    Do we know if any of the regular contributors are involved with the Tooling Fund Ltd company? If I don't get any responses I will email the address in the mag and see how I get on. I am also keen to get some decent axle stubs made as well.

      Paul Smith is the chairman according to the Mag, email soctflATstag.org.uk.

      Decent stub axles (for the front at least) are already available - got mine from Chris Witor, fitted perfectly, checked the tapers out with blue - perfect.

          Wilf,

          I did chat with Chris about the source of his axle stubs and I seem to remember them being the same as the other suppliers, i.e. there is only one source for use with the original hubs. It's not a huge market. You can get uprated axles for the new uprated hubs and these do not have the wasting in the mounting taper and are presumably the correct taper angle also. I think most people have had to grind their axles in because the inner ends (small diameter) are slightly too large in diameter. I have checked new axles with new vertical links and you can rock sideways by a few thou at the fat end before grinding them down. That's why they snap off IMHO. It would be great to see the original drawings as this would prove what part is wrong (link or axle). The original Leyland axles have the same issue also.

          Not sure if blue would show the problem unless you keep the axle perfectly centred. It is easier to see without blue. The inner end gets more polished than the outer when the axle shaft is rotated in the link in a lathe.

          Drew,

          Thanks for that. If there is no response from a member of SOCTFL, I will pm him and see what he thinks.

            I doubt that SOCTFL will get involved with stub axles as there are good ones readily available from several suppliers already. I changed mine out last year for ones supplied by Chris Witor and they have now done over 3,000 miles.

            Maybe any issues you have with available units could be fed back to the suppliers for product improvement.

              Dave, I don't think they fail until quite a high mileage. I think you are probably safe for more than100K or so whatever you have fitted. Mine snapped at around160K and was the original axle. They do say the newer ones are safer because they are machined from better stock. It is just so serious when it does go that I do feel it would be worth sorting.

              Many have recommend fitting the uprated axles and hubs for safety and handling (they don't flex as much). Why have we got uprated axles/hubs if the original design is fine?

                Because the aftermarket is always inventing something "better"?

                  That is also true!

                    And in truth, the original designs have lasted nearly half a century, probably multiples of their design life.

                      Basically the chain snapping without warning is unusual, somewhere between 2/3 and 3/4 of breakages (depending whether you include the Dolomite or not) were caused by the jackshaft seizing first. A good quality chain may even shear the jackshaft dowel without breaking the chain and cause much less damage. The only certainty is that cheaper chains will stretch and cause even faster wear on the butter soft crank sprockets that are available these days.
                      All that metal that is lost from the sprockets has to go somewhere. It isn't all caught by the filter as some goes through the bypass valve which is why I now favour magnetic sump plugs.

                      do you know what causes the jackshaft to seize?

                          Dave,

                          I think all the suppliers supply the same part from the same ultimate source which have the wrong taper angle. I did ask Chris if his source was different and he thought not.

                            Regarding the front stub axles, CDD machine their own, and supply them with Timken bearings, which are probably the best generally available. I have them on my Stag, and they are superb, greatly reducing disc pad knock-out on winding roads.

                              Quite a few things… too much oil pressure.
                              No oil pressure.
                              Chains too tight.
                              water pump ~too much torque to turn.
                              hydrodynamic (block or shaft) bearing worn out.
                              & other things….
                              There are 2 secrets to staying on top :- 1. Don't give everything away.
                              2.

                                Dave, Do CDD do their own stubs that fit the original hubs? I know CDD do "uprated" axles stubs to go with their own "uprated" hubs. Those stubs, commendably, do not have the narrowed section which contributes to the axle flexing/snapping. But you are into much greater cost in that case. All the axles stubs that mate with original hubs, that I have seen, are the same design and seem to be from the same source.
