    Default Eberspacher D4 glow plug tool

    I need to remove the glow plug and screen from a D4 Eber-doesn't-splutter and don't have the special tool. It looks from a pic of it as though it's just a box spanner with a slot cut up the side to clear the wire. Can anyone tell me the spanner and slot size please so I can make one before going to the boat?

    Alternatively has anyone in Brighton/Lewes got one to lend/sell please? (Local agent not very helpful.)

    Thanks!

    If you buy a new glow pin then you will (or should) receive the special slotted socket with it. From memory it is 12mm - but don't cut a groove out of a basic box spanner (like you'd get for an outboard spark plug because it weakens it too much.

    If you search my previous posts you should find one with a picture of the long socket that I ground a slot in. It looks similar to the one supplied with a new glow pin.

    Here is the previous thread with pictures of the modified deep socket (next to the one that came with the new plug!).

    Thank you. According to our local agent you no longer get a free spanner with the 70 plug. The spanner is about 7 extra. In any case the first objective is to get the screen out to clean it. (I will check the plug resistance/continuity.)

    I was going to use a long tubular pressed steel one like the pic you've posted of the Eber one. I guess what you saying is that a short one slotted all the way up won't work? If it really needs a good quality long socket like the one you modified then the bloke it's for can buy one, i'm not destroying my set of them!

    I found that a standard 12mm socket with a slot cut in it was fine too. Tight on clearance but OK. (I'd ordered a deep one but it didn't show up in time).

    P.S. my tip for extracting the screen is to put a turn of insulating tape around the tip of the insertion tool to make it a tight fit inside the screen. Push it in with a turning motion, keep rotating and screw the old screen back out in one piece.
