  1. In which case a minimum of 7/16 engagement in the bush. MINIMUM
  2. I'm assuming that this is a through bolt with a nut on it (as it is on my car)? If so and if the bolt is protruding through the nut then you have no problem. (Or have I misunderstood?)
  3. As a French resident (which I no longer am) if I wanted to tow my Brian james sprint shuttle with a French registered car I needed a carte gris(logbook) for the trailer because it was over a certain capacity (can't remember the exact figure). If I towed it with an English registered car that no longer applied
  4. This from the caravan Club: (dont know why the font colour changes ....) Trailer Tyre Pressure One of the most important safety aspects of towing is having the correct tyres fitted on your caravan and just as important having the tyres inflated to the correct pressure. The simple fact is caravan tyres often get overlooked and are not checked regularly. On your tow vehicle, there is usually a sticker conveniently located in the door frame or fuel filler cap reminding you of the correct tyre pressure. Unfortunately this is not always the case with all caravans. Your Caravan Handbook usually quotes the tyre pressure for the original tyre size fitted and the caravan loaded to the MTPLM (Maximum Technical Permitted Laden Mass). As the load in your caravan can change or on older caravans, the tyre size might have changed it’s worth knowing how to calculate the correct pressure from the markings on the tyres fitted to your caravan. You first need to be able to decipher the code on the tyre wall… this is a typical code: 205 / 65 R 15 94 H The first part of the number is the tread width, in this case 205 mm wide. The second number is the Aspect Ratio which means in this case the tyre wall height is 65% of the width of the tread. The next letter “R” is the construction, in this case Radial, the following number “15” is the rim diameter (in inches). The next number “94” is the load rating – more of this in a moment and finally the last letter “H” is the speed rating for the tyre. Load Rating The load rating for the tyre can range from 60 to 130 which equates to a maximum load per tyre of between 250 Kgs to 1900 Kgs. The first thing to check is the tyres are rated for the MTPLM of your caravan, so we need to know the load index ratings. From the table above, you will be able to cross reference the load rating code number to the actual maximum permissible load the tyre is rated for. So in our tyre data example from above, we can see that a load index of “94” means the maximum load for the tyre is 670 Kg’s. Remember that is the load for ONE TYRE… so on a single axle those two tyres could carry a maximum load of 1340 Kg’s. The recommendation from the tyre industry though is you should never exceed 90% of the tyre’s load index, so in this case the maximum axle weight would be 1251 Kg’s The other bit of information we need to know from the tyre is the Maximum Tyre Inflation Pressure and Load. This is usually located on the side wall below the tyre data in smaller text. It will say something like “MAXIMUM LOAD 720 Kg’s MAXIMUM PRESSURE 52 PSI” it might have the pressure given in Bar. Once you have the MTPLM of your caravan and the maximum pressure for your tyre we can now work out the correct tyre pressure. Take the figure for the maximum pressure for the tyre and divide it by the maximum weight from the table above. Now multiply this figure by the actual load you are going to put on the tyre – so half the MTPLM for a single axle caravan or a quarter of the MTPLM for a twin axle caravan. The resulting figure should be the correct inflation pressure for each tyre. Lets look at an example for a single axle caravan: Tyre Details: 205 / 65 R 15 94 H – Maximum Inflation Pressure 60 PSI Weight of caravan: 1200 Kg’s 60 / 670 = 0.08955 (Max Pressure for tyre divided by load rating) 0.08955 x (1200 / 2) = 53.7 PSI (inflation factor times half the weight of the caravan) So the correct tyre pressure is 54 PSI Working out for a twin axle caravan: Tyre Details: 205 / 65 R 15 94 H – Maximum Inflation Pressure 60 PSI Weight of caravan: 1800 Kg’s 60 / 670 = 0.08955 (Max Pressure for tyre divided by load rating) 0.08955 x (1800 / 4) = 40.29 PSI (inflation factor times one-quarter of the weight of the caravan) So the correct tyre pressure is 41 PSI Top Tip: As a rule of thumb, the inflation pressure of a hot tyre is usually about 4 PSI higher than when cold. If you check your tyre pressures when hot and it is more than 4 PSI higher, then the cold inflation pressure was too low. If the hot inflation pressure is less than 4 PSI difference than the cold pressure, then the cold pressure was too high. This is derived from: “For every 10 Deg F temp change the tyre pressure changes by 1 PSI”
  5. I assume you're talking about a Ford three rail gearbox? googling Ford three rail gearbox shows good stuff including images
  6. On my 1990 car the reservoir is integral with the cylinder. Is your reservoir separate? id speak to Redline...
  7. Can you put a jubilee clip behind it?

    New clutch time

    Once you have removed all the bell housing bolts and freed the engine from the chassis, if you depress the clutch pedal that usually frees the engine from the box... try it next time ....
  9. My (frequent) experience is that the third gear synchro ring breaks but stays in place. This makes selecting third gear difficult. After a while the synchro ring becomes dislodged and then you either can't get it into gear or it gets stuck In third. In any event, it's box out and a rebuild I'm afraid. I broke a few rings (track use) and it's the reason that I run a dog box now (no synchro rings)
  10. Looks like quite a bargain to me. The Dunlop version sells for a lot more
  11. Removal is more tedious than difficult. Unpick vecta loom and trace wires. Almost all will not be connected to anything. The few that are connected to original wiring should then be reconnected to the appropriately coloured wire in the car loom
  12. Any immobiliser system has the possibility to immobilise you and it will be in the most inconvenient location and time when it does. I was on the other side of the channel on my way to a pre booked ferry. Removal is a good idea
  13. The friction plate? if so, no problem

    Sigma warning

    If the core plugs are in the coolant jacket they should always be submerged. The coolant jacket should have no air in it. Has trapped air accelerated your problem or is it just poor quality parts?
  15. Yep, I think I remember that Charles....Slovakiaring. Good job that the pipe work running across the ceiling of the pit box was strong .....
  16. Yes you need a quick release boss and a different upper steering column
  17. Unless you have a multiplate clutch, you don't need a splined tool. The standard tools will work fine
  18. ECR

    Radius arms

    Yes, but moving house back to uk so no chance of finding them ...
  19. An old first motion shaft is essential if you have a twin plate clutch. The standard aftermarket offerings can't synchronise the splines in the two plates
  20. Airlock looks probable but for peace of mind i'd replace the cap (theyre not expensive) O/E Rover part number: PCD100160 Halfords HRC606 0.8 to 1.2bar opening pressure. I have the 2ltr engine which always sprayed coolant when used hard on track. Fitting a swirlpot into the system cured that.. No sign that I can seeof oil in the coolant so a head gasket problem looks unlikely
  21. A mount for the rear exhaust box when fitted (if I understand your photo....)
  22. ECR

    Cracked Shock

    Assuming the replacement sleeve is identical to the cracked one, remember to take measurements before removing the defective part...
  23. So kind of you Andrew. Top marks!
