About This Crawler Crane Sprocket
On the Kobelco 7035, the sprocket sits at the rear of the crawler frame and drives the track chain. Each tooth takes one link pitch per revolution. When the tooth face wears unevenly — one side cutting faster than the other — the chain starts skipping at the pickup point. On a crane doing short-radius picks all day, you see that in the tooth profile within six months. On a machine that mostly travels site to site, it takes longer.
The 7035 frame takes a specific tooth count and pitch. 2404J120 is the number that locks that down. Put in a sprocket from a nearby model and the pitch is off by half a step — the chain finds it on the first full travel run. The bushings start wearing on the flank instead of the tip, and you will see elongation in the chain within 200–300 operating hours. That is when Kobelco 7035 sprocket replacement turns into a chain replacement job at the same time.
To check wear: look at the tooth tip at the contact face. When it narrows to a sharp edge or hooks to one side, pull the sprocket — it is done. Leave it another month and you are replacing chain too.

Related Kobelco 7035 Undercarriage Parts
The front idler is the other end of the same chain loop. When the sprocket teeth are worn down, check the idler tread face and shaft play while the sprocket is already off — both parts take the same chain load and the wear timing is usually close. A new sprocket running against a worn idler tread will show tooth wear on the drive side again within the first season.
