shopnut Posted March 20, 2007 Share Posted March 20, 2007 Any one out there know the front hub nut size across the flats?, ie. the rear hub nut is 70mm or 2 3/4". Would also be interested if anyone had the original box spanners. Thanks Quote Link to comment Share on other sites More sharing options...
R Cubed Posted March 20, 2007 Share Posted March 20, 2007 The front wheel square nuts accross the flats I think are about 1 1/4" will check tomorrow and let you know for sure, far tooo cold to go out there now. R Cubed Quote Link to comment Share on other sites More sharing options...
R Cubed Posted March 27, 2007 Share Posted March 27, 2007 The square nuts are 20mm across the flats mught need something a little bigger to fit. Quote Link to comment Share on other sites More sharing options...
shopnut Posted March 27, 2007 Author Share Posted March 27, 2007 Hi Thanks for your reply, but I have realised the measurement you have taken was of the the wheel nut bolt, square end, I was, and still am, trying to find the hub nut size, this nut secures hub to stub axle.

R Cubed Posted March 28, 2007 Share Posted March 28, 2007 Dur I must be dum, yes, I now see what you are on about. I am in the processes of doing king pin bearings on my 352 so I could wip off the drive flange at the weekend and measure it for you !!!!!!

shopnut Posted March 28, 2007 Author Share Posted March 28, 2007 I am hoping it will be 65mm, as this is the size opposite end of the 70mm box spanner just purchased. Thanks for you help with this. Shopnut Quote Link to comment Share on other sites More sharing options...
R Cubed Posted April 1, 2007 Share Posted April 1, 2007 Right then, main centre hub nuts, the ones which holds all the wheel bearings on and also the lock nut which are under the hub drive flange are 83 mm across flats going by my vernier, sorry to be the bringer of bad news but reacon its the next box spanner up from the one you have :-D R Cubed Quote Link to comment Share on other sites More sharing options...

Shopnut Shopnut, Don't forget that metric sizes were not used on these vehicles, any metric spanner is likely to be either sloppy or not fit. R Cubed has replied saying he measured the nut with his vernier and it is 83mm, this would work out at 3 1/4 inches. Hub nut box spanners are still available in inch sizes from motor factors who deal with commercial vehicles. Richard Quote Link to comment Share on other sites More sharing options...
R Cubed Posted April 1, 2007 Share Posted April 1, 2007 An interesting point, you say about it not being metric so what sizes did they use, I have found metric to be a better fit on some bits. If not metric why was the Howitzers barrel 105mm !!!!!!!!!! Not being awkward but am very interested in the correct nuts and bolts that would have been used when building these sorts of trucks ??

R Cubed R Cubed, Vehicles made in the USA during WW2 and right up to around the 1980's, would certainly be using inch sizes, their threads being predominantly American National Course and American National Fine. Spanner sizes will be AF, which means "Across Flats", so to determine a size of spanner / socket required, measure from flat to flat, with an Imperial vernier or caliper to save having to convert. Do not fall into the trap of what some people do, when measuring a bolt head, for instance, 9/16"AF spanner size, they then think it is a 9/16" bolt, the actual shank diameter would be 3/8". Forget the 105mm gun, armaments are a rule to themselves, but I have no doubt that the gun carriage would use American inch threads on it.

Degsy Posted April 2, 2007 Share Posted April 2, 2007 Many CCKW's were rebuilt by the French Army and metric sizes were used on some items, possibly other European armies may have also done this. Quote Link to comment Share on other sites More sharing options...
R Cubed Posted April 2, 2007 Share Posted April 2, 2007 Aghhhhhhhhhhhhhhhhhhhhhhhhh Inches and mm Aghhhhhhhhh which is which ;-) !!!!!!!!!!!!!! ;-) Ok so it all should be in inches, thats great, am aware about AF being across flats and also that the head does not relate to the bolt diameter, thanks for making the mud a bit clearer.
