DS 19 OPERATION No. 174-3 Repair of a flexible feed pipe or a suspension return pipe. Op. DS 174-3 123
TOOLS
NOTE - This repair can be carried out by fitting a sleeve on the pipe system (petrol feed or suspension return) or
by replacing one of the unions (return).
If two sleeves have to be fitted on the same pipe, they must be about 800 mm apart in order to retain the
flexibility of the pipe assembly.
The flexible pipes and Rilsan unions are sold by our Spare Parts Department.

1 After trimming the pipes, remove the polish from the ends of the pipes for a length of approximately 90 mm or
remove the polish from the union outlets using No. 600 abrasive paper.
2 Carefully remove all grease from the rubbed down ends, with trichlorethylene, also on the sleeve.
3 Heat the Rilsan paste in a bath and bring it to a temperature of 60° C. Do not heat beyond this temperature.
This operation is essential to reduce the hardening period.
4 IMPORTANT NOTE - Rilsan paste attacks the skin and must not be touched with the fingers.
Rilsan paste destroys the bristles of nylon or Rilsan brushes; use a wooden stick or spatula.
a) Smear the ground ends of the pipes and the inside of the unions with paste.
b) Let the parts dry for a few minutes.
c) Insert the ends of the pipes or the union outlets in the sleeves.
d) Leave the assembly for 3 to 4 hours to dry before using the repaired pipe.
