Review: Ring compressor - Worked great on small engine 80cc motor cycle
Review: Very handy accessories! - I didn’t see a need for these because I could slide a cylinder onto a piston fairly easily, but after using one of these for the first time I was blown away with how much easier it is. Fantastic tool! And the added piston stops are a good touch as well

## Questions & Answers

**Q: What is the purpose of the black and the white pieces?**
A: Stick in spark plug hole to lock piston

**Q: Would this kit work to install piston and new rings on a 4 stroke Honda 90 Motorcycle engine ?**
A: You don't need a ring compressor for motorcycles. The cylinder itself has a bevel on the bottom of the cylinder to gently compress rings as you lower the cylinder onto the piston/ring assy.

### ⭐⭐⭐⭐⭐ So easy even a Neanderthal can do it
*by D***E on June 17, 2020*

I bought this thinking it was a stupid way to put a piston in a cylinder with rings. I'm a metal and chrome guy at heart… plastic? PLEASE! OK first, I was WRONG. The flexibility and spring of the plastic compression rings is perfect. Once I snapped the rings into their place on the piston (Reminder: 2 cycle pistons normally have a guide pin the gap in the ring goes there AND it makes a difference which side of the ring is facing up… . the top of the piston). A common mistake by most novice motor fixers is to put the rings on upside down. When that happens, they'll never get the cylinder to slide onto the piston… (voice of experience). Pre-lube every surface (including the roller bearing and the crank main bearing areas, so they don't create extra wear on assembly AND on initial start up. Step 1: slide the funny looking rectangular thing with a slot in it (piston stabilizer) onto the connecting rod and under the base of the piston. Then, rotate the motor flywheel until the piston is resting on top of the stabilizer block. Step 2: Pick the correct size ring tool for your piston (up to 60 mm) and wipe it down with a lint free cloth. smear a little bit of oil on the inside, squeeze it around the top of the piston, compressing the rings into their slots. Step 3: Pick up the cylinder assembly (if it's a Husqvarna 395XP put the carb on before you do this makes a big difference in your later steps), align the base of the cylinder to the piston and slowly slide it down onto the piston. You'll hear a click if you misalign the cylinder and rings as the ring snaps out of the slot… DON'T FORCE IT! If that happens, and you see the ring sticking out of the slots in the piston, STOP. lift the cylinder off and start from Step 1. The guide is just slippery enough but tight enough to slide down the piston while you're pushing the cylinder and controlling the rings. Would I buy this again? YES Is it a good bargain? Heck YES
