Bu99er ! Picked up a JCB Micro digger to do some work at the weekend, moving it in to place just now, caught a rock and one of the rubber tracks has jumped off. Hire shop is shut until Monday and was hoping to use it tomorrow if it stops raining.
I can lift that side with the missing track clear of the ground with the bucket. Assume there must be some sort of tensioner I can release that allows me to refit the track? Anyone know how it works ?

IIRC there should be two nuts on the side that will loosen the side panel and then under there you will be able to shorten the shaft and put the track back on.
Its easily sorted as long as the track isnt damaged.

you shold be able to get it on with a bit of work. there is a panel on the side of the track housing that you remove inside is a nipple that you have to pump grease into to push it out to tighten the track. be careful if someone is barring it on as it is dodgy if you dont know what you are doing.

THANKS GUYS.
What did we do before great websites like this !
Just took a few minutes to fix this morning, a bit chilly and damp but now it's fine and the sun is shining - looks lovely reflecting on the ice (!).
For ref the digger is a brand new 2008 model JCB Micro +. There are no plates to remove, once track is off you pull out the front idler wheel assembly and there is a telescopic damper on the back that is pressurised with grease and held back with a spring. Unscrew where the brass grease fitting screws in to the black housing (pair of spanners about 24mm) remove it and push back in and a sausage of grease comes out. Nothing is under pressure so easy to do.
Then grease bit then screws back in and pushes the whole lot back in to the track assembly. Make sure grease fitting faces outside. Track goes on the back first, needed a good push to get it on drive cog, then with a bit of a nudge the track hooks around front idler wheel. Now just pump tensioner out again using grease gun on fitting which you can reach through a gap in side track housing. Job done.
You would be stuck without a grease gun but in a "circle of life" moment the reason I'm doing this job is to provide hard standing for classic cars so a grease gun is always at the ready in me garage !

Well done on a good repair job there!
We've refitted [rubber] tracks on site before, but with the aid of no tools........just another digger bucket......
