logo is up. Push it into the bore.
NOTE: Do not hit the cover with a hammer or mallet, shocks
may cause the cover thrust washer to dislodge and
drop into the gear cavity prior to the cover getting
positioned properly. If all the parts are to size and
assembled properly, the cover should not need
excessive force to assemble.
