How do you get the old inflations off the metal inflation holders and put the new ones on? Probalbly not the right terms, but Im new at this. Mike

Where the skinny part comes through the shell there will be a ridge that holds it in place. Using thumb pressure push the ridge in and up into the shell. May take a bit of pressure. Once the ridge is all loosened you can pull the inflation out. If you get really frustrated they can be cut I suppose.
To install push the inflation into the shell, grasp the skinny end firmly in one hand and the shell firmly in the other and pull until the ridge pops out of the hole in the shell. Make sure the large end (where the teats go) is in place around the rim of the shell.

Just like he said, twist and pull takes only minutes to remove the old and put the new on.

Used a butter knife. Worked great. Thanks for all the help....

Make sure you have the new ones lined up. At the top of the inflation, and at the bottom there will be two marks. Usually a raised part on the rubber.

The two marks need to be in line with each other. If they are not lined up, they will have a shorter life, and do a poor job of milking.

Once they are lined up, they will not stay that way, you will need to check them time to time.

I replied to this but it got lost in the problems Dean had to fix up. Let's see if I can remember what I wrote

After years of changing hundreds of the things, I got sick of wrecking my fingers so now just cut them off at the ridge Sammyd mentioned and pull the inflation out that way. Insert the new inflation and give a firm tug to pull it through the bottom of the cup ensuring the top fits snugly over the cup. To attach the inflation tube to the claw I soak it in boiling water for a couple of minutes and it slides on easily.

As Trav says, make sure that everything is straight - if the tubes are twisted the cup will twist on the teat which is uncomfortable for the cow and causes slow milking.

Cheers,
Ronnie
