For the NBS 6.0 sometimes the oil pump will certainly go wrong as result of a bad O-ring or one more component top top it. I just tackled this task on Saturday for my friend and we uncovered an easier way to execute it, to eliminate the oil pan you"ll have to remove the differential and also that"s simply a bunch of nonsense so I"ll provide you the measures we did.Remove the prior clip, not a requirement but it will certainly make the easier.Remove the pan shroud and also the fan itself.take every belts off including the AC belt.drain the coolant and also the oil, change the oil filter so girlfriend don"t forget however DONT refill.disconnect every radiator hoses.remove the harmonic balancer, this have the right to be a pain specifically if the puller breaks on it, we provided a socket ~ removing the bolt to push versus the crank and take the balancer off.remove the water pump.remove the plate to the timing chain and also what not, there room two bolts ~ above the bottom that this plate the go up through the oil pan, these room the only two bolts ~ above the pan that should be removed.here"s the fun part, the bolt on the bending pipe are in the pan, you can acquire a tiny wrench in there and loosen it, once this is done your going to need to use part hemoclamps (I forget what they"re actually referred to as we ended up calling castle hemoglobens and other names ns cannot short article on here) but they"re those tiny scissor looking clamp things.use this to loosen it A BIT, when its loose take a fishing wire or piece of string and also tie it approximately the bolt, if you don"t execute this and the bolt drops in the pan you"re in because that a lot more hours the work.continue acquisition it off and pull the bolt the end of the pan, as soon as its out save it on the string, you"re going to should put this back on.Now you must disassemble the oil pump itself, take it the former plate off and remove the gears, then take the 4 mounting bolts off and also you need to use a lot of finesse to acquire this off, turn it towards the top and pull, get it kitty cornered top top the gears and pull under on the flex pipe, the takes part time however you just gotta wiggle and also work with it. Don"t use a screwdriver as you don"t want to damage the oil pan gasket.now the you have the old pump turn off clean off the gaskets because that the water pump and the plate the covers the oil pump. Make certain theres no residue this is all necessary steps.take the new oil pump apart and get the ago plate on, when its rather on the equipment on the truck obtain that flex tube in there and also do the wiggle to obtain it earlier on there, the stakes are greater as you have the right to scuff up the gears do the efforts to obtain this earlier on, make certain you change the O-ring top top the flex pipe.once the flex pipeline is back on, get that flex tube up in there and also use the hemoglobens (still don"t remember the name) and also get the bolt earlier in the hole, they to speak you can shave down the bracket notch the keeps the in place however we didn"t desire a bunch of metal in his oil pan so we opted no to do this.Once that step is done put the 4 mounting bolts ~ above the new oil pump, include the gears and also put the confront plate back on.add the new plate gasket and also tighten that down, don"t end torque and blow the new gasket.replace the water pump gaskets and reinstall the water pump. Gain that harmonic balancer earlier on, you can need to hammer that on to acquire that bolt come grab the threads inside then hammer the down with the waiting gun.reinstall the belts, then the radiator hoses, add the fan earlier on and also then the shroud.
