170 Allis oil leak

My 170 is leaking oil at the end of the 3point hitch rock shaft. How hard is this problem to fix?

Looks like the lift arm is splined to the rock shaft and held on with a snap ring. Is that spline a press fit. How hard will it be to remove the lift arm?
 
Not too hard of a job. Arms slide off after removing snap ring. Will require replacing the seals and probably the bushing in the housing also. Depending on how your rear wheels are set, it may be a challenge sliding the rock shaft over enough for repair.
 
Bill, Thanks for the info. I gather the rock shaft will slide sideways once the lift arms are removed. My tires are wide enough to get the arm off but maybe not to pull the bushing. No big deal to remove the wheel.


Wish I had a cross section of the rock shaft assembly so I had some idea about how to pull the bushing. Is there a shoulder on the bushing to rig a puller against? I have a repair manual but it does not cover the rockshaft assembly.
