Better to just measure the journals and know what bearing to buy, then to
research only to find errant info.
The bearings only come in .010 incriments, generally starting at .020.
On the timing cogs, you cant tell by looking at chain slop if its new or
old, the chains just dont stretch that much with time.
Look for wear on the insides on the teeth on the cog, and look for
a tight fit between the rollers on the chain, and the insides on the
cog teeth.
The alpine uses a double roller chain, and you'd have to put a great deal of
miles on one before it wasnt suitible for reuse.
The cogs seem to last a long time too.
