IN UNDER 1 HR! Bosch P7100 Rebuild 4 MINT 5.9L 1995 Dodge Ram x

[@pthomson9736]

"Here's your problem lady". I love it. Wes' favorite line.

[@mejesse809]

He stole that from SMA

[@somedudeRyan]

In 20 years there won't be anyone competent enough to replicate this kind of work.

[@nealc.6927]

I hope you guys have had someone apprenticed to this man, cos he's damn near irreplaceable!

[@Blain5700]

It was a joy to watch this man work. Truly someone who knows his craft. If I ever need one rebuilt, I know where it's going.

[@reynoldscs]

It sure was! As a technician myself, this is what I call ART.

[@gs1100ed]

ADS is the place to go

[@mikenonameneeded3485]

I feel very confident that I could disassemble that entire pump completely. Putting it back together is a whole different story. Lol

[@jeffo881]

another field trip from WWW to ADS, yeah. love this content keep it up.

[@colingraham1065]

Like watching a time served concert pianist playing squeezing everything out of an instrument. Excellent!

[@billholemo2518]

You guys get much praise from Wes. As a 40 yr. diesel mechanic, I am excited to watch you guys. All my past experience was cumming, Mack ,cat, Duetz, Mercedes. Owners never Believed, that pump has more going on inside than their engine. Lol.. keep up the good work!!

[@smulderphotography2145]

There’s nothing like watching somebody who is at the top of their craft! Awesome vid 🙌🏻

[@GusFromDaysPast]

Love it at the end. "There's your problem lady." 🤣

[@stephencooney9870]

In my time I was a plant site technician in the UK, and the Bosch "P" series pump was common place, hence I found myself with Bosch technicians a fare bit. Most where average to good, but sometimes you found yourself with a real clever guy that knew the product and was worth his salt. I am in no doubt that Gary is equal to the high level Top guns of my days back in late 1994 onwards. The sound of the test bench and the smell of the calibration fluid came rushing back. Really enjoyed this video and hope to see more. When Wes started the truck after rebuild it was clearly fixed.

[@willbgrill]

It's one thing to watch someone on KZbin build high HP performance engine with an aftermarket block, crank, cam, rods, pistons, etc... but watching a someone whose had a career in fixing, rebuilding and calibrating injection pumps is mesmerizing. I almost forgot about Wes's "unicorns are real" video until this got recommended to me, and boy this was a fantastic watch. I probably won't watch the almost 3 hour long version, but this was very informative; I don't think this version missed much from what's important and relevant so good job. Area Diesel Service, you guys have a beautiful shop setup and I will keep you in mind when/if I ever get around to playing with the injectors or the p-pump on my '95 Dodge - it's no unicorn with 350k but every time I work on it the truck runs better. I work in auto repair and the shop I'm with is focused towards BMW/Mini and euro imports, I can only hope someday that this shop or whatever shop I end up at can be comparatively focused and as specialized as yours is(that might be hard doing full service compared to a pump shop haha). Anyway, great video. I learned a bunch and hope you all keep doing well, great stuff.

[@garydahler8291]

I bet 100$ you watch the long video???

[@slypig24]

So very instresting to watch a injector pump rebuild. It's like watching brain surgery. Cheers from Australia 🇦🇺

[@999torino]

Another Wes fan here, man you folks do great work. So proficient at what you do!

[@handymandev03]

You guys Don't do good workmanship you do OUTSTANDING quality of workmanship. Wes knows you guys are the best in the business.

[@jaymoney119966]

I enjoyed watching this guy work a lot, didn’t skip a beat

[@pcspecialistpdx]

As soon as I saw how long the long version was I immediately switched to the short. I enjoyed it and wasn't left wishing I had watched the long. You did a great job packing the "12+ hours" into less than an hour video.

[@yourfriendlyneighborhoodic128]

why would it be a 12+ hour video for a 45 minute long job?

[@veejaybomjay8145]

Fascinating! a tip of the hat is in order for Gary The God of Diesel injector pumps. I have never seen a more knowledgeable or skillful professional.

[@JonatanGronoset]

Watching Gary go over that pump was awesome. I could immediately tell he's a professional just by his routines and it's enjoyable to see his skill reflected in his work. Good man, Gary!

[@johncole3883]

SO MUCH KNOWLEDGE AND PROFESSIONAL SKILL REBUILDING INJECTORS, ONE CAN LEARN ABOUT THE INTRICACIES OF A WELL BUILT, PRECISION MACHINE. I DO BELIEVE THE SOUND ENGINEER MAY HAVE USED SOME STIMULATING SUBSTANCE AND SET THE PLAYBACK SPEED AT 12.37% FASTER THAN NORMAL SPEECH.

[@calholli]

Everyone keeps mentioning the speed, but I still watched it at 1.5x on my end. Great video.. good stuff

[@MikeyMack303]

Excellent work! Clear, concise, very professional, no b/s. I chose to watch the condensed video. Thank you for sharing that with us.

[@Michael_CS615]

Long term corporate knowledge (EXPERIENCE) is so important at almost all workplaces. Keep the oldies and let them pass on knowledge. Youth might be good but never forget experience.

[@chazer200]

Gary is a irreplaceable LEGEND. Enjoyed learning how this pump works watching him. Thanks.

[@mdouglaswray]

LOVE the detailed explanation of the issue! The complexity of these pumps is impressive. Reliable if all parts are right, but fails in a distinctive way. Experience PAYS! Way to go Gary!!!!

[@davidcraig-browne3885]

What a great video - sped up where the work is routine but back to normal for the explanations. Watching an expert makes this complicated device look easy to diagnose - obviously not. The wear marks are very subtle but likely Wes's problem. as a special bonus Wes's lady remark at the end - excellent! Well done guys.

[@bradsmn]

Gary is one heck of an expert in his field of work as is Wes. Nice work.

[@tchads_57]

Will I ever work on any Diesel engine? Not likely. But I still enjoy his videos and now your. Thanks for all the hard work, both in the shop and creating the video.

[@johnblake3863]

Gary is amazing. My mind is blown!

[@mejesse809]

Maybe he could rebuild it?

[@danhei]

Would be nice to have captions on whilst the master craftsman was in the calibration mode. Didn’t understand a word of what he said. Cheers from 🇨🇦

[@XFolf]

Dang... this was a treat to watch, will keep watching.

[@COMM114]

Nice to see a competent shop at work. If anyone plans to retire, please start training up your replacement. It is scary to see what happens to an industry when real experience in workmanship retires.

[@whathasxgottodowithit3919.]

A true Master Technician at work, that is quality work. Great video

[@tedturner5881]

You never know the abilities of an expert till you watch one work and are able to marvel at the talent they have.

[@trep53]

Both versions were worth watching for me!

[@mejesse809]

I couldn't take another one

[@libertyhillbilly4158]

Love seeing a true expert at his/her craft and Gary is awesome. I prefer the shorter format video, just from a time constraint perspective...will definitely watch the longer version over the upcoming holiday, but usually don't have that time to devote to a video. Thanks for the awesome collaborations you are doing with other youtube channels....always enjoyable!!!

[@Loglakeliving]

Great work! I was impressed the first time I watched Wes at Area Diesel Service with his tractor’s pump. A master at work both guys!

[@adobedoug2564]

I’m really impressed with you guys. It’s really hard to find outfits that have the knowledge and attention to detail shown in these videos. It was Wes that brought me here.

[@karlaudi9104]

This whole process and professional partnership of experience and well earned and learned expertise between Wes and Area Diesel was a pleasure to behold. For me the icing on the cake was the memory of, and the reference too the TSB. Such organizational memory is beyond priceless and hopefully is always passed on to the apprentice working to be the next skilled professional.

[@45AMT]

Awesome video defintley wouldn't hesitate to send something to Area Diesel ! Their knowledge and expertise is mind blowing.

[@pinwizz69]

As a Veteran Coast Guard aircraft mechanic I've absolutely no doubt that if Gary had ended up a fuel selector (carb on a Turboshaft helo engine) overhual mechanic he'd have Aviation maintenance companies head hunting him offering peris galore with a higher than normal salary. He's extremely professional. Plus, he's a dead ringer looks, hand gestures and speaking cadence for my Friend and Deacon at my Church Lane Poole.

[@garydahler8291]

Thanks

[@mejesse809]

🤔

[@gs1100ed]

@@garydahler8291 Sir! I know nothing about these pumps, but can’t help but wonder what the failure rate is? They are obviously very complex ad therefore expensive to repair. Are these pumps superior to other diesel fuel injection systems? Thank you!

[@thirzapeevey2395]

Wes is amazing. Gary is amazing. The collaboration between them was a hugely educational experience. Well done. I still probably wouldn't have understood what was going on, but since I started building knives I have become very aware of how ductile stainless steel is, and that it can deform considerably.

[@kennethdavis9987]

Nice to see a butterfly impact!!! I have a MAC 3/8 i use everyday. Great video.

[@alltechinbox]

I am confident we are not going to have to watch Wes walk. Great work

[@bionicman6969]

These guys, especially Gary aim for absolute perfection in every minute detail. Grew up in a large family of machinists and watching this man do his craft is awesome. There can't be a lot of guys out there who could have found that tiny flaw, and the diagnosis of what caused the issue is fascinating.

[@MegaAaron42]

Always remember that new and good are not the same thing! 🍺

[@rickbaker4571]

The video is as tight as their work... these guys are ON IT!!. Fantastic

[@nashsmith3005]

This was very impressive 👍👏

[@dev-debug]

Not a diesel guy but like watching Wes work on them. I take it this is pre electronic fuel injection ? Seems like a crazy complicated pump o.0 Edit: That test bench is slick !

[@garyplewa9277]

Wow, what an education. I can really appreciate the precision and the experience required to work on these pumps. I have a 94 Ram 2500 with the 12v 5.9 Cummins and one of these pumps. With 300,000 miles it starts almost instantly on the first crank. Oddly enough my 1993 Class A motor home with the same 12V 5.9 Cummins and P7100 and only 40,000 miles very hard to start, even when warm. Good inlet pressure and no air leaks in either the fuel supply or return lines. I'm stumped. I'll be calling this shop for advice and service after watching this absolutely impressive video. Thanks for making it!

[@AreaDieselService]

Thanks for the watch Gary and give us a call anytime! (well M-F 8-5)

[@donparker8246]

An absolute professional.

[@dnixon8767]

Gary is a very experienced and knowledgeable guy. It is a joy to watch him work.

[@devmeistersuperprecision4155]

In my world, I have worked on Perkins, Cummins 5.9 and one Deutz. I have nothing good to say about the modern CP engines. I rebuilt a 97 P-Pump and installed it in my 99 24 valve. Calibration is a pain and you need a cal bench to do it right. I changed timing on mine. Machined a tool using a tenth reading Starrett gage to set alternate timing using barrel #1. Pull delivery valve and adjust gear placement accordingly from pumps TDC #1. I have worked on the English CAV pumps also. I love the CAV and P-7100 pumps. Schied reshimmed my injectors to pop off with the lower P-Pump delivery pressure. It’s a true joy to watch this pump being rebuilt. I wound up removing my solenoid and replaced it with a cable. I also had initial issues with the aneroid due to a striped bolt on the aneroid cover moving it out of position. I bought the pump used and the PO had striped it. This video was totally invaluable as I have never seen this problem before. I also replaced the fuel filter and lift pump with an original 12 valve FASS. You can’t underestimate this. The tolerances and workmanship of this pump is insane. The nozzles on those injectors are extremely tiny. The fuel in some Wyoming stations from old above ground tanks is almost like a slurpee! So super clean fuel is vital. Also, I am a fan of Rotella T4. Routine changes! I have seen 250,000 miles with NO measurable wear! Except for the valve guides which is the collateral damage from ultra low sulfur fuel. Machined 24 mag bronze guides and honed to 3 tenths fit. Keep up the good work guys!

[@tedbiernacki376]

Shmoo, gotta love it ! Gave me a chuckle ! It was fascinating watching the tear apart and then rebuilding, and then calibration of this pump ! Is it just me, or does the pump look like some sort of small scale engine!

[@mdouglaswray]

Amazingly thorough overhaul!!

[@corydriver7634]

This is an amazing process, looks like Gary has done this a time or three over the past 40 years.🤓

[@KyleMorpheus]

the thoroughness of your videos is insane. Love the passion in this shop!

[@davidhongkong5657]

An excellent technical presentation. Well done. I have seen diesel injector repair shops here in Hong Kong, but never had the time to watch an overhaul process. Fascinating!

[@wes11bravo]

Impressive. I wouldn't hesitate to send you guys an injection pump for rebuild.

[@mattmopar440]

WES sent me here :)

[@scotthicks8338]

I know you don’t put up videos on a regular schedule, but I’m always glad when you do. I’ll watch the full video tomorrow. 👍

It was such a pleasure to watch a pro at work!

[@dieseldoctor2221]

The best and only the best diesel service in the entire MIDWEST!!! HANDS DOWN!!!

[@kimazbell460]

I watched the short version after having watched Wes install the pump on the 95 Dodge. Extremely interesting and when time permits might watch the long version. Great job guys and it's a thrill watching true craftsmen at their work.

[@greggb1416]

Soooo, i note that “Gary”.., could probably do this repair/rebuild of this pump.., with his eyes closed, or in his sleep., or with one hand tied behind his back., or… I am mesmerized by “Gary’s” skills involved with this., also his narration of the process., and explanation of whole process. Excellent video. Thank you gentlemen.

[@mejesse809]

Yes, it's like riding a bike

[@thomasdesmond2248]

Nothing like a craftsman. Great job as usual. God bless

[@aaronhunt1616]

Awesome to watch either way and what a great service you all supply

[@cattlerepairmancattlerepai9414]

So great to see that experts like Gary Dahler with 40 years on the job are working on fixing delicate machinery like IPs. I guarantee that there is nothing this guy has not seen, diagnosed or fixed.

There's no guarantees in life

[@IHcubcadet]

Amazing work! Well done.

[@garydahler8291]

[@michaelnelson9140]

Gives you the reason why rebuilding these pumps cost so much.

[@mortoncopeland9905]

Really enjoyed this professional content !!

[@tylerbarrett6652]

I'm so glad you guys corroborate with other channels... so we can see the WHOLE process required for a repair. You answer probably every question we could have and I really enjoyed watching you guys do THIS portion of the repair. I hope that one day I will find such a unicorn... and if all it needs is an injection pump rebuild, then I know where to send it. Thanks for doing this for us.

[@tylerbarrett6652]

Which version is my preference? I really liked this one with excellent use of time lapse... slowing down to provide explanations. I liked having the choice, tho. I didn't watch the longer version as I didn't think I needed to; however, if I was trying to rebuild a pump like this one I probably would prefer the long version. Thanks for putting them both up... I think, so long as your video editor is okay with it, that you should continue to do that. So many things to do and so little time... for you guys and for us.

[@JustMike2791]

Excellent work, really enjoyed the test stand.

[@peteraitken6494]

Wow you guys are true professionals at what you do thanks to watching Wes channel I watched in awe at the the way you guys do things defo the real deal right there thanks for showing what you can do awesome once again and thanks to Wes whom is a great mechanic take care and may your business prosper 👍👌🔧🔧🔧

[@brianhind6149]

Great video guys. Let me just say that you both speak very quickly, which can be a problem to some viewers. I understand you are not in the business of making videos, but if you are making further videos, remembering to speak clearly & at moderate speed is important. Wes has sent the pump to the right shop. I have a 97 Dodge 2500 with one & one half million miles on it. The pump has never been worked on, & all parts are factory. This winter, I notice that if the block heater has not been plugged in for a couple of hours, It cranks & fires on several cylinders & as the engine speed increases, it picks up the remainder & idles fine. I think its time I sprung a few bucks for a set of replacement injectors..Bosch of course. . It is illuminating to watch the pump being worked on. Great work guys.

[@tcardinal95]

This guy is a unicorn! Thanks for all of the wisdom!!

[@richardcranium5839]

wes subscriber here. nice video on p pump breakdown and assembly. the test bench section may have been a little too abbreviated for viewers to see what really it takes to dial one in. am also shocked that you openly admitted to 10% upping the fuel. thats borderline epa violation on film. there's a tool for those tapered pins but it is not bosch. the one i've used may have been specially made.

[@lwoodt1]

When I put the play back speed on 0.75, it sounds much better.

[@garydahler8291]
