Lombardini 9LD - Urgent question

[Anorak_ian]

Hi guys,Does anyone know if a Lombardini 9LD twin will rev to 3600rpm?
I remember seeing one with 3600 on it's vin tag, but I can't be sure.

I don't want to buy this until I'm sure I can use it.

Cheers guys.

Looks like the 625 is run at 3600

But, the older 560 is listed as running at 3000. The guys over at Smokestak say all the Lombardinis can be dialed up to 3600. For what it's worth.

Hi, thanks for the reply.

I saw this website, but I think it's a typo as it is the only website with this info on it.

The second pdf dosen't work.

Cheers Ian

Odd that it doesn't open. I wonder if it's blocked on your side of the pond. Below is the paragraph from the service manual related to engine speed.

That is good news thank you.

The second pdf works for me???

Finally got it, I used a different internet browser.

Damn this info is for the 1120cc, I hope it is the same for the 1250cc.

I have the workshop manual for the 1250cc but it only states it can run at 3200rpm. Maybe it's the same adjustment and they just don't want to let people know it can rev higher. Crazy as that sounds, it may just be that simple.

It's a damn good engine, it has an alloy block (not cast iron), 28.5 horse power @3000rpm so at 3600rpm it has to be around 33 horse power. With a turbo that moves it up to around 4000 to 4200rpm and about 38 horse power.

The power take off / flywheel is on the left hand side (as you sit on the bike), so you can balance the bike well with the engine over to the right of the bike. At the same time the primary will line up perfectly. The only problem I can see is, finding a frame to fit such a tall engine.

Thanks for your help.

On page 76 the manual notes that the "Full speed setting in no-load conditions (standard)" should be set by an authorized Lombardini shop and to do otherwise will void the warranty. Leaves one with the impression that it's possible to dial it on up to 3600. And then what does "(standard)" mean???? Do you suppose 3600 would be the non-standard setting???

I think a definitive answer from Lombardini is the only way to know for sure. But if they will even reply to an email is anyones guess.

Ian the engine does not have alloy cylinders, cast iron. It is basically just a bigger version of the ruggerini 950. With the issue of revs, the engines are used for powering hydraulics or gen sets. With gen sets you either want 50hrz or 60hrz depending which side of the pond you are on, but I am sure there is no difference.

Hi Sam, So many engines have cast iron blocks (crank cases) these days like the 3 & 4 cyl Focs jobs. And they weigh a ton.

50hrz being 3000rpm and 60hrz being 3600rpm?

Did the rug 950 rev to 3600?

[albertaphil]

In the 654cc and 950cc models, ruggerini made 3000rpm and 3600rpm models. The model numbers were different but they were all the same parts in the parts book.

Yes, 3000rpm makes 50hz on a generator and 3600rpm makes 60hz.

28.5 horse power @3000rpm so at 3600rpm it has to be around 33 horse power. With a turbo that moves it up to around 4000 to 4200rpm and about 38 horse power.

Well I got that wrong, dur it's 25 horse power @3000rpm. If it will rev to 3600rpm it will only be 27 ish horse power, the key word is if. So that's only 4 ish horse power more than my RD211. This engine is low compression and glow plug, I don't think it is the same as a RD950, although a descendent of it.

Anyhow it turns out this is 37 kilos (that's 5stone 11 in English) heavier than my RD211, so it will drink the juice, not to mention the extra 4 horse power.

Bugger!

4 things:

1) Lombardini say no it will not rev to 3600 apparently it is a physical impossibility (so it probably can).
2) Conflicting information from Lombardini PDF docs (yes more conflicting info) one minute it's a 25 horse power another minute it's 28 horse power.
3) For anyone who reads all this waffle in the future (just for reference): When Sam said Ruggerini 950, I now think he meant Ruggerini RD211 (950cc). As I have found that a RD950 is a single cylinder. I didn't know what the Ruggerini version of the lombardini 9LD was (only ever seen one, on ebay) and took it as read it was 950. Confusion.................
4) How come this entry is already on the search engines and pages of my website still will not appear after friggin yonks!!! Aaaaggghhh!
