• 3 piece thrust bearing (MA131-66)
outer race with larger I.D. (inside
diameter) installs closest to hub.
• Grease the center ball cage of the
thrust bearing. We recommend using
MA3200-06 Tri-Flow synthetic grease.
• Only hand tighten MA0061 Socket
Bolt until it is moderately tight. Do
not overtighten bolt or it may result
in fatigue to bolt. Use green thread
lock on these bolts.
Note:
Blade grips will have some axial
play. This is normal.
