How the 35S Tooth Is Held
The 35S point is a top-pinned tooth. The casting drops onto the adapter nose, the lock pin 4501627 is driven down through it, and the rubber lock 4501625 is snapped into place to keep the pin in the pocket. There is no horizontal pin and no side hole, which is the quickest way to tell this family from the 205-70-19570 tooth Hitachi lists alongside it for the same machines.
| Item | Number | What it does |
|---|---|---|
| Tooth point | 4427919 (35S) | Digging point; listed by Hitachi for the ZX200-220 class |
| Lock pin | 4501627 (35PN) | Holds the point down on the nose |
| Rubber lock | 4501625 (35-40LK) | Keeps the pin seated; the part that is usually missing on a thrown tooth |
| Weld-on adapter | 20Y-934-2211, V29, F3610T-35 | The noses Hitachi lists for this class — the nose decides what fits |
| Side cutters | 2014503 / 2014504 | Corner protection listed in the same class |
The Check That Stops a Wrong Order
Two numbers come back from suppliers when you ask for a "ZX200 tooth": 4427919 (this one) and 205-70-19570, which is a Komatsu-format tooth number that Hitachi's own list carries for the same ZX200-220 class. Both are legitimate answers to the same question, which is exactly why the decision has to be made on the bucket rather than on the machine plate.
Look at the old tooth before it goes in the scrap bin. If the pin hole passes through the top of the casting and there is a rubber lock sitting over the pin head, you are running the 35S system and this is your tooth. If the pin goes in from the side through the tooth and the adapter, order the side-pinned family instead. Take one photo of the adapter nose with the pin in place — that single picture, with the machine model and serial prefix, is usually enough for us to confirm the family without the old part number.
Hardware Discipline
The rubber lock is a consumable with a shorter life than the tooth it holds. When it perishes, the pin walks and the tooth leaves the bucket, often bending the adapter nose on the way out. Order one pin and one rubber lock per tooth, keep a few spares in the tool box, and rotate teeth between centre and corner positions at each change so the corners are not doing all the work.
What We Do Not Publish
No price and no wear life in hours. Price depends on quantity, profile mix, whether pins and locks are on the same line and the shipping lane; wear life depends on your ground and your operator. What we do publish is checkable: the part numbers above come from Hitachi's own selected-parts list for the ZX200-220 class, read 30 September 2026, and the catalogue weights are marked as catalogue figures. Send the adapter photo and the quantity and we quote the teeth with their hardware.
FAQ
Q: What pin and lock does the 35S tooth use?
A: Lock pin 4501627 (35PN) and rubber lock 4501625 (35-40LK), as listed by Hitachi with the 35S point 4427919 for the ZX200-220 class. Order one of each per tooth plus spares.
Q: How do I know my bucket takes 35S rather than a side-pinned tooth?
A: Pin direction. A vertical pin pressed down through the top of the tooth means the 35S system; a horizontal pin through the side means the 205-70-19570 family, which Hitachi also lists for the same class.
Q: Which adapter does this point sit on?
A: Hitachi lists 20Y-934-2211, V29 and F3610T-35 for the ZX200-220 class. They are different castings, so measure the nose width and pin hole before ordering in volume.
Q: Is this a genuine Hitachi part?
A: No. It is an aftermarket replacement cross-referenced to the Hitachi number, and we describe it that way. Grade on the castings we ship is quoted at 48–52 HRC with impact values above 20 J per supplier data.
