Volks,
This is great stuff! I appreciate it.
Ok, the seal in in - and it is tighter than Dick's hat band - AND it is
ever so slightly below flush - like 1/32 anyway. So I guess I'm good. A
little felt thingy is being sent to me to hold the grease in the pilot
bearing. Now about that little supposedly NLA metal washer/sleeve
whatever found on page 13.17 in the Bentley - to hold the felt washer
in place .............. any ideas? or suggestions for substitutes. Makes
sense to me that it should be there.
Thanks,
John Rodgers
