## Questions & Answers

**Q: Does this separate to take off around connecting rod when doing a top end rebuild?**
A: This item will come apart into a metal strip. Depending on the type of machine you are rebuilding, when I build chainsaws, I have better security with using piston ring remover during disassembly after piston is removed. When installing I use ultra engine assembly lube and use my fingers to squeeze ring/rings together one at a time when installing into cylinder.this method has proven much easier.

**Q: How tall is this tool?**
A: It is 1.756 Inch or 44.61 mm. I sent two photos about product measurements.

**Q: need the height of the compressor, cant be over 3" thx**
A: I went and measured the one I purchased and it is 1 and 3/4 inches tall.

## Customer Reviews

### ⭐⭐⭐⭐ Four Stars
*by C***E on February 1, 2015*

Very good but a little stiff for a chainsaw piston.

### ⭐ May work, but also may ruin your day.
*by J***K on November 2, 2015*

save your money elsewhere. It did the job about 4 times, but I hated every minute of it.I work for a small engine manufacturer and I build/maintain race kart engines. This was not user error. The cheap nature of the tool makes it susceptible to sliding in with the piston. The higher end tooI now have has a nice lip to prevent this. Spend a few extra dollars, save a few knuckles and frustration.

### ⭐⭐⭐ Three Stars
*by J***S on April 14, 2015*
