Solenoid cross-reference (for Bosch starters)
Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
The original Bosch part number is 0-331-302-022 or 0 331 302 022 or 0331302022. Here are several generic cross-references for this solenoid. I haven't tried all of these myself, but I understand they work just fine.
Thanks to Steve Janowick for sending me the following information via email. In Steve's own words:
Although I do not have the Bosch numbers I did find a listing for two different solenoids for the two different Bosch/Guzzi starters at Euro Moto Electrics.
The solenoid for the early Loop frame starter Bosch# 0001157006 used a solenoid with a 7 mm plunger slot and the later Tonti frame starter Bosch# 0001157016 used a solenoid with a 11 mm slot
.
- The Solenoid with the 7 mm slot for to Loop frame is EME part number BO157-sol1.
- The solenoid with the 11 mm slot for to Tonti frame is EME part number BO157-sol2.
