5.
Tap outside of gap piece with a dead blow
hammer to loosen it, and, with the help of
another person, remove gap piece.
Re-installing Gap
1.
Clean all mating surfaces completely with
mineral spirits and inspect and remove any
burrs. ALL MATING SURFACES MUST BE
ABSOLUTELY CLEAN!
2.
Lightly oil a lint-free cloth with way oil, and
rub a thin film into pores of freshly cleaned
gap surfaces. Next, place gap in position on
lathe bed.
3.
Back off threaded dowel pin jam nuts until
they are flush with end of pins, then drop pins
into pin holes in gap.
4.
Jostle gap closer to its final alignment until
pins seat naturally.
5.
Install and lightly snug four cap screws in an
order that will draw gap closer into alignment.
Using blocks of wood and clamps to get mat-
ing surfaces into alignment can also be help-
ful.
6. When alignment and flush mating is accept-
able, tighten four cap screws in a pattern that
will maintain or improve the alignment.
7. Wait 24 hours, and check for quality of mat-
ing. If unacceptable, use clamps and blocks
of wood, and loosen and tighten appropriate
cap screws to draw-in and release certain
areas of gap to achieve the required align-
ment.
8.
When satisfied with alignment, tap dowel pins
the rest of the way into the gap until they are
in a fully seated position, and thread jack nuts
down until they just contact the gap.
9.
Tighten preload cap screw inward until it con-
tacts headstock and resistance can be felt,
then tighten it an additional

Brake Shoes
If the brake responds poorly, verify that the all link-
age is tight and that the belts are tight and free of
oil or grease. Replace the brake shoe set if the
lining thickness is ⁄ " or less. When inspecting

for amount of brake wear measure from the fol-
lowing locations:
• If riveted linings are used, the measurement is
taken from the rivet heads to the lining surface
as viewed from the brake pad surface.
• If bonded linings are used, the measurement
is taken from the metal shoe surface to the
surface of the lining as viewed from the side
of the brake shoe.
When inspecting the drum, if the drum pulley is
bell-mouthed, cracked, or shows deep groves,
replace it. For minor scoring, the drum pulley can
be dressed with sandpaper or turned on a lathe.
