BGM gear shoulder rings are manufactured with high precision. They are hardened and ground plane-parallel to the hundredth of a millimeter. They therefore correspond exactly to the specified dimensions. The quality assurance guarantees a maximum deviation of only four hundredths of a millimeter undersize. This makes the BGM discs much more precise than Piaggio shoulder rings. WHY shoulder rings are used to compensate for the axial play between the gear wheels. The distance between the gear wheels is essential for a smoothly working gearshift. The closer the game is selected, the less the gear wheels can slip sideways. The gear change is more precise because the gearshift cross now engages exactly in the middle of the gear wheel and does not first push it away. It is therefore worthwhile to precisely measure the transmission. HOW MUCH The play specified by Piaggio is 0,15-0,40mm. It is determined with a feeler gauge between the gear wheel and the shoulder ring. DIFFERENCES The original shoulder rings are available in two versions: Thick (2,0-2,5mm original with only one nose) suitable for Vespa Largeframe from 1952-1984 Thin (0,9-1,4mm with four noses) suitable for Vespa Smallframe and Vespa Largeframe from 1984 (main shaft with two shoulder rings / circlips) OLDIES The thick version of the shoulder rings for Largeframe Vespas before 1984 has not been available from Piaggio for some time. The matching shoulder rings in the range of 2mm to 2,50mm are available for these gears ...
