Transmission/ hydraulic dip stick

Hi,
I just purchased a 1958 t035 gasser from my wife's grandfather.

The hydraulic arms seem jumpy? I know it has a pto seal leak, so I figured I'd check the dip stick. The problem is I can't find one. The only one I see us for the motor?

I even had my father look... Still nothing

Is it possible that it might not have one? If so what level should the oil be?

Maybe I'm the dip stick lol
 
I have a 1957 TO35 gas
The transmission hyd oil dipstick on my tractor is on the right side of the tractor under the lift lever,

I have caught my foot on it getting off the tractor a number of times over the years, you can pull it out losing it, and never know it,

I finally just chained it to the body of the tractor, no more lost dipstick.
 
I just went out and checked. There is a plate there but no stick, or even a hole for one?

i called the last owner and they said it doesn't have one? hes had the tractor for 20 years

I don't understand, how can I check the oil level,

If i look down the plugged hole next to the shifter, i can barly see the oil?
 
Right hand side when seated , behind and below the quadrant lever . There is a round plate there that is the size of a saucer and would have had the stick in it . Sometimes there is a hydraulic return line put into it instead . To check the oil level remove the lowest bolt from this plate , oil should just seep out if it is at the correct level . The dipstick mark is at the same level as the lower edge of this bolt hole. If it's low add oil into the gearbox filler slowly , it takes a while for the oil to make it's way back to the rear .

Don't worry about that low level it does look weird from that filler . The oil gets flung about by the gears and lots gets splashed about to lubricate things . The flat plate you have is obviously a replacement . Try the bolt trick I mentioned to check the level .
 
The oil level should be right at the bottom of the round inspection covers. It is not critical to have it level full, down a couple inches is no big deal. Overfill it though and oil will dump on the clutch!

Those are notorious for collecting water in the transmission case. It gets in around the shifter boots and the upper link boot under the seat.

Bad news though, the jumpy hydraulics means pump valve trouble. There are spring loaded input/output valves in the pump. The springs and valve stems break, causing the pump to loose volume and making for erratic flow, causing the jerky effect. The pump will need to come out and be repaired or buy a rebuilt pump.
 
Thanks for the info guys,
I went out and pulled the lower bolt. I stream came gushing out. so i would say its over full. i might as well drain it and replace the fluid.


Would a pump rebuild be hard? are there rebuild kits available?
 
PS:

If you do pull the pump (it comes out the top, best get a manual first), you'll want to swab out the bottom of the sump, it will be nasty.

The original oil was 90 weight mineral oil. That will work in warm weather. If you are in a cold climate or plan on using the tractor in cold weather, best sub 15w40 engine oil. Otherwise the lift will move very slowly until the oil gets warmed up.
 
There are rebuild kits available. I bought one several years ago, it was close but not right. Had I not had access to a surface grinder and a mill, it would not have worked (Chinese aftermarket). I would recommend taking your pump out, look it over. If all it needs are valves, fix it. If it has other problems, get a rebuilt pump.

But wait on the oil change, otherwise you will have to try save the new oil.
