Any help on exactly where to oil and where to grease an Abu round reel? 

Grease on gears, pinion yoke, driveshaft stud, and brake plate where all sliding parts go.  A little grease on the pinion yoke studs as well.  Oil the spool bearings, worm gear, worm bearing(s), and a drop of oil on the idler gear stud.  Run the idler gear and worm cog dry.

as a rule, grease is for contact stress (gears) and oil is for rotating spindles and bushings. 

 

You don't want to use too much oil, because it will collect and form a running film, so use it judiciously on things that spin and pivot. 

A/R roller bearing gets grease, but the sleeve that goes over it gets one drop of oil. 

 

I use a flat-end sable artist's brush for applying grease - that way I can get the gear teeth fully and keep it light, also the ratchet teeth on the main shaft. 

 

Keep in mind all you want is a film - you don't want excess of any lube. 

Man I really don’t know what I’m doing. 
 

I pushed the new idler gear on, It clicked but now has up and down movement on the stud. When I popped It back off, It left the bearing on the stud! 
 

The new spool bearings came open but came with little orange rubber pieces. I’m assuming these go on either side of the bearing? 
 

The new spool gear does not push into the spool like It does on the old spool. Is this ok?
