Hello,
I just joined the forum, a bit of help please.
Ferguson TEF20. Valve seat inserts. Anyone know how to remove them. Can I get replacements and from where.
Your help would be much appreciated.

An automotive machine shop would be able to replace them, they are pretty generic.

Unless you have the equipment to do head work best let the pros handle it. That's an exacting process, get it wrong and they will fall out.
 
If the old one is still tight, they cut it out.

If it is loose it will be pried out or lifted out if loose enough.

Then the head cut to the next oversize to achieve a very tight press fit. Even doing that the replacement seats sometimes come loose.

Traditionally, dry ice has been used to chill and shrink the new seat for installation, I see Goodson now has same stuff in an aerosol can to do that.

They also have replacement valve seats.
