  1. The J60 may or may not have points, some Belgian machines have points. If The J60 has got an electronic ignition module then it will also have a rev limiter built into the module that can be disabled by pulling a fuse which will either be on a fuse holder incorporated into the ignition coil (British Machines) or if a Belgian machine on a fuse holder adjacent to the coil. The Rev counter is normally driven by a pickup mounted on the counter through which passes the ignition feed wire. The Rev counter was made by Smiths Industries and is now unobtainable, through age it loses accuracy and can also lose linearity. because of loss of magnetism and the hairsprings becoming weak, as well as friction through wear in the movement bearings. It maybe repairable, in the end I gave up with mine and fitted a VDO rev counter with a sensor off the fan, The VDO rev counter also has a hours run meter. The diesel model CVRT uses the same VDO rev counter using a Honeywell sensor mounted on the flywheel sensing the flywheel starter teeth. A suitable sensor pickup point on the petrol engine is also the flywheel starter teeth, were in not for inaccessibility a more ideal sensor pickup point would be the rear of the engine crank toothed belt drive which has less teeth per revolution. Anyone doing a conversion to a VDO stepping motor rev counter needs to consider the design of the sensor and it's maximum pulse output, since with too many teeth on the pickup point some sensors cannot cope with the frequency. Some sensors require power and others do not. The other considerations are the clearance between the sensor and the tooth or bolt head it senses as well as the cost of the sensor (The VDO magnetic sensor is astronomical in price) The VDO stepping motor rev counter is the most versatile of rev counters, will cope with most types of sensor and can be calibrated in situ.

  2. Television down lead is 75 Ohms and near enough to 80 Ohms that it can be used and you will see no difference whatsoever at the frequencies used by a WS19 Diana
  3. I am not a K60 expert - an interesting engine, with opposed pistons and a 2 stroke! I would take some compression readings since you have the injectors out and see what comes from that. My experience of 2 strokes is - UGH ! What I do remember though is a worn cylinder hard to start until warm. You do of course have the manual ? https://www.ebay.co.uk/itm/K60-Rolls-Royce-K60-Workshop-manual-Publication-No-2291/253378490234?hash=item3afe88ef7a:g:PwUAAOxyDLZR-97Y As it specifically mentions cold start! Diana
  4. Cylinder pressure based on the spray being more volatile than diesel therefore lower compression needed? Diana
  5. I leave a bolt out of the inspection plate below the gearbox oil drain, any water drains out, also goes to show if there's an oil leak. Do the same for the sump inspection cover.. Diana
  6. Has anyone noticed the adjusting screw with green paint has been adjusted, so that the paint seal is broken? Diana
  7. The answer is yes, if you have an appropriate plug for the RAK, and short circuit 2 pins of the vehicle socket to operate the relay that feeds the power to the food warmer.. It's a food warmer, not a boiler by the way. Diana
  8. Instructions for RAK 15/2 Please note the thermal fuse is 190 degrees C and NOT 175 degrees as stated in the British version of this manual, attached the USA version which also gives the part No of the thermal fuse and it's correct temperature. If the heater will not warm, check the thermal fuse located in the bottom of the food warmer. Diana RAK15 Service Manual.pdf
  9. I have two pieces of Dunlop Trakmark, as new 4ft x 4ft nominal size (actually a bit larger) and 2ft x 3ft, again nominal size. £30 plus carriage. Whilst the two pieces are new there is a self adhesive backing that will need to be removed as it has become ineffective with time, the Trakmark being NOS. The TrakMark itself is perfect condition and will be sent in a cardboard tube. Weight about 4.5Kg Diana
  10. An FV105 is a Sultan, an FV103 is a Spartan, the pictures appear to be that of a Sultan. It also appears to be a diesel Sultan, which has a slightly different Drivers Instrument Panel to that of a petrol Sultan, especially the tachometer.. Diana
  11. Um.. drill and tap steel armour? Unless you have a mag drill then its going to be more than difficult. Tig is the way to go.
  12. A firm tried it on my Ferret and they just wouldn't hold. In the end they tig welded them on without filler wire. Maybe the gun they used wasn't powerful enough? Diana
  13. A stud welding gun doesn't work but TIG does for the studs. Diana
  14. http://www.amateurtele.com/print.php?artikel=265 Use Google Translate. Racal (Kapsch) VRM 5080 Cheaper than a Clansman 353 - and no final tube (valve) Note does not fit the Clansman series radio mounts. Diana
  15. The switch is pneumatic. In the event that the oil fix doesn't work a new leather seal can be made from a disc of 1.2 mm thick leather, after drilling out the rivet in the centre of the piston and replacing with a small screw and nut. Nominally its a 10 second delay but that may not be on both right and left. - it's a bit of a hit/miss affair regarding timing. Diana
  16. http://www.totectyres.co.uk/Trucks.aspx Incidentally Totec will also supply the correct radial tyres for Ferret's etc - so they need not all end up with Bar Grips. and the correct tyre is not 8 ply either.. Diana
  17. In the Works bookshop yesterday - Haynes Owners Workshops manuals reduced from £22 to £6. I saw The Tiger, Sherman and Chieftain. There may have been others. Diana
  18. Liquid Paraffin is a mineral oil, not the best thing to put on rubber (depending on the rubber of course) The best safe thing for rubber is silicon oil/grease. Diana
  19. A CVR(T) fitted with a J60 engine, which is to all intents and purposes an E type engine/XJ6 engine, when fitted in a car has a 12V nominal 66AH battery. Therefore two 12 volt batteries in series @66AH is more than adequate (Cranking amps unknown), however 770A seems to be recommended @12V AGM cells info = https://nyln.org/agm-batteries-pros-and-cons-list Diana
