Hello,
I have an old ThermoKing OM636 that i put into my 1978 Bobcat 722 that I am going to be changing the old loop style glow plugs to the newer fast glow pencil style glow plugs and i need to know the torque specs for the glow plugs. If someone could inform me the torque specs that will be greatly appreciated.
Thank You

As it happens I have a paper factory service manual. The torque is not listed in newton meters.
This is what is in the manual.
"Apply some graphited Oil to the threads of the Glow Plug. Screw the Glow Plug into the cylinder head and tighten with 5 mkg."

You will need to find a conversion for mkg to newton meters or foot pounds.

I have never seen that measurement before but mkg a guess is it is meter kilograms. Obviously check to be sure.

Thank you, as being an german made motor I'm not surprised that the specs are in metric. An online search found that 5mkg is equal to 35.94ft-lbs. And you are right that mkg stands for meter kilograms. Thanks again.
