I am starting my first rebuild of a Oliver 1650. the brakes housings were full of oil and water. after getting the brakes removed I have tried with no success to remove the housing because I need to replace the seals... my manuals are vague and of little use on how to remove the housing. does it simply pull out? is there a trick someone could help with? thanks in advance..
