Worked fine on a 3406b
Works fines better one one than the other but made 3406b pistons in new liners easy

Broken rings
This is the biggest piece of junk. It comes with the rings stuffed inside the anti polish ring adapter and damaged it. The compressor itโs self doesnโt even compress the rings enough for them to start inside the anti polish ring adapter. As a matter of fact the adapter is a good .100 of an inch smaller and you will break every oil control ring you have trying to make it work.

It will work but needs some polishing
Anti-polish ring adapter out of round and wouldn't fit the liners, the removal tools (giant snap rings) were shoved inside the adapter and had left gouges, ring compressor too tight not to mention the fit and finish on the machining was pretty poor, had to spend a few hours in a process of polishing and test fitting to make everything work but eventually it got the job done. Would have been worth it to me to purchase the OEM tooling with what I lost in labor time, but if you have the time and patience to work with this tooling it'll get you there eventually
