So this older shimpo 21 is developing some side to side play and becoming more noisy under load.
I've serviced the bearing on a 70's rk(2?) and this looks a bit simpler but before i start removing things i figured i'd throw a picture out and see what advice might be available.
This pulley and the wheel head will wiggle
The other wheel needs service as well but i'm uncertain the exact model number. I found one video showing an RK2 with the round red and green on off buttons as well as direction toggle but every other picture i find does not show the on/off buttons so I'm unsure of the model number. If someone can confirm the model number for the 70's rk with round red and green on/off buttons I'll be more comfortable finding a bearing part number to match. I know i wrote them down some where but unfortunately not in my little black book.
any help or advice is appreciated
