002/003 Glow Plugs

[Light in the Dark]

Exactly how difficult is the removal on these things? I don't know if mine are working or not, but I have multiple sets of each for my 002, and was considering just putting new ones in because I can.

Wicked cold snap is due tonight (-20 with wind chill and 60mph gusts).. so doubtful its anything I would want to tackle after work... but as winter is finally starting to set in properly, I would be fool to not look into this now. Another 6 inches of snow with ice and rain are due over the weekend. Got me thinking

Any special tools required? Probably addressed in a TM, but I am at work and the topic crossed my mind.

There should be some good threads on this topic, and yeah it's covered nicely in the TMs.

Take the wire off each glow plug. Use a VOM (volt / ohm meter) and measure the resistance from the terminal to each glow plug to ground. If you get 5 ohms, the glow plug is good. If you get a higher resistance, the glow plug is bad.

Use a small torch to heat the area around the threads before you start. That will expand the metal to make it easier for the glow plugs to come out. Just be patient because you don't want one breaking off in the head.

I would also treat each glow plug with PB Blaster a few days beforehand.

That is just about the best advice given here ! They can get really rusted in ! I also put "anti-seize" on the threads before reinstalling the new ones.

I just replaced #1 & 2 while I was doing yearly service on my 003a.
The very front one I had to work back and forth ( in/out ) with the ratchet as it was binding but it came out, #2 came right out. I will get back to #3 & 4 later as they seem to be a little more difficult to get at and I was running out of time. I did have to modify a oil seal tool/pick on my grinder to get out one of the copper washers.
