I found this site when me and my grandfather started to work on his 1957, 520 and realized the plethora of information available on this site about these old two cylinders. Just last week we went in to do a "simple"

pto clutch job. Then found out the oil seal was leaking transmission fluid into the case also decided it was a good time to fix and reline the brakes. And this is where we are now, hopefully if we can finally get one brake adjuster loose and the adjusting pins she'll be going back together tomorrow.
