[@davidrobinson8408]

I used to do a lot of work on the 8.3 in sugar cane harvesters here in Florida. The biggest issue we had was head gaskets. The machine was using every bit of power they would put out. If they didn’t keep the radiator clean they would over heat and pop head gaskets. They would pour coolant out from under the head. I believe there was an issue with the gaskets and we put a new style in and did a different torque sequence. I got so good at head gasket jobs that I could drive a machine in the shop in the morning, pull the head, clean it all up, pit it all back together and drive it out by that evening. Sounds easy if it’s on a stand but we did it in the machine and the motor was in the middle so a lot of stuff to take off to get to the engine and climbing up and down on the machine. After that they were good to go. Also got a few reman engines they the rear main seal plate wasn’t installed correctly so the oil pan didn’t seal and they leaked oil like crazy. That was always a fun fix because we had the pull the engine which was a job. enjoy your videos.

Also there was an update to the headgasket because they were prone to leaking at the front right corner. The head is almost always flat but it chafed causing a leak under load. Probably fixed 200 of these in the last 15 years

[@poonbandit9924]

I’m the assistant service manager (basically manage the service writers and shop infrastructure) at a large diesel shop, I come from being a master auto tech so I know how Diesel engines work and understand it all and could repair one, but im behind the curve on common issues with these engines and the techs give me a ton of flack for it (Then I remind them who rebuilt there wife’s transmission or made a brake line for their truck and we’re even) but these videos make me surprise the guys when I know the common issues or the way things are set up and I absolutely love it.

It really depends on the wind, when the wind is blowing, you can expect around 9 MPG! I also run my diesel generator if it gets hot, to run the roof top A/C's! I have ran all the way up to Maine, and out to Custer, SD from central Illinois, and the MPG is always in the 9 to 11 range! My speed is around 62/65 MPH!

[@razor3003]

I've heard that from a few other people, I think that's pretty typical & actually not too bad, all things considered. Now all we have to do is get the cost of diesel back down to earth. Let's go Brandon!

[@BGGarage]

Regarding cavitation, it is the other way around as you have explained it. It is not when the coolant gets pulled away that it takes the metal with it. As the coolant is pushed away so quickly, a low pressure is created behind it causing air bubbles to form, as the coolant is getting pulled back in, the air bubbles collapse and the coolant itself impinges the metal, wearing it out.

[@joseywales2037]

more about electrolysis

[@RedmanAutoEngineering]

@deboss garage, I know one of the engineers that worked on the B series at Darlington and he maintains that the dowel pin is not an issue until people start replacing the injection pumps and do not refit the support bracket correctly on the injection pump or in some cases not at all. The increased moment on the timing case causes movement and it works the dowel loose. Theres a service bulliten on this particular issue on the B somewhere.

[@shawncooke3629]

The failure of number 6 cylinder is helped if you add a water aid to the rear of the head like the marine engines. The injector pump on the engines less than 350 horse have 10 mm plungers 5.9 has 12mm. Older cool blocks have thicker lines and thinner blocks that tend to cause block failures behind the injector pump caused by the clamping force of the head bolts on the cylinder counter bore.

[@sixtyfiveford]

7000 hours isn't much in the way of road miles if you want to compare it to vehicles. It's only around 300k.

VP44 and CAPS are very different and failure mods are very different. The problem with CAPS is mainly confined to the pump and surge suppressor/ transient diode. VP44 is the one with fuel lift pump problems. Most issues with CAPS were resolved with later changes. Though they both use the same lift pump design you are less likely to kill a CAPS pump with lift pump failure.

[@Sbanar]

That dowel on the B series only comes off if a fuel pump or compressor is mounted incorrectly causing the timing case to flex over time. It will never happen in a stock engine, hence why Cummins never issued a "fix" for it.

[@markcli5950]

8.3 is the engine found in the Military 5 Ton's, 80's to 1995

The 8.3L 6CT is actually in the M923A2-M943A2 five ton trucks for 1987 to 1994,those trucks were made by BMY Harsco too,but you are correct,just off by some years. The M923-M943 & M923A1-M945A1 which came BEFORE the M923A2-M943A2 going back to 1982 all have the 14.0L NHC-250,and the M812-M820 used the same engine in early years too.The M923-M943 and M923A1-M945A1 were made by AM General too,and it's easy to tell the difference between the three variations of those trucks,the M923-M943 has G177 dual tires which are 42 Inch (1100×20) and then the M923A1-M945A1 have super single Michelins "XL" that are 48 Inch (1400×20) and finally,the M923A2-M943A2 also have super single tires which are 50 Inch. The reason why they stopped production for them in 1994 was because of the Stewart & Stevenson M1078-M1088 FMTV,at least in the Army.For the Seabees and Marines,the Oshkosh MK23-MK38 MTVR came out a few years later,which replaced the M939 Series.

Our r65 gleaner has the caps 8.3. When it runs good it really runs good. However when gleaner bought these engines they did not get software diagnostic capabilites with them. Means having to deal with a Cummins dealer 2 hours away rather than the gleaner dealer 15 minutes away.

Awesome Rich thank you..............so clued up on these diesel behemoths

[@davey_projects2977]

That sleeve removable tool would pay for itself in like a week at a shop. Great idea.

[@Northern_Farmer]

I have the 8.3 In my 1994 CaseIH 7120...... Been a great Engine but why do they always leak on the front covers!! My 5.9 Is leaking oil to!

[@MitzvosGolem1]

I love Cummins. That ceramic injector issue was a disaster though on Common rail new age motors. I had a few L10 and M11 in cranes. Excellent engines.

Great informative video @Deboss Garage

[@elljay4587]

You do a great job. Very informative

[@DEBOSSGARAGE]

Much appreciated

The US Military used the 8.3 in the M939 series 5-ton trucks made by AM General. The rated horse power in that application was 240 hp. The 8.3 was significantly lighter than the NHC-250 the 855 cubic inch NA engine that it replaced . The weak link with the engine in military application is the water pump and the steel line used for oiling the turbocharger.

[@Slim_Slid]

You are correct,but the M923A2-M943A2 was not made by AM General,all of them were manufactured by BMY Division of Harsco actually.The M923-M943 and M923A1-M945A1,which had the NHC-250 were the only ones made by AM General,the A2 was only for 1987 to 1994,the first M939's and then the A1 go as far back as 1982,the A1 came out in 1984/85.The NHC-250 was also the only engine ever used in the M812-M820,for 1969 to 1982,and they were all manual,they did not have Allison Automatics in the M809 trucks like the M939 trucks do. Those trucks also had errors with rusty springs in the Overflow Valves and some of them not having Hydraulic Hoses,which were always better for them.For the most part,they had issues with the fuel systems in the long run.

What's wrong with an 8.3 Cummins? It's not in my 2nd gen, that's what. Edit: Hell, put that old bitch Inna C5500!

Very nice liner puller tool kit

[@daviddrosendahljr6985]

Alot of good info, the issue I have with the c series is that the exhaust manifold bolts are a nightmare to remove without breaking them off in the head, there stainless which is great until they gaul in the head just from the constant heat cycling. Other than that great video!

Cannon, back in the mid 70s I would put up any Bulldog engine against any cat engine, so a Dog, I'm my opinion was better than a cat .

I think Cummins offers this with the pod system for retrofits in bigger boats, think 50 foot sport fishermans.

WOW - thanks for class 101 on this engine. Great help to ask the right questions. THANKS !

I agree with ya mostly ! We put sleeves in a 5.9 Cummins about ten years ago still running today lol
