Looking good that engine, from a time the engineers had more to say than the financial people at mercedes. Keep up the awesome work. Looking forward to the next episode 👍
+1 ; If you don´t re-hone the cylinder walls, the new piston rings can grind away the rest of the old hone surface. Result can be high oil consumption and/or piston seizure (Kolbenfresser)
I'm a diesel engineer from 40 years back and have just rebuilt fully an OM621 . I kind of skipped through your video so apologies if I may have missed it. I didn't see any honing or glaze busting prior to fitting new rings. I didn't see you check ring gaps. I didn't see you measure ring groove particularly top ring in groove. Piston wear in bore. I didn't see you check valve guide wear...infact I didn't see a vernier or set of feeler gauges or a micrometer. The rings cannot bed in on a well glazed bore. I'm still learning too every day and it's exciting to put up your video but you perhaps need to do more research and read the om617 workshop manual to avoid these basic errors and ommisions. Cheers.
this was your opportunity to balance the rotating assembly MB has a 12gr + or - tolerance.I built my om616 with .1gr of tolerance in the pistons and crank. My pistons were good too but might as well since you have the thing apart. cause I'm never going o rebuild it again well maybe after another 300 k miles.
Greetings from Kenya! @2:04 I see you guys were giving South African music some love! I am also restoring a 300GD but mine is not as crazy as this one, but got some ideas from you guys! Where did u get the prefab panels tho? Fantastic build!
I think the OM606 would have been our first choice for a swap. But this engine seems to be in good shape and we're kinda curious to find out what it can do with the STT Turbo Kit and some tuning of the diesel pump.
Theirabouts yes. We're hoping that with the right settings on the dieselpump we'll be able to make some good usable power in the 120-130hp range. One issue is going to be keeping the heat in the rather small engine bay down, so we're thinking on going for a bigger intercooler down low underneath the radiator.
The original one has a fair amount of rust holes at the top, so we haven't had it powdercoated yet. Might be worth going for a plastic aftermarket one. What do you think?
Hi guys 👋 I’m no expert on the matter of fuel tanks, but I did have the opportunity to do major surgery on my w460/280ge. After washing and cleaning the ¡#!% out of the tank I opened it with a saw-zall. The bottom part of the tank was as smooth as a baby’s bottom. The upper part of the tank, however was a whole different story. Because of its “saddle-like” design the condensation apparently finds its way to the top (getting TRAPPED in those three upper pockets) gradually wreaking massive damage. And that is how Thor got his CANCER too!!! I thought of many ways of remedying my situation: a friend suggested an interior bladder…another swears by a steel made tanks and I, in my infinite wisdom thought of using a product called POR15 used in maritime works. I purchased the kit. Now I would have to cut and reopen the tank, clean it again and apply the 3-step process. It all sounded good until I thought of rewelding the tank closed, wherein I would probably most surely ruin whatever interior coating I had just applied…. I just had Chinese and my fortune cookie read: ¡Confucius say…what is the stomach’s importance to a good digestive system and overall health?😂 so… ¡I VOTE YES 👍🏼 GET THOR A NEW PLASTIC TANK !!
Isn’t this the same motor that enabled ‘Otto’ to travel 900,000 km in 26 years? Not even Mercedes makes them like that any more. I’d be wary the replacement parts were not as good as the originals.
Nice work! You might be the only guy who's taken a om617 apart like that and put it up on youtube.
You think so? We honestly haven't checked. That would be awesome though!

Thanks Bas. Thats right.
Ein beeindruckender Motorblock. Und am Ende ist keine Schraube übrig geblieben. Tolles Puzzle.
Die übrig gebliebenen Schrauben hat Lasse gut versteckt. Danke Cäcilie!
Good job!
looking forward to the next installment😃
Thank you!
I'm no diesel mechanic but with new rings you usually want to hone the cylinders so the rings can break in.
I'll ask my brothers reasoning behind that and get back to you.

Hah! Do you even know what a cylinder is?
You should put an OM606 for this one. Magnificent job with with the restoration !
Cool Lasse 😎 !
cant wait to hear that beast
Stay tuned.
You guys are crazy and really smart. This is really entertaining.
I would have to disagree with the "really smart" part but appreciate your kind words, Michael!
I’ve been talking about this really looking forward for the next episode.thanks for sharing
Thank you Joel! Appreciate your support.

nice vid. I am putting my om617 back together now. i think i want to get the ip worked on to make more power and a newer turbo
Hello guys. We're the piston and crankshaft shells replaced prior to reassembly? Great project boys.
Just found the channel, cool project! Question: Why not hone the block when you have it all apart anyways? Looking forward to more!
Como poner a pronto motor 617 para poder montar la bomba injectora motor de 5 cilindros disel

Thanks Tirus! Would love to come to Kenya for some 4wding some time! The panels we bought of ebay. I think most came from Poland.
. . . ja gut, dann geht was.
Das wollen wir hoffen!
I'm surprise617d you didn't buy and install an OM605turbo instead of that heavy lump of OM617.
I think the OM606 would have been our first choice for a swap. But this engine seems to be in good shape and we're kinda curious to find out what it can do with the STT Turbo Kit and some tuning of the diesel pump.
i need your help! im planning to do a om617 to my landcruiser can you guys guide me
Technically a om617a
An aftermarket 617a
Technically an aftermarket 617la with the small intercooler.
@@jonasfreitag a big improvement on the 88bhp of the naturally aspirated engine, circa 125?
Theirabouts yes. We're hoping that with the right settings on the dieselpump we'll be able to make some good usable power in the 120-130hp range.

Hi guys
¿Is Thor getting an original fuel tank(s) or an aftermarket…?
The original one has a fair amount of rust holes at the top, so we haven't had it powdercoated yet. Might be worth going for a plastic aftermarket one. What do you think?

@@berniereyes1956 awesome Bernie! Thanks so much for your insight. We’ll definitely be looking into that then.

It sure is, only that ours has a STT turbo kit installed.
