Bleeding Yanmar 230/240
Posted: Sep 4th, '15, 16:24
So, ran one engine dry. Long story, basically fuel theft discovered when the engine died. Literally, ran completely out of fuel.
Refiled fuel tank, got fuel to primary filter (good filter, not replaced), and changed secondary filter on engine. Poured fuel into secondary filter all the way to the top. Pumped that horrible little hand pump mounted on the engine, and it seems to be supplying fuel at least to the secondary filter. That little pump suxs, by the way. I think it moves a .05 of the teaspoon per pump.
Crank, crank, crank. Best results were a slow, almost combustion, but never really fires.
Manual that came with engine is zero help. It suggests that if you have fuel to the top of the secondary filter, thing should start by just cranking. But, it that 10 attempts or 100? I did about 10.
Proposed plan:
1. Crack fuel feed from secondary to injector pump, and hand pump 100 times til steady fuel comes out inlet to injection pump.
2. Crack fuel line at injector and crank engine til steady fuel comes out. Repeat at each injector.
Is that a workable plan?
Thanks in advance.
