With a blunt chisel or screwdriver, drive a portion of the bushing into
the notch previously tUse sump or cover with 7/8" diameter bearing
and 19094 guide.
Reassemble sump to cylinder with pilot guide bushing in the sump
Place finish reamer on pilot and insert the pilot into the cylinder
bearing until the tip of the pilot enters the pilot guide bushings in the
sump bearing. Fig. 10.
Lubricate the reamer with kerosene. fuel oil or-Stoddard Solvent. then
ream the bushing turning the reamer clockwise with a steady even
pressure until reamer is completely through the bearing. Improper
lubricants will produce a rough bearing surface. Remove sump and
pull reamer out without backing it through the bearing. Remove pilot
guide bushing: clean out all reaming chips.
On most cylinders. the breaker point plunger hole enters the reamed
out main bearing and .a burr is formed by the counterbore reaming
operation. Burr can be removed using 19058 finish reamer. Clean out
dirt and reaming chips.
