53 Block

what i did was pull the air intake, turbo, exhaust manifold and down pipe off completely, i then disconnected the drive shafts and put a floor jack under the tranny, disconnected the slave cylinder from bellhousing and removed shifters for t-case and tranny from inside cab, drained anti-freeze and oil and take off the oil filter houses and electrical connections, remove intercooler lines,loosened the motor mounts( later on, youll unbolt the passenger side one completely.) after the motor mounts are loose, i jacked up on the right side of the motor only, allowing the motor to rotate slightly towards the drivers side, this allowed me access to the plugs with room to spare. put a block or a jack stand under the right side to help support the motor,. now from here, i took a 3/8 drill bit and drilled a whole into the plug, then took a long punch and pryed it out(warning: expect a little antifreeze to drain out.), used the digital diacaliper and measured it. Once youve got your measurement, replace the old plug with a new one from cummins, tap it in gently and re-install everything in reverse order that you took it off. This is a multi-day project. take you time. I took me about 2 days per truck. now with an auto, youll have to drain fluid, disconnect lines from tranny and the cooler. so it may take more time. I would NOT reccomend this to anyone who is not mechanically sound. By mechanically sound i mean being abel to do way more then just change a belt or do an oil change. Also, having a friend or two to help is adviseable.

Thanks Dukeboy I did not realize the motor would have to be laid over . Well how did you come out on your measurement ? I'm guessing it wasn't any trouble to get the MIC into the right area right below the radius where the block curves out ? Where is the 53 at on your block just curious . Did you just measure the one one between 5&6 only ?
