The order o f assembly i s as follows: Sleeve, engine sprocket, slider, spring, collar
and nut. The nut should be screwed home with the box spanner in the same

The frame with swinging arm suspension was f i r s t fitted t o the Tiger models i n 1954,
and extended t o the rest of the range in 1955. In addition t o the other changes
this frame also employs a different method of gearbox mounting, but the actual
shafts and gears are identical. A stronger crankshaft and larger timing side main

during the 1955 season and is now fitted t o ail models except the Thunderbird.

The machine should be prepared in the usual manner by fitting stronger f o k springs,
a smaller engine sprocket and stronger springs and hump stops t o the Girling
rear suspension units.
!
it
is somewhat difficult t o compress the stronger suspension unit springs, and
it
is
suggested that if there i s a local Girling agent, he should be entrusted with the job.
I
For the guidance of those who do not live within easy reach of a Girling agent, the
I
procedure is as follows: Depress the top dust cover and remove the spring retainers.
I
The t o p dust cover, main spring and bottom dust cover may now be lifted off.
Slide the rubber bump stop down the damper piston rod and fit the halves o f t h e
1
bump stop w i t h the point of the cone facing upwards, taking care t o tighten the
1
four Allen screws evenly. Smear the new spring w i t h high melting point grease.

t o the unit and replace the split spring retainer.
