33500 Piston Ring Installer

I can't believe I went so many years without this product, putting piston rings on by hand. This tool makes ring installation an absolute breeze.

Ok, just for reference, the last time I did a ring job was about 25 years ago. But it's that time again, and this time, I sought a ring expander to avoid the problems with using your fingernails to put the rings on. I looked over a number of modestly priced tools and found this one. It works as advertised. Honestly, I found a few others that appeared to be pretty much the same for a couple of bucks less. I bought this one specifically because it's sold by a family business in the US - the Lisle corporation. The package says Made in USA - I can't tell if that's the tool or the package - but in any case, I'm happy to spend a little more to support a local business. Upon further inspection and actual use, I think I can put my finger on why this is better than other products that might look the same. That's because of the quality assurance that Lisle seems to provide. When you're expanding piston rings, everything has to be lined up just right or the ring will twist. For those who understand geometry, I'm saying that the tool and the ring all have to be on a plane - to be perfectly flat. I took a good look at this tool in that regard. First, the hinge is perfectly aligned - there's no play or slop, but it operates smoothly. Second, the jaws - the part where the tool meets the ring - are perfectly aligned. The result is that you can expand the ring smoothly and without it twisting. One hint is to be gentle when you're expanding the rings. You don't want to expand them any more than necessary to get over the piston. Take your time, and this tool will do its job for you.

Really easy to use and seems to be made pretty well. Made doing my job very easy and cost effective.

A bit flimsy but they work ok if you are careful.

Perfect for installation of exhaust flange rings!!

Best buy

never used one of these before. Sometimes a project can be accomplished without the right tools and sometimes its all about working smarter not harder. This tool accomplished that, took seconds to get the rings out of each piston. Made a pretty simple job a quick job.

Worked for what I needed it to do but I dropped them once when I was going to put them away and The spot weld broke so I ended up throwing them out

Tool जैसा दिखाया गया था वैसा नहीं है बहुत बेकार टूल है इसको मत खरीदे असंस कंपनी की जितने भी टूल होते हैं सब बेकार होते हैं बिल्कुल ना खरीदें lisle कंपनी का tool दिखाया गया था लेकिन दूसरा tool दिया गया है मुझे बहुत बेकार लगा

Simple and works

Buena calidad

The piston ring pliers work fine :) They did the job that they was purchased for But if I had it to do over and knowing what I know now I would have purchased there adjustable set

Nice tool, works perfect and very affordable.
