Sandvik 551 746 67 Indicator

The indicator, part 551 746 67, gives the operator or service technician a direct reading of a condition inside the machine, such as level, pressure, or filter restriction, without the system having to be opened up. Its value depends on reading true across the range that matters, because an indicator that sticks or drifts gives a reassuring reading at exactly the moment it should be warning of a problem.

Since a faulty indicator usually fails silently by showing a normal value, one that has been exposed to vibration, impact, or contamination for a long period is worth checking against a known reference rather than assumed to be accurate because it still moves. Stalroc quotes this Sandvik reference by part number and exports worldwide to mining, quarrying, and drilling contractors.
