hi GarrettSpule 4 said:Your model pre-dates 1988, that is when they went to the updated drive with skates.
As for the bearings, the axles should be fine unless the gears are worn, it will be the block itself. So if your gears are good, then you need not get the gear set.
The paper work shows the purchase date,
so it could well of sat on some dealers shelf for a while.
The gears look OK now i have bit the bullet and stripped it right down, but there is a slight ovaling effect on one side of the chassis, but it is well less than 1.5mm so not 'overly' concerned YET.
But will still look out for the bushes and the gear set, for future use

thanks again for your help and info.
Still pritty chuffed that it runs so well for £22 and a couple of hours fettling
