So I just got done rebuilding our generator engine
after hydrolocking it. Replaced just about everything but the crank shaft and connecting rods. New head
, new pistons and sleeves, new seal on everything etc.
On thing that did stay was the fuel pump
Which is what's confusing me now. It's running at 1800 rpm
which is what the generator
calls for. It's putting out the right voltage at 60.4hz with about a 10% load. But it sounds a lot slower than it used to, and the throttle lever itself is maybe a third as advanced as it used to be.
Is there some reason it might have been at far higher rpm
originally? It really seems to be running a lot slower than it used to, but I'm reading the rpm straight from the crank shaft, and the voltage/freq looks correct. I might be imagining it too, but it also seems to be making more 'diesel rattling' noise
The throttle thing just has me looking at it sideways. Should it be so much lower throttle to achieve the same rpm after a rebuild
? It's a really new generator, 450 hours, the original setting was from the OEM that put the unit together. I'm a bit scared to put a full load on it in case I've done something stupid.
