  1. And it's still going strong..... Thanks Richard.
  2. I am & you're correct. Put it down to it all being a little while ago!
  3. I recall the FD12 was selected for the Hunt class because it's characteristics of low vibration & low magnetic signature were necessary when sweeping above active mines. The FD12 generated electrical power at 1800 r/min, which equates to 360 firing cycles per second, vibration was further minimised by mounting the gen set on a raft with two sets of mounts transmitting little vibration to the hull/sea. Three gen sets were mounted in the hull above sea level further reducing noise transmitted into the water. The crankcase was cast in non-magnetic aluminium, as were many of the auxiliary cas
  4. For info, the Hunt class were built as MCMV (mine counter measures vessels), the propulsion engines - Deltics & the gen sets - Foden FD12 2-strokes were built to challenging low magnetic specs utilising stainless steel conrods, crankshafts & other components. In service they proved to be very expensive to maintain as a result of the exotic materials employed. The Hunt class strategic requirement is now a Mine hunter &/or Fishery protection vessels, which no longer require a very low magnetic build. In addition degauzing methods have improved, so all the original engines were repla
  5. Back in the '60's there was a Junkers wartime opposed piston aero engine in the K1 area of the R-R factory at Crewe, where the K60 was manufactured.
  6. Swiss application is more likely Swedish. R-R supplied circa 300 x K60 for the Swedish S tank....

    I quite agree this 'improvement' is retrograde. It is great shame. The old adage of if it ain't broke don't fix it applies here. Jerry
  8. Splendid vehicle Kevin we'll miss Queenie, I'm sure she'll sell in a trice. Best Jerry
  9. You're right Adrian, there goes another senior moment... The toolbox looks & fitted great - thanks. Best. Jerry
  10. Mike & Sam - many thanks for the useful tips. Best. Jerry
  11. Mike We've got the manuals, which we've read. Thanks for the re assurance that it's as straight forward as it says. No tricks or nasties. You know what we're going to be doing tomorrow... Thanks again - Jerry
  12. Can some kind person tell me how the 'Lite' clutch is adjusted? It appears to have a bl..dy great central coned coil spring providing the engagement and a sort of lever plate within to disengage the friction plate. There are adjustment shims to increase the spring tension and the clutch pedal linkage needs careful adjustment. Any advise in getting the best from this set up will be gratefully appreciated as the clutch is starting to slip. Thanks Jerry
  13. Many thanks Ian & Runflat. I'll be following up your recommendations. Best. Jerry
  14. The speedo cable has just failed on my C4, the inner cable failed at the speedo head as the chronometric speedo failed on the way home from an event on Thursday. Thankfully the inner cable can be removed easily. Does anyone have a spare cable or any advise on a source for a replacement. Jerry
