800 HP Marine Camshaft Swap - 14.6L Caterpillar 6NZ C-15 Diesel Engine - Peterbilt 379 EXHD

[Laughter] to do the camshafts walk on a 3406 T or C 15 caterpillar the first thing you've got to do is get the radiator charge air cooler and AC condenser out of the way the reason for that is that the camshaft won't come out of the top of the engine it has to come out of either the front or the back obviously you can't take it out of the back because the cabs in the way so it has to come out of the front I won't actually take the AC condenser off the truck I don't want to open the system up because it's working fine so I'll take it loose from the charge air cooler and fold it back up on top of the engine and then I'll pull the radiator and charge air cooler it off and then when I get that done I'll hang the AC condenser by the hoist to hold it up out of my way while I'm swapping the cams out having to pull the radiator and all this off is the worst part of the whole deal in my opinion but it's got to be done and that's what I'll start with all right so here's what this looks like so far there is the AC condenser laying up on top of the engine and there's the radiator and charge air cooler hanging from the hoist the next thing I'll do is set that down the shop floor and then I'll come back and grab a hold of this a/c condenser and hang it in here somewhere where it's out of the way as good as I can get it and then once I get that done I'm gonna come up here and pull the fan hub off as you can see it'll have to come off in order to get the peanut cover off and I'm gonna be changing this fan how about for a different one that I've got that one's missing some friction material in there I'm also going to change the crank damper out I've got a brand new Viper tech crank damper to go on this that's the old original 750 thousand mile 19 plus year old damper so the rubber inside of it is bound to be bad I'm not necessarily convinced that bad crank dampers are what break crank shafts but I'm not necessarily convinced that they aren't what break crank shafts either so I've got one this is definitely the time to put it on while it's this easy to do so I'm gonna go ahead and change my now I'll show you how to get these crank dampers apart from the pulleys there's more than one way you can do this but this is the way I normally do it it's quick and easy so you just block it up to where the pulley will go down in between the blocks and let it hang there by the damper and then you take another big square block that will go and fit in the recessed area that damper like that on top of the part of the pulley that protrudes through and then you take the bfh I'll let you figure out what that stands for and you smack this block on top and knocked the pulley out of there okay they're ready enter and charged air coolers over there on the ground AC condenser is hanging up here out of the way I've got the fan hub all and the crank damper and crank pulley off I won't put any of that back on until after I do the cam swap so I'm pretty much ready to get into the engine now the only other thing I'm going to take off is the intake so I'll take it off here where it comes out of the cab on both sides and then up here at the front get that all out of the way and when I get that done I'll be ready to pull the valve covers off and then pull the peanut cover off I think I've covered this before but these peanut cover bolts are notorious for wanting to be stuck these Torx head screws here and they're actually not a regular Torx they are Torx plus so this is a regular t 40 on the left and that's the Torx plus on the right you can kind of see the difference the Torx Plus has got wider flatter teeth and that's really what you need to have the best shot at getting these out without stripping them out what I'll do is take that bit and I'll put it in each one of those and smack the back of it with a hammer first and then I'll try to take them out I've got the intake popping off and out of the way that's the way I normally did you can just take three clamps off this way and the whole thing's going peanut covers off I got all the little Torx head bolts out without stripping any out or breaking any of them off none of them are very happy about coming out but they all finally did so I've got the engine pinned at top dead center compression number one I'm not going to get into that right now because I'm gonna make another video where I will get into that and you should see that video sometime after this one so the next thing I'm gonna do is pull the cam gear off which just consists of these six bolts right here and then that gear will come off when I get that done I'll show you what's behind the cam gear and keep moving along all right I've got the cam gear all all there is to this is the retaining ring and an adapter so the retaining ring is the part with the three bolts in it and then the adapters two-piece in the center with the DAO sticking out of it so to take this apart all you do is pull those three bolts out the ring comes off and the adapter is what times the cam shaft to the cam gear so it's just sandwiched in between the two and when you pull the retaining ring off the adapter will just slip off the cam shaft there's the retaining ring in the three bolts in this case the adapter doesn't want to come off the cam shaft or easily sometimes they will sometimes they won't so that's fine I'll just pull it all out together just leave the adapter on the cam shaft pull it out of the engine and then take the adapter off the cam shaft once I get it out it's way easier that way than trying to get it off right now okay I've got the valve covers off the Jake housings off and the rocker arms and shafts out so I am finally ready to pull the old cam shaft here here's all the top ten parts Jake housing's rocker arms rocker shafts and hardware you guys have seen all the stuff and some of my other videos if you've watched them so going up and worth going over again the old camshafts gone so from this point forward I'm putting it back together instead of taking it apart that's a good thing I'm gonna run over and get the Marine cam and bring it over here and stick it in the hole you can see what I was talking about with this adapter now I just left it on the camshaft and pulled it all out together and then gave it a few taps with a rubber hammer and it'll come right off [Music] okay once I get three journals in it's okay to let hang on it tell them there I won't let it hang with any less than green journals inside the head I've got the Marine cam in it now got the cam gear back on and to work those bolts torqued or 180 plus or minus 30 foot-pounds next thing I'll do is put the peanut cover on and then I'm all done with the front gear train reassembly is pretty much just the opposite of taking it apart so I'm not going to show a whole lot of that I am gonna make an overhead video when I run the overhead on this so that's the other video that you'll see sometime after this one but I'm anxious to get this thing going and see how it does the Marine cam match is a lot better to set a 5559 that's nothing new pretty much know exactly what they'll do and what to expect there but I know there are guys that run the Marine cam against a set of 57 injectors I've just never done it myself so I'm anxious to see exactly how well it works and pull load with it and all that so I'm gonna get this thing together I'll show you guys to start up and then we'll go for a ride this is the 10r seven one five five camshaft which is better known as the 800 marine cam it's not only a marine cam it's also used in a few SI 18s and a couple other applications too but when people are putting this cam in a regular truck engine this is the one they generally referred to as the 800 marine cam so I just figured I'd tell you that so much for leaving the AC system charged up you hear that hissing and see that big bubble in that hose right there you just started leaking I don't have it pulled in a real hard Bend or anything so it's just an old hose I think that's the original hose to the truck best aftermarket equipment you can add to a Peterbilt right there Peterbilt guys don't know what I'm talking about quick update I've got the new Viper tech crank damper on fan hub swapped out the belts are on and tie the overhead is run the engine is 100% together so the only thing I'll have to do now is get the radiator charging air cooler back on the truck get all the hoses and air intake pipes put back on a few other little things and it'll be ready to go it's all back together and ready to go I had every intention of doing a time-lapse and putting this back together but the camera operator which is me is a dumbass and you had the camera on the wrong setting so there is no time-lapse and I'm sorry about that I'll just have to try to do better next time anyway let's fire it up see if it's kind of rounder if it's gonna sling parts everywhere I'm gonna go haul some rock and I'll bring you along with me [Laughter] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music]
