|

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.

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. |

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. |

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.

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. |

Finally warm enough to work outside again. I drilled a 1/8" hole into the back of the rear end housing into the rocker pin today. I put some PBBlaster into the hole, and on the sides, again. I then came back 20-30 minutes later, I hit it with my small maul, and it moved. I got it out. Now I have to rebuild the rocker some how. Since it's cast steel. I can weld on it. I'll see how it goes.
Thanks, Pat |

I bought a $24 pack of cast weld rods
from TSC and my S-I-L tried
welding the TSC collar. WOULD not
stick to collar. Finally had good
luck welding with standard steel rods.  |

The rocker is not an item that I would attempt to stick weld an I am a certified welder. Maybe TIG but for your safety, I recommend finding a replacement rocker. |
