Hydraulic Hose Repair Explained

How It’s Done

Curious about the hydraulic hose repairs performed at L & R Transmissions in Winston-Salem, NC? Here’s a quick explanation of how our team of ASE Certified technicians handles damaged hoses and creates new assemblies.

Remember that if a hydraulic hose is damaged, its function and safety are compromised. A pinched hose may have restricted flow which could lead to a burst. Working with hydraulic hoses can be dangerous, as they are prone to whipping when seals suddenly break. That’s why it’s best to leave repairs to the professionals! Don’t try hydraulic hose repairs or installs at home without the guidance of an expert!

1. We select the correct hose & fittings. BSP, JIC, ORFS, Metric, and Flange are a few common types of fittings which may be easily confused, so we carefully follow manufacturer recommendations to ensure our hydraulic hose repairs meet standards.
2. We measure & cut the hose. Industry standards measure hoses from cone to cone to ensure proper fitting and a successful seal. How a hose is measured may vary based on the type of fitting used and manufacturer recommendations, so our technicians check on the details for an exact measurement before cutting a new hose.
3. Next, a special machine must be used to cut the hose cleanly and accurately. Using improper tools will result in an asymmetric cut that won’t create a proper seal.
4. Before installing the new hose assembly, the orientation of the fittings is carefully set according to the application in the vehicle. We want to make sure the ends are pointing in the right direction for their connections.
5. The final step before install is called swaging. Special equipment is used to crimp the hose closed around the fitting, but extreme care is given to apply the proper pressure for the size and type of hydraulic hose. Over crimping will restrict flow and create blockages. Under crimping won’t create the necessary compression seal, which will lead to leaks, blistering, and bursts.

After these careful steps of hydraulic hose repair, our technicians are ready to install replacements into the vehicle. We only put parts into a vehicle that we are sure will do the job right, so we give care to the assembly process long before the hose is installed into the vehicle.
