A heavy wall tubing and multi-wire hose network carries the hydraulic oil from the reservoir to the pumps and valves
and then to cylinders and motors and finally back to the reservoir.
Operating pressure of the hydraulic system varies from model to model. For your loader, consult the Hydraulic
Pressure Warning Sheet in this manual.
Replace any tubelines which are bent or have become flat. There will be a restriction of fluid flow which will make
hydraulic action slow and cause heat. Replace hoses which show signs of wear, damage, or weather-cracked rubber.
When making repairs on hydraulic system keep all parts clean and remove all dirt from the area
before you disassembly Use caps and plugs to keep dirt out of tubelines and openings.
PIPE THREAD SEALER
The main causes of air being introduced into a hydraulic system are loose connections and fittings. This not only
creates aeration in the fluid but also provides the risk of contamination entering the fluid and components with the air.
The easiest way to effectively reduce and possibly eliminate this problem is to use an adequate pipe thread sealer at
all connections and fittings.
While other pipe thread sealers may meet specifications, the methods which Barko uses are Teflon tape, and Locktite
Teflon Thread Sealer.
The sealer will form a flexible, non-hardening seal that can be easily broken at any time without stripping the threads
or damaging the pipes or fittings. It will also provide a non-shrinking bond that will inhibit rust or corrosion in the
threads and will not gall, seize, or block the threads.
APPLICATION
The pipe thread sealer is intended for use on threaded steel pipe in fixed installations. It can be easily applied by the
tube it comes in. This sealer is intended for use with petroleum fluids only. Apply sealer sparingly and leave the first
two threads near the end of the pipe or fitting bare.
Barko recommends the use of pipe thread sealer on all exterior pipe plug threads and pipe fittings.
