    How to Install Cylinder Block

    From all the racket coming from the top end of my 1100E, it looks like I'll need to do some investigation of the chain guides. I've built Harleys and BSAs but never an inline four. Is it necessary to get a set of 4 ring compressors to reinstall the cylinder block or is there a more clever method that's not a complete PIA?

    You can buy proper ring compressors, or use whats handy, I use hose clamps. 2 pistons go in at a time so you only need two.

      I use my fingers to squeeze the rings rings tight. Do the inside ones first (cyls 2&3), then the outside ones (cyls 1&4).

        As mike states, you can do it with your fingers but you need to be really careful. I block up the cylinder and then rotate the crank up into the cylinder thus controlling the force applied to the rings. If you drop the cylinder down it's easier to damage a ring; lots of guys break and/or bend a ring when installing the cylinder down so please be careful.

          I've used hose clamps too. Works ok.

            Are you sure of the problem?

            These DOHC motors are much noisier than the push rod motors you've worked on

            I'd start with the cam chain tensioner service and see what that does

                I just knew Jay was going to say that.....I always use wooden clothes pin pieces. Nice soft wood. Tip the piston to start one side, then use the wood and the taper to ease it into the hole.....Billy

                  Thanks for the input gents. I like the clothes pin method. Simple but effective. I'll make it a point to skip the beer until this parts completed.

                    Wood is always good for working on soft metal, what I usually use for cleaning off old gasket too. I tried the clamps and other stuff and ended up mostly working them in by hand. It wasnt too bad cause I had 2 people holding the block for me and I just focused on the rings.
