It came in the kit, as the kits you buy are for belt and gears. The only thing that hasn't been in the kit so far is the o-ring for the cam shaft seal retainer, which is a 50mm x 2.5mm and diesel pump gasket which I just made. The kit I got from Roodogs on eBay, it had new pistons, liners, bearings, full gasket and seal kits, sealant, and basic setting chart.
