One Tooth, Four Shanks

Everything about this tooth is decided by the machine class except the shank it sits on. 207-70-14151 is the PC300-class point; the 207-939-3120 adapter that carries it is welded to the bucket lip and is catalogued in four gap widths. Two machines of the same model, with buckets built by different shops, can need different shanks and identical teeth.

Because the adapter is the expensive half, it pays to check the nose before buying teeth. If the pin hole has gone oval or the tooth rocks on the nose, new teeth will not fix it — and a tooth that hammers on a worn nose loses its pin, then the bucket starts cutting steel against rock. The order of work is shank first, tooth and pin second.

Profile Choice on the Same Pin

ProfileWhere it earns its keepNote
207-70-14151 standardMixed soil, sand, gravel and general trenchingThe default PC300 point
207-70-14151RC (rock chisel)Rock, laterite, broken concreteNarrower tip, more penetration
207-70-14151TL (tiger long)Compacted ground, clay, root cuttingLong tip; popular on trenching buckets
207-70-14280 longDeeper cut, longer wear faceSame pin and shank family; catalogue weight is quoted anywhere from 6.6 kg to 9.5 kg

All of them take 09244-02516 and fit the same adapter, so a mixed set needs one pin number in stock. On most PC300 buckets we quote, buyers run standard tips on the outer positions and rock chisels in the centre where the load concentrates.

Weights, Sources and What We Do Not Publish

This tooth is quoted from 6.2 kg to 7 kg, and the long version from 6.6 kg to 9.5 kg, depending on which catalogue you read. That is the honest state of the trade data for cast GET: part numbers and pin sizes are firm, weights are estimates for freight. We show the spread rather than a single number we cannot defend. We do not publish prices, because a quote depends on quantity, profile mix and shipping lane, and we do not quote wear life in hours — ground conditions and operator habits decide that far more than the steel does.

FAQ

Q: Which machines does the Komatsu 207-70-14151 tooth fit?
A: Aftermarket compatibility lists name the PC300, PC310, PC350 and PC360 families, and several also list PC220, PC240 and machines such as the PC300-8 and PC360-7. Send the model and serial prefix: the tooth number is stable, the shank behind it may not be.

Q: What pin holds the 207-70-14151 tooth?
A: 09244-02516, also written 175-78-21810 — 25 mm diameter, 120 mm long, with a 27 mm head, quoted at 0.42–0.43 kg in the catalogue we checked. Quote both numbers on the enquiry.

Q: Do I need a 40, 45, 50 or 55 mm adapter for this tooth?
A: The tooth fits all of them; the gap belongs to the bucket. The shank 207-939-3120 is sold as PC300-40, -45, -50 and -55, with catalogue weights from 12.1 kg to 15.05 kg. Measure the strap gap on your adapter before ordering.
