Transmisson Dipstick Location and recommended Oil for QLD

I was told to put this post here!

Hi All! I have a 1955 TEA 20 that I know little about. I have to shift it from a flood prone area relatively promptly and it was driving etc about 6 months ago. My concern is that it has stopped leaking transmission oil and I would like to know how to check the level or what sort of oil should go in there. Any help would be much appreciated. Bill

Hello Bill , an old saying '' If there is no oil under it then there is no oil in it !''
Dip stick on the right hand side rear will show the correct level [ sit on tractor look down and towards the rear on the right , there is a side plate with a dip stick there ] Seeing that it is from a flood prone area draining the oil from the three bungs under the back end would be a good start , it may have had water contamination in the past .
The gear box and rear transmission are all inter connected , they take 25 litres odd of the same oil . Universal tractor oil 15w40 is fine , probably the cheapest available as well . The engine can take the same or if it is a little worn try 20W50 seeing that you are in a hot climate . Once filled the gear box only shows up as half full so don't be concerned . Fill it all slowly through the gear box top bung in about 5 litre lots , leave for some time before filling the last five litres as it takes a long time for the oil to pass through holes in the casing to reach the rear. .

Charles,

I filled the sump in my old to35 with gl-1 90 weight
mineral oil per the booklet.

During the winter months the pump is slow to lift
the arms. Is there anything I could add to the sump
oil that might thin the oil some, but not hurt my
hydraulic system.
Thanks Fred

Quite simply switch to motor oil like a bunch of us have. GL1 is a mineral oil and pulls moisture into it thus leaving ice in the winter months and a very slow working three point hitch. I switched to 10w30 about 5 years ago. It works great and is cheaper than GL1.

how often do you use the tractor in the winter? unless you live in a snow region I am guessing not much. let it warm up for 15 min before you get busy, but I think you already know that.

Away at the farm for a few days and missed these posts .
Oil designations in Australia seem to differ a lot from the US . 15W40 is just plain old engine oil , 90W oil is something we put into differentials and slasher gearboxes , much heavier than anything used in a backend or engine . Got told off [ very nicely ] here when I questioned the use of 90w oil in an engine as it seemed too heavy by our standards , turns out it is completely different oil .
Queensland is hot ! at least most of it , so a heavier oil might be justified .
I am sorry Maxwell , I don't know of an additive to thin the oil safely , I would do as suggested and use motor oil , it is far better than anything produced in the 50's and will offer much more protection than single weight oils . Cold is not something we are used to here , the only ice I see comes from the fridge
