Glow Plugs

Yup 7/16x20 is right jerry

In order to drill I'll need to take apart to keep residue out of the engine ???

 

[Jimc]

well not really. as long as you dont go so deep that you bottom out and separate the electrode from the body. if you do that then the electrode could end up in the engine.

 

[Munchies]

If you pull injectors you can get in there and kroil it, or plug the hole into the head with a greasy/oil rag or paper towel to catch any debris if your worried.

 

[Rapracing]

At jimc. I thought the electrode was probably turning with the nut but from what you say it isn't? I was thinking the electrode would pull out leaving me the body with a hole in the middle of the body to maybe use an easy out in.

If I understand what you're saying I will actually be drilling the electrode out of the center?

 

[Jimc]

if you drill all the way to the bottom of the hole where the copper gasket would be sitting you will separate the electrode from the body. you dont want to do that. just drill in 3/4" of so. enough to get an easy out in there or something then the whole thing will come out together....hopefully.

Thanks. You didn't need to add "hopefully"

ill keep soaking a couple days and give it a try

haha, let us know what happens. remember heat is your friend!

just thought of one more question. Is the electrode hard material or will it drill easily

 

[Jimc]

i dont know what is inside those things. probably some type of ceramic encapsulated resistor wire in a metal shell.

A tip. Remove the injector and heat sink and stuff the chamber hole to the piston so drilling debris does not fall where you don't want it. That way, if electrode does separate, you can easily retrieve it and clean up with a shop vac nozzled down using tape and a piece of pvc pipe.

How many of you have heard the horrible sound of a easy out breaking???

 

[Jimc]

oh boy. did you get the broken piece out?

 

[Rapracing]

I thought I did tonight. It actually sounded and felt just like it broke but it was the glow plug breaking loose. I have attached a pic below. I changed both of them while I was doing it. Both were swollen at the end and hard to pull out of the head, especially the one that is complete. I didn't find washers on either of them and could not find them in the holes. Is it possible that there were none. If there were there are 2 in each hole now.





Thanks for all the advice and input

 

[Jimc]

it is possible there were none. thats great you got it out. i highly recommend you coat the threads in copper antisieze compound. it will make life much easier down the road

 

[storeman]

Congrats! Of course its possible there were no washers. One does what is necessary to keep thing running in the field.

[Rapracing]

Let us know how the washers work out since you will be the first to use them. The specs are right so should be fine

They seemed to work fine. I guess if there is an issue it will show up down the road but all looks good now.

Congrats on getting it out without breaking the easy out, that is usually a miserable task removing those.
