Remove two capscrews (4) and plate (5).
NOTE
A new idler shaft will be installed. The new shaft diameter has been increased in the area that rides on the

ing must be discarded and new one installed.

Remove gear (6) and remove bearing (7) from gear. Discard bearing.
CAUTION
Do not reuse lock or nut. Bolt heads and nut could become embedded in the softer lock material causing a
possible loss of tightening torque. This could result in the failure of fuel pump drive idler shaft or thrust
plate.
