Deskripsi
Two numbers circulate for the same pump on the F-series haulers, and the difference between a supersession and a supplier’s guesswork decides whether a buyer gets the right part. This page publishes both numbers with the evidence attached to each.
Kesesuaian dan bukti
Volvo A25F, A30F, A35E, A35F, A40E and A40F articulated haulers, described in dealer parts data as the main hydraulic pump. Volvo’s own online catalogue does not return a citable page for 15079594, so the machine list is dealer-established rather than manufacturer-confirmed.
What each number means
| Nomor | Where it appears | Evidence status |
|---|---|---|
| 15079594 | Dealer parts data for the F-series haulers | Primary listing for this item |
| 17458125 | Listed by suppliers as interchangeable with 15079594 | Supplier cross-reference; no Volvo document confirming it |
| 9015079594 / 9017458125 | Same parts with a 90 prefix in supplier catalogues | Catalogue formatting variant, not a separate part |
Suppliers treat 17458125 as the later number in the 15079594 line. That is a reasonable reading of how the 90-prefixed pairs behave in some catalogues, but it is not a Volvo statement, so we do not print it as a supersession. What we do print is the safe rule: order against the number cast on your pump and the machine serial prefix, and we will confirm the rest.
How a hauler main pump fails
- Tip and hoist slow, worst on a hot cycle: internal wear and falling volumetric efficiency.
- Noise from the pump bay with a foamy tank: cavitation, check the suction line and strainer.
- Body drifts with the control centred: holding valve, not the pump.
- Shaft seal leakage: case drain back-pressure, often introduced during an unrelated repair.
