Hi all, I'm looking at getting the correct whitworth socket for the axles of my 109 (the 6 little bolts that hold the axle in). Does anyone know the size and where I can find it? I used a 15mm and it kinda messed up the bolts (ordered new ones though). Thanks Max T. P.S. Any other info on Whitworth is welcomed as well | ||

LOL. Whatever happened to: "from what I've found, the earlier series trucks (like 74' and older) are standard with a little bit of metric here and there. I've got a 73' and my entire tool set is geared for standard. Every once and a while I need metric and I do carry some metric." Anyway, Snap-on makes a small selection of British Standard wrenches: http://buy1.snapon.com/catalog/pro_det.asp?P65=yes&tool=all&item_ID=5336&group_I D=567&store=snapon-store&dir=catalog and sockets: http://buy1.snapon.com/catalog/pro.asp?tool=all&Group_ID=482&Group_Name=British+ Standard%2C+Shallow%2C+chrome&Sub_Cat_ID=1913694&Sub_Cat_Name=Sockets+%2F+Specia l+Purpose&Cat_ID=1913211&Cat_NAME=3%2F8%22+Drive&store=snapon-store Note the "Not Flank Drive" warning on the sockets, if this even matters to you. One guy I know with a Series bought a Metrinch set. I think this was actually a pretty good decision on his part. The main disadvantage of Metrinch is that it won't work in tight spaces because of the slop between the tool and the fastener. But if tight spaces are not a concern, the Metrinch might not be a bad choice. | ||

John, I've worked mainly on the engine, body panels, and electrics on my 109 so far and FWIW these are the only areas that concern me (as they are the only parts that break down). Now I went to install a locker in my rear axle and I just so happened to have found a random bolt that was Whitworth. Its just the bolts that hold on the axle shaft. This is the first nut I've discovered that was not neither Standard nor Metric. Since my entire tool set is geared for standard with a little bit of metric, this is quite a shock  . Its kinda like the Rover V8 engines, its all metric until you get down to the cylinder heads. Why? I don't know. Quick question: what does "Not Flank Drive" mean? I don't know what it means so I don't know if it applies to me. Max T. | ||

Max: try these sources: from friends who dabble in british motorcycles, the King Dick line of tools are some of the better ones. http://www.mototools.com/Whitworth.htm http://www.britishtool.com/ John: whatever happened to that one guy in Big Bear who won a set of Snap-On (he said) whitworth wrenches in the raffle? He was running around trying to trade for something else. DW | ||

"Flank Drive" is Snap-on's trademark term for the way many of its sockets and wrenches are shaped. For example, a six-point Flank Drive socket is not shaped like a perfect hexagon. And a 12-point Flank Drive socket is not shaped like two concentric hexagons. Instead, Flank Drive sockets have recesses at the points and subtle curves on the flats so as to drive a fastener on the flats rather than the points. Driving a fastener on the points will round the fastener because the points are the weakest portion of the fastener. Here's a pic of a 12-point socket and a six-point socket, both Flank Drive: http://www.expeditionexchange.com/snap-on/DSC05896.jpg Here's another pic of a six-point Flank Drive socket: http://www.expeditionexchange.com/snap-on/DSC05653.jpg You can see that recess in the bottom of the socket. That recess is perfectly round and gives a good contrast with the Flank Drive profile of the driving portion of the socket. You can see how the tips of the socket are recessed so that the tips of the driven fastener will not be touched or pressed against (and rounded under heavy load). You can also see how the "flats" of the socket are not flat at all but rather are curved slightly. When these "flats" drive the fastener, they drive the fastener on the fastener's flats. The fastener's points are not touched and not rounded, even when the socket expands under heavy load. Here's a pic of an eight-point Flank Drive socket: http://www.expeditionexchange.com/snap-on/DSC06473.jpg Again, the points are recessed and the "flats" are radiused in a very studied and calculated manner so that the socket will drive the fastener on the flats rather than the points. Using a properly fitting Flank Drive socket will go a long way toward preventing the rounding or mangling of fasteners, whether you're using manual ratchets or an impact wrench. The difference is there. The Flank Drive concept is similar to the Metrinch concept, except a Flank Drive socket fits just as tightly or even more tightly than a standard socket. Thus it is very well suited for use in tight spots. The Flank Drive principle is also suitable for use on six-point, eight-point, 12-point, five-point, spline, etc. The principle is even suitable for use on open-ended wrenches, i.e., "Flank Drive Plus". "Flank Drive Plus" is different from "Flank Drive" and refers to the Flank Drive principle strictly on open-ended wrenches. The jaws on the open end of Flank Drive Plus Wrenches are not parallel. Rather, they have a distinct shape like so: http://www.expeditionexchange.com/snap-on/DSC05772.jpg This shape is designed with different serrations, curves, and recesses so as to grip a hexagonal fastener better and drive it on its flats rather than its points. There was a long discussion about Flank Drive Plus wrenches in this thread: ../17/28993.html> If you do a BBS search for "Flank Drive", you'll get lots of hits. | ||

"whatever happened to that one guy in Big Bear who won a set of Snap-On (he said) whitworth wrenches in the raffle? He was running around trying to trade for something else." Snap-on tools in the Rover Rendezvous raffle? I think that guy hit his head. | ||

Thanks John for the explanation of flank drive. I don't need anything that fancy, but it is a very nice design. Max T. | ||

I bought a King Dick Whitworth socket set from Rovers North a few months ago. Not sure why, seemed like a good idea at the time  SC |
