Hi Allan,
Welcome to the Kenevo club!
Can't help with the bearing chart. My Kenevo Comp has covered 850 miles and I have had a few similar problems.
I've also had a problem with chains but EMC have been very good by supplying new chains free of charge.1st stock chain measured >0.5% after 80 miles. 2nd chain measured > 0,5% after 80 miles too, 3rd chain measured > 0.75 after 400 miles, 4th chain was jumping on cassette when fitted so had to fit a new cassette at the same time. So far the 4th chain and new cassette have lasted 250 miles and chain has not yet reached the 0.5% limit - best so far. I fitted a Sunrace cassette as gear ratios are better and the Shimano cassette was worn very badly especially in lower gears (largest cogs). 4th chain is an EMC e11 EPT chain and seems to be lasting the best of all the chains. KMC maintenance guide offers some good advice see:
MAINTENANCE
One of my rear wheel bearings is beginning to feel a little rough when rotated with my finger but I've also had to re-tighted the wheel axle lock nuts a few times as they've worked loose. Maybe this is your problem?
Latest problem I'm having is that the battery will not charge and charger LED illuminates Green indicating fully charged even though the battery is only at 5% according to Mission Control which also shows 100% healthy battery. Charger has already been replaced under warranty but this did not resolve the issue so I'm waiting to hear back from Specialized about next steps. Hopefully a new battery. Everything works fine apart from the battery charging. Has anyone else had this problem?
Other than those issues I'm really enjoying my Kenevo but wish it was as reliable as my son's Trek LT7 which had a chain replaced at 300 miles (>.75% wear) but no other problems and has now done 400 miles on similar routes as my Kenevo.
Cheers
Brian
