Honda CB750 FOUR: Assembly Guide
Instant adhesive
Tap wrench
In Stage 4, you were advised to cut a thread in the handlebar clamps using the screws
supplied. To make such tasks easier in the future, you can use a tap wrench and taps to
prepare the holes for the screws. For example, the type A screws used in Stage 4 are 2 x
6mm, so you would choose a 2mm tap to prepare the hole.
A tap wrench and two medium taps. These
are dedicated tools for cutting threads in
screw holes.
Insert the end of the tap into the hole
you want to thread and slowly turn the
wrench. The tap will screw itself into the
hole, cutting a thread as it goes. Make sure
you keep the tap straight as you turn it in.

Instant adhesive is very useful if you
need to repair any parts that have
been damaged. Standard superglue
or instant adhesive is prone to
drying slightly white, which can spoil
the appearance of your model, so it
is best to try and find one that is a
'low whitening' type.
Identify the correct size tap for the hole: it
should match the diameter of the screw.
Insert the tap into the hole in the wrench
and tighten it into place.

clamps using a tap and wrench, ready for a
screw to be fitted.
Screwdrivers and screws
During this series, the most frequently used screwdriver is the size 1 Phillips.
Always try to use the correct size of screwdriver, as using a larger or a smaller
one can damage the head of the screw, and possibly make it impossible to
tighten or remove.
Precision screwdriver sets often have a
label showing the size of each driver.
To check if a screwdriver is the right size
for a screw, insert it into the head and
gently turn it to the left and right. If the
driver is the wrong size for the screw,
it either won't fit into it or it will fit very
loosely. If so, try again with different size
drivers until you find one that fits correctly.
It's a good idea to have drivers of the same
size but with different grips, like the pairs
shown above, as they can be helpful for
different situations.

There are two types of screw used in this
series – the machine screw, which will
generally be referred to as just a 'screw',
and the self-tapping screw. The machine
screw is used for metal parts and the self-
tapping screw for plastic parts.
