Painted the roadwheel tyres & added to the chassis - then, adding the tracks - one side at a time, so I don't mix the parts up!
Starting at the drive sprocket, the correct curved track section was CA'd into place, making sure it's the right way round.
The next section is offered up, then drops of CA fix it in place.
After the bottom straight run is added, the curved section is added to the idler wheel ( the idler wheel can me moved around eccentrically , so the track section fits neatly ). If all is well & you have got the right parts, the final lower section is fitted.
When you come to add the final top run section it should fit neatly, providing you have been accurate in your assembly. All it needs is the outer drive sprocket adding & the paint on the tracks touching up.
I use Loctite CA, it has a long nozzle & I can just add a dot of CA where I want (& the nozzle doesn't clog as badly as some other makes ). The instant grab of CA is essential for me - I don't like sitting around, holding parts together.
I'll do the other side, add the outer sprockets & touch up the track paint, then I can put this aside, and move upwards.........
