Dear John, without the Kingfisher manual so I can check the gearbox internals it is hard to say, but two things come to mind. You mention UJs (Universal joints). If these are Hooks type joints as used on older cars then they are not designed to take end thrust so a thrust bearing or plumber block should have been fitted to the prop shaft itself. Has this got wear in it allowing the shaft to move back and forth under prop thrust? This is also the symptoms of a drive plate starting to fail, but I am afraid that I do not know if Kingfisher use one. If they do I would suggest the gearbox is taken off so you can inspect the plate. Loose engine mounts may also do that if the shaft is passing prop thrust to the engine. I hope this is of some help. Darglow Engineering deal with Kingfisher engines. Tony Brooks

Right. We need to find out if its a Kingfisher box or one of the readily available ones. I think I have seen a PRM on a Kingfisher, but I have also seen their own box. If it is NOT a Kingfisher box it will almost certainly use a drive plate, especially if the flywheel is in the normal "vehicle" place at the back of the engine. If you email a digi-pic of the gearbox to Tony@TB-training.co.uk I will see if I can identify the box. If a drive plate is needed most larger chandlers and engineering outfits can obtain one to pattern, but the gearbox will have to come off to check it.Tony Brooks

Hello Tony There is a KD26 Manual available on my website at www.kingfisherdieselengines.org It may help you to answer John Boy's question.

Many thanks for that. This sort of info is like rocking horse dung! The gearbox appears to be driven by set of radial fingers with rubber bushes on the end. These bushes fit into the flywheel. My guess would those bushes have disintegrated, so the gearbox needs to come off for inspection. All those readers with Kingfishers - please bookmark that site. Tony Brooks
