Hi I have an old thwaites dumper which has developed a loud clunking noise when accelerating in all gears. Made worse when loaded. Any ideas on this ?
Thanks

Thanks I shall check the shaft joint. I did wonder if the drive chain on the clutch was jumping as it seems very slack. But the shaft joint seems more likely now you've mentioned it. It's hard to work out where it's coming from by one's self when driving it. Thanks again.

Or the chain and sprocket from clutch to gearbox?

Can you adjust the tension on the chain ?

If it’s clunking badly it may be the sprockets worn out can you take the covers off the clutch?

The very similar Barford dumper did have a cover if I remember? I think this dumper needs the box moved to adjust the chain!

They are a bit worn but as you an see the chain is very slack too but as you suggest the sprockets are probably the cause. Any suggestions for getting spares ?
Thanks for your help.

on my Alligator you can adjust tension by adjusting motor position ..... that looks to have an adjuster on the gearbox ? could be missing a nut or two

Just moved the motor over to the right and that has tightened up the chain right enough and clunking has stopped 
was a nice Sunday morning job with plenty cursing involved!..... its running so well now I guess I had better fix the brakes
