Need help I have a 180 that pumps the hydraulic oil out of the transmission breather on the top of the transmission every time it is filled ? I have changed the oil and filter and it keeps losing the Oil out the breather? When the oil is full the hydraulics work until it loses the oil.

Shift the Power Director lever into neutral or LOW range and if the problem ceases or is improved, the oil seal behind the Power Director clutch (transmission input shaft) needs replacement.

The reason it needs a seal, is because the piston ring seals on PD are worn out and maybe the housing they run in. MACK

Tractor has to be split in two right where you check your hydraulic oil level.
