Is it possible to measure cranking rpm on a Series 3 diesel, and if so how?

Thanks

Yes, this kind of thing, and all you need is a small piece of reflective tape for the tachos laser to see.

That looks the exact one I got, useful for setting idle speed too, comes with sticky labels to put on crank pulley

This is very useful. I suppose I can use it most easily on the belt pulley which I have already marked with a white dot for timing.

I use my ear. If it sounds a bit fast I turn it down a bit and if it struggles to idle I turn it up.

Thanks. I do the same but I wondered how to measure the rpm at cranking speed. I had some information about this from another member.
