Dear Friend,
Thank you very much for uploading the information of V8-71N Detroit Diesel Engine .
It is very useful for me. At present i am working in this engine which was discarded. There is no information plate on it and its powering a 125 KVA Genset.
Would you be kind enough to furnish me the firing order and the part no of the injectors of this engine. 2 of its cylinder is firing less.
I feel that this engine requires Tappet Setting.
I sincerely hope that you will help me out.
Hope to hear from you very soon.
With Regards
Yours truly

Hi Ben
Re: 8v-71 Engine
I'm pleased our site was of assistance to you.
The firing order is shown on the webpage for the 8V-71, and there is also an image there for your orientation. Check this URL in case you're working from an old one:
http://barringtondieselclub.co.za/8V71DetroitDiesel.html
Just in case you don't see it press Ctrl + F5 together to refresh your screen.
The most common injectors are either N60 or N65 for naturally aspirated engines, and N70 for turbo charged engines. If you look on an old injector you'll see a tag on it with one of these numbers, or something similar, Any Detroit stockist should be able to help you with just that number. But if they can't help you, give me the tag number, and I'll give you the correct part number.
Also if you're stuck for anything, we can supply from South Africa or from USA.
If you want more information, just ask.
In the meantime, if you want to say thanks, I'm just getting Facebook started on our web site, but I need some 'Likes' before they give me the proper buttons, so if you're on Facebook, (and your friends can do it too), log into your account then on the Search bar, type in 'Barrington Diesel Club', when the page comes up, 'like' the site. Also you can 'like' anything on the site as well. Simple as that.
That will be most appreciated,
Thanks

Ben gave us a 'Like' - Thanks very much Ben
My ADE 423 has just been overhauled and its vibrating terribly, what can the problem be?
Hi Alan,
Re: ADE 423 vibration, your telecom 22nd Sept 2011 refers
Please find attached a fault findingchart for the ADE 420 series.
The chart shows 13 possibilities for vibration, but that's normally for vibration that occurs assuming that the engine has been correctly assembled in the first place.
However for assembly faults examine:
Otherwise you'll have to work through the ADE 13 possible sources of vibrationuntil you find the problem.
Kind Regards
Steve
Thank you very much for all your valuable information. I will let you know the outcome, probably Wednesday.

Alan
Hi Steve,
thought that I would keep you in the picture.
I sent the crank, flywheel and vibration damper away for balancing.
When the guy saw the crank he immediately commented that the weights were wrong.
He says that the mechanic doing the work muddled up no 6 and no 9 weights.

Alan
Hi Alan,
Thanks for your feedback, I do appreciate it. I would like to post this conversation onto our weblog, (without revealing your email or company address) as I'm sure it'll be of interest to many people. Let me know.

Good day Steve,
I am doing a little research in the hope of purchasing a nice classic American Semi from the 60’s going into the 70’s and I was hoping that you could assist.
Were the Detroit Diesel 8V71 N/T engines used in any significant number in South Africa over the years? What would be the likelihood of finding a piece of Americana fitted with one of these beauty’s here in South Africa at this time?
I have found your website to be most interesting and educational
Kind regards
Andrew
Hi Andrew,
Re: The Great American Semi
Thanks for your interest and acknowledgments.
Very few on-highway vehicles were fitted with Detroit Diesel in South Africa over the years. The railways had a fleet of Eagle buses with 8v-71's, and several local councils ran trash collectors, Internationals, with 6v-53's, but no concentrations of American Semis that I'm aware of.
The 8v-71's in SA were mostly used in industrial or earthmoving applications, and there are still a few around now. Detroit 8v-71 parts are still freely available in South Africa.
Over the years truckers and other enthusiasts did bring in a few semis but they were probably mostly Right Hand Drive units.
I asked a friend of mine, Mick van Rensburg, about your email. Mick has been, inter alia, involved in and still maintains an interest in racing Detroits and other things at the Tarlton race track near Krugersdorp over the years.
Mick has a couple of trucks at Tarlton, I don't know if they will meet an enthusiast's qualification, but he said you can phone him if you want.
Another possible source for a truck would be D&O in Elandsfontein, they have a number of old trucks in their yard. You can speak to Frikkie Odendaal there.
Kind Regards
Steve
Steve,
I'm Jeff. I'm working at the Naval Post Graduate School in Monterey, California. I'm trying to find out a rather arcane specification for a Detroit diesel 3-53, 5033-6299. Specifically I'm interested in the clearance volume between the piston and cylinder head when the piston is at TDC. I'm having a difficult time finding this and am hoping you may have this information. I appreciate any help that you can provide, Thank you for your time.
Hi Jeff
Re: 53 Chamber Volume
Thanks for writing. I love these questions. The theory is basically very simple, which once gotten can be applied to all engines. You need engine bore, stroke, and piston ratio for the calculation.
Our website shows:
53 bore = 3.875 inches
stroke = 4.5 inches
ratio = 21:1 (for naturally aspirated N engines)
We apply that information as follows:
Cylinder Volume = area*stroke
= pi*r²*4.5 cu inches
= 3.1416*(3.875/2)*(3.875/2)*4.5
= 3.1416*1.9375*1.9375*4.5
= 53.0696 cu inches (hence the term 53 series engine)
Now, for me, when I use words like simple, easy, I often make a mistake, which I did. I gave Jeff the wrong formula and I had to write to him again to correct it, but I'm not going to give the wrong data again on purpose, so I've had to alter the correspondence here accordingly. Mea culpa.
My 'Auto Math Handbook' defines Chamber Volume as follows:
Chamber Volume =
Cylinder Volume
Compression ratio - 1.0
Now for the 53 N engines:
= 53.0696
20
= 2.65348
For the record here are some of the other relevant formulas used in the 'Auto Math Handbook', I list them to avoid terminology variances and therefore confusion:
Compression ratio = Cylinder + Chamber Volume
Chamber Volume
Cylinder volume = pi/4 * bore² * stroke
Kind Regards
Hi Steve,
Thank you so much for your help. I greatly appreciate your passion and meticulousness. Regarding the clearance volume of the 3-53, does the curved surface of the piston affect the overall volume, or is that taken into consideration with the compression ratio? Does the 3-53's piston even have a curved surface? I realize some pistons have a curved/warped surface to better mix the fuel when in motion.
Regards,
Jeff
Hi Jeff,
Re: Help acknowledgment.
You're welcome, thanks for the acknowledging comments it always makes a difference to receive such.
Re: 53 Piston Dome
I attach a photo of a 53 piston and liner, and another photo taken from the 'Auto Math Handbook' with examples of different domes on pistons.
Yes the domes are always taken into consideration when defining the chamber volume, and there are various methods to measure its volume and to make adjustments to the compression ratio.
Racing enthusiasts are forever playing with compression ratios to get more power or torque. The 'Auto Math Handbook' I've mentioned has a good simple introduction to the subject, that book has been a treasure to me over the years. Published by HPBooks a division of Price Stern, Inc. Los Angeles, California, author John Lawlor 1991/2.

Dear Steve.
I was just reading on your website a report on ADE.
So are they shut down now?
Is there a way to buy the old Mercedes Om447 from anyone out of SA? Maybe CA?
Best regards
Werner
Hi Werner
Re: the Om447 and the ADE447
Unfortunately you are correct, ADE does not exist any more except as described in the article you quoted.
The 447 is a much loved engine, but I don't think anyone in the world is making it any more. It seems that the Om457 is going to replace it. Manufacturers are battling to conform to the new and future emission standards in Europe and the USA, and in their efforts to get there we're going to see whole new families of engines around.
The image below was copied from "IDEM - The Iranian Diesel Engine Manufacturing Company" you can get them on the following link:
Iranian Diesel Engine Manufacturing Company
who are making the new engine in Iran.
Regards buying the Om447 new, I suspect you may find the odd pocket of engines at various dealers especially in Europe where Mercedes are massively strong, but you may need to ask Mercedes (try them in the UK) for a list of OEM's and dealers who purchased large quantities of engines. e.g. 'Toyota in SA were still selling new ADE engines a couple of years after ADE closed'.
Kind Regards
Steve
PS
We can, as others can too, supply you recon ADE447 engines on a one of or two of basis, but you'll battle for more than that.
Please supply us with the specs and interface drawing of a ADE 447 TI engine.

Hi Christo,
Re: ADE 447TI engine
Thanks for your inquiry
I have posted general ADE dimensions and power charts for the 447, 447T and the 447TI onto the website, you can get it at the following link:
Links to ADE engine specs
Click for larger image:
It is the ADE header page of our website. If you don't see it right away - press CTRL + F5 to refresh your screen.
I may have to move it soon though, because it takes too long to load where it is. However it will be there long enough for you to copy and to use. When I change it there will be links to the right pages anyway, so you don't need to worry.
I'm sure as an ADE specialist you know ADE info is difficult to get hold of, and I would like to post more specs on the 447 on to the website, so while I'm writing to you let me ask, have you got a 447 shop manual I can buy or copy?
Trust what I have will be of use to you,
Kind Regards

HI,
I would like to know ,on a Cummins big cam 400 hp on the camboxes must it be shimmed for a certain lift ,if what must it be? Can you please advice.
Country: DRC Congo
City: Lubumbashi
Name: Pieter
Hi Pieter,
Re: Big Cam - cam box shims.
Yes, the cam boxes are shimmed, and there are special tools to measure it. Normally if you measure the thickness of the old gaskets (shims) and either don't replace them or replace them with the same thickness gaskets (shims) you'll be OK. The last one I did was 0.050 thou", but cam keys, cam shafts, and cam and roller wear plus push rod length differences guarantee almost every one is different. If you haven't changed the cam or disturbed the cam keys you can try:
Kind Regards
Steve
Hi Steve,
Thanks for the help....their are no shims , as both were stripped totally ,I received it that way
It was lying in barn for a few years,,,,,,,,Let me just give the picture how I end up in the Congo
I came here 5 years ago from bell Equipment, resigned after 3 years,to start an Automotive Machine shop
That's 2 years now,,,,I'm an automotive machinist by trade , although after trade test start working field service
On earthmoving,,,,,,,,at 48 set up this setup. I'm the only shop in a vast country,,,,
Come visit ,,,,Catch Tiger fish , I'll sent you some interesting photos
Love to, thanks for sharing.

Feedback: Can anyone give me the GPH used by a naturally aspirated Detroit Diesel 3-53? It is used in a 50 year old sailboat and is running around 1800 rpm.
Is the weight of a naturally aspirated 3-53 about the same as a 3-53T, around 965 pounds?
Thanks

Hi John,
Re: 3-53T weight
3-53T spec-sheet weight = 1000 lbs or 455 Kg
Re: 3-53 fuel consumption
I've extracted the following tables from my notes. I have not checked them against other data, but should nevertheless answer your GPH question.
Those tables are a bit modified now, because while we're busy with it, we might as well update the 3-53 Detroit Diesel Specs at the same time:

Hi Steve,
I hope that Matthew enjoyed it, I know that it is not everyone that enjoys the music of an engine. I have downloaded some more on the old engines and will bring it through one day.
There is a meeting at Vereeniging at the Vaal the first weekend in September, Wheels on the Vaal at the Vaal technicon and there will be old engines, tractors and cars. My intention is to take the Detroit to one of these shows when it is running again one day. Everyone else is collecting old farm engines but no one is really into the old industrial engines, so maybe it will work.
I will keep you up to date what is happening this side.
Regards
Johan.
Hi Johan
Matthew gave me your YouTube discs.
Thank you very much, we greatly value data, discs, workshop manuals, spec sheets and so on.
Once again thanks very much.

Good day Steve
I hope I find you in good health.
Steve please advise me as I need to buy a 6 cylinder engine for my Toyota Coaster minibus. The engines available on the market are as follows:-
1 HZ ; 1 HDT; 12HT and a 15B. The ideal engine should be capable of delivering more than sufficient power and should be economical on the fuel side.
Further more the service spares should be readily available; and it should be easy to maintain
I value you input greatly
Many thanks
Humphrey
Hi Daan,
Thanks for your inquiry.
I have changed the index and added/changed a couple of items to the ADE 407 specs. Crankshaft end play is an important one that was not there.
Regarding the 447 engine - I have not got a workshop manual for this engine, but you can safely use the ADE 407 torques and clearances here.
The main differences between the engines are:
Full specs is a bit beyond the scope of what we are trying to do on the web e.g. the 407 full specs (what I have) are 10 detailed pages long. If you want them, please sign up as a member, cost US $15 per annum or R 105.00, & I'll email them to you.
Kind Regards
Steve
Hi Steve,
Please could you send me the full specs for the above engines.
I need all the torque specs, tappet clearance, injector timing, free play on the crank.

Anyone suggest anything?
Question, 20th July 2011, from, Chris, Re: Re-power
Hi Steve
I have a 454 90s Chevy that I use to tow a race car around. Next years national circuit is going to eat the budget on gas alone. I need to try and make the car as economical and durable as possible.
I read people switch the motors into this vehicle Cummins with expensive adapters but easy to setup and duramax no adapters but electrically very difficult.
The gearbox is a 4L80E.
I cannot afford a new engine as much as I would like.
Please advise
Thanks
