General information about this item
Product info
The compression spring with part number 1-0930 ensures the correct preload of the diaphragm in the BMW Isetta engine’s diaphragm breather, thereby defining the opening pressure of the vent valve. During an engine or breather overhaul, a fatigued or corroded spring should be replaced to ensure the original venting characteristics and stable crankcase pressure. This ensures that the crankcase ventilation system in the restored BMW Isetta engine remains permanently reliable.
