[@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

I just woke up and wanted to watch videos on my RV engine. Had a coffee and enjoying learning about my 94 C series. It's been a great engine although you should keep an extra cog belt around, I sourced a couple off ebay for less than $200. I had to get one replaced by a roadside mechanic once out on the highway in the middle of nowherevill Kentucky and I ended up paying $1,200 to replace a belt. Took one tool and a belt.

[@billygreenhorn9275]

[@pauljfrenchtrucking3408]

would really love to see you do a review on the L10 cummins. and you do a great job of explaining everything, thanks i have learned alot for watching you channel.

[@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]

We use to use the Dongfeng-Cummins 6CTAA8.3 in our 200kVA gensets (moved to Perkins 1106). They worked very well and could do high hours but with a lot of the Dongfeng-Cummins, they leaked oil, in particular from the oil cooler.

[@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.

[@thesunflowchannel1995]

Thank you for teaching me about the 8.3 6CT engine very interesting

[@mikeytows]

i believe the cavitation is from the intense combustion (slight pre ignition) of a diesel ringing the cylinder like a bell, not the piston rattling. I read that somewhere. Great video.

[@boB7710II]

[@juryrigjohn9697]

I'd like to see you do a dt360. Heavier than a 5.9 but the wet sleeve, and I've seen guys make crazy power with them. Still research stage but I'm thinking better swap than a 12valve.

[@punkrocker10115]

I love that you're honest about these engines. I'm a cummins guy for life but, even I know(lots of firsthand experience lol) that they have somewhat annoying issues..😂😂

[@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.

[@pkuudsk9927]

[@pintmarten2403]

I've seen the CAPS pump used until late 2006 on the 225-260hp ISCe used in the Dennis trident II double decker, They are surprisingly fast even with the Voith D854.3 .

[@tylermorrison3654]

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.

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. Every few days during harvest I'm driving the combine with 1 hand and using my phone internet searching the latest trouble code set with the other.

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

[@Slim_Slid]

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.

[@thedieselguru6881]

I know it's a little newer than what you like working with but what about an LML Duramax motor??

I'm filthy but not rich so I must be doing something wrong lol.

[@bobwhite3777]

Your rich in the ways that matter.

[@thesunflowchannel1995]

josh33025 haven’t been filthy enough or maybe you get filthy and clean right after

[@Beandiptheredneck]

josh33025 are you not eventually cleaning the filthy? People might think your a bum?!? 🤣 I’m always getting filthy but I’m never rich too..

[@thesunflowchannel1995]

OntarioRedneXXX No you gotta stay filthy to truly be rich. You want people to think you’re a bum. Cleaning up just means you wasted all that filth and you’re left with nothing but peoples opinions. Doesn’t matter what they think

[@rebelcowboy5.7l98]

Its like that sign i just saw. Filthy. Stinkin. Rich. 2 outta 3 aint bad.

[@spicersgarage6470]

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

[@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.

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.

On the last 8.3 i worked on last year i just used a cat sleeve puller. The puller's feet just fit on the engine deck but it work fine. You just got to make sure that the pullers "hookes" that go on the bottem of the sleeve dont touch the sleeve retaining webbing in the block, if it does it would damage the puller and the block.

[@heavymachinery2843]

Very interresting liner pullers i really need to get one like that 😁👍

[@johnburns3390]

Cummins NTC/E Big cam

[@bryandegone8195]

[@Jordo4998]

ALH was the best.

[@bryandegone8195]

Yes it was!

[@02watsot]

I'd also argue a asz pd130 with no emissions bollox and a straight pipe with a medium-heavy map on it 👌🏻

[@MitzvosGolem1]

Check it VW has plastic water pump impeller failures alot.

[@justinmartin8887]

Yup alh for the win. The bew is shit and the commonrail is only marginally better

[@russian06374]

Been waiting for this video I've wanted to swap one into an one ton square body I've seen some cat 3216s and 3208s in them didn't realize the Cummins weighed that much more

[@will485948]

I put a cat 3116 engine 1981 Chevrolet square body. It weighs about that much to. I upgraded the suspension to the 10 lug

[@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.
