Harley Davidson Panhead. Service manual (1948-1957 Rigid) - page 11
Lubricate back of pawl carrier with "Grease-All"
grease and install cover gasket (8) and cover (7) so notches at top line
up with corresponding notch on adapter plate. Apply Loctite sealant,
to threads of shorter screw (5) and insert through bottom hole. Secure
with nut (6) on back of adapter plate. Apply Loctite sealant to threads
of five long screws (4) and tighten all screws.
Position cover dust shield (3) over dowel pinson pawl carrier. Position
shifter shaft lever (2) over dowel pins and secure with three shifter
shaft lever screws (1). Also treat the threads of these screws with
Loctite sealant before inserting.
REPLACING SHIFTER COVER
Coat shifter cover gasket with Perfect Seal No. 4 and position on gear
box. Install assembled shifter cover over gear box opening and secure
with twelve screws. Note that two screws are longer. They are inserted
in holes adjacent to bulge in cover over shifter gear. The short cover
screw with vent hole is inserted in hole nearest locating dowel pin on
right side of gear case. Use Loctite sealant on all screw threads except
the single vent screw.
REMOVING SHIFTER FORKS (FIG. 4D-9)
Remove shifter cover as described in "Removing Shifter Cover.”
Shifter fork shaft (2) is held in position by lock screw (1) which may
be found in gear box cover joint surface in line with right end of
shaft. With lock screw (1) removed, shaft may be driven out by means of
a
drift inserted in hole in starter cover joint face
of gear box. Notice that a rubber oil seal (3) is assembled in groove on
left end of shifter fork shaft.
Shifter fork assemblies (A and B) are not interchangeable. Note exactly
the arrangement of parts and components in each. Keep parts separate to
avoid needless adjusting when reassembling. If inspection shows fork
assemblies are not damaged, worn or bent, it may not be necessary to
disassemble them unless shifter clutches are replaced. Adjustments are
described in "Assembling Shifter Forks.”
DISASSEMBLING SHIFTER FORKS (FIG. 4D-9)
If it is necessary to disassemble shifter forks, lift off shifter finger
rollers (4), pry back ear on lock washer (6) and turn off nut (5). Lift
washer (6), a number of .014 in. or .007 in. spacing shim washers (7)
which varies from one fork assembly to another, shift forks (8), 5/64
in. thick standard spacing shim (9), more .007 in. or .014 in. spacing
shims (10), shifting fingers (11) and shifting fork bushings (12).
CLEANING, INSPECTION AND REPAIR
Clean all parts in cleaning solvent and blow dry with compressed air.
If shifter forks are bent or worn, replace them. Straightened forks are
weak. They may break and cause extensive damage to gear box parts.
Check fit of shifter fork bushings on shaft. If bushings are loose
enough to give fork action lash, replace them. Check replacement part
fit on shaft.
