TRACK AND SPROCKET
CARRIER, UNIVERSAL, MARK I * ITEM 6*
(Instructive - For immediate application)
It has come to notice that difficulty has been experienced, and in
some instances sprockets have been damaged as a result of "Crowding"
of the track following the installation of new components.
Some "Crowding" of the track will occur in all instances of complete
track and sprocket installation. It is to be overcome by installing
an extra link in the track until such time as both track and sprocket
have been "run in". This will take between 50 and 100 miles and
during this period the vehicle must be operated carefully, short
turns being particularly avoided wherever possible.
Proper meshing of the track and sprocket may be determined by close
inspection at the initial point of contact of the track on the sprock-
et when the vehicle is driven forward at as slow a pace as possible.
Attention is also drawn to paragraph 7, page 186, of "Manual of Dri-
ving and Maintenance for Mechanical Vehicles (Tracked) 1939" which
deals with the subject "New Tracks".
