Yesterday I removed one of the
banjo bolts that serve as oil injection ports on the housings of my 20B. In
the bottom of the threaded bore I noticed a slotted plug with hole in center.
I wondered if the slot had something to do with maybe distributing the oil to
the tip seals. It looked like it was threaded in; so in my curiosity, I
took a screwdriver to screw it out. It turns, but doesn’t appear to move
up or down. What is it there for, and did turning it do anything?
I want to make sure it doesn’t possibly move inward and contact the tip
seal.
BTW; the hole is threaded 10mm,
1.25 pitch; and a plug bolt should be a max of about 12mm
long.
