How many hrs are they good for assuming regular maintenance. Oil changed etc. Do they throw rods,burn pistons,drink oil? What? Anyone ever OH one?

I run 2 R62 s with the 8.3,my original one has 8000+ Engine hours and 6300 rotor hours. I had to rebuild the motor at about 7000 hrs because they have an idler gear between the crank gear and oilpump gear and the idler broke and i lost oil pressure. Caught it quickly,but still lost turbo,it locked. Pulled motor down completely and liners where perfect still, so new orings on liners,piston rings and all bearing shells,plus seals gaskets ect. I disassembled the head and all valves and valve guides were all perfect. Very good motor with mid mounted liners ,so no cavitation pits at all on the liners. Dont know why the idler gear failed but otherwise couldnt fault it.

Stay away from the ones with the caps fuel system. Other than that they're good motors. In fact stay away from any cummins with the caps system. Edited by Kansas99 - 03 Dec 2020 at 6:44am |

This looks like P pump with aneroid valve period. Seen a caps once and this doesn't look like it. From serial # it's a 97

Caps was only used for a few years, on r65 first few years before sisu motor. I don't think it was ever on a 62

I had a 2002 R62 with the Caps Fuel System, also a 2005 R65 with the CAPS. Marginal fuel system as its best. Head gasket coolant leakage to the outside of the engine block is common, pretty easy, straight forward repair. I always used genuine Cummins gaskets and bolts if needed. 8.3 mechanical is a good and reliable engine. 97 R62 will have the longer shoe which it needs. Good Luck, Mike

Know of a few overhauled in trucks, not farm equipment. Each one was complete overhaul, had been run hot. Have encountered several in farm equipment with head gasket issue, not a hard fix at all. 8.3 are good solid engines I think. Start great, run good, and make solid power.

At one time around here we had 8.3s in the combine,grain truck, and the 4wd New Holland. Combine had a little over 3500 hrs when we traded it off. It’s still going. There’s a lot of trucks with 8.3s with a lot of miles on them. A good solid engine.

Nothing wrong with the caps fuel pump. It’s only limited by the people working on it that have no clue how to make it work.

Caps is basically a high pressure pump like common rail but has a distributor instead of a rail and poppet injections. The injection control valve interrupts fuel flow between ports in the distributor. There are 3 basic parts to the pump assy. The pump next to the gear housing with the big block on the top that holds the pumping chambers and “fill valves”. The injection control valve located between the big block and the distributor housing. And the distributor housing hanging on rear of pump housing. The fill valves open to allow fuel into pumping chambers The time open is related to pressure required. The icv interrupts fuel the pump builds as needed to change timing and stop flow between ports as the distributor rotates. They are really simple but the diagnostic steps are more of a good guess than direct steps. There are parts in the system that aren’t talked about or tested in diagnostic and that is what will cause most people trouble when troubleshooting

All in the name of what? Emissions? Economy? Cousin had to have that replaced on his 65. Was over $1500 I think for part alone. Makes no good sense.

That was probably those porcelain parts in the head fill valves or pumping chamber or whatever that crap is. They're supposed to be lubed by fuel, did it 3 times on my 65 and then finally spent $5k on a whole new pump and know it throws codes that there is air in the system but everyone throws there hands up now. My brother had a CaseIH 4wd with a cummins with a caps system, worked on it for years, in a last ditch effort tried to put a mechanical back on the motor but never worked, he sold the tractor on auctiontime. It didn't bring much as everyone already knew about caps. I once called cummins about my 8.3 and when I told the guy it had a caps he said "UH OH" They didn't use it long.

The CAPS was Cummins' answer to the Bosch VP44 used on the 5.9. It looks nothing like a P pump though, except it uses a P pump mounting flange, so that is why there have been shops develop kits to put a Bosch P pump on those engines. I've heard they had other issues though, never been involved with one, no time to get involved lol! The injectors are still a typical injector and look just like ones from a 24 valve 5.9 but taller. I think there's a few injection shops that service those pumps with some success. I'm not one of them lol! I know better than to even mess with one.

8.3's had a front cover leak problem, we had R62 &they fixed that when we got it. We now have R65 w/Sisu, about a third less fuel. Both engines perform well but can't believe the difference in fuel consumption.

AGCO also used a similar designed injection pump on the SISU tier 2, 8.4L engines. We have one in a tier 2, 240A Tractor. It's been really dependable except for one catastrophic inj. pump failure years ago. It was maybe 5 years old, took it to Diesel Specialties, Sioux City, 1,500 dollars later still running strong. Engine manufactures were trying to catch up with new EPA mandates and use these designs until common rail technology was developed and became widely adopted. I have vivid memories of waiting for Cummins Central Power Service Tech to show up and diagnose fault codes on my under 200 hours R62. All while our other 1999 R62 8.3CTA continued to hum along. , Mike

Well I own one and I can tell you that in 4500hrs. it has been worked on 3 times by a agco dealer, once by a pump shop, and once by cummins and $8k later it still is not right. So I will knock them because they're junk imo.

I have an idea. Why don't you offer some help/guidance on the much hated CAPS fuel system instead telling everyone they are "stupid". You must be one of a few who know why they are not a problem. That system has cost alot of people alot of money and still a problem. When "qualified" people can't fix it,there's something out of whack.

Ok ask the tech working on it where is the transient suppressor. If he can find it and a part number he might have a clue.

I like the KISS rule. If it's difficult, not to mention expense, to service then there might be a problem even if it "can" be a good system. Like a Deutz engine.

Both my engines run the bosch inline pump.only bad thing id say about my 8.3s is that they love to drink fuel. I use alot more fuel at harvest then at seeding time.

My F2 uses less that 2 gal per acre...an 8.3 R62 would suck compared to that! Oh well.
