full on the dip-stick.
After cutting tractor off and it sitting for several hours, without the 9N running the dip-stick is showing over full.

Any advice would be appreciated.

No, I do not have a F04 shop manual, just an original shop manual that tells the fluid amount to add if the tractor is totally dry.

With totally clean sumps like in the picture & no water in it, and the correct dipstick, it will hold 5 gallons & register as such on the dipstick......an hour or so after you pour it all in the filler plug on the tranny cover & it sloooooowly levels out in all 3 sumps.

That's one reason why many folks just remove the bottom bolt on the inspection plate.

So, I need to pull the bottom bolt on my inspection cover and let it sort itself out.

Thanks for the reply!!

That"s what they say but sure seems like the man who designed the whole thing included a dipstick with markings. Pulling the bottom bolt and lowering it to that level is O.K. but is not how it was designed to be. More is better.

Tom.......you'd prefer OVERFILLED hydraulic oil sloppin' out the rear axle trumpets to grease yer brakes??? ...or... pumpin' out the tranny front main bearing to grease yer clutch???

And what is the difficulty of reconciling 5-gals vs 4-3/4-gals??? yer tractor hydraulic pump will NEVER know the difference.

The bottom 6-o'clock bolt hole is more than correct to set the hydraulic oil level to PREVENT overfill leaks. The flat hydraulic dipstick is NOT a "calibrated" dipper. Its accuracy is suspect. ......respectfully, Dell, the dipstick

When I changed the hyd fluid on mine,I put 4-1/2 gals.,ran itwith arms up&down a few times.I then shut it off,waited about 1hr doing something else,then went back and remembered the bottom hole,took it out,held about 1qt more actually read about right on the stick[a little low].---lha

Designed for 5 gallons-ought to have 5 gals.

The problem is that the sumps get sludge & water in them. At 5 full gallons, and old seals, the fluid can get into the brakes because 5 gallons gets the level well above the "full" mark thanks to the crud in the sumps.

The way to do it right is drop the pump & clean it all out.

didja notice that on later models they went to a level check plug on the tranny and diffy.. IE.. places where too much oil can hit the clutch or brakes??
