Inspection of Hoses and Fittings for Leaks
Inspection of Hoses and Fittings for Leaks - Gen 5 DD15
- Ops - #7628
All hoses, lines and connection points should be inspected periodically. A good practice is to include the hoses, lines and connection point inspection as part of the pre-start inspection. Leaks are not only detrimental to mechanical operation, but they can also result in added expense caused by the need to replenish lost fluids.
Inspect hoses and fittings for leaks as follows:
Note: If any of the below conditions
exist, it may be necessary to take the vehicle to an authorized Detroit™
service outlet.
- Make a visual check for leaks at all engine-mounted lines and connections.
- Inspect all hoses for leaks, and check all fittings, clamps and ties carefully. Look for cover damage and/or indications of twisted, worn, crimped, brittle, cracked or leaking hoses and lines. Hoses with their outer cover worn through or with damaged metal reinforcements should be considered unfit for further use and replaced.
- Make sure hoses are not resting on or touching shafts, couplings, or heated surfaces including exhaust manifolds, sharp edges, or other obvious hazardous areas.
- Since all machinery vibrates and moves to a certain extent, clamps and ties can fatigue with age. To ensure continued proper support, inspect fasteners frequently and tighten or have them replaced as necessary.
- Take immediate corrective action for any loose or cracked fittings or ruptured or worn through hoses.
