Washer Hoses, repairing
General information
A concept has been developed to facilitate the repair of washer hoses.
Various individual hose connectors, adaptors, Ethylene Propylene Diene Methylene (EPDM) rubber hoses and shrink tubing will be offered as replacement parts.
Part numbers Parts Catalog .
Repair parts will be available for both smooth and
corrugated hoses.
Smooth hoses, repairing
Smooth hoses with a diameter of 5 x 1 mm or 6 x 1 mm can be repaired with a EPDM repair hose section. - Trim and remove damaged sections of hose.
- Choose matching EPDM repair hose - 2 - and cable ties from Parts Catalog.
- Insert hose - 1 - and - 3 - into ends of EPDM repair hose - 2 - to a depth of at least 10 mm - arrows - .
- Secure cable ties - 1 - as illustrated.
Corrugated hoses, repairing
Special tools, testers and auxiliary items required
Hot air blower VAS 5179 or
Hot air blower V.A.G 1416/ or
Hot Air Gun VAS1978/14
Note:
Area to be repaired must but be under stress of
stretching or bending.
If damaged area is longer than 20 mm, a new
section of corrugated hose must be obtained, and two sets of adapters inserted using following the following procedure.
- Choose matching repair adapters - 2 - and - 3 - and appropriate shrink tubing from Parts Catalog.
- Carefully warm end of hose - 1 - .
- Insert repair adapter - 2 - into hose - 1 - , - arrow A - . - Carefully warm end of hose - 4 - .
- Insert repair adapter - 3 - into hose - 4 - , - arrow B - .
- Trim shrink tubing sections so that corrugated hose is covered a minimum of 20 mm - dimension x - .
- Slide shrink tubing over corrugated hose, attach adapters together and secure repair with shrink tubing.
