And the struggle continues!

Checked power and grounds to ECM, installed good batteries, and pulled transmission and removed rear timing cove and checked timing.

Hello Warren! Mr Hewes here! Not sure if you’ll see this message. But first of all thank you for the kind mention! Also I’d like to thank you again as I was watching you rebuild the transmission on a John Deere 4050. Cut a long story short. I ended up buying an abandoned 4440 of a buddy of mine after watching your videos! We are currently halfway through the rebuild, I picked up so much from your videos! Il be doing an update on it soon Il be sure to mention you! If you ever find yourself in UK swing by!

[@williamb2642]

I used to be a field service mechanic..this is exactly why i finally got out of it..too much stress trying to placate too many customers with too little appreciation of the amount of work involved in diagnose/repair of literally every year make and model of vehicle or equipment. You are a rare individual sir, and I compliment your integrity.

[@douglasmayherjr.5733]

I appreciate that you show when stuff goes wrong, like real life. You could have skipped recording this and said everything was fine. This is why I will always watch your channel and have research for what you’re doing. I wish I could help some way, but you’re the expert in this area, and I would just be guessing. Thanks Again, Warren.

[@stevesauerland223]

Updated camshaft does not use shim per parts bulletin PB00256. Early cams had damper and shim, then shim only, now cam pilot is sized so shim isn't needed.

[@bigkenny93]

This right here.

[@Slugg-O]

Damn sure looks like it. A subtle upgrade on the new cam caused this fuckery.

[@bigkenny93]

@Slugg-O yeah but like he said, the way he had the shim on the outside of the gear wasn't doing anything to effect the timing.

[@scarface-39]

But having the shim on with the updated cam, could it be causing the tone wheel to be pushed out too far? And not be affecting the actual mechanical timing?

[@markdauncey927]

No - the tone wheel bolts to the cam gear. So it stays in the same place because the idler is properly meshed.

[@LukeLong-oi4uc]

Don’t beat yourself up to much, shit happens. I use to be a independent field service mechanic. When your touching the amount of stuff that you are it’s easy to overlook something sometimes. It sometimes happens when we’re tired and being pulled so many directions. I used to have equipment pulled apart in the shop and then have to drop everything to make service calls. It was maddening!! I hung it up several years ago but kept my truck so to work on my personal equipment. Being a independent mechanic is nothing like working in a dealership or multi employee shop where you have a little more time to breathe, and other mechanics to bounce ideas off of. Keep doing what you’re doing, you’re doing fine!

[@dustinstambaugh2611]

Such a dedication to fixing correct learning and not giving up. Qualities that are very seldom found in a heavy duty mechanics not to mention the added frustration of videoing. Everyone could learn from you Warren

[@elrobo3568]

I have run into many of the same problems with "who the hell designed this?" with the jet aircraft I worked on for years. I had to work with the "engineers" that designed the F-16 and when I asked them if they ever talked to mechanics that fixed these jets and they said no. No wonder.

[@user-xn4pv9gk5s]

Hi Warren, Former Peterbilt DTM here. The nose of the camshaft has been changed on the service parts to be thicker and no longer required a tolerance washer. Measure from the retaining groove to the cam nose mounting flange. Washer likely not needed on this cam.

[@markbrandon7756]

Curious when and where this is in the manuals or is it in parts notes when part is sold ?

[@markbrandon7756]

I thought this was it but as I finished the video he is back at the vgt…. But the cam update is still curious how and if the service bulletin or other covered it.

[@richardlincoln8438]

​@@markbrandon7756 According to another commenter there is a part bulletin for the updated cam #PB00256. Would You imagine the corkstuffers at Paccar include that information with such a expensive and critical engine part ?

[@Sentry682010]

Watching from Australia. The anticipation waiting for the next episode is better than most TV dramas! Great methodology, knowledge, but also humility and humour. Reminds me of when I replaced half the components on my 70’s Holden and spent weeks chasing a problem that had it stalling every time I turned left - turned our to be a faulty brand-new ignition coil - horizontally mounted, it obviously had insufficient insulating oil in it, and turning left was exposing windings internally and allowing the HV side of the coil to arc to ground. Put the old coil back on - solved!

[@daltoncarr8861]

I would love the opportunity to shake your hand one day. We’ve all been in these situations where you just hate to have to figure out what’s wrong. You don’t know if it’s your fault or something else. Just weighs so heavy on you. Makes me wonder sometimes if a 72 hour hold at the hospital would be worth a vacation. I feel it’s in these moments we find out what kind of man we are and I just hope I’m able to stick it out like you are. The amount of perseverance shown is bewildering. Keep being you.

[@CrimeVid]

Keep going Warren ! when you have it down to individual parts you can build it properly ! You have a ridiculous amount of patience mate. I too like Mr Hewes, also Marty T who will have a go at anything as far as I can see ! just watched him fixing an electric hub drive he’s putting in an ATV. I think your problem is going to prove to be Electrical, I’m sure that one switch is not letting another switch operate for some reason that only an Italian engineer would understand. You did not waste today’s work, you made sure of a thing and fixed a mistake, has to be good. Again,good luck mate.

[@user-jn6cp8fn8b]

Someone else mentioned that the spacer is not used with the updated cam. When you had it behind the cam gear it moved the tone wheel back out of alignment with the cam sensor resulting in erratic cam signal confusing the ECM. While the tone wheel doesn't mount with the bolt holes the spacer does and the space makes no difference when in the front, it does make a difference when behind the cam gear.

[@trevormitson6026]

If I'm following you correctly...Warren, fitted the spacer behind the cam gear, (transmission side) not between the cam, and cam gear, and shew that it didn't actually affect the tone wheel in any way ..

[@macbeth2354]

Looked like the tone wheel still mounts to the cam gear face, fitting through the spacer (minute 12:30 or so disassembly). But I'm getting your point about the different measurements on the old vs updated cam.

[@user-jn6cp8fn8b]

@@macbeth2354 I think partial reassembly and then removing the cam sensor and looking in / sticking an inspection camera in to check the alignment is needed. It seems almost certain now that the tone wheel is not getting properly aligned with the sensor. Whether it's due to the current spacer, or possibly needing a different spacer or tone wheel to match the new cam.

Rest assured Mr Hewes knows who you are, Warren. A bunch of us recommended your channel when Joe was trying to fix a John Deere power shift tractor. Those guys are a riot. Make sure you watch the video where they drag the Cat excavator home.

[@ryanjohnson4320]

Warren, One thing to do, is unplug all the injectors and check the resistance of each coil. One could be shorted and pull the drivers down inside the ECM. I had an engine do this one time and caused erratic injection timing, and ultimately a no start. Had no codes as well. Was a Cummins engine though. Crank no start with no codes and no smoke. Once I found the shorted injector coil, I left that one unplugged, and the engine fired up. When you have cam or crank unplugged, it wont fire injectors, so you'll get normal cadence cranking. I feel your frustration, I really do. Shop owner myself.

[@obiecanobie919]

Yes try disconnecting three injectors at a time , see what happens

[@timmieclark9976]

It's always good to start at the beginning and verify, especially if you were second guessing yourself.

[@themalewhale59]

It is always so simple once you find it. Finding it is rarely simple.

[@NationRazor123]

We’ve had one in the shop before where we had the same situation checked timing again like you did, turned out both new unit pumps were bad and once replaced it fired up.

[@norb0254]

I would say the pump units are ok as there is excessive rail pressure ,the injectors are blocked and not firing due to dirt /debris

[@joeboss1750]

Hi there Warren. It almost looks like the new cam has been beefed up, so as to do away, with the spacer washer, in which case, fitting the washer could, space away the tone ring, from the sensor. Thing is, it ran initially, I think you said in an earlier vid, so the EGR valve is looking more of a possible answer. Good videos though, and fair play to you for posting. Most people only show their successes, and WE ALL, fu.k up, as WE ALL know !!

[@deweydecimal1446]

Measure from where the mating side of the timing cover (where it meets the back of the block) to the center of the cam sensor head mounted in the timing cover. Then you will know where you need to locate the tone ring, as far as spacing.

[@onemessedupfarmer]

I was thinking the same just to know for sure that the tone wheel is running close enough to the sensor.

You hit the nail on the head @3:40. I am an engineer for a large equipment OEM and im in my 40s. I am one of the few that works on equipment in my spare time and grew up doing it. Most do not. And the younger group coming in rarely have any hands on experience with equipment or working on things. It doesn't look like it will get any better. And us older experienced engineers can''t catch all the serviceability issues and even if we do, we get overuled by managers who say thats a nice to have. Bigger flywheel housing costs more money so some manager with no hands on equipment experience probably nixed that because of extra cost!!!
