2 REPAIR INSTRUCTIONS for the ZF PLANETARY STEERING AXLE APL-R 715 I M P O R T A N T R E F E R E N C E : The extreme variety of ZF-unit requires that the disassembly- and assembly instructions are limited to a frequently sold ZF-series unit. The further technical development of the ZF-units as well as extension- and execution options can require deviating operations which can be performed by qualified expert staff without any problem with the aid of the perspective representations in the respective spare parts lists. The present disassembly- and assembly instructions represent the construction state of a ZF-series unit at the time of the preparation of these instructions. The ZF Passau GmbH reserves the right to substitute the present disassembly- and assembly instructions at any time by a successor edition without special notice. Upon request, the ZF Passau will inform you on the actual and binding edition. ATTENTION: For the installation and starting up of the unit, observe the instructions of the vehicle manufacturer!

7 PREFACE This documentation has been developed for skilled staff trained by the ZF Passau for the repair and maintenance works on ZF-units. Documented is a ZF-serial product representing the design state at the time of the edition. However, due to further technical developments of the product, the repair of the unit at your disposal could require different steps as well as different adjustments and testing specifications. Therefore, we recommend to commit your ZF-product to foremen and technicians whose practical and theoretical training is permanently updated in our after-sales service school. The service stations established world-wide by the Zahnradfabrik Friedrichshafen are offering to you: 1. Continuously trained staff 2. Prescribed facilities, e.g. special tools 3. Genuine ZF-spare parts meeting the latest state of development Here, all operations are carried out for you with utmost care and reliability. Repairs carried out by ZF-service stations are covered by a respective warranty within the scope of the applicable contractual conditions. Damage caused by improper or unskilled work carried out by others than ZF-staff as well as resulting consequential costs, if any, are excluded from this contractual liability. This also applies, if the use of genuine ZF-spare parts is renounced. ZF Passau GmbH Technology and Axle /1

8 GENERAL The Service Manual covers all works required for the disassembly and the pertaining assembly. When repairing the transmission, ensure utmost cleanliness and that the works are carried out in an expertlike manner. The transmission should only be disassembled for renewing damaged parts. Covers and housing parts installed with seals must be loosened by slight blows with a plastic mallet after screws and nuts have been removed. For removing parts being in tight contact with the shaft such as antifriction bearings, bearing races and similar, use suitable pulling devices. Disassembly and assembly works must be performed at a clean working place. Use the special tools developed for that purpose. Prior to installing again the parts, clean the contact surfaces of housing and covers from old sealing residues. Possibly formed burrs or similar irregularities must be removed with an oil stone. Housing and cover must be cleaned with a suitable detergent, in particular in the corners. Parts which are damaged or heavily worn down must be renewed. Here, an expert must assess, whether parts such as antifriction bearings, stop discs etc., which are subjected to normal wear during operation, can be reused. Parts such as sealing rings, retaining plates, split pins etc. must generally be renewed. Radial sealing rings with worn down or torn sealing lip must also be renewed. Particularly make sure that no chips or other foreign bodies remain in the housing. Lubricating oil bores and grooves must be checked for unhindered passage. Prior to their installation, all bearings must be treated with service oil. REFE- RENCE: For heating up parts such as bearings, housings etc, only a heating furnace or an electric drier is permitted to be used! Parts which are mounted in warm condition must be subsequently driven in after having cooled down to ensure a tight contact. CAUTION When assembling the transmission, absolutely observe the indicated torque limits and adjustment data. Screws and nuts must be tightened according to the enclosed standard table, unless otherwise specified. In view of possible functional failures, for transmissions, the use of liquid sealants as well as of Molykote in the control unit is not permitted. Discs with organic friction linings (e.g. paper discs) must not be washed (affecting the adhesion of the lining). They must be cleaned with a dry method (leather cloth). DANGER When using detergents, observe the instructions given by the manufacturer regarding handling of the respective detergent /2

9 Structure of the Service Manual The structure of this manual follows the sequence of the working steps for the complete disassembly of the unit in dismantled condition. Special tools required for the performance of the respective repair works are listed within the text as well as in chapters "W" (List of special tools) and "WB" (Illustrated tool tables). Important information concerning the work safety Generally, the persons repairing ZF-units are responsible on their own for the industrial safety. The observation of all valid safety regulations and legal impositions is the pre-condition for avoiding damage to persons and to the product during maintenance and repair works. Persons performing repair works must familiarise themselves with these regulations. The proper repair of these ZF-products requires the employment of suitably trained and skilled staff. The persons in charge of the repair are obliged to perform the training. The following safety references are used in the present Workshop Manual: CAUTION You will always find this symbol in the present repair instructions where references regarding special working procedures, methods, information, the use of working aids etc. are given. DANGER This symbol indicates situations where lacking care can entail damage to persons or the product. REFE- RENCE: REFE- RENCE: Prior to starting the checks and repair works, carefully read the present instructions.. Illustrations, drawings and parts do not always represent the original; it is the working procedure which is shown.

The works must be performed according to the description.. REFE- RENCE: After the repair works and the checks, the expert staff members must convince themselves that the product is properly functioning again /3

10 LUBRICATION- AND MAINTENANCE INSTRUCTIONS for the ZF-axle APL-R Oil quality Only oils are permitted to be used which have the qualification according to the ZF-list of lubricants TE-ML 05! The ZF lists of lubricants are updated every two years and can be obtained or studied as follows: - in all ZF works - in all ZF After-Sales Service Centres - Internet -German/English - Information - Techn. Information list of lubricants) In the respective ZF lists of lubricants, you will find information on the following: Oil specification - Manufacturer - Product designation such as Transmission oils without and with Limited-Slip additives etc.... Grease for lubricating points Oil change Drain oil with the axle at operating temperature and the vehicle in a horizontal position. A further condition is the horizontal installation position in either direction of the axle. All draining-, filling- and control screws must be thoroughly cleaned prior to opening. 2.1 Oil drain hole - output To avoid injuries due to a possible pressure build-up in the oil circuit of the planet carrier, bring filling- or control screw (1) into the 'noon' clock position and carefully unscrew it. Then, bring drain bore into the '6 o'clock' position and drain oil Oil filling - output Bring filling bore into position (reference line horizontal to the driving level, see arrow) and fill in oil up to the overflow. Mount new O-ring onto screw plug (1) and mount it. Tightening torque (M24 x 1.5)... M A = 70 Nm 2.3 Oil drain hole axle casing Unfix drain plug (2) and drain oil /4

11 2.4 Oil filling axle casing Provide drain plug (2, with magnetic insert) with new O-ring and mount it. Tightening torque (M36 x 1.5).... M A = 130 Nm Fill in oil up to the overflow at the filling- or control screw (3, position depending on axle version). Provide filling- or control screw with new O-ring and mount it. Tightening torque. (M36 x 1.5)... M A = 130 Nm 2 3 After some minutes, check oil level and refill, if necessary, until the specified level is reached and remains constant! 3. Oil changing interval: 1st oil change after 500 operating hours, every further change after 1000 (i.e. after 1500/2500/ etc.) operating hours, however, at least once per year Reference: Axles with ZF multi-disc self-locking differential When using oils without Limited-Slip additives, minor noise can develop which is not critical. If a strong noise should develop and the wheel roll by jerks, EP transmission oil with Limited-Slip additives must be used. According products are indicated in the ZF-list of lubricants TE-ML Grease lubrication points: Re-lubrication at the forced lubrication nipples - monthly! At the grease lubrication points, a lithium-saponified multi-purpose grease of NLGI-class 2 must be used, which can be mixed with mineral oil (grease designation KP2K-30 as per DIN or ISO-L-XCCHB2 as per ISO/DIS ). 4. Breather: For the axle versions with breather, the latter must be cleaned and subjected to a functional check within the oil changing intervals as well as upon repairs. 5. Oil level check: Oil level check every month, in particular however upon starting up of a vehicle with new or repaired axles or axle parts. 6. Oil for multi-disc brake and hydr. 100% lock of the differential: For the pneumatic-hydraulic actuation or an actuation via accumulator, 1. Engine oil SAE 10 W as per Spec. MIL-L-2104 C, MIL-L-46152, API-CC, CD, SD, SE, SF 2.ATF-oils (Type A Suffix A, Dexron II) are admitted. Attention! Other brake fluids are not permitted to be used!. 7. Oil (brake medium) for hydr.
