Adjustable valve clearance 2-cylinder diesel engine - Lombordini

Question

Hello I have to adjust valve clearance in the Lambordini engine. I have manual service for this unit. Generally everything is given what and how but I have some questions. Which cylinder is marked first on the signs? The first one will be the timing? How can I set the camshaft on the basis of...

The manual is written to set any chosen cylinder in gmp. You will know which one, because - as you mentioned - the cams of the cylinder of this cylinder will be in such a position that no valve above it will open. Adjust the play, rotate the crankshaft 180 ° and adjust the play on the second cylinder. The clearance value is the same for both valves.

The order can be. 0.05mm probably will not make a big difference. If the motor is heavily loaded, give a little more clearance.

Orochimaru · Accepted Answer

Yes. It may not fire the first time until it pushes the fuel through the injections.

Thank you for your help. Tell me whether the order in which the valve cover bolts are tightened, shown in the drawing in the appendix, will be appropriate? There is no order anywhere, I know that you have to tighten from the inside and then cross. Regarding the valve clearance, the specification gives 0.20 mm and on the motor sticker I have given 0.15 mm what to take into account?

Please correct the title of the topic, these engines are Lombardini, not Lambordini.

And if I need to decorate the fuel rail visible on the first picture added (screwed on 4 screws) Should I pay attention to something during the assembly / disassembly, if I take off the cover, I tighten it properly and all this? I know that you need to replace 4 rings when you put it on, and I will. I have to take it off because I will replace the seal at the entrance of this rail. Is it possible to turn it all on the eye or rather it would be worth to buy a torque wrench to be sure that nothing will sweat, etc. I know where this difference in terms of valve clearance Lombordini gives 0.15mm but this engine is used in a quad and the manufacturer gives a clearance of 0.20 due to heavy engine loads.

Orochimaru · Answer

If you do not have a torque wrench, you can easily take it easy. Just try to make them all tightened with more or less the same strength. You can spin on a few times: first all with a screwdriver, then lightly with a wrench, then a bit harder with the key and so, until you feel that for this size of screws enough

Probably you will tighten it more tightly than you need (usually it tightens before you buy a key).

I also screw the fuel rail normally on new O-rings, then with a manual pump, pump the fuel out of the system and all this way?

Good morning ,
Does anyone have a schematic of this engine because I am looking for glow plugs for replacement? (Lombordini 502 Focs disel grecav)
Can someone help me where the candles are, are there two or more?
Please, send an email to adamglo(_at_)tlen.pl?
Regards and I will be very grateful

sebastian1260 · Answer

Ask the Lombardini service for a catalog of parts for your engine. They easily emailed such a catalog to LDW 702. In LDW 702, glow plugs are located under the intake manifold at 502 probably the same.

Hello, I have a question about these engines whether the injection pump fits from one model to another

wita5742 · Answer

And I have a question: how to set up the pump injection well? Because the cold one will start, and the warm one needs to be turned on for a long time.
