[QUOTE="Vincent Brake, post: 171688, member: 398"] Its is Greg, from '14isch. 1330cc Its the 3rd main starter sprocket. Were made of C45. Than carbonitrided. But core to hard. Hence no ductility. Braking theeth.... Now made of EN36C got a blank from HPC grears. Made me 2 extra..... I guess now that the failure is due to not hard enough engaging forward, the little pinion in the big gear. Saw that when i was ready....as it was axially floating forth and back not a small amount.. So i tried to stiffen up the spring on the bendix solenoid inner core. Problem: pinion was not put back when at rest. So moved the whole core back by 1.5 -1.8 mm (machined the plasitc part in picture above) and put in a 4 mm ball onto the pin (witch is spring loaded in the solenoid core) Now there was sufficient load to keep it forward during start. Reason to do the work; dicided to ease up by these decompressors. And put in a new ESA. Made some years ago, by my Son Bart. But reading you put in an decompressor..... makes me.... Hope its not uselesss. And in the process got to understand a Harley part very well... Next is a small video. And btw. Amazing i can type this all on such a silly Samsung. Very well working site this. [/QUOTE]
