Serial number 6144001 1960 or 6162601 1961. Case 430 standard front diesel. Like to knwo where to get a manual? Also I need help. The trouble I am having is I'm losing almost all of the transmission oil from the transmission and it seems to be going into the rearend. This happens after I lift the blade or the bucket on the tractor only up and down 3 or 4 times. Causing the hydralics not to work anymore as there is no more hydralic oil in the transmission. There is two dipsticks on the tractor and when I check the dipstick for the for the transmission the oil dosen't show on the dipstick. But when I chect the dipstick for the rearend it shows a way over full. Some people told me it might be a seal but they didn't tell me were the seal is located. Rick Jensen canada
 
The seal between the rear end and the rockshaft seal will puke oil into the rear end. This is common on these tractors.
 
seal between the 3 speed tranny and the main 4 speed is out tractor has to be broke into 3 speed has hyd in it the main box has 90 weight. fix several over the years. tom.
 
hay ,, no one really clarified , I am confused from reading responses and I am fairly sure I know the problem , so you probably are too .,.. , I think the seal in the 3pt hydro ram under the seat is the culprit , you mentioned a few lifts and all oil is migrated to rearend overfilling it ?this is usually the cause ,, take the plate off and have a good hydraulic man replace the seal ,, I have done 3 in my time and everyone I musta chipped they are a buoger to get rite
 
The 3pt piston seal is bad. Pull the rockshaft housing off. (tranny cover under seat). slide the rockhaft out and remove the piston, and you will find the culpret. I have never seen the seals between the compartments to be a common issue, as two posters have stated.
