The pictorial parts
list of the English Neracar Model A
The goal of setting up the
pictorial parts list is to record and show what a British Model A
Neracar and its composing parts look like. It is intended to help
other owners to restore their motor bike to a condition as original
as possible. As there is always a trade off between the amount of
work and the technical limitations to set up such a database on the
one hand and the potential benefit to the user on the other hand, I
drafted a set of guidelines which outline the limitations and
The pictorial parts
list consists of photographs on which, where applicable,
dimensions are drawn. This will save me time by not going
through an elaborate process of creating technical drawings and
it will allow those users, who are not skilled in reading
technical drawings, to see what a particular part looks like and
what its dimensions are. The photograph with dimensions should
be detailed enough to enable a skilled amateur to make a replica
of the part.
- Dimensions will not be
added to photographs of every part, but just to those which are
likely to be replicated, like e.g. the rear stand, head light,
etc. Not many people will make a replica of the crank case, so
adding all individual dimensions in that case is cumbersome and
probably useless. Photographs
and dimensions should give enough information to be able to
acquire the correct item however.
- The parts list is made
while restoring the bike and is not the primary goal; the
primary goal is to restore my bike to its original condition.
This means that I will make records of all parts which are
dissembled, but I will not unnecessarily dissemble units just
for the sake of creating drawings. In practice however, the vast
majority of the parts will be included. Entries from other users
- Some dimensions are
difficult to measure; in those cases where they are not
critical, they can be approximated by scaling.
- Materials will be added
insofar it is possible; the reader should know if the used
material is steel, brass or bakelite. But I will e.g. not be
capable of distinguishing between phosphor bronze and lead
- Feed back is highly
appreciated and can lead to improving and updating the parts
- Although utmost care
with be taken, I can not guarantee that all photographed parts
are original. In obvious cases, like the front stand which I
made a replica of myself, this will be clearly indicated on the
- If you need any
information which is currently lacking, please let me know.
- Some parts have been
photographed before restoration, because it is difficult to take
contrast photographs when parts are spayed in shiny black.
Scratches and rust will be helpful in focusing and give contrast
to the picture.
- Where applicable, a
brief description of the part is added.
- For the sake of
clarity, dimensions and remarks are spread over several views;
the drawings of a part have to be considered a set.
- Drawings are made using
Power Point; as PP allows for just discrete steps, centre lines
may be a bit off.
- When taking
photographs, different sections of a part are seen at different
angles, so we are not dealing here with a pure multi view
orthographic projection, generally used in technical drawings.
This limits the accuracy of scaling in case dimensions are not
- In some cases,
additional photographs are added to show the orientation of a
particular part in relation to the surrounding area, e.g. the
front stand which can easily interfere with the muffler, the
foot brake lever and the engine’s bottom cover plate. In
general, a small selection of overview pictures are shown. Often
times, more photographs are available. If you need more details,
- The disadvantage of
this approach is that it has no cross sections (I won’t go that
far just for the sake of this pictorial), so uncommon ways of
presenting some dimensions can be used.
- Where possible, I’ll
stick to the assemblies (clustering), terminology and part
numbers Neracar used in their parts list.
Besides the Technical Drawings,
I used my common sense in determining which part bears which
number. The terms ‘left view’,
‘right view’, ‘front view’ and ‘rear view’ refer to the left,
right, front and rear of the bike. A right view e.g. is a
photograph of the part, taken from the right hand side of the bike.
Parts are photographed upside up; where a part for practical
reasons is photographed upside down, this will be clearly
- Dimensions of rough
parts, like the rear stand, will be measured in fractional
inches; those of machined parts will be measured in decimal
inches. As dimensions are taken from parts that may show wear,
dimensions of replicated parts may need correction for a correct
fit. Tolerances are not given.
- Readers are encouraged
to supply any missing information, in order to increase
completeness. Where ‘TBD’ (To Be Determined) is mentioned,
dimensions still have to be measured and entered.
- Although the utmost
care has been taken, correctness cannot be guaranteed. Please
report any errors you may come across.
- Upon request,
photographs can be made available in high resolution *.emf
Remark: For wire diameters and metal sheet thickness inch dimensions
It would have been better for smaller dimensions to have them in
