Piston pin 10 roller needle bearing
Only SkyHawk engines have the best quality 10 roller piston pin needle bearings as standard issue.
Competitors have the cheap 9 rollers. Advantage: SkyHawk
Both 9 and 10 roller bearings are interchangeable except for the quality difference. The extended life winner is the more expensive 10 roller as shown here-in.
