Описание
A pump that spans two hauler generations is genuinely useful for a fleet carrying both. It is also the sort of listing that gets stretched too far, so here is what the evidence supports and where it stops.
Применимость и подтверждение
Volvo A25F, A30F, A35F, A40F and the matching G-series A25G, A30G, A35G and A40G articulated haulers, described in dealer parts data as a main hydraulic pump. Volvo’s own online catalogue does not return a citable page for 15140666, so the machine list is dealer-established rather than manufacturer-confirmed, and no displacement, pressure or flow figure is published for it here.
Where a two-series listing stops being helpful
Volvo carried the pump train forward from the F series into the G series, so a shared part number is plausible. What does not carry forward automatically is the control setting: pressure cut-in, flow priority and the regulator arrangement were revised on some G-series builds. A pump that is physically identical and set up differently will fit, run, and leave the machine slow to tip. Confirm from the number cast on your pump and the machine serial prefix, not from the model letter alone.
Диагностика и установка
- Judge the pump hot: hoist and tip times lengthen as oil temperature rises.
- Исключите настройки предохранительных клапанов и клапан удержания кузова, прежде чем признавать насос неисправным.
- Noise under load points at cavitation, so check the suction line and strainer.
- При установке сверьте шлицы вала, центрирующий поясок, фланец, расположение портов и ориентацию управления с демонтированным насосом, заполните чистым маслом перед прокруткой, замените элемент возвратного фильтра, обеспечьте неограниченный слив из картера в бак и стремитесь к ISO 4406 18/16/13.
