I listed out a good way to do it in the "all motor" section a few times. Just make sure you mark both just incase and zip tie the sprocket / gear to the chain upon sliding it off of the cam.
A few helpfull pointers; even though they are used I put assembly lube on the lobes and journals pre-installation. I even put lube on my 248 exh cam when I took it out and placed it in the intake side, while going from 240-248 to 248 - 232 (reasons and steps are in all motor too). Also even though it says pre-torque all journal caps in order to a set force, go in a 1/4 to 1/2 turn increments back and forth from the center out of each cam untill all the caps are seated. This will take a bit of time but it will remove almost all the risk of shattering a camshaft.. And believe it or not, it does happen and a nissan tech friend of mine has done it on a qr25
Another thing, if you push the tensioner all the way in (best to have 2 people for removal / install as it makes things much easier btw), all the oil in it will come out, of course. When you get everything back together and start her up it will make a nasty sound as it refills with oil. You can remove the fuel pump fuse and manually crank it for a few if you dont want to hear that sound
Oh and dont forget that you are doing only an initial 10in/lbs torquing and talk and keep turning and talk and keep turning till you hear a massive "click"
First bolt I put back on the first journal I busted off in the head as I spaced out for a bit, and um it took longer to fix that then the whole job plus some....
I want to crack my head open again and reverse install the 240 cam on the exhaust side giving me a non re-pinned 248-240 hehehe Then go finally for a non pined 248-248 setup so that Ill have tried every stock config other then 232-248 ( ive done a 232-232, 240-248, currently 248-232, and need / want to do 248-240, 248-248)....
Have fun
edit: if you need a picture (might be a bit dirty though
)of the cam install from the 96 fsm with specs, let me know and Ill host if for a cpl of days.
