Glow Plug - installation
« on: May 26, 2016, 11:52:21 AM »

Hello all,

I just got my new glow plugs, NGK Y103V.
Looking at pictures I have from my engine,




it look like it has the some issue to pull them out of engine.
The first one is in line with the rigid line comming out of the pump.
2nd is in the manifold, and 3rd also.

Is it just an illusion, and it won't be an issue when I get to the boat ??

Please, let me know if i need special tool, or just standard metric ratchet is ok.

Thanks

Patr : It shouldn't be a problem.  Just disconnect the wire, put a wrench on it and it should clear the injector pipes coming out.

I had to pull that glow plug when I removed the injection pump for rebuild.

Take the small nuts off, remove the connecting bar.  Remove each GP one at a time.  When done reconnect the connecting bar.  Can't remember if a wrench will fit on the GP, may need a socket (deep?).

Good info/diagram! Now for the non-mechanics in the group (me), how do you know when your glow plugs need to be replaced? Is this a scheduled maintenance item after "X" number of hours, or are there some performance-based signs?

if you have an Infared thermometer activate the GP for about 15 seconds and then measure the temp of each.  They should be roughly the same.  No Thermometer use your finger, think I'd start at 5 seconds and increase until you can determine if they are working.  Unless you are having starting problems why do you think they need to be replaced?

Hi,

Thank you all for the info.

Mine is starting to take longer and longer to get a good start, and by the look, paint on them, they seams to be original 1989.
Worth the expense.....  :D

Patrice,
If your engine is original, I don't think it would be an XPB. Should be just an XP.

Hi All,

I did the glow plug change yesterday.

Boy, you need fairy fingers to do this.  Mine had knurl nut to hold the wires.  Took for ever with a long nose plyer.  Then a long socket to unscrew the glow plug just a few turn cause no more room, to finish with an open kee.

But the good news, went from 30 sec. to 8-10 sec. glowplug time to start.   Worth the job.

The XPB is a completely different engine than the M-25 or M-25XP, nothing is interchangeable. 
Unfortunately it just shares the M-25 family name -- simply for marketing.

Hi All,
 Mine had knurl nut to hold the wires.  Took for ever with a long nose plyer. 

The round, knurled nut should have had a slot in it -- that a thin flat point screwdriver will fit to turn the nut.

Yep!
I taught too...
But you get the rigid lines in the way or the air filter for the next..... even with the tiny screw driver.
Good thing it is not something you need to do once a year ...

Guys : The "dead give -away" of the XP or XPB is the color!! 
The Oshkosh XP is bronze while the Westerbeke XPB is a blueish silver!!
