MAN Indicator oil pressure gauge gearbox 51274107012

About this part

Genuine MAN gearbox oil pressure indicator for the D2862 LE463 and related installations. A marine gearbox depends on oil pressure to engage and hold its clutches, which makes this reading a direct indication of whether the transmission can transmit power rather than a general health measure. Falling pressure precedes clutch slip, and clutch slip destroys plates quickly. That makes it a gauge worth watching in the same way engine oil pressure is watched, and a falling trend is a reason to investigate rather than to monitor — the failure it precedes is expensive and develops quickly once it starts. Noting the pressure at a known load and temperature, once, turns this gauge from decoration into a diagnostic instrument. Falling pressure precedes clutch slip, and clutch slip destroys plates quickly once it begins.

Supplied new, in the manufacturer’s packaging, with our warranty of up to 24 months.
