- Welcome back to another video of working on the truck! Today we're still trying to track down that stupid little shake(s) I've been getting, and next up being loaded into the parts cannon is the external wiring harness. Let's see if this sticks! (Probably Not)
2006 Peterbilt 379
CAT C15 MXS 650hp
Every truck I drove in 45years. One of the first thing I always did was change the fuel lines. That and put a fuel pressure gauge in the dash. Just Saying. Good Luck. Stay Safe. 🇺🇸😎
The crank could possibly be professionally balanced at both ends. Clutch side and front of engine but you would need to ask around about getting that done. The vibration issue eventually translates into a broken crank or any other number of other expensive issues. The two more recent videos at Delray JYD regarding the rebuild of a 359 EXHD has a sharp craftsman named Chris building a wiring harness and he does impressive work. He will custom build a wiring harness for less than the cost of manufacturer and specific to need. Interesting video.
From JPayDirt channel .... Came across this excellent primer on these critical engine components. JPayDirt a couple of years back maybe 2018 actually took one off his truck and cut it in half to reveal a congealed hardened mass of silicone. The damper is replaced at 500,000 miles typically. This 10 minute video will be helpful in understanding why they need to be changed. The balancer is like the Centramatic unit for truck wheels but is filled with mercury rather than beads.
Jay here's some vip info pass it on i no longer buy injectors....Deformed injector seats cat knows about this factor defect on these older heads I fixed mine no more shake,miss,overheat worked great after I pulled injectors and remachined the seats.heres the tool kit #c15-3055
I think its a good feeling to step back and look at your work and pat yourself on the back!!!. Lets have a contest: Name this truck!!! Be cool!
You guys can name her whatever you want, she already has a name though it just still a surprise!
@@callthemall Ok. I guess I have exhausted my name requests so I'll wait . But I would bet the name has something to do with music !!!
This could be a good start, like we said before parts changing is expensive, but hopefully it will solve the problem. Heat and time could crack wires where you can't find it. Hopefully this is it, if not we will still be here to support you. Stay safe out there my friend and keep the videos coming and always travel safely catch you on the next one.
U got a design on ur sleeper, I like it. Love the truck in general, keep it up
Absolutely love this guy, funny in his own way. You have good humor
HAPPY FATHER'S DAY to you & your Dad.
Ding the right thing eliminating one thing at a time, it can be a pain to find a miss or shake at any rpm range.
It’s expensive but necessary! And should be much farther ahead after it’s all done!
Watch adept apes latest video he posted, he called it shaky
I was just going to recommend that. Josh just did a video about a shake. 👍
@@kimberlynuttall3972 Yeah, imagine the timing on that one!!
So if you don't want it to burn down separate those cables to the alternator, one is hot and the other is a ground, put them in there own respective looms or you will have a fire one day
Good plan thanks man!
proper preparation prevents piss poor performance. lol we use to say that when we were dirt track racing. ❤ from pnw oregon
Well, you might as well try to change out what you can before winter. Because you know when water and salt get in to everything, Things start breaking down. You should see the custom PC wire management. This is the same thing.keeping everything clean from touching.
Check your harmonic balancer could even believe or not a broken or out of balance crankshaft and cat heads have a defect from the start where injector seats are crooked look up on-site mobile repair cat injector seats..also pull valve covers inspect cam lobes for flaking chipping anything out of normal 🇨🇦 🍁 🇨🇦
Next time u roll through Wisconsin keep an eye out for a 2006 379 blue daycab with straight pipe u will know who it is bc it’s all decked out just lay down the horn and flip me off I’ll roll down my window and say heyyyyy buddy 😆
Yeahhh buddy!!
I changed that harness on my 6nz a few years ago and mixed up the oil pressure and elevation sensor. I cooked a piston on the first big hill. I thought the connectors were idiot proof. I was wrong.
😲
Ochhh
can you make a video about being an owner op right now with prices maybe breakdown finances if it's okay with you?
Hey bud. Your shake is fuel delivery related. Have your fuel pressure tested
I have a gauge semi-permanently mounted on my mirror bracket now, and it stays within spec but occasionally drops like it’s sneaking air into the system. Inconsistent with the shaking though, but I do agree it is with fuel delivery, whether the lines, pump, or injectors themselves.
Injector seats cause this..
Does your oil dipstick ever show signs of back pressure?
translated by Mr. Google: It will not be the engine mounts? I like the 5000 meter! that doesn't fail.
Why is your check engine light on? Might want to check that.
Good grief! What year is that CRX?
86, first gen and he’s had it since new!
@@callthemall He's done a great job keeping it up.
@@excavatoree OH yeah, 300'000(ish) kms of beating on and racing, on it's 3rd or 4th engine rebuild lol
Where can I Oder a harness for a 1994 Peterbilt please help
dads a badass lol
What did you ever find out? After doing both harnesses and injectors? What was the problem? I’m having the same exact issue but mines injectors 1&2 high low voltage………
I believe it ended up being some bum injectors. You might have ecm issue if it’s throwing codes. You can see if there’s another ecm around that you can swap and see
Was it 650 HP from the start or is it chiptuned? How much torque? 3000 Nm/2,205.88 lbf?
Your video's rock.. Like plugging a Les paul into a marshall JCM800 and all the levels are at 10. Just a thought could the shaking be a damper of fuel pump? Do you ever go to Madoc?
Likely not the dampener, and Fuel pressure stays consistent though I’m not 100% ruling out the pump. I may still be getting air in the fuel system somewhere. And yeah I’ve been to madoc quite a bit picking up stone
Some might not agree, but have you tried some Marvel Mystery Oil?
Nice bro 👏👏👏👍
Have you tried looking at it with one of those heat gun thermometers? That would at least narrow down which cylinder it is?
Yeah but couldn’t find anything really conclusive
Have you changed out the primer pump? I have had them suck air before and I finally deleted it on my E model. Cat makes a block off plate for it and I just carry around a primer pump to get me out of a jam.
Yep changed the primer pump pretty early on. It was pushing out fuel past the rings, which means air is coming in in its place! No change ultimately though
Did you ever replace the crankshaft damper. Fluid Damper is made in the USA 🇺🇸
Balancer was replaced when engine was rebuilt, but it was removed and reinstalled when the front timing cover gasket was changed, and that’s when the original shake at speed started happening..
@@callthemall I think your problem is going to be in that vicinity then. It is certainly worth checking out.
@@callthemallok so he may have put the damper on backwards
Ok I have to ask Matt. If you had the opportunity to change out that motor all together would you ? And would you keep it a CAT or change it for something else?
I would imagine it would be cheaper to chase down whatever shake I’m dealing with right now than replacing the engine! And I would stick with CAT, maybe an earlier model though if emissions laws would allow that
@@callthemall oh most definitely be cheaper haha that’s why I said if you could. Like someone following you on your TH-cam channel offered you one. Well hopefully you figure it out anyways.
You are curious as a cat 🐈
