Carefully inspect all Hydraulic hose fitting at common intervals to make sure airworthiness. Investigate any proof of fluid great loss or leaks. look at metallic tubes for leaks, loose anchorage, scratches, kinks, or other damage. Inspect fittings and connections for leakage, looseness, cracks, burrs, or other damage. Replace or fix defective elements. be good the hoses do not chafe in opposition to one an extra and therefore are properly secured and clamped.
When inspection exhibits hydraulic hose to acquire broken or defective replace the whole collection or, once the broken part is localized, a fix part may maybe be inserted. In replacing jet hose, usually use tubing within precisely the exact sizing and materials since the reliable line. take advantage of the aged tubing getting a theme when bending the brand new tube, unless it is as well significantly damaged, by which circumstance a theme could possibly be developed from gentle metal wire. gentle aluminum tubing below half-inch outside diameter may maybe be bent by hand. For all other tubing use an acceptable hand or energy tube-bending tool. Bend tubing very carefully to refrain from too much flattening, kinking, or wrinkling. merely a little amount of flattening in bends is acceptable, but do not exceed 75 % inside the reliable outside diameter. too much flattening will need about fatigue failure inside the hydraulic tube. When installing the substitute tubing collection it up properly using the mating element to ensure that it is not forced into alignment by tightening inside the coupling nuts.
The tubing is then flared utilizing the precise 37-degree aviation flare forming unit to the sizing of tubing and sort of fitting. A double flare is utilized on gentle aluminum tubing 3/8-inch outside diameter and under, with one another with just one flare on all other tubing. In producing the connections, use hydraulic fluid getting a lubricant after which tighten. over tightening will harm the tube or fitting, which may maybe take about a failure. Under-tightening may maybe take about leakage which could carry out result within a plan failure.
Minor dents and scratches in tubing may maybe be repaired. Scratches or nicks not deeper than 10 % inside the wall thickness in aluminum alloy tubing, which could be not within your heel of the bend, may maybe be repaired by burnishing with hand tools. Replace lines with serious die marks, seams, or splits within your tube. Any crack or deformity within a flare is unacceptable and take about for rejection. A dent much lower than twenty % inside the tube diameter is not objectionable unless it is within your heel of the bend. A severely-damaged collection must acquire replaced; however, it may maybe be repaired by slicing out the broken part and inserting a tube part within precisely the exact sizing and material. Flare equally ends inside the undamaged and substitute tube sections and make the interconnection by utilizing common unions, sleeves, and tube nuts. once the broken portion is short enough, omit the insert tube and fix by utilizing one union and two sets of interconnection hose fittings.
When substitute of versatile hose is necessary, use precisely the exact type, size, element number, and period of your time of hose since the collection to acquire replaced. look at TSO requirements. once the substitute of the hose using a swaged-end sort fitting is necessary, acquire new hydraulic hose assemblies inside the precise sizing and composition. particular artificial oils contact for just about any specifically compounded artificial rubber hose, that is compatible. Refer to the jet manufacturer's help information and details to the precise element amount to the substitute hose. once the fittings on each and every carry out are inside the precise sort or sleeve type, a substitute may maybe be fabricated. past to slicing new versatile cable tv braided hose to the precise size, tape the hose tightly with masking tape and minimize within your center inside the masking tape to refrain from fraying.
The utilization of the mandrel will refrain from slicing the within inside the Hydraulic hose fittings when inserting the fittings. set up hose assemblies devoid of twisting. A hose should really not be stretched tight in between two fittings as this could carry out take about overstressing and eventual failure. The period of your time of hose must acquire adequate to provide about 5 to 8 % slack. refrain from tight bends in flex lines as they may maybe carry out take about failure. certainly not exceed the minimal bend radii.
