end of the pushrod. It flows down the push rod
into the cam tunnel where it lubricates the cams
and tappets and thence into the timing chest,
lubricating the timing chains. There are small
holes from the cam tunnels through the cylinder
walls for the purpose of lubricating the skirts of
the pistons.
Both pumps are double acting, one side of
the feed pump supplying the big ends only and
the other side the rockers and valve gear. In a
similar manner one side of the return pump
pumps the big end oil back to the tank from the
crankcase and the other side the valve gear oil
back to the tank from the timing chest.
A spring loaded relief valve controls the
pressure of the oil to the valve rocker gear
which is through external pipes.
A gauze strainer is provided for the feed oil
leaving the tank and there is a large capacity felt
filter in the feed to the big ends. An aluminium
cylinder is fitted over the fixing stud inside the
filter element to reduce the volume of oil
required to fill the filter after it has been
dismantled for cleaning and to ensure the rapid
flow of oil to the big ends.
17.
Breather
The efficient operation of the breather is of
paramount importance to the performance of the
engine as it acts as a non-return valve between
the crankcase and the outside atmosphere,
causing a partial vacuum in the crankcase and
rocker boxes which prevents the passage of oil
into the cylinders and consequent smoking and
oiling of the plugs.
The breather is located on the driving side of
the crankcase and consists of a small housing
attached to the crankcase by three screws and
having a short rubber tube with flattened end,
which acts as a non-return valve.
On some models the housing contains two
pen-steel discs covering two holes drilled in the
crankcase. Accurate seating of the discs is
ensured by a pen-steel plate held between the
breather body and the crankcase.
18.
Gearbox
The gearbox is bolted on to the back of the
crankcase and has four speeds, which are foot
controlled, and a patented neutral finder. All
gears are in constant mesh, changes being
effected by robust dog clutches. (See Section
E).
The standard gear ratios are as follows :-
......
Solo Sidecar
Bottom Gear
... ... 12.05 13.55
Second Gear ........ ... ... 7.87
8.85
Third Gear ........... ... ... 5.63
6.34
Top Gear .............. ... ... 4.33
4.88
19.
Clutch
The clutch has six pressure plates and five
friction plates, including the sprocket which is
lined on both sides with friction material. The
other friction plates have Klinger inserts which
give smooth operation and freedom from
slipping in the presence of oil.
