PTO Shaft Leak

steve terplak · Sep 19, 2013

I have a landini 105, 2003.
I noticed, yesterday, after coming in from baling that there was some hydraulic fluid beneath the pto shaft.
At first I thought a little hyd oil had leaked when hooking/unhooking hoses but I don't think so.
Busy day, did not get a chance to look too hard but it appears to be coming from the bottom of a cover around the shaft. There are 3 bolts and it looks as though there is a gasket underneath the plate.
Is it probably that gasket? if so, what is the replacement process?
What else could it be? I have an owners/operators manual but not a shop/repair manual.
Thanks guys.

Hi
Is that the same back end as a 2002 Mythos 110 by any chance. I had a customers tractor here I found it had 2 leaks on the upper pto shaft.

One was the speed sensor was cracked on the threads under the lock nut, in the bottom of the pto housing. oil was weeping out the crack. I changed the sensor and half the leak went away.
The other leak is the seal on the outside end of the pto shaft. I washed the rear end. Then ran the pto.

The oil pooled in the gap between the shaft and the threads, where the cover screws in after a few minutes running.
Then it flows over the lip and drips down and under the housing. With the pto housing being a dark brown color for some reason on this tractor, it was hard to find the leak while dirty.
I haven't done the seal leak yet guy needed the tractor back.
Like you I need to know how it comes apart. Before doing something wrong, and causing more problems than this tractor has already had breaking down recently!
