camshaft sprocket nut torque ?

so i have the new timing chain on with the camshaft sprocket sitting back, snug on its woodruff key and the intermediate gear mated correctly with 10 roller set up and timing pinion dot sat between the marked tooth - all good. A few things surprised me tho - both the timing pinion nut and the camshaft sprocket nut came off very easy - couldn't have been more than 20Nm. Happy fastening the worm nut back on at 20Nm but not so sure about the camshaft sprocket nut now. Having trawled the net i had figured maybe 40Nm as a compromise but seems to depend on the camshaft spec ?? So is there a definitive torque value for the camshaft nut on the 1973 Mk V roadster (post combat 750) ? Also, the oil pump studs came away with a wavy washer each but i dont see these washers in the parts book - these be replaced with a bit blue locktite instead of the washers ? And finally . . anything i should look out for when turning over by hand and prior to firing up / strobing the boyer ? sheez long post

I can not find any torque value listed in manual either just a note to tighten *sufficiently* W/O shocking nut or using long breaker bars, ONLY by slow even force WITH pinion shaft back up protection by a cut in half TS cover of special DIY brace/bracket. Going by you finding it on loose side and my own meager experience I say aim for over 35 lbft. I and my buddy have put cam nuts on a number of times w/o the pinon protector - so luck of the draw if pinion shaft is seated enough to take this or not. It is the Only place I use loctite on engine fasteners anymore so use slight over torque above manual values as after several engine openings found loctite not locking anymore any where else. Experts race and hi end builders have also settled on 10 lbft more on major engine fastens than what work book lists. I have cut off cover not going to need for a season or so so could send to use for just the postage. Might heat the nut good to help get it snug enough and heat again to remover later for loctite release.

Old Britts says,
•Camshaft sprocket nut (06-7774) 60 to 80 ft lb depending on cam metal.
•PW3 Camshaft sprocket nut (cast iron) 15 ft lb.

thanks hobot - i think i'll aim for about 30 maybe 35 lb ft (40 - 47ish Nm euro money) Sounds about right and with the support plate on as you say should be safe. I'm pretty sure it'll not be the Peter Williams PW3 racing camshaft in my stock 750 but at the other end of the scale 60 - 80 (!) lb ft sounds like an awfy lot of beef on that thin nut ?

Yes about as tight as can stand to crank on cam nut with normal 3/8s drive rachet without a breaker bar does it for me and my buddy Wes long term. Definitely under 50 lbft and am shocked that some cam nuts could even put 80 lbft on it w/o injury. I have done up 6 cam nuts but first 4xs did not have the back up support so can not be that risky in most pinon cases. Cdos are Crazy making mechanical contraption to me and most pensive time is when me and my double checking buddy can not come up with another good reason not to try to start. What I have a hard time getting tight enough is the DS crank and clutch nuts, both of which I had come off more than once a few miles after first ride from home, so I am not as brave as I sound on over torque but forced a bit beyond what I think is good enough - too many times.
