c-mac Posted May 28, 2016 Share Posted May 28, 2016 (edited) I just pulled the 6 copper cups from an 07 MP7. The last one left the tip in the head. I was using the puller that grips the larger area inside the cup. I have replaced many sets of stainless cups on mp8's. Any ideas on getting the piece out? I have the correct Mack tools to Install the new stainless cups for an mp8, Do you use the same tool to swedge the stainless cup in the mp7?

Macktech689 Posted May 29, 2016 Share Posted May 29, 2016 You will need to find the old tools that tapped the small diameter of the sleeve and the puller to get it out, not a big deal the get that small piece out. The installation procedure is the same for both 11 and 13 liter engines.

steeler Posted June 3, 2016 Share Posted June 3, 2016 As 689 said, the old tools with the tap and puller is the only way you're going to get that out. Unless your luck is like mine. I broke one off in a d12 because I got lazy and didn't get it tapped all the way through. When I tried to tap it the rest of the way, it fell into the cylinder. Had to pull the head.
