support the underside of the boss with something like a steel block or mash hammer
HI Norm,
Thanks for the suggestion, I'll try using a sledge on one side and a hammer on the other and see how we go.
So, while curious to see what damage may have been done (If any), I removed the pull start. I found that when the piston gets right towards the top, there is quite a bit of resistance. I haven't disassembled the engine further than that at this point, but my next port of call would be removing the head. my initial thoughts are still that the conrod may have been bent, or, it could be that something is misaligned, like a ring issue. When I pull off the head and exhaust, hopefully tomorrow, I'll know more.
So the person I purchased the mower off has obviously done a bit of work on it. The body of the engine has fins consistent with the VE series, and the MSV562 is supposed to have the VEX60. Curious, the crank pin in place is the older style (4 notches). Further to this, the boss that's supposed to be on this model is
EN73162B. The issue is that the boss that's on there looks different, and I feel would be quite difficult to remove. If you look at the aforementioned boss, you'll note that between the pulley and end of the boss, the shaft is tapered but straight. The boss installed on my crankshaft has a bit of a cup between the pully and shaft. So there's maybe an inch to hammer on, and about another inch that's rounded and I don't know that I can really hammer on that.
I'll let you know how I go in the morning.
Cheers,
