yup the 2 upper ones in photo are the rockshaft...just use an appropriate size punch and hammer. never removed that style of rockshaft before but heard your in for a rough time as the peices dont like to slide on the shafts. it will help if you can remove paint from the shaft so the arms can slide

You are going to need some punches. I got both sets from Harbor freight when I dissasembled a 125. Sometimes you need a short one, sometimes a long. The $18 for both sets was well spent.

Just so we don't get too deep into tools..... she stated in her last thread that she has roll pin punches.

Yep, rockshaft is the top one in the pic.

Now that you mentioned that, I read through that thread and indeed she did say she has many tools from her late Husband.

THANKS..now..do I approach these pins from the side that shows in the pic, or from the other side? I am not dumb, just have not done some of these things yet. I learn by doing.....and asking questions

You can drive them out from either side. Want to drive them from the side you can get the best swing from a hammer. I'd go from the pic side if it were me. They still can be a pain to get out. Also check to make sure a PO didn't hit on one end with a hammer or punch. May have mushroomed that end and it will be hard to drive through the rockshaft. Good luck and keep us posted.

Thanks, and I will keep you posted.

If you can, you may want to grind/file the end flush w/the shaft.
That way as soon as it starts to move you can get some WD-40 or something like that in there to help loosen it and also avoid mushrooming the end. The correct punch will follow it right through the shaft.
I assume you are going to replace them anyway w/new ones.
BTW. why are we/you removing them ??
Be carefull!!

Thanks. I am removing them in order to replace the rockshaft assembly.
I lost lift last year after I attached the 451 thrower to the 982.
Apparently I either attached it incorrectly or the pins were ready to let go and just needed that straw that broke the camels back. I have lift action under no load, with load, my blade, I am lucky to see 1" on the R side , and 1/2" on the left.
