SB50/Spree crankshaft interchange?
Posted: Sat Jun 22, 2013 11:06 am
Hi,
We have a member trying to track down a crankshaft for the SB50. I note the SB50 had a different part number than all Spree's. Has anyone noted the difference (1986-87 Spree being the most likely retrofit) or swapped cranks?
13000-GS6-000 - SB50 crankshaft assembly
13000-GK8-780 - NQ50 1986-87 Spree crankshaft assembly
13000-GK8-303 - NQ50 1985 Spree
1986-87 Spree used the same bearings as SB50 and seals are the same. Yet SB50 has different part numbers for each crankshaft half as well as the entire assembly. So beyond bearings/seals, there may be a mechanical difference at either end.
