This is embarrassing to post as it highlights my own stupidity.
I have a ford Lehman
120 hp and a Westerbeke
15KW BTDC genset.
To change the oil
I use a sump pump and select either gen or eng, for what ever reason I mixed them up, I thought I was changing the engine oil
yet was actually changing the gen set.
Yes all the signs were there, not much oil came out and I thought 'wow that was not much', the engine
dip stick wasn't moving, 'don't remember it this slow before' all the time I was convinced that I was changing the engine while I was actually changing the gen set.
So what happened, well after I shoved 15 liters of oil into the Westerbeke
which should take 6 liters, I started the gen set to heat the 'old oil' to change that.
It started perfectly, but then there was a metallic clicking noise
straight away that caused me to stop the generator
as it didn't sound right, it ran for maybe 2-3 secs before I hit the stop button.
Minutes passed as I looked at the generator
to see what had caused the noise
, I noted oil coming out of the oil dipstick hole (still didnt click what I had done). I hit the start button again and nothing.
Only then did I realize that I had been filling the gen and not the engine.
You can imagine the language!
So what damage have I done? Local mechanic
came down and tried to turn the crankshaft, which he couldn't as with 3 belts and two alternators, removed these yet still couldn't get the double belt pulley off the crankshaft in order to get to the crankshaft nut to put some leverage and see if the engine turns.
Subsequently I have put pressure on the double pulley just by hand and have been able to turn the crankshaft a full revolution, not easy, yet that tells me that maybe the inside is OK.
So what was the noise and why doesn't the engine crank.
Go to the starter motor
, plenty of battery
power, yet nothing when the start button in hit.
I'm now thinking that maybe I have buggered that somehow, and that this was the cause of the metallic clicking sound.
Too much pressure on the starter initially with the engine overfilled with oil
and it failed?
Or just a huge coincidence that the starter motor
would have failed anyway and the oil issue was just a distraction?
Pull the starter out is the obvious thing to do, yet there is next to no access and I would probably need to pull the gen set out or just move it in the boat to do so.
I could get a new starter motor, go to all that effort, put it in and have the same thing happen again! as the engine really is stuffed.
I doubt anyone has ever done the same before, but it would be great to know for sure if the engine is toast or not.
