Whitworth and BSF use the same tools (sockets and spanners),so if the nuts and bolts are BSF then whitworth spanners would be exactly right. BSF or British standard fine is in reality a version of BSW (British standard whitworth) with more threads per inch (TPI).. If however,the nuts and bolts...

Thanks for the advice. I've been asked to supply a prop shaft tool but the buyer insists the nuts/bolts are 5/16 whit (Possibly why he came to us as we specialise in Whit and BSF tools) From memory I though even on the early Land Rovers they were 9/16 AF. I can source long waisted sockets in...

Does anyone know if the earliest land rovers used whit nuts and bolts on the propshaft?. I'm told it is a 5/16 whit but need confirmation if possible before sending the tool off to Aus.

I've still got imperial tools that I use myself dating way back to my apprenticeship. Looking at them now its a bit sobering,all those years that have passed and all those firms that used to make the tools that are now just memories. A few still exist but they now (apart from one) just...

Land rover traditionally hang on to 'obsolete' fixings. You can still find whitworth stuff on older models long after everyone else had stopped using it and the same with Imperial AF.

I'd have thought that mpg was about right. I run a P5b,pretty much the same engine and weight but maybe a bit more aerodynamic and without the drag of the four wheel drive set up. it does around 17mpg with 20 on a gentle run.

18mm is virtually the same as 5/8 whitworth. In fact some sockets come marked 5/8 whit / 18mm. There are two whit sizes that have almost direct mm replacements 28mm being the other. Have a look at the conversion charts here

AF means across flats,so a 1/2 inch AF spanner is half inch across (open ended) for whitworth a 1/4 inch fits a bolt which has a 1/4 dia whitworth thread (same reasoning for BSF . There are two standards of whitworth as at the start of the second world war the bolt head sizes were dropped down...

and a useless one.

Other than adding two stroke oil to get over the lack of lubrication of modern diesel I've not found many additives that make any real difference. Best of luck.

There is a conversion chart etc for whitworth,AF,BA and metric bolt and spanner sizing Imperial to metric socket and spanner size comparison charts.

Sorry,I didn't make things clear. This is a conversion on a spring set uo on a old Rover car,the mounts go in between the spring and the chassis. This is a conversion that was marketed some years back using mountings supposedly Land Rover gearbox ones.

Hi James thanks for the answer,I bought some of those but the thickness is 37mm (seems a fairly common dimension on them) and thats just too thick to fit. They really need to be 32mm or under.

I know this is joining in the discussion late but.......... I'm working on a project that uses what are supposed to be land rover gearbox mounts. They are approx 75mm in dia and just under 32mm in thickness,if anything they are slightly too large.The mounts are the old cotton reel type. All the...

Yes,more than the ones here.
