Yanmar Injector Testing, Etc.

[LADYBUG TOO]

Is anyone aware of a Yanmar authorized test facility where injectors can be checked? Ladybug, Too's engine only had 58 hours on it when the lightning hit. We have it running with a misfire at low idle that is likely one or more injectors. Could be coil damage due to the strike. Our local Yanmar rep is not aware of a factory authorized test facility. At almost $1K per copy, I sure would like to know which, if any, are damaged. The engine interface module and display will be replaced next week and, it looks like several of the display input devices are toast. The injectors could be removed and shipped while we have the mechanic at the boat. We are having to prove to the insurance company that anything replaced is for sure dead. It makes the repair process very slow and painstakingly methodical.

Any help appreciated.

Pat,
Mack Boring is the Master service center on the northeast. They are located in NJ I'm not sure if they cover Florida. If anyone can do it it will be them. While I do not have a Ranger yet they have helped a friend on Lake Ontario with several issues with a used (non Ranger) boat. http://www.mackboring.com/

Best of luck!

I'm not sure what your meaning is when you wrote "Could be coil damage..." ! As far as I know there's no 'coil' as required for spark plugs. Diesel engines operate purely on high cylinder compression of the fuel vapor to raise its temperature to the point it self ignites. The injectors squirt fuel into the cylinders. If they get dirty or clogged in some way then the proper amount of diesel fuel injected or improper vaporization will become a problem. I'm told these Yanmar diesel engines do have the traditional cylinder glow plugs installed but simply aren't connected electrically -- so they don't operate.

I would wait for the engine ECU to get replaced to see if this resolves the issue. The ECU is the heart of the engines proper functioning.

If you have a good/new injector then one method might be to remove one injector and replace with the new one and test. Do this for each of the 4 injectors to determine which one is bad. Of course, if more than one is bad this test will not be foolproof. Also have each injector cleaned and reinstalled and then test.

For me, if my Insurance treated me in the way they're treating you I would, after having everything resolved, switch to another Ins Co.

BTW... I did contact my Yanmar service technician to ask him about an authorized test facility/method for determining proper operation of the injectors -- but have not head back from him... sorry.

Good luck.

Have you asked Marc Grove at Wefings Marine?

Coincidence, I was just at a Mack Boring class in Union NJ today and on a tour we were shown there injector pump testing facility. As far as I know they are the only ones who can do this. Call them, I am sure you can have them shipped to them. I don't have their number with me, but you can get it on line. Mike Alfano is their lead guy in NewJersey.
GOOD LUCK!!

Mike: Is the injector pump mechanical or electric driven ?

 

[knotflying]

The injector pump gets about 23,000 pounds of pressure via the common rail and is activated by the computer which is sending information to an eletronic solinoid that is part of the injector. Hope that answeres your question.

Thanks All,


The electronic solenoid is the issue for lightning damage.
