    Ring Compressors

    Im interested to find out what ring compressors you folks are using...pros and cons of each. Theres a big selection on Ebay and am looking for suggestions on what kits are efficient and which ones to stay away from. Thanks.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      For the bike, I carry my ring compressors with me ALL THE TIME.

      Sometimes they are in my pockets, but they are ALWAYS at the ends of my hands.

      Yep, I just use my fingers to coax the rings into the tapers on the bottoms of the cylinders.

        Yep, fingers are the most sensitive and least likely to do damage. I've been known to increase the lead-in tapers on bored cylinders too.
        Some reconditioners don't give you enough taper after boring.

        Very late engines - non GS - with Nikasil bores and the barrel in unit with the top case present their own version of this problem.
        Often the top edge of the bores is a sharp corner - no lead-in taper at all.
        I've been making up bolt-on plates with the taper included and have found this to be very satisfactory.

          If you're working alone and using fingers it take a lot of patients to install the pistons/rings safely. A couple of tricks that I've had success with is to block up the cylinder and then nudge the pistons up into the bores by rotating the crank. A better way is to suspend the cylinder using a bungee cord which allows you to slowly and uncontrollably lower it. Check Salty Dan's thread for a photo of such a setup.

          As for ring compressors, I've seen guys using simple band clamps and others band clamps after wrapping the pistons/rings in thin metal shim stock. And of course there are all kinds of commercial spring compressors as well. I'd go the commercial route if doing it for a living. Easy for me to say though since I haven't priced them lately. Can't imaging them costing too much though.

            I was a fingers type. Last time I cut 2" wide strips from a plastic food container and used jubilee clips to squeeze the rings.
            Maybe I got the plastic thickness just right. It went just far enough into the flare, the pistons practically walked in.
            Like Ed said, I rotated the crank to the pots.
            The only downside was that when the hose clamp came off the plastic wanted to spring out and take a swipe at the base gasket.

              I’ve installed hundreds of cylinders over pistons using my fingers and never had a problem. Then again I know how to use the factory tappet depressor without any problems, have installed hundreds of heli-coils without a problem, and I know how to use easy-outs and taps without breaking them. Some people have a good feel for working with their hands and some people don’t.

                I got hands like bear paws and fingers like sausages. I been using smalll blade screwdrivers to sneak them into the bevel. Just think its time to make things easier on myself.

                  I used hose clamps on my last re-gasket job. Just made sure to sand the insides with some 400 grit to remove any burrs and oiled them up before installing them over the rings. Worked easy-peasy for me!

                    After almost 40 yrs. doing this, Dar got it......... You need to have that feel,,,, that only experience can provide......Back to ring compressors I have used the band type with decent results..I usually tapered the bores more,,That helped a lot.......

                      I just use my fingers.Band type are easier to remove.You will need at least 2 set.
