1918 Henderson ‘Z Model’

1918 Z model Henderson

The frame here is from 1918 and pre-Excelsior changes.  It has the shorter footboards and was not fitted with the Excelsior brake system.  As such, the frame would have been painted Henderson blue.

The engine is not the original but is a 1918 Z model which would still make the whole bike a veteran one in Australia. The engine has almost been completely restored, timed and started with the present carburettor.

The big ends and main bearings have been white metalled and line bored.  The clutch and thrust bearings are new.  Cast iron pistons with new rings have been fitted.  Eventually the cast iron pistons and valves may need replacing.

The magneto has been professionally rewired.

All nuts and bolts are either original or replaced with original looking ones.  A number of threads have been recoiled back to original sizes.

The areas that will need attention are re-sleeving the inlet rocker arms and overhauling the Schebler carburettor.

A new chain will need to be fitted.

The gear and clutch lever need replacing but these are available in Australia and Germany.  Petrol and oil caps, petrol and oil pipes, taps, control fittings and clips, cables are also missing.

The wheels have been fitted with Timken bearings and need replacing.  New axles are needed for both wheels.

This could be fitted with an Excelsior brake system which has an internal brake connected to the clutch leaver.  Otherwise the pre-Excelsior brake system could be used.

Various spare parts are included with the project.
