    8.1 Operating pressure

    The uniform nominal value for the operating pressure is: pA = 8.5 bar (tolerance 0.2 bar).Measure the pressure only at an oil temperature of 80 - 90 C (= 176 - 194 F), imme-diately after shifting to 2nd gear (engine speed approx. 1500 rpm).

    Nominal value at idle speed (n approx. 500 - 600 rpm) pA 3.5 bar.

    Measuring points The operating pressure is usuallymeasured at the measuring point (fi-gure 1/1).

    If a measuring cover (figs. 2 and 3)is used, pressures which must cor-respond to the operating pressureare measured at the measuringpoints for the clutches resp. brakesDK, EK, PB, WP and SK.Fig. 2: Meas. points for DIWA.3Fig. 3: Meas. points for DIWA.3E

    Note! The WR oil pressure is cy-cled and therefore variable overtime, its amount in addition de-pending on the relevant operatingstate (during braking or rever-sing). Therefore, simple pressuremeasurements by means of pres-sure gauges are not adequate formore thorough troubleshooting.

    The measuring points TB, RBG and RBK are each pressurized with the higher ope-rating or converter pressure. Exceptions: The RBK pressure is set to 1. approx. 2.5 bar for converter pressure reduction WDA,2. max. approx. 2 bar for braking in 1st gear range (chapters 5.4 and 5.6).

    Danger! Connect pressure gauge, or change measuring cover, only with the en-gine stopped, otherwise hot oil may result in scalding!

    If the measuring points mentionedare not accessible, the operatingpressure can also be measured forDIWA.3 transmissions at the inter-mediate flange (if installed) of the oilfilter: If the pressure is measured before(4/1) or after (4/2) the filter, approx.0.5 bar must be added as flow resi-stance to obtain the value for theoperating pressure.Note! Only measure before the fil-ter if the filter element is clean!

    The working pressure can be set atthe threaded pin of the operatingpressure valve (5/1) - only possiblewith special screwdriver and socketwrench through the oil filler!If the required operating pressure isnot reached, check piping for leaka-ge and sealing gaps of the gearpump.

    8.2 Converter pressure

    The converter pressure must be: pW 2 bar at an oil temperature toil of approx. 80 - 90 C (= 176 - 194 F), with forwardgear engaged, engine at idle speed (500 50 rpm) and parking brake applied.If this value is not reached, converter sealing must be improved.

    Measuring pointUsually, the converter pressure ismeasured at measuring point (6/2).

    Converter pressure with WDA de-activationAt toil of = 80 - 90 C (= 176 - 194 F),the converter pressure must be0,7 < pW < 2 bar

    9.1 Engine idle speed

    In particular in conjunction with electronic engine control units, it is frequently not pos-sible to set the idle speed n in a simple manner. In addition, the settings are system-dependent (guideline: n approx. 500 - 600 rpm with warm engine). On the otherhand, the idle speed must not be too high, because the input clutch, for example, willnot close: n 850 rpm (for gas engine: n 1000 rpm). During a function check, the speed can be measured by means of the diagnostic pro-gram, for example.Note! If the idle speed must be changed, contact the bus manufacturer, if requi-red.

    9.2 Test: load transmitter signals as function of accelerator pe-dal position

    The life of DIWA transmissions to a considerable extent depends on proper pressuresin front of the disk clutches and brakes during shifting. Along with the input and outputspeeds, the motor torque is important, which to a great extent is in turn affected bythe accelerator pedal position resp. the appropriate load levels L0 - L6 (or L0 - L7).The associated electronic signals are provided to the transmission in a different man-ner dependent on the engine control system.

    The following settings can be checked in a relatively simple manner with the bus stop-ped by means of the diagnostic program:1. Load level L0 = "idle", accelerator pedal completely released. 2. Load level L6 = "full load", accelerator depressed to the stop (first, if any). Depend-

    ent on the bus design, this accelerator pedal position may also be defined as L7 ="kickdown", which is indicated by the diagnostic system.

    3. Inf installed: load level L7 = "kickdown", accelerator pedal depressed beyond thefirst and to the end stop against greater resistance.

    4. Gradually depress the accelerator pedal from idle to full load and check that the"partial load" signals L2 to L5 are also displayed by the diagnostic system.

    Note! For an accurate check of the load transmitter partial load signals as func-tion of the accelerator pedal travel, documents from the bus manufacturer arerequired.

    Danger! When settings are made with the bus stopped, apply the parking braketo prevent unintended rolling of the vehicle!

    If the diagnostic system indicates load levels that do not correspond to the acceleratorpedal position, the following causes for faults may exist, apart from cable and connec-tor defects:1. Setting of accelerator pedal stops (idle, full load, kickdown, if installed). 2. With a VDO or Voith load transmitter: connection between load transmitter and in-

    jection pump, see figures 7 and 8 on next page. 3. With electronic engine control units: connection between accelerator pedal and

    load transmitter (setpoint switch), see figure 9 on next page. 4. Wrong control unit with data of the wrong load transmitter type (indicated by dia-

    gnostic system).

    If the injection pump lever the load transmitter lever mustis in full load position be on the full load mark too!

    Otherwise, move the fastening with the link accordingly.

    Then recheck the setting in 0 load position!

    Note! the adjustment angles of the levers of injection pump and load transmit-ter must be in proportion to each other! For example, if the injection pump leveris moved by 1/3 of the angle between 0 and full load, the load transmitter levermust also be move by 1/3 of its angle between 0 and full load!

    9.3 Test: rated engine torque as function of load stage or enginespeed

    It may be necessary to determine the maximum possible engine torques in bus ope-ration. Indirectly, they can be determined in a relatively simple manner by speedmeasurements in the so-called stall point - e.g. by means of the diagnostic program.

    First of all pay attention:Danger! Apply parking brake to prevent unintentional bus movement!After that as example for full load operation (= load level L6):1. engage forward gear, 2. depress accelerator pedal to the full load stop, 3. enter the measured engine speed N1 (= stall speed) in the diagram below

    (figure 10). The intersection with the appropriate pump characteristic of the trans-mission - for pump design, check the transmission nameplate, for example -shows the maximum possible engine torque with the bus stopped.Note! The latter torque may deviate significantly from the maximum possibleengine torque while driving with electronic engine control units. These testsare performed during acceptance protocol measurements.

  • SAFETY NOTICE

    Companies repairing ZF units are responsible for theirown work safety.

    To avoid injury to personnel and damage to pro-ducts, all safety regulations and legal requirementswhich apply to repair and maintenance work mustbe adhered to.Before starting work, mechanics must familiarizethemselves with these regulations.

    Personnel required to carry out repairs on ZF productsmust receive appropriate training in advance. It is theresponsibility of each company to ensure that theirrepair staff is properly trained.

    The following safety instructions appear in thismanual:

    NOTERefers to special processes, techniques, data, useof auxiliary equipment, etc.

    CAUTIONThis is used when incorrect, unprofessionalworking practices could damage the product.

    DANGERThis is used when lack of care could lead to personal injury or death.

    GENERAL INFORMATION

    Read this manual carefully before starting any tests orrepair work.

    CAUTIONPictures, drawings and components do not alwaysrepresent the original object, but are used to illustrateworking procedures.Pictures, drawings and components are not to scale.Conclusions about size and weight should not bedrawn (even within a complete illustration).Always follow the working steps as described in thetext.

    After completion of repair work and testing, skilled staffmust satisfy themselves that the product is functioningcorrectly.

    THREATS TO THE ENVIRONMENT !Lubricants and cleaning agents must not be allowedto enter the soil, ground water or sewage system. Ask your local environment agency for

    safety information on the relevant products and adhere to their requirements.

    Collect used oil in a suitably large container. Dispose of used oil, dirty filters, lubricants

    and cleaning agents in accordance withenvironmental protection guidelines.

    When working with lubricants and cleaningagents always refer to the manufacturers instructions.

    CAUTIONThe transmission must NOT be hung by the inputshaft NOR by the output flange.

    Important information HP 502 C / HP 592 C / HP 602 C

  • 7In case of doubt always turn to the relevant depart-ment within ZF After-Sales Services for advice.All work on transmissions is to be performed expertlyand under clean conditions.Use specified tools to dismantle and assemble trans-missions.

    After removing the transmission from the vehicle, clean thoroughly with a suitable cleaning agent beforeopening.Pay particular attention to the projections and recessesof housings and covers when cleaning.Parts joined with Loctite are easier to separate if warmed with a fan heater.

    CLEANING PARTS

    Remove remains of old gaskets on all seal-faces.Carefully remove burrs or similar patches of roughnessusing an oil-stone.

    Lube bores and grooves must be free of anti-corrosionagents and foreign matter; check for perfect passage.

    Carefully cover opened transmissions to prevent foreignmatter from entering.

    REUSING PARTS

    Parts such as ball or roller bearings, multi-discs, thrustwashers etc., must be inspected by a competent person,who should decide whether or not they can be re-used.Replace parts which are damaged or have suffered fromexcessive wear.

    GASKETS, LOCKING PLATES

    Parts which cannot be removed without being damagedmust always be replaced with new parts (e.g. gasketsand locking plates).

    SHAFT SEALS

    Always change shaft seals with rough, ripped or hardened packing washers. Seal contact surfaces mustbe totally clean and in perfect condition.

    REWORKING

    Rework may be carried out on seal contact surfacesusing plunge-cut grinding only, never use an emerycloth. Ensure that there are no traces of grinding or riffling.

    If rework is needed on distance washers, shims etc.because of clearance settings, ensure that the reworkedareas contain no face runout and have the same surfacequality.

    TRANSMISSION ASSEMBLY

    Find a clean site to assemble the transmission. Gasketsare installed without the use of sealing compound orgrease. When measuring silicon-coated gaskets, takecare not to include the silicon layer in the measure-ment.During assembly, comply with all adjustment data,checking data and tightening torques in the RepairManual.

    HP 502 C / HP 592 C / HP 602 C Instructions for repairs

  • 8BEARINGS

    If bearings are mounted in heated condition, they are tobe heated evenly (e.g. heating cabinet).Temperature should be at ca. 85 C and must not exceed120 C. Each mounted bearing must be oiled with operating oil.

    SEALING

    If a specific sealing agent* is to be used for sealing,comply with the manufacturers directions for use.Apply a thin layer of sealing agent to the surfaces andspread evenly. Do not allow sealing to enter oil ductsand bores. On oil-carrying ducts and bores, wipe off thesealing agent on the surfaces to be sealed near aperturesto ensure that no sealing agent enters the oil feeds whenthe surfaces are sealed.

    SHAFT SEALS

    a) Apply a light coat of sealing agent* on outer edge ofshaft seals with steel surround.

    b) Never apply sealing agent to shaft seals with rubber surround, but apply a thin coat of Vaseline8420 to the outer edge or wet with a lubricant, e.g. awater-soluble, concentrated washing-up liquid (e.g.Pril, Coin, Palmolive).

    c) Shaft seals with steel and rubber surrounds should betreated on the outer edge of the rubber surround asdescribed above in section b).

    d) Dual shaft seals have two sealinglips. The dust-proof sealing lip (X)must face outwards.

    e) Fill the gap between the sealinglips so it is 60% filled with grease (e.g. produced by Aral such as Aralub HL2 or by DEA such asSpectron FO 20).

    f) If possible, heat shaft seal bores to between 40 and50 C (makes fitting easier). Press the seal shaft withmounting or faceplate onto the relevant installationdepth plan.

    RETAINING AGENTS

    Retaining agents* may only be used in places as specified in the parts list.Always comply with manufacturers directions for usewhen using retaining agents (e.g. Loctite).During assembly, comply with all adjustment data,checking data and tightening torques.

    TRANSMISSION OIL

    After completing repairs, fill transmissions with trans-mission oil. For the procedure and approved oils, referto the transmission operating manual and List of Lubri-cants TE-ML (refer to identification plate) which areavailable from any ZF After-Sales Service Point. Afterfilling the transmission with oil, tighten the screw plugsat the oil filling point and the oil overflow to the speci-fied torques.
