Hello Andy, Here follows my headache-reason: I got the bicycle with a destroyed "Sprinter 5 speed coaster gear hub", made by Sturmey Archer. When dismantling, I found that this hub is a mixture of the good old "Sprinter Coaster Five Speed Hub Brake" and modern parts, because it is already equipped with the new "ball locking system" of the "Summit X-RD5". So I attach you several pictures: a) At first a look at the Hub Shell Assembly, which is in good order and nearly new. b) Totally broken ist the planet cage (Item No. 53 / Sales No. HSA 501 in the sprinter coaster spare part list) c) Totally worn are the three Pinion Pins (Item No. 14 / Sales No. HSA 502 in the sprinter coaster spare part list). d) Totally broken ist the Left Hand Ball Cage Assembly (Item No. 4 / Sales No. HSA 164 in the sprinter coaster part list). e) Totally worn ist the Primary Sun Pinion (ATTENTION: Item No. 53 / Sales No. HSA 575 in the Summit X-RD5 spare part list!!) f) When dismantling the hub and cleaning and sorting out the parts I lost the little Sun Pinion Spring (Item No. 52 / Sales No. HSA478 in the Summit X-RD5 spare part list)....... So I have also attached for you the two different spare part lists as pdf-Files. Thanks for all efforts -- let's hope that we'll bring the hub to life again. Sincerely Gunthard
