#8 Plug change - ZR-1 Net Registry Forums

Hammer · 06-18-2006

I just got done changing plugs and the #8 posed a real problem at first. I made short work of it with the following special tools.
Pencil type extendable magnet (most any magnet of this type would do)
Lithium Grease
Spark plug Socket (make sure it has the rubber to hold the plug)

Removing is easy, drop you plug socket down the hole and then a short extension after that. Push it all the way in so the socket and extension are mated and are on the plug. the extension will protrude out the hole a little bit. Then connect a universal joint to the extension and a longer extension to the universal. You can screw out the plug now. Once the plug is free hold the short universal and remove the longer extension. This leaves the plug, plug socket and short extension in the hole. Pull the contraption out until you can remove the short extension. I then used the magnet to fish the socket with the plug in it out of the hole.

Installing is a little harder but it wasn't that bad either. I prepped the plug socket with lithium grease and then ran the plug in a few times to spread it over the rubber. You will see that the plug now pulls out of the socket pretty easy.

OK here goes. I used anti-seize on the plug threads by the way.
Insert the plug into the socket and lower it into the hole with the magnet, then insert the short extension into the plug socket. At this point you can just kinda twist the extension into the plug socket and tighten it by hand a little. then the universal on a long extension is inserted into the short extension and the plug tightened. Once tight you should be able to remove the plug socket from the plug. This is where the lithium grease comes in handy. Then it's just a matter of disassembling everything to the point where just the plug socket is left in the hole. retrieve it with the magnet and your done.

I hope this is clear enough that you all get the idea anyway. It worked for me and made an ugly job much easier.

here is a way thats super easy .Get a plug socket that comes witha universal [Autozone] use a3/8 breaker bar.pop that baby loose pull the bar put on a 1-1/2 ext and spin it out with your fingers. I've found also that when you first get the plug socket pull the rubber and a little round file to loosen her up and you can change all the plugs in nothing flat. just another way to do it .hope it helps.

I take the rubber out of the plug socket and use a magnet for retrieval of the plug.

Try a piece of rubber hose and stick plug in one end. Then get it down the hole and tighten. After that u just torque the plug.
