| I've been trying all day, more precise than ever in my life, yet cannot get them into cylinder liner. Using standard piston ring compressor. Is there a trick? This costing me days of futility. Thanks for any ideas. On 271 engine, GM Diesel, two cylinder, 1951 |

Try a ring set, alone, sans piston. You may have the wrong ones, or they might need fitting... ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |

you maybe saying the same thing, but remove the rings from the piston and see how they fit in the cylinder. there should be some gap in the ring ends when installed in the cylinder bore.

| I finally figured out which control ring was the chrome. They all looked the same. The diagram in the package showed slotted and non slotted, I think I've figured that out although they seem very close to the same. Had no idea this was literal rocket science. The kit also has main bearings that I don't think I could install or need, but now I see it may be possible with the engine still in the tractor. It's starting to osmose to me these four halves of "thrust" bearings. I have no idea how difficult they may be. This whole process has been a scary gamble. Will the end ever come? |

Are you loading this from the BOTTOM of the Liner? The bottom lip is relieved for ring entry, the Top is NOT. Pistons/Rods and Sleeves are assembled to these engines as a Unit not individually. I used to own sleeve loading units as this, made life simpler for a mechanic. https://www.youtube.com/watch?v=T9nlfXMO88o" rel="nofollow - https://www.youtube.com/watch?v=T9nlfXMO88o

| Very easy to break oil ring using regular compressor even though going in the tapered bottom |

Yes, I already have broken some and got new ones. When you say regular compressor, it seems I need an irregular one. What might that be? |

| Need to make absolutely certain a wrap type compressor is square and not barber polled when install piston, has to be in full contact with sleeve until rings are in the bore. |

The compressor you need is in that video link. Find a truck shop that still has one and take your stuff there and pay them to load your liners |
