TC 33D Hyd leak from weep hole

scalesusa · Apr 18, 2025

My TC33d has hydraulic leaks at weep hole, it loses a lot of fluid. I saw a post where someone thought that o rings might be bad on tubes in the area, but no resolution. I wonder what could cause this. It does seem to be worse when using the loader.

Has anyone fixed this?

Looks like you will need to split the tractor to find out. If not doing it your self..yes its expensive.

Need to identify if it is engine oil or transmission oil. if engine oil , then it would be from rear main seal on the block. If that is the case then it might get on clutch and flywheel if you have manual transmission. This can cause slippage of clutch. If it is transmission oil, then transmission front case seal is leaking.

At any rate, this is not a good occurrence as repair needs to be done starting with a tractor split unfortunately.

Unless he just changed his engine oil it wouldn't look like that. Even if he did it would most likely be darker than that already.

I was making a general statement on the methodology to diagnosis. Can take the dipstick out to get a whiff of the oil on it. Doing the same with transmission oil to compare and contrast.
