Rebuilding A Kenworth W900 550 HP Cummins ISX Day #4 did we Set the Head? 

Alison has patient, to put together two motors and dealing with you all at the same time, incredible.

That Allison is amazing. She must have had a very good teacher. That motor should work hard and last for years. Great job Allison.

Gee, at the end of this we'll all be trainee Diesel Mechanics, lol. Great Series on the Motor. Great Family there. Hats off to Alison for her Knowledge, Well done girl !

Allison She's worth a million dollars. She definitely knows her stuff. Mad Respect to you.

What a great job!! Absolutely love Allison!! The Cummins whisperer 🙂

Allison is amazing, she sure knows her stuff, I hope she knows her worth...very interesting videos, get done and get home to TDUBS, miss her in the videos...Rick from Kutztown Pa

OK, here I am an old retired master mechanic watching you and Allison do this work. I have seen or done this many times and I have to tell you Allson is the best mechanic / instructor I have ever watched. Allison, when you are done wrenching you would be an excellent instructor at any school. I admire your technical knowledge and attention to detail. Thank you both for these videos!

I love the channel but watching this rebuild has been an amazing experience. It's crazy for such a big machine that makes such power where every part is way heavy requires the skills of a watchmaker to assemble ! You are so lucky to be helped by a first class team. I am so looking forward to the first start up, well I guess Justin is more excited to make that happen than I am. :)

Shiny, shiny, looks like it’s coming along great. Soon to be back on the road woo hoo Go Allison she’s a boss 😎💫 haha 😂 poor Andrew, so much flack haha 😂

Wow what an amazing job Justin together with Haggai family and Allison man I don't have words to describe how awesome she is. I don't want to have to rebuild mine yet but looking at you and Allison almost makes me want to do it. 😁 All I know for sure is that when that time comes I am heading straight to Haggai. Thank you for another great video and letting us follow along and learn a few things along the way.

Always a fun time down at the shop! Hope the new power-plant is a 1,000,000+ miler!

Fantastic, a great team getting it done. Thanks Justin and Allison for bring the trucker nation along. Stay Alert, Arrive Alive

Justin Alison is amazing 🤩!!!! So great to see your truck on its way back to life!!!! Thanks for taking us along on this awesome journey with you!!! HAGGAI is an amazing shop it’s great to see the daily stuff that goes on in the shop!!! It’s okay if you can’t get it all on video we know the truck is more important!!! See you tomorrow!!!!

It was good to meet you today. I completely understand about the time and just the distraction. Looks like you may make it home before the week is over. I'm sure your boys are ready. T-dubs as well of course.

When I still worked turning wrenches we were told not to touch the bearing surface with our fingers. The theory was that the oil on your hands was a detergent oil and it could cause premature failure of the bearing or pitting.

As a retired engineer I have the greatest respect for the level of knowledge and skill that Allison possesses. You can always tell how much an engineer knows their stuff by how routinely they talk about something as though it was common knowledge. Allison obviously had a very good teacher and was a very good learner. Respect to you Allison.

Kudos to Allison is amazing how she explained all difficult mechanics with great clarity. She knows and loves this trade, transpired all confidence.

Just trucking I’m really enjoying this rebuild series.

I had the opportunity to meet Allison you are so fortunate to avail yourself of her tremendous experience .

"Allison is a rock star." Mic drop.

Alison is a boss

She need her own channel

Pretty cool. She knows her stuff. 🇺🇸

Allison is a rock star!

Beautiful.. the truck is going to be worth a good chunk of money after this rebuild.. I know he ain’t selling it, but should be Uber reliable for many years to come and serve his family well!

Justin, this has been a great week watching you and Allison rebuild your motor. She is a great mechanic !! You couldn’t ask for any better. She’s a Master Chef in the diesel world. Much respect to her and the Haggai family! Now to get it back on the road. Can’t wait to hear you fire it up!!!

So do you think you will still be there Monday? If you are, I'm bringing lunch for the crew.

Allison is AWSOME great young lady with brains and solid work ethic...

Did somebody measure the crank shaft or did they just put the same size bearing back in? I would have thought they would have put the rod bearings in before installing the piston. Really enjoying this rebuild. What a great opportunity to work with somebody that has the experience and know how. Allison knows her stuff, great job.

Awesome to see it coming together great people truly appreciate you sharing can’t wait to hear them parts running

Justin add a line on the outside of your socket when torquing the mains makes it even easier to see your final 180.

It’s so cool watching this . I am learning a lot on how much work it takes to do this.👍

Boy I like to work for Allison's place girl is. outstanding with her work ethic.she could really teach me alot God bless her

Watching this has really been neat. Great watching small shop with people as knowledgeable that they are.

I love watching these videos. You all are doing an amazing job and thank you so much for sharing.

Looks good so far, but I do have to say you gave me a heart attack when you hit the main bearing bolts with the impact gun to go 180° past tourq, instead of using a breaker bar

Good video! Only thing i do different when rolling bearings in is i use a brass rod or a brass punch. keep up the good work.

Great video!! Love the channel!!! Glad to see the rebuild is coming along!!!

Coming along good! Enjoying these videos, been helping me get through the work week 👍🏼

I'm like you, it's fun when you get involved in fixing your equipment. When you get the time, you really need to interview Allison. I bet her story, is extremely interesting. Great vid Justin. Good luck finishing it up!

i love the fact that you upload pretty much every time i go on my 10 hour, always fun to watch you after a long day

Nice videos of this rebuild process! It's nice knowing that you had a part in it and understand what it takes to do one of these! Having a great person like Allison really helps!

Your in-depth hands on with EVERY thing you do is a perfect teaching tool for today’s youth!! Keep it up we ALL can learn from you and apply it !

Well done Justin,with the assembly of your new engine. Well almost new. And thank-you for sharing it with us. I pray that all continues to go as planned, with getting it all together. God Bless you and your beautiful family. John Queensland Australia.

Hey Justin...love the channel. Watching this rebuild has been amazing.. Thank you for bringing us along !!!!

Man I'm loving this rebuild series! I'm about to make the jump to get my own rig and this is great info! Keep up the good work brother!

Really enjoying this rebuild and looking forward to day 5. I love your content. From Zambia.

It’s hard to find videos about trucking that ain’t negative u are a humble guy an I enjoy ur videos I just got into trucking it has been a passion for 17 yrs finally found someone willing to let me rip an tear in there truck now Im hauling over size loads throughout pa nj md

And vary informative with dropping pistons you make great content. Thank you.

You are blessed to have friends like Allison and the rest of the guys at the shop! I was hoping you would be finished by Friday afternoon so you could be back home with your family for the weekend. It is going to be close. Not many truck drivers can say they assisted in the rebuilding of their engine. Assisted is probably not the right word, as you did a lot more than just assisting. But Allison was the surgeon and teacher. I have watched the progress of the build every night, it has been better than watching TV! I know you will feel more confident driving the rig down the road after the rebuild. I hope someone will discuss the break-in procedure for the rebuild. Hopefully you will be back on the road next week making some money.

Thanks for sharing this build. Very cool bunch of people in that shop they no there stuff. Great job Allison you sure no your stuff.

I'm a new driver and this is just so interesting. Thank you for showing everything and explaining what each part does.

Slow and steady wins the race. The engine is coming along nicely.

You know it is a great bunch of people and shop when they have a lot of work to do and still take the time to help others and teach those that want to learn.

I’m learning a lot by watching this thank you for showing us this

Fantastic engine rebuilding … I find something interesting other than regular gas engine rebuilding … keep up the good work , Allison

Facinating insight Justin . This is a first. Thanks for sharing.

I love that they let you show everything and also love seeing younger people with a trade skill like this. Allison seems to be one hell of a diesel mechanic.

Great Job Allison. Got a 5 yrs old Allison here in Las Vegas love taking thing apart and putting back together. You Ladies are smart and Good at what you do. Keep up the Great Work you Do.

Great series, waiting for the final rebuilt motor, great jobs for Allison!

Damn, great video. Thank you for sharing the process of having your rebuild down. I think Haagai has earned my business for sure.

I have been around trucks over 25 years, see someone like Alison doing this rebuild is impressive.

nice work bro, amazing rebuild, for me the best job

This was awesome!! As a driver it was an honor to see an engine being rebuilt!! 👍🏽🇬🇺🤙🏽

That's crazy to think of how expensive all the parts are, and the precision needed to assemble and get everything just right and use a $5.00 rubber mallet to tap the heads down. This has been fun to watch and can't wait to hear this engine come to life .

That’s a super job that Allison and y’all are doing. That engine will be a good strong engine for a long time. I’m really enjoying watching you guys do this. 👍👍👍❤️

Good bless you brother. I'm glad your getting her back together so you can get back home to the family and back to making that money

That is awesome that they let you help a lot of shops won't let you past the door.

Thanks for sharing this journey with us King!! I appreciate it.

Allison has a really lovely demeanor. Just ideal for being a great teacher. Well done guys

Justin you such a lucky guy to have this family next to you!! I’m really enjoying this videos!!

Great video rebuilt Kenworth cummins engines. Again. 🚚

Alison: You are amazing! Leading the way in truck rebuilds. The Hey Guy aka Haggai is going to have trucks lined up from Griffin Ga to Greensboro for repairs. This is a top notch shop.

Muy chingon! All I want is come home after work and see your videos of engine rebuild!

it was good seeing the w9 and you again today justin i have some things to do tomorrow morning early but i am going to try and swing by there again and hopefully i can see the pretty tdubs if i get lucky

I think your engine is in good hands. Allison is amazing. Hope it’s up and running soon.

Exciting for you. You’re a hard worker my friend. Build is lookin good.

Glad she's coming together. 🙏

Love the motor rebuild, but we need you back on the road! Thank you to Allison and Haggai for walking us through the process.

Awesome job, "gettin it done" 👏🏼👏🏼👏🏼

Just trucking l’m really enjoying this rebuilding series.

I like how you clean everything looks good Allison is unbelievable she is very smart

Allison is a rock star! Great job!

Allison, you rock… thank you for all you do

Alison is amazingly patient, juggling 2 engines and you Justine ,i think you’re the hard part justin 🤣

Dang man there getting it done fast, I'm scheduled to come in there the 16th this month to look over my "tune" that another shop botched, I'm excited to meet the crew

Indeed Allison is probably one of the most intelligent person I have ever seen. She is totally amazing.

Great video loving every minute of it!

Nice I’ve done hundreds of these in Australia and I did the first campaigns on the signatures I was also the first to rebuild and dyno a signature at more than 620 hp

SUCH A PLEASURE MEETING YOU, BRO. BLESS YOU!!

Great video. I’m so excited can’t wait to hear it run!!!!!!!!!👍👍👍👍

I use to be a heavy equipment mechanic and Allison is a great mechanic. Her knowledge is amazing. She is a asset to that shop

Allison is awesome! Very knowledgeable. Still think ya need to put headers and a blower on it. :o) Great job by the whole team! Cheers from Texas!

Wow great education amazing brother keep up the good work....

What a great series. I'm really loving it!

I'll echo what many others have said. Allison is a pleasure to watch. I truly enjoy seeing women working in fields like this. Her knowledge skill and attention to detail is phenomenal. When she speaks her passion for the field is evident by her concise and detailed knowledge. Its deceptive because she looks so young. She clearly has the soul of an old Diesel mechanic.

can't wait to hear how it runs. good video content. keep it up brother

Awesome Vidya I don't know why but there is something about a Lady Mechanic that just does it for me. I really enjoy listening to the knowledge that Ms Allison has. She should start her own RU-vid channel.

Awsome video again! Blessed dude! Hard work!! Pays off!!

Makes me want a t600 with a Cummins so much more now. Gosh I am pumped to get my own truck
