'SS{S. Smith}' FRONT AXLE CONTROL.

Herewith we send N.Sch.2635 shewing the
front axle control and shock damper for 'SS{S. Smith}' which has been
designed to meet the difficulties raised by the four fixed
engine feet.

We have had to shorten the lever to approx.
11.625", but we believe that this will work satisfactorily.
The connecting rod is slightly shortened compared with standard.

It will be seen that we have slightly increased
the inner ball bearing. If it were possible to knock this
bearing out before undoing the nut retaining the lever it would
be possible to use a std. box spanner, but if not it is
suggested that the bearing could be pushed off by means of this
nut, in which case a special set spanner would be required.

Information as to the application of central
lubrication will follow later.
