ALL-REMOVE AND REPLACE
PLASTIC TIP
1. Disconnect speedometer cable casing from speedom-
eter head.
2. Slide old cable out from upper end of casing, or if
broken from both ends of casing.
3. Take short piece of speedometer cable with a tip to
fit
speedometer and insert it in speedometer socket.
Spin short cable between fingers in direction that
higher speed is indicated on speedometer dial and note
if there is any tendency to bind. If binding is noted,
there is trouble inside head and speedometer should be
repaired.
4. Inspect cable casing, especially at transmission end,
for sharp bends and breaks. If breaks are noted,
replace casing.
5. To insure quiet operation, assemble cable in
following manner:
a. Wipe cable clean, using lint free cloth. Flush bore of
casing with oleum spirits or suitable solvent solution
and blow dry with air under pressure.
b. Place an approved speedometer cable lubricant in
palm of hand.
c. Feed cable through lubricant in hand and into
casing until lubricant has been applied to lower
two-thirds of cable. Do not over-lubricate and .do not
apply lubricant to upper third of cable, since operation
of cable assures adequate lubrication of upper third
and at same time prevents lubricantfrom seeping into
speedometer head.
6. Seat upper cable tip in speedometer and snap
retainer on casing.
