## Description

Lisle 33500 Piston Ring Installer

Review: The Lisle 19500 Ring Compressor worked well for reassembly of a Honda lawn mower engine. The clutch-type latch allows finer adjustment than similar ring compressors that use a ratchet mechanism. When I purchased this (and still at the time of this review), the item description says the 19500 Ring Compressor's country of origin is China but both the packaging and the item itself say USA which was a welcome surprise.
Review: Works really well, have installed rings on 383 sbc pistons now and on a set for a Lq9 with forged Pistons with no issues, makes getting the rings on way easier and they seem plenty durable enough to use a lot of times.

## Questions & Answers

**Q: will it work on a honda b17 ?**
A: Yes

**Q: Will it work on a Yamaha pw80?**
A: Should work for small engines

**Q: Will it work on chain saw size (+/- 40 mm) pistons?**
A: No

**Q: Will these work on a small engine like a tecumseh H70?**
A: I am not familiar with that particular engine but I assume it is a very small bore.  I used this tool on a BMW motorcycle with a 94mm bore and it worked great.  Years ago when I had McCulloch go-cart engines, I installed piston rings by hand
