I see a special tool is needed to remove the ACR on the 103 head.

Looks like a little grinding on a deep well socket will work.

Anybody know what size socket is used??

Manual don't say...again

One of the tool mags shows 7/8ths, we'll give that a try.

 

Mine is a 13/16 deep well, 12 pt socket with a slot cut out the side, similar to a O2 sensor socket. It needs to be fairly thin walled socket, because the clearance is pretty tight.

 

13/16 socket and a dremel tool and you're good to go

 

Interesting, I notched a 7/8th socket and it worked well..go figure

Not sure why it worked on the first ACR I removed, but ya a 13/16ths is the right socket, not 7/8ths.

because when you cut the socket, it spread. for the life of me, I don't understand what is the aversion for buying the right tool for the job. its not expensive, it works perfectly with no chance of collateral damage, with a little planning (order it ahead of time of the job) there is no time loss of modifying an existing tool (which now will need to be replaced) that really may only work once. just buy the tool, if you needed it once, theres a good chance you'll need it again. people spend tons of money on needless crap that will be thrown away in 6 months and a tool will last a lifetime

 

Why would I buy a 40-50? dollar tool to use once when a $3 socket and a bit of grinding works just as well?

I now have $3 and about 10 mins time invested in a tool I'll if all goes well, I'll never use again?

I picked the wrong size socket because of not being able to see/measure the ACR in place, so I guess I have $6 dollars invested.

Were I making my living working on bikes, I might tend to agree with you, but as I'm building the bike once and don't work on others, I see it as a waste of money.

The socket did not spread, the first ACR was in only just past finger tight, the second one was tight, more of that HD quaility assembly procedures I guess.
