SECTION D11
Service Operations with Engine Removed
Meteor Minor
1. Removal of the Engine Gearbox Unit from
the Frame
Disconnect the battery leads.
Remove the dual seat and petrol tank.
Remove the engine steady.
Remove the tool box cover and slide the
flexible connection to the air cleaner off the
induction pipe (where fitted).
Remove the exhaust pipe.
Disconnect the electric horn leads.
Disconnect the alternator leads from the
rectifier bracket and swing the rectifier clear.
Disconnect the distributor low tension lead.
Remove the carburetter tops complete with
slides.
Remove the rear chain.
Disconnect the clutch cable.
Remove the footrest bar.
Remove the bottom rear engine bolt.
Support the engine on a suitable box or
wood block.
Raise the centre stand and remove the
spring.
Loosen the bottom gearbox nuts and swing
the lower engine plates down.
Remove the front engine plates, horn and
stand.
Lift the engine out of the frame.
2. Removal of the Gear Box
Remove the engine sprocket and clutch
(Section C., Subsections 26 and 29).
Remove the rear half of the primary
chaincase by removing three socket screws and
the chain tensioner pivot.
The gearbox can now be withdrawn from the
back of the crankcase after unscrewing the four
nuts which secure it.
3. Dismantling the Crankcase
Drain the oil tank by removing the drain
plug.
Having removed the engine from the frame
as described in Subsection 1, dismantle the
heads, barrels, pistons, timing gear, magneto,
etc., as described in Section C.
Remove the gearbox as described in
Subsection 2.
Remove the two hexagon-headed plugs on
the driving side of the crankcase just below the
cylinder base.
On no account must these plugs be disturbed
on early models, unless the driving side cylinder
has been, or is to be, lifted, because they cannot
be tightened without holding the nuts inside.
Later models do not have internal nuts, the holes
in the crankcase being tapped and the plugs,
which have slotted hexagon heads, screw into
them.
Access can now be obtained through the plug
holes to two screws holding the two halves of
the crankcase together which must be removed.
Remove three nuts in the timing chest, two
nuts on the driving side crankcase, two loose
studs through the bottom of the crankcase and
two loose studs through the back of the oil tank.
(The other studs have already been removed to
take the engine out of the frame.)
