Table 1: Hydraulic and brake hoses
Note:
A: The design life of hydraulic hoses is subject to the level of wear and tear/usage and also
factors like harsh climate. It is recommended that they are reviewed periodically (i.e., yearly)
and typically replaced after ten years of operation if necessary.
B: The maximum oil pressure of the hydraulic system is 3,000 psi.
C: If there is a
valve chest fit to the MechFiber machine, it is essential to connect the valve
chest hydraulic feed and return pipes correctly. The return pipe is not designed to take the
hydraulic pressure normally seen in the valve chest feed pipe, and so seals and/or the valve
chest itself may be damaged if oil flows in the wrong direction through the chest. Typically, the
hydraulic return pipe on the valve chest is fitted with a one-way flow valve to prevent oil from
being fed to the valve chest in the wrong direction. This is identifiable as a steel connection on
the end of the pipe with an arrow stamped on its side to indicate the direction of oil flow through
it. Oil flows into the valve chest through holes marked P (Pressure) and out through holes
marked T (Tank), see Figure 5 below.
(The valve chest is set up for open-centre hydraulics. If the tractor has an alternative hydraulic
system [other than open-centre], then contact should be made with the tractor agent. To alter
to closed-centre hydraulics, there is a plug that can be fitted to the spool valve block and is
available from KEENAN on request.)
