INTRODUCTION

TASK-29-11-69-99F-801-A01

1. General

A. This CMM is prepared in accordance with Air Transport Association (ATA) iSpec 2200. Inaccordance with this specification, the CMM is divided into the Sections given in the Table oContents.

B. Refer to the Table of Contents for the page locations of the Sections of this CMM.

TASK-29-11-69-99F-802-A01

2. Manual Use

A. The instructions in this CMM are arranged so that the operator can overhaul the assembly

removed from service and, by use of the recommended procedures, make the unitserviceable.

B. All weights and measures given in this CMM are in SI units with the equivalent imperial unitin parenthesis.

TASK-29-11-69-99F-803-A01

3. Maintenance Task Oriented Support System

A. A Maintenance Task Oriented Support System (MTOSS) is used for Electronic DataProcessing of the Maintenance Data in this CMM.

NOTE: For more data on MTOSS, refer to CMM Section 2-5-3 in ATA iSpec 2200.

B. An MTOSS number has seven elements. The first five elements must be used for each Tasand Subtask. The sixth and seventh elements are used when necessary. This CMM usessix of the seven elements. These elements are used as follows:

(1) Element No. 1, 2 and 3 are the Chapter, Section and Subject numbers (29-11-69 forthis CMM).

(2) Element No. 4 shows the maintenance function of the Task or Subtask.

NOTE: For more data on maintenance function codes, refer to CMM Section 2-5-3in ATA iSpec 2200.

(a) Maintenance function code 990 is expanded as follows in this CMM:

1 99A is used to identify tables

2 99B is used to identify illustrations

3 99C is used to identify front matter for Page Blocks or Tasks

4 99D is used to identify access

5 99E is used to identify references

6 99F is used to identify general/introduction

(b) Maintenance function code 940 is expanded as follows in this CMM:

1 94A is used to identify consumables and materials

2 94B is used to identify tools, fixtures and equipment

(3) Element No. 5 is used to make the Task or Subtask number different from other Tasksor Subtasks which have the same first four elements:

(a) Tasks are numbered from 801 thru 999.

(b) Subtasks are numbered from 001 thru 800.

(4) Element No. 6 is a three position alpha-numeric code which identifies differences inconfigurations or procedures or standard practices, etc.

(a) Most Tasks in this CMM will use A01 as the sixth element. This shows that theTask is used for all configurations with no differences.

(b) If the sixth element is S01, it shows that a Service Bulletin is related to the Task.

(5) Element No. 7 is a three position alpha-numeric code for customer use.

DESCRIPTION AND OPERATION

TASK-29-11-69-99C-801-A01

1. General

A. The system 1 and 2 hydraulic filter manifold is used to filter the supply hydraulic fluid fromthe aircraft pumps and ground power.

B. A general view of the system 1 and 2 hydraulic filter manifold is shown in Figure 1 (Refer toFigure 1 GRAPHIC-29-11-69-99B-801-A01).

C. A schematic diagram of the system 1 and 2 hydraulic filter manifold is shown in Figure 2(Refer to Figure 2 GRAPHIC-29-11-69-99B-802-A01).

D. A circuit diagram of the pressure switch is shown in Figure 3 (Refer to Figure 3 GRAPHIC29-11-69-99B-803-A01).

E. A circuit diagram of the pressure transducer is shown in Figure 4 (Refer to Figure 4GRAPHIC-29-11-69-99B-804-A01).

TASK-29-11-69-870-801-A01

2. Description

A. The primary component of the hydraulic filter manifold is a high strength aluminium forgingto which the filters and the other components are attached.

B. There are three filters, pressure, return and case drain. The filter bowls are attached to th

manifold by threads and are held when tightened by locking devices that engage withserrations on the filter bowl outer diameters. The locking devices prevent the filter bowlsfrom becoming loose during operation. The filter bowls are made to be removed andreplaced by hand, a knurled surface is used as an aid.

C. The pressure and return filter elements filter the hydraulic fluid to 5 microns absolute. Thecase drain filter element filters the hydraulic fluid to 15 microns absolute. When the filterelements become blocked, they cannot be cleaned or used again, they must be discarded

D. Each filter port in the manifold contains a shut-off valve. The shut-off valve is a spring loademechanism which prevents leakage of the hydraulic fluid from the manifold when the filterbowl is removed to replace a filter element. During operation, the shut-off valve is held opeby the filter element. When the filter bowl and the element are removed, the shut-off valveis closed by a spring.

E. The condition of the filter elements is shown by three differential pressure indicators (DPI).The three DPIs are the same. Each DPI is attached to the manifold by four screws and aclamp ring and is sealed by O ring seals and back-up rings. The DPI gives an indication ofincreasing differential pressure across the filter element because of an impending blockage.At a set pressure, a red pop-up button is operated and shows that the related filter element

must be replaced as soon as possible. Each DPI includes a thermal cut-out device. Thisprevents operation of the DPI at low temperatures when the viscosity of the hydraulic fluid ishigh.

F. A bypass relief valve is installed in the manifold and operates when the return filter elementis blocked. This prevents there from being too much pressure in the return line.

G. The engine driven pump (EDP) pressure inlet contains a check valve. A pressure switchadjacent to the EDP pressure inlet gives an electronic indication when the pressure reaches16548 kPa (2400 psi).

H. The AC motor pump (ACMP) pressure inlet contains a check valve. A pressure switch

adjacent to the ACMP pressure inlet gives an electronic indication when the pressurereaches 16548 kPa (2400 psi).

I. A pressure transducer is installed in the manifold. This gives an electronic indication of thehydraulic fluid pressure at the pressure outlet.

J. A system pressure relief valve is installed in the manifold between the pressure line and thereturn line. If there is too much pressure in the pressure line, the relief valve operates anddecreases the pressure through the return line.

K. The manifold also includes all the necessary unions for connection to the aircraft hydraulicsystem.

L. 2346H000-003 introduces filter kits that incorporate a new shut-off valve piston.

M. 2346H000-004 introduces a new manifold with revised positions for Ground ServicePressure Fitting and ACMP Pressure switch.

N. 2346H000-005 introduces a filter kit that includes a new pressure filter bowl.

O. 2346H000-006 introduces a new manifold and a new EDP pressure inlet check valve.

3. Operation

A. The hydraulic fluid in the aircraft pumps and ground power systems is filtered to 5 microns

absolute by the pressure and return filters. The hydraulic fluid which goes through the casdrain filter is filtered to 15 microns absolute. The condition of the filters is shown by thedifferential pressure indicators installed adjacent to the filters.

B. If there is too much pressure in the pressure line, the system pressure relief valve operateand the hydraulic fluid goes into the return line.

C. If the return filter element becomes blocked, the return bypass relief valve operates and thehydraulic fluid goes into the return line.

D. Non-return valves prevent flow in the opposite direction through the pressure lines.
