How to change the chuck on an All American 225 Can Sealer
Today we are going to demonstrate how to change the chuck on an All American 225 Can Sealer, one of our most popular can sealers. This tutorial will show you a detailed guide on how to change the chuck and make adjustments for different can sizes. For the purpose of this tutorial, we will be changing from a 3 oz can sized chuck to a 6 oz can sized chuck.
Remove the base plate and washers
The first step is to remove the base plate and all washers you have placed on the shaft of the 225 Can Sealer; by doing this you will have plenty of room to continue the task.
Move the adjusting rivets
The next step will be remove the adjusting rivets and place them on the furthest point of the sealer. For the All American 225, we will be moving the adjustment rivet to the number 3. Do this on both sides of the sealer so the seaming rollers are out of the way while you replace the chuck.
Once this step is complete, you should see both seaming rollers open wide and you are now ready to remove the chuck that is currently installed.
Remove the chuck
Now that you have the space to remove the chuck, place your thumb in the gap and begin to gently wiggle the chuck while pushing down. You should feel it slowly start to come out of the canning machine. Once you have the chuck removed, place it aside and grab the new chuck you want to install.
Installing the new chuck
We are now ready to install our 307 chuck which fits 6 oz tuna cans. The shaft has a flat edge on it which you will need to line up inside the machine when fitting the new chuck into place.
Push the chuck into place gently until it won’t move anymore. At this point you will have to slowly rotate the chuck until the flat edge finds it’s groove inside the machine and fits in tightly.
Adjust seaming rollers for new chuck
Now that the new chuck is fitted, we need to adjust the seaming rollers for the new can size. As mentioned before, the new chuck we are using is for 6 oz tuna cans which matches up with the number 2 on the rivet holes next to the seaming rollers. We will be moving the rivet from 3 to 2 in this step, on both seaming rollers.
Re-installing the base plate and washers/shaft
The final step before you can start canning is to put the base plate and shaft back into place. Due to the change in can size, we had to remove two washers from our shaft to fit the new can size on our chuck. T
The correct amount of washers will fit the can snug while causing the bottom spring to compress slightly.
Once this is done, screw the base plate back on and you’re ready to start canning! Thanks for checking out our guide on how to change the chuck on an All American 225 can sealer.
