camshaft nut
Me again.
I need to buy a socket to tighten this nut. Just want to know the correct size to buy 36mm? 1 7/16 ? Thanks as always. |

It is imperial so 1 7/16". I did think 36mm fitted though but maybe not.

Thanks, Burdekin ! Just to confirm,
Imperial 1 7/16, yes ? Sorry to be pathetic. Looks 1 13/32 on tape measure! Last edited by sleek lemur; Jan 25th, 2021 at 13:35. |

The whole thread that contains my comment above is worth a read through as it contains info about the correct torque for the cam nut. Don't use the high figure in Haynes and the old Volvo manuals.

Thanks, Derek. Very useful thread. I have followed Amazon Cars' B18 assembly video for my installation.
"If the garage doing the job doesn't have a good understanding of the B18 then they need to know at TDC No1 on compression stroke the pips on the gears are not together but 180 degrees apart." This is clearly very important and I nearly had a heart attack when I read it just now as had not considered it. However, I then realised that I am rebuilding the block without the head on ! So, the valves will set themselves to the correct position when I attach the head, yes ? I understand that I have to adjust the position of the gears when I am inserting the distributor drive. Heating gears before attempting fitting worked well. Larger cam gear was a bit stiff and I did use the nut to push it on, however thankfully it slipped on without much force and is now flush with the smaller gear. I can't torque it down until the 1 7/16 socket I've bought arrives. |

General information about "is it this - is it that"...
...for six sided / hex nuts and bolt heads look for the many (now widely available) sockets that are dsigned to grip on the flats of the head / nut. [Cue wavy image of going back in time with wavy harp music] Back in the day some time in the 1990s I first noticed adverts in classic car magazines for these types of sockets (and spanners) from a company called Metrinch https://metrinch.com/metrinch_en Since then the idea has been adopted by many other manufacturers - even people like BGS do them. I realise this is "yet another tool" to spend money on instead of car parts but if you buy as you go / can afford to buy as you go these "multi-size" solutions do work out to be really useful. The main thing is that whilst the nearest "imperial" or "metric" size often will do - especially for the larger sizes - the versions that grip the flats are less likely to cause any damage if you need to apply forces inexcess of five white knuckles. [Disclaimer - smaller sizes of these grip on the flats sockets (say smaller than 10mm) tend not to be as versatile as the larger sizes - but - as you are not likely to be using the white knuckle scale of applyiong torque other "almost the same" sockets tend to work just fine especially on really obsqure old english stuff]

Found a 1 7/16 socket at Zoro tools for £7.69, hurrah!, but the issue is that sockets this size all seem to be ¾inch drive, so had to but adaptor for £19.99 boo!
