I'll see what I can dig up about the slacker 543301 bearing Ted, for awhile ago I was in toutch with a company who could get the 543301, I think the price was around 40-50$ each + shipping, but I got busy with other project in the meanwhile. Maybe it's time for me to order one bearing and check if it's the real thing
if it's the real thing I'll give you all links and contact info.
Cranks... they used 4 different cranks.
Picture show crank 503 53 67 02 to the left and crank 503 53 67 04 to the right, 12 mm vs 13 mm conrod bearing (when we study the cut in the con rod pin to the axel it's easy to see that the 04 has bigger conrod bearing)
503 53 67 01
12 mm conrod bearing
42, s/n 0450748 ie year 90 week 45
242 SE, s/n 0130392, ie year 90 week 13
242 SG, s/n 0130001, ie year 90 week 13
503 53 67 02
12 mm conrod bearing
42, s/n 4110291, ie year 94 week 11
242 XP, s/n 4130001, ie year 94 week 13
242 XPG, s/n 4110001, ie year 94 week 11
503 53 67 03
13 mm conrod bearing
This crank was solely used as substitute crank for the 01 crank.
503 53 67 04
13 mm conrod bearing
This crank took over after the 02 crank, and it should only be used in crankcases after those s/n's:
42, s/n 0450748, ie year 90 week 45
242 SE, s/n 0130392, ie year 90 week 13
242 SG, s/n 0130001, ie year 90 week 13
A 246 crank is far as I know crank 503 53 67 04 since 246 arrived after 1994 week 13 far as I know about.
