Hello guys,been a while since I posted here, due to moving to another house. I want to change the oil in the gearbox and rear axle from my dexta. I've searched the archive and found out that I should use SAE 30 oil. Before i put the new oil in, I also should drain the oil and flush out the rear axle with a mixture of diesel and 30W oil, because there's cream coloured oil in the rear transmission. I should put in 2 gallons of this mixture and run the tractor around for a short distance/ 15 minutes. Then drain and refil system with SAE 30 engine oil or any good quality engine oil. Now I have a few questions. I probably could find some answers in the manual, but I can't find the paper version right now, and due to my slow internet, searching the online version would take quite some time, so please help me. 1. Are the gearbox and rear axle one compartment or are they seperated?
2. If they are seperated, where do I drown and fill the fluids?
3. How much oil goes in the gearbox and the axle? in liters please 
4. How many liters is a gallon? Thanks, Dieter IP: Logged |

They are different compartments
According to my Dexta Instruction book
23 pints / 13.07 litres in the Gearbox
34 pints / 18.82 litres in the Rear Transmissionlitres in a gallon is 4.546 It also says above 32C SAE 140
-12C to 32C SAE 90
-12Cto -23C SAE 80
below -23C 80 Mild EP *10% Kerosene
for both gearbox and Rear Transmission Good Luck Ps look for the rear transmission oil filler under the right of the seat. Have not found the drainers yet! PPs please let me know where they are! IP: Logged |

@ nmgm2the drainers are, as usual, at the underside of the castings. When you lay down under the tractor, you'll see them immediately. Thanks for your help. Dieter IP: Logged |

Ok now I'm getting kinda confused here. According to the information I have, the proper oil for the Gearbox, Rear End and Motor are all the same. SAE 30 HD Anyone care to clear this up? Randall IP: Logged |

It all depends on the ambient temperature of the area your working the machine in.IP: Logged |

Chaps,As far as Ford is concerned, the oils in the transmission and hydraulics is 30W or Multiuse. I can find no record of 140W oil in either at whatever temperature in any of my Dexta specifications which were suppled by FoMoCo when I was servicing the tractors. Certainly the Major did have the heavy oil in both but (as I laid out in the oil specs on this site) the specification was changed at the time of the Dexta introduction. I believe that it is possible that the early tractors may have the heavy oil in them but the hydraulics would not function correctly in all but the highest temperatures. If someone has got a FORD published instruction manual for the Dexta or a FORD workshop manual with the heavy oil specified, please post details to correct my information. It is possible that some were published prior to the oil specification change or that the British manuals and information had these specs ommited because they did not apply here. All the information regarding oils that I have published comes from Fordson Workshop Manuals and Service Letters that were issued to me at the Ford dealerships or at Boreham House. These are not my opinions. In todays society I would be foolish not to go by Fords recommendations as it could drop Oscar and I in deep trouble. regards Brian IP: Logged |

I am not going to start an oil argument like I did on the Fergy board at YT , but make sure before the plugs go back in that you jack up the tractor from the front, then from the back. You won't beleive how much more comes out. And don't put kerosene in it. You are way better off to change it twice than put that crap in. IP: Logged |

My gearbox is currently full of an oil / water emulsion any ideas as to how to flush it out fully and do you think it will have done much damage if so what is the most likely kind?Thanks Michael Ps The preivous owner used to take the gear stick cover off to change gear sometimes if he lost the gear linkage. But he never tightened the cover so it filled with water. Luckily he never lost any fingers! IP: Logged |

The oil/water mix you describe is common to tractors that live outside. It gets in thru the shifters and the breathers. On mine, I removed the pto shaft and lift cover to get the gunk out. The transmission is a little harder to clean out. If you do use kerosene, change the oil twice to make sure that it is cleaned out good.IP: Logged |

Just a note of warning If the gearstick cover was removed you will probably find it is because it jumps out of gear or gets stuck in gear sometimes. It is a common problem have a look at previous topics on the BB. I was given a good piece of advice complete with pictures when I had the same trouble. Even as a non mechanic I managed to weld a lump on and file it down to solve the problemIP: Logged |

Kevin,The kerosene/oil mixture for flushing the housings was a Ford recommendation here in England. Kerosene does no harm and was also used to thin the rear axle oil down to run in cold weather. In the 6X and 6Y series 2000 and 3000 with the engine mounted pump, Ford sold kerosene in gallon cans as an additive for the 30w oil when using the tractors in the English winter. regards Brian IP: Logged |

If memory serves me correctly, there is an oil check plug on the front right side of the rear axle and one on the left back side of the transmission. They are the standard square nut type. These will be helpful if you loose track of the amount of oil you've put in or wish to top of it off. I changed the rear axle oil on my family's '58 Dexta recently and found that 34 pints (4.25 gallons, US) hit right at the check plug.------------------

So much for my memory. The transmission check plug is on the right side of the transmission below the fill plug. The rear axle check plug is on the left side of the rear axle near the clutch pedal pivot point.IP: Logged |

-Well...
The drainer for the rear axle are not easy to find, if the Dexta is equipped with handbrake.
The plate (E314-FD-9) makes it quite difficult (but not impossible) to use. quote:

Hello,
Found this old message (quoted above). ---------- I have an owners Manual for Fordson Dexta (named: "Form.S-464.4000.5.58" at the backside of the manual). This manual tells us the following:
below -10°C = SAE 80
-10°C up to +30°C = SAE 90
over +30°C = SAE 140 ---------- I have annother owners Manual for Fordson New Dexta (named: "Form.S-464.2000.7.63" at the backside of the manual). This manual tells us the following:
below -10°C = SAE 20
-10°C up to +30°C = SAE 30
Alternative SAE 20W30 all weather ---------- -Maybe different owner manuals printed different years tells us different recommendations.

Think we are all trying to forget the 80/90/140W recommendations . That book was very early and when the nydraulics gave problems due to the heavy oil not moving through the small ports, Fords quickly revised the oil specifications. At the same time they changed the oil specs for all tractors to the 20/30W ones. Ford chaps made errors at times that seem inexplicable. The decission to make a tractor with an 8 speed gearbox with two gears giving the same speeds at the same revs was another one. IP: Logged |
