Royal Enfield METEOR MINOR STANDARD 1958 Workshop Maintenance Manual page 7

The distributor is driven by a separate
endless chain from the rear camshaft sprocket in
the timing chest. The tension of this chain is
adjusted by moving the distributor fixing bolts
in their slotted holes.
13. Ignition and Lighting System. (See
Section G)
Separate systems are provided for ignition
and lighting. The distributor is chain driven from
the inlet camshaft at half engine speed and has a
built-in automatic advance mechanism.
Lighting current is supplied by the battery
which is charged through a rectifier from an
alternator consisting of a rotating magnet
mounted on the crankshaft and running in a
six-coil stator in the primary chaincase.

15. Air Filter
The air filter is a Vokes Micro-Vee felt and
gauze dry filter, 5 in. diameter and housed in a
compartment of the toolbox.
16. Lubrication System
Lubrication is by the Royal Enfield Dry
Sump system which is entirely automatic and
positive in action. The oil tank is integral with
the crankcase, ensuring the full rate of
circulation immediately the engine is started and
rapid heating of the oil in cold weather.
There are two positively driven piston type
oil pumps running at
rear of the timing cover for pumping oil to the
bearings under pressure and the other at the
front for returning the oil from the crankcase to
the tank. The return pump has a capacity
approximately double that of the feed pump
which ensures that oil does not accumulate in
the crankcase.
The oil from the big ends drains into the
bottom of the crankcase and is prevented by a
baffle from being drawn up by the flywheel.
The oil from the rocker bearings is squirted
through a small hole in the rocker on to the top
