Pin and bushing front drawbar support

[8850dave]

How is the bushing and front pin replaced on the front of the drawbar frame, I see a 1/4 roll pin but does it drive out ? Replacing leaky seals on a 71 4020 power shift ,
new shaft and bushings no idea on the actual hours on tractor

It's common to leave it alone and just drop the rear of the frame to replace the load seals.

Just drive the pin out. The roll pin holds just the bushing. The pin can be hard to get out. Like Connie mentioned most just pivot the carrier down leaving it on the front. You might want to take a look at how worn the holes are for the drawbar pin. I had a 4020 that would pop the pin out sometimes when on a single axle manure spreader. The holes were very egged out. Deere had bushings for the top hole. That stopped that problem. Tom

Replace the front bushing and pin. They wear out.
When they are worn out it, the load shaft will flex more than it is suppose too and you will have an oil leak as you have seen. The pin is designed to stop the load shaft from flexing once it has reached the maximum flex point.

Do you heat the castings before driving out the pin as mine has not moved yet and have heated it as well going to try an air hammer after its heated up again
