I am new here so I thought i would introduce myself and my new project.
By day I am an engineering manager in a company that makes gas turbines, by night I tinker in my shed with mechanical projects. Some of my previous projects include building a blacksmiths power hammer, restoring a series 3 landy and restoring old tools. If you want to find out more you can find me on youtube under 'Machine Shop at The Bottom of the Garden'.
I have picked up an ATCO standard 16" to do up. It has been sitting in a shed for 50 odd years and so i have assumed is a non runner. I don't have a lot of experience with mowers or littel 2 stroke engines, but I am fairly experienced in taking things apart and not having too may spare bits when i put them back together!
I have a couple of questions (I am sure there will be more!!). The first is I wanted to take the crank out of its case to thoroughly clean it, but I was struggling to remove the sprocket from the crakshaft. I tried a puller and warmed it, but before I put it in the press and apply serious force I wanted to ensure that it can come off. I also wanted to know whether there was a shoulder on the sprocked component and whether this constrained the crankshaft axially. I think I may have moved it slightly and so may have to press it back on to maintain correct clearance to the crankcase bush.
The second question is whether the starting handle interface is screwed onto the clutch shaft. I have lookeds at the parts list and it looks through it is (it also has flats on it) but before I employ a long bar on it I wanted to check.
Thanks all.Look forward to making use of your experience!
