How's it going guys? I've been struggling with my motor
, a westerbeke
35b three, for a few months. Finally think I diagnosed it and had my injection pump rebuilt. Reinstalled it yesterday and went to check my timing and no fuel
out of the injector lines.
I had fuel
to the injectors before this last round of work, which included inspecting the governor and rebuilding the injector pump
The tech manual I have is a little difficult to understand at times, but as best I can read the process for checking the injector timing is to: put cyl. 1 into the start of compression
stroke, remove cyl. 1 fuel delivery
spring, energize lift
pump, hand crank motor
until the fuel stops coming from line 1. The alternative process, which I did, doesn't require the removal
of the spring, and is basically the same process, except you're looking for when the fuel starts vs when it stops.
When I pulled the lines off again, it appeared I was getting fuel through the pump, as evidenced by wet valve holders, but not through the lines themselves.
So, am I checking incorrectly? Is it possible I bent the delivery
lines somehow and fouled all three(I can blow air through all three, but it takes a bit of lung power)? Is hand cranking the motor somehow not delivering enough power to engage the injector pump
? Did I screw something up in my installation
of the fuel pump
in relation to governor(I.e. Connect my tie rod incorrectly)? I took off my v belt, which connects my crank pulley to the freshwater pump and alternator
, so as to not pump coolant
everywhere, is this somehow mucking things up? All three fuel lines are disconnected from the injectors, is there some kind of loss of pressure due to this? I'm at a loss here
After work today, I'm going to try and energize the lift
pump and hand turn the motor, check if I can see fuel coming straight from the injection pump. That's about all I've got at this point. Sorry for the long post, and appreciate any help
