Mike's CB550 Project
Nurse Julie:
Both the plenum vent tube and tube from the airbox can be a length of open ended tubing Mike. Most owners only fit the OEM type if they still have them, the rest of us just use tubing and they work perfectly.
Mike_Berkshire:
Thanks to help from the forum I now have all my O rings identified and sorted, the oil control valves clean and the cam chain tensioner adjuster nut running smoothly on the adjuster stud. My mate is coming over at the weekend to help me put the top end back together (an extra pair of hands as opposed to any more experience than I have). One of the tasks that I am concerned about getting right is locating the bottom end of the cam chain tensioner assembly in the right place.
Can anyone give me any advice as to how to ensure that this is fitted correctly? The engine bottom end is in the frame; not on a bench/stand.
Thanks, Mike
Johnny4428:
Make yourself familiar with the location of where the bottom end of the tensioner arm sits before you put anything together then when you have fitted it you will be able to shine a light down the camshaft chain tunnel to view whether it is in the right place or not.

I had a go at that today Johnny and I couldn't see much peering down into the crankcase even without the barrels in place. from what I could see there is an angled tang down below that the tip of the tensioner slides against and into it's 'pocket'. I guess if I can see this tang when installed then I am on the wrong side of it? Or maybe I wasn't seeing clearly; I have had a look in the parts book to see if that helped but couldn't see anything. Is the pocket it sits in machined into the case itself?
Sesman:
Mike, also try checking by looking via the sump plate.
