Discussion for the Milwaukee 6521-21 (SER 981A) Sawzall
Hey Bubbajames,
The parts kit comes with step by step instructions..it is somewhat difficult but once you have done it 2 or 3 times till you get it right you will become quite good at it..ugh:)
Hope this helps..

Im trying to relapce the 45 ring gear on a 6521. I grabbed the gear w/ pliers and used a wrench to spin the lock nut, but the shaft just rotates with the nut while the gear remains gripped in the pliers.
Help
Hey 206benji,
That gear is actually replaced as a assembly now..[with the shaft]..part #32-40-2104..be sure and check your serial # to make sure it matches up..:)
parts avail at ereplacementparts.com..
hope this helps..

Thanks, I looked at the diagram and saw the gear assembly is sold as a complete unit and figured I would order that. However, how do I get the old one(s) out?
( I have two that need replacement)

At the other end of the shaft,there is a nut that has to be removed..if you pop out the plastic or rubber insert at the end of the housing you will be able to access..as far as the other gear [on the eccentric] there are detailed removal instructions at link removed..
kind of a pain...:)

yes, I put a wrench on the lock nut at the other end of the shaft and use large channel locks and rubber hose to hold the gear, but the shaft just spins with the nut. grrrrrrrr

Ugh..
I'm not sure but it may be a reverse thread..so try loosing it the other direction..? They are on fairly tight also so you may have to really lean on it...:mad:

use a cordless or electric or pnuematic impact wrench to take the nut off, the torque on the wrench will easily remove the nut
Anybody know how much of the tip of the wobble shaft should stick out at the top after pressing on new gear and it's corresponding disc spring and washer?
The last page of the breakdown in the PDF version has repair notes including the specs on pressing the gear onto the shaft. You can find the file at the following link...
