The world would be so much better off with people like Warren in it, people who take pride in their work and do the right thing for their customers. Good job Warren.

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

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.

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.

Come on guys let's all give Warren a like ..for his hard work and dedication 👏

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.

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.

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!

Those paccars are good on fuel just so u can donate the proceeds to your local mechanic lol

If you had to work on that Paccar the rest of your life I sure would like to know what the hell you did in a previous life to deserve it ?

Hello Warren! Mr Hewes here!

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.

Warren this is tough on you but it's U tube gold because seeing you deal with the diagnosis of a difficult problem increaese our understanding of how these engines work. Thanks for taking the trouble.

Your ability to keep your calm, on youtube or in general, is damn amazing. I sure wish I lived closer to you, to help out.. I feel your knee pain everytime you gotta crawl out from under that truck to get a tool, etc. Kudo's to you for your determination.

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!

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.

I’m on the edge of my seat waiting for the next update.. thanks Warren for all the education….

Keep going Warren ! when you have it down to individual parts you can build it properly ! You have a ridiculous amount of patience mate.

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.

There is no doubt the mechanical genius will get this right.
