Most hydraulic hose fittings are made to handle pressure from different types of abuse and tolerate heavy work. They are designed to serve and last for a long time but a time comes when they succumb to such pressures. This is the case when fittings break down and such a situation calls for immediate replacement to avoid more damage to the equipment and restore its normal functioning. Hydraulic fitting replacement is not a complicated affair that needs any mechanical or plumbing skills. Simple steps will help you replace the hose fittings and save you some bucks for your personal use.
Basic Materials Needed
Rule number one is having the right tools for the job. You will need new hydraulic hose fittings for replacement, chains, clamps, a pipe wrench for loosening and tightening the ends, buckets, rags, a multi-purpose wrench, working gloves, working cloths preferably an overall, and protective eye glasses.
Diagnose the Main Problem
A visual inspection of the hydraulic pump is necessary to determine the level of damage. You will need to locate all the damaged fittings and the leaking hoses by laying the hose on the ground and surveying it carefully. Mark the areas that have issues and get ready for your repair tour.
Relieve Pressure on Hydraulic Cylinders
You need to relieve pressure on the hydraulic cylinders before you attempt any repair move on the hose fitting. This will prevent any blow-out situations.
Dismantle Components of the Hose
Remove hose components such as clamps, guards, and the housing unit in order to replace your new hose. Be keen to note the location each component as you un-mount the unit to avoid any confusions when reassembling. You may consider taking a picture or labelling the units as you remove if you are not sure of the process.
Remove Hose Fittings
Two wrenches will be needed since most hose fittings swivel when the hydraulic pump system is powered on. The swivelling part of the hose fittings has two couplings. Clamp one wrench on one side of the couplings to acquire a steady grip and another wrench on the opposite side. Loosen the fittings and gently pull them out.
Clean well and Replace New Fittings
Use a rag to clean the fittings and keep them free from any dirt or debris. Use your pictures to patiently reinstall new fittings and other components of the hose. The clamps and guards must be in their correct positions.
More important, when dealing with cylinders, the cylinder pins should be properly returned before replacing the snaps rings that hold the pins in place.
