Thanks for that. I've found a couple of posts relating the same problem with the suggestion that there might be a missing or damaged tooth on the flywheel. However as a second or third press on the starter button without any movement of the vehicle (and thus the flywheel) always starts her up without any further problem it seems unlikely as presumably the relative positions of the flywheel and starter would be unchanged. Would it be straightforward to remove the starter motor myself and lubricate the pinion shaft?

Thanks, but wouldn't a faulty solenoid just make a fairly quiet 'click' or 'clunk' without actually spinning the starter motor? It sounds as if everything that should happen when you press the starter is happening apart from the starter pinion engaging with the flywheel. |

pinion not sliding on its shaft, you could lubricate the shaft, this may only work for a while

Thanks Chicken George, I reckon we have come to the same conclusion - pinion not sliding freely on the motor shaft. As I said in my first post this only happens infrequently but when it does it is usually when there is an audience or in a multi storey car park where the awful noise is greatly magnified. I think I'll give the lubrication option a try.

I have a tractor with same problem, lubing the shaft helps for a while. for tractor new motor £500 service exchange £275.

If you end up lubing the shaft, you need to use a graphite or possibly silicon lubricant, not oil - it will pick up fragments of ring gear and other "stuff" floating around in the bellhousing and make matters worse

Thanks Chris B...I must admit that I hadn't thought of your second point re the solenoid operation. It used to be so much easier when you could just tap the starter motor with a tyre lever. What with the problem only manifesting itself occassionally and the intervention of the Festive Season I haven't investigated further to see if I can remove the starter motor from below far enough to lube the shaft or whether I have to go the whole hog and approach the job from above with all the associated dismantling and reassembly. I'm almost minded just to leave it alone until it eventually fails and then throw the problem back at the dealers!
