Does anyone have any easy ways to remove a frozen rocker pin. My rocker is broke, and the eyelets where the pin goes through are wore out bad.
I have heated it, and hammered on it, but it won't budge. Now I need a new pin also.
Pat

Diamond blades aren't that much money.

Mine was stuck bad. Wheel removal not an option. Tried cutting with a sawzall, maybe the pin was hardened, it didn't work. Tried hammering, tried pneumatic hammer, nothing worked. I used Kroil, but don't have acetylene.

What finally did work was clamping a 6 ton bottle jack and a piece of round stock on one side of the pin, a pipe coupling over the other side of the pin, and heavy angle iron welded square around all of that for the bottle jack to react on. Came right out.

You could whiz wheel the rocker off before driving out the pin.

I remove the wheels so that I can wail on it from both sides with a 4+ Lb. hammer and piece of hard brass. Don't get carried away with a sledge hammer or you might break the differential casting.

They can be stubborn but they will come out.

Had the same problem on a 641 that was left outside

for 30+ years (uncovered). My top link socket was also

broken off like yours.

To speed up the process I drilled a small (1/8 hole)

in the middle of the rear casting to allow P blast

to get in and work. It took 2 weeks of constant spray

of lubricant before I noticed that I could beat the

pin a little. At that point I hit it back and forth till

it came out.
Pin was completely salvageable in my 821 rear end.

And son in law welded TSC collar in place of the

broken top rings. I didn't want to spend $100

for a new top link rocker.

I figure I can add a grease fitting into the hole for

future lubrication.

The only easy way that I'm aware of is to take it to dealer - They do not like to come apart.

Kroil, heat & beat is the most common method of removal.
A stout air hammer may help.
