GREAT PRICE AND PROMPT SHIPPING.

Works great for small engines

Great ring compressor tool and ring expander tool made of high quality materials.

This ring compressor does work but the tension screw region tends to bow out a little bit so you gotta be careful when putting in pistons with this tool to not break a ring.

This ring compressor worked very well on 3.25" pistons. The locking mechanism worked very well even on the tightest compression of the rings. I only did 4 cylinders but so far very nice ring compressor.

Una herramienta genial muy buena de verdad

This thing is HOT garbage. End of the band won't actually pull into round behind the ratchet mechanism, so the rings aren't actually compressed against the piston.That people are giving it 5 stars and saying it works is legitimately mind-blowing.

I think this would probably work fine with bigger pistons on larger engines.However, on smaller 2 stroke engines (like my B&S 3.5hp) it does not work.The extra metal is rolled up on the inside and causes it to deform and not fully compress the rings. It makes more of an oval shape.Plus, there is no real way to grip it to get it to really cinch down tight. Really frustrating because you should be using an assembly lube, so you are already fighting a slippery situation.My recommendations to the company is a handle and a possible way to use a ratched instead of the square tube angle wrench they give.The old fingers pinching each ring in was actually easier for me, so good luck if you purchase this.Just not for me.
