Replace Jinma 204 Y385 Glow Pkugs

Pretty straight forward as long as you don’t have any problems.

Remove the buss bar and unscrew the old plug, screw in a new one and replace the buss bar.

When I did mine the #3 cylinder plug was stuck in the hole. Unscrewing it just jacked the plug apart. I got the outer housing in the socket and the electrode was stuck in the head. Barely enough of the core to get a pair of needle nose vise grips on it. Used all kinds of penetrating fluid concoctions for several days and was only able to bust it loose enough to rotate about 10 degrees back and forth. Tried heat and all the other stuck stud tricks I knew of.

Then it dawned on me that the problem was carbon buildup and a stuck copper seal. The only thing that I had on hand to attack those two things at the same time was gun barrel cleaning solution. Picked the most powerful one I had and let is soak for a couple of days and was able to work it loose.

Best advice is go easy and be patient.

Good luck

thec only thing I would suggest is when you place the new glow plugs put some never sieze on the threads. hopefully yours will come out easily. this is not a tuff repair usally.
