Fuego Turbo / gordini CAM FOLLOWERS URGENT

Is that off the seat timing Alan?

Well, I got this good news from Dema Elgin, one of the top in his field in the US:

The good news is that every one of your lifters was above 65Rc!!!! We reground them all today and can ship them back to you via UPS.

I had to do a Wiki lookup to find out what a 65 Rockwell score is:


Typical values
Very hard steel (e.g. chisels, quality knife blades): HRC 55–66
(Hardened High Speed Carbon and Tool Steels such as M2, W2, O1, and D2, as well as many of the newer powder metallurgy Stainless Steels such as S30V, 154CM, CPM-M4, ZDP-189, etc. )[12]

Axes: about HRC 45-55

Brass: HRB 55 (Low brass, UNS C24000, H01 Temper) to HRB 93 (Cartridge Brass, UNS C26000 (260 Brass), H10 Temper)[13]

I will still let the list members know how my search for new ones turn out; so far GBS has two. Colombo none (sounds like a sports score).

what is "gob-smacked"?

Smacked in the face (Gob-smacked) = Amazed

Is that off the seat timing Alan?

Yes, seat to seat. The 12G cams were quite long duration, more like 40/72 but lift is not high.

Even the full competition cams Renault used in the A110 1600 (usually 1800) only had 400 thou lift at the valve, but did lift and close the valves quite quickly and had a large plateau on the top of the lobe.

Hello,

here is the response, or not, from the suggested vendors in my search for new tappets/cam followers/lifters for my 843 engine::

did not reply:

replied, but none available:
http://www.colombo-france.fr/
http://www.simon-auto.de/

has two new lifters available:

all of those who replied did so promptly

the good news is what I recorded in an earlier post, which is that all 16 lifters I sent to Elgin Cams in California tested 65, very high on the Rockwell hardness chart, and were reground by owner Dema Elgin at a cost of only $16.50 USD each, including testing the hardness of each lifter. And Elgin did them within one day of recept.

thanks to all list members who helped in the search. There really does seem to be a worldwide scarcity of new lifters, but regrinding the old ones seems to be a viable option.

Regards,
