Hello I have just replaced the drive belt on the distributors on my 1990 Spur 11. What a PITA!!!! Also replaced the 3 bearings as one had started to seize and spin in the housing! Fitted new SKF bearings and a new belt Virtually a full days work for me. Why not just a single distributor as on my Silver Cloud? Have Fun Trevor Pickering |

I asked that same question, as well as can I replace the dual dizzy with an older model. Consensus was "just leave the original one in place". That belt was designed to keep the service dept. making money. |

Hi Trevor, Two Dizzies = get you home. I had a problem with our Mulsanne S a few years ago - would run on 4 then 8 then 4 cyls as it felt fit. On a dual carriage way at 70 mph it ran OK (most of the time) (0 to 30mph in 3 days on 4 cyls then it would fire on 8 - oops there's a car in front - entertaining). Road junctions were exciting as well. One of the ignition amplifiers was faulty. Single coil / dizzy - stranded. Two coils / dizzies = got us home (200 miles) Worth a bit of hassle when changing the belt every 30,000 miles me thinks but then I didn’t have the hassle you had. Regards Darryl |

Thanks Darryl Yes I am pleased I will not have to do this job again for quite a while and as you say its handy to have a "get you home" back up. I am just about to start replacing all the steel fuel line with copper which should be fun!!! regards Trevor |

The drive belt was originally meant to be a "for life item" till they started to fail, then Crewe took a view and amended this to 10 years I think! Bit like the battery in seat memory. |

Thanks Mike I am considering using 8mm plastic coated Yorkshire pipe for my fuel system as the plastic covering protects against abrasion and stone damage. Most 8mm copper tube has a wall thickness of only .6 mm. This is available for around £25 for a 10m roll. Trevor |

Hi, My service manual advises changing the drive belt every 36,000 mls (48,000Kms) or every 36 months Regards Darryl |

The belts do seem to last much much longer than the suggested periods. There seemed to be a spell of broken belts and I wondered if there was an iffy batch. Many cars are still running on their original belts. Distributors without points are a double edged sword. No need to open them up to change the points - so they don't get opened up to be lubricated - so the bearings go or the bob weights seize. Both much bigger jobs than changing the points. Lube yours soon. Driving without all 8 cylinders firing is bad news. From petrol wash removing lubricant from the cylinder walls and diluting the engine oil, and also from cooking your cats . . . which is never good in any scenario. I've never seen plain copper tubing wearing through, but plastic covered would not be a bad idea. |
