Drive Chain Oiler
The oil which lubricates the chain is fed from the
center of the shaft, through the porous sintered oil
reserve element
(J),
along the outer
surface
of the
rubber orifice
@,
out the oil passage
©
and
along the surface of the drive sprocket.
To simplify the procedure for regulating the feed
of the lubricant, it is performed by the adjusting
screw
CD
in the chain oiler.
Turning the screw
clockwise
(A
direction} will force the rubber orifice
against the oil reserve
element,
causing it to ex-
pand and restricting the flow of oil around the
rubber orifice.
Turning the adjusting screw counter
clockwise (B direction) will permit the rubber orifice
to serink toward its normal size and allow greater
oil flow.
In other
words, the change in the di-
ameter of the rubber orifice
regulaters
the amount
of
oil
to lubricate the drive chain.
Adjustment Procedure,
I .
Remove the rear crankcase.
2.
Wipe the oil on the drive chain thoroughly
with a rag.
3.
The adjusting
screw
is adjusted to maximum
oil flow on all motorcycles leaving the factory.
After riding for a short period, if excessive oil
is noticed by indication of chain oil on the rim,
fender, spokes etc., turn the adjusting screw
about 1
/4
turn in the clockwise direction and
recheck the oil flow condition after riding for
one minute at 50~70mph
(80~11 Okphl.
The
adjustment is proper if the chain link plates
and
rollers are wet
with
oil and the other areas are
free from excessive oil.
4.
Readjust the screw if necessary until the proper
oiling condition is obtained.
Supplement Lubrication
Drive chain rollers and side plates must be
properly lubricated at all times.
Sustained high-
speed driving
or
improper
adjustment of
the chain
oiler may cause inadequate
lubrication.
If
the rollers
or side plates are dry or
show
evidence
of
rust,
apply a high-quality chain lubricant according to
the manufacturer's instructions.
