Mahle MS Clip Insertion Tool for .927 Clip

Works great

I like it wish it was aluminum. I'd pay 4x more then. If you have low hp/rpm/diameter clips it's easy. If you have big boy springs helps to have a buddy. 1 guy pushes down w/ finger & uses polished edge screwdriver on the outer end of the spring. We thrashed one but got 1/2 way done. Practice staying in the hole b4 you do any of them. Small circular motion. Videos online are baby clips. Mine are massive.

This tool might be good if you buy the metal version, but the plastic version wears down right away. Only worked for one circlip before the plastic was worn away. Spend extra and buy the metal version...

Worked like a dream. Watch the video on the website, it takes a minute to get the hang of it. I wish the plastic was harder so the tool would last longer, but I think I can probably get a couple sets of pistons out of it.

This tool did great once you get a hang of the rotating motion to get the clip in. You do lose plastic material each time so make sure to clean the piston pin area off. This one lasted me 8 pistons, some were like butter and some not so much. But this beats using any tools that may badly score the piston or pin. If I had time I would machine this out if aluminum. Once I finished it was almost a smooth nub so went in the trash after. Chuck it up as a cost for assembly
