SI units were introduced in 1960. You have had 52 years to get used to them. :mrgreen:

Whats's wrong with using a 9.81 correction factor between kg and Newtons? :mrgreen:

0.454 kg in a lb
0.3048 feet in a metre

Easy peesy...or just look at the other scale, of course ;) I'd say GW owe you a set of main bearing bolts though :w

When I was at Sperry Univac. My mate Keith and I re-invented the world of measurements by changing the derived units for a new system based on a different base. So instead of the Metre, Kilogram & Second (MKS) ours were the FFF system where the basic units were the Furlong, Furkin & Fortnight. :mrgreen:

Now a fortnight is quite a long time in anybodies money, especially so when we were dealing with computer hardware. So we decided a practical day to day unit of time was to be the femptofortnight (10^-15 of an F) this evaluates to 1.2nS so quite useful really :D

We also came up with a unit of currency bigger than a penny so more useful. It was the nanofax. 10^-9 of the reserves of the Halifax Building Society. - about thruppence.

Yes, that's how I'd read it - the red figures are Cologne.

However........ that's not all. I don't have any direct experience of the cologne, but I do have the Cologne Supplement in my collection, so I had a look in there. The figure given for the mains is indeed 90 - 104 as listed, *but* the Cologne engine figures in the supplement are given in Newton/metres not foot/pounds and if the online converter is right, 90 - 104 Nm equals 66.4 - 76.7 lbs/ft :(
Looking at a few other figures, I think that may be true for all the engine figures?
Wow - that useful torque settings is a straight copy from the GW parts list which makes it around 20 years old - and no-one's ever noticed!!

I'll rewrite it now Roger.

Sperry Univac obviously didn't keep you fully occupied then :mrgreen:

Checked out the Chevete manual for the torque figures for brake calliper to steering arm stub axle when I was putting the callipers back on my Sabre. Wow! 70 lbft or 100NM I don't believe it! On checking my original Reliant 6a factory workshop manual for the same dimension bolts it was 50 lbft Whew nearly got me that time Gremlins!

Aren't the Chevette ones 12.9 spec, so presumably have a higher torque figure?

Even though the caliper and upright aren't from a Chevette, I think I use 70lbft on the small sports?

The SS1 uses the same bearing for the back and front of the car so I think it is at fair assumption that the torque is the same. 203/244 stated in the manual for the back axle, is ok for the front.

Sorry but that's not correct Bill. They're totally different bearings front & back.
