Kit comes with every gasket except the injection pump shim for the timing. Also has glow plug seals, valve seals, crank seals, every bearing for the crank and rods and wristpins. All 4 pistons with wristpins and rings, circlips. No bearings for the balance shafts.
You won't find it on any website and the box doesn't have a Kubota number that makes any sense.
So inside the box is 4 piston boxes, a bag with the crank bearings, an upper gasket kit and lower gasket kit.
Trust me when I tell you you won't need to look up any single gasket or seal because they are all there.
Apparently they haven't offered these complete kits for that long but surely I stand corrected by someone more in the know then myself.
My bearings look brand new as and I attribute that to regular oil changes with European spec 5W-40 synthetic.
The price of 4 pistons and the head gasket and 3 simple seals I needed were well over the $1300 bux I paid from an engine dealer for the complete kit, most of which will go in the trash.
