INTRODUCTION
The efficiency and continued operation of mechanical units depend on constant, correct maintenance and also on efficient re-
pair work, should there be a break-down or malfunction. The instructions contained in this manual have been based on a com-
plete overhaul of the unit. However, it is up to the mechanic to decide whether or not it is necessary to assemble only individual
components, when partial repair work is needed. The manual provides a quick and sure guide which, with the use of photogra-
phs and diagrams illustrating the various phases of the operations, allows accurate work to be performed.All the information
needed for correct disassembly, checks and assembly of each individual component is set out below. In order to remove the
differential unit from the vehicle, the manuals provided by the vehicle manufacturer should be consulted. In describing the fol-
lowing operations it is presumed that the unit has already been removed from the vehicle.
IMPORTANT: In order to facilitate work and protect both working surfaces and operators, it is advisable to use proper equip-
ment such as: trestles or supporting benches, plastic or copper hammers, appropriate levers, pullers and specific spanners or
wrenches. Before going on to disassemble the parts and drain the oil, it is best to thoroughly clean the unit, removing any en-
crusted or accumulated grease.
INTRODUCTORY REMARKS: All the disassembled mechanical units should be thoroughly cleaned with appropriate products
and restored or replaced if damage, wear, cracking or seizing have occurred. In particular, thoroughly check the condition of
all moving parts (bearings, gears, ring gear and pinion, shafts) and sealing parts (o-rings, oil shields) which are subject to major
stress and wear. In any case, it is advisable to replace the seals every time a component is overhauled or repaired. During as-
sembly, the sealing rings must be lubricated on the sealing edge. In the case of the ring gear and pinion, replacement of one
component requires the replacement of the other one. During assembly, the prescribed pre-loading, backlash and torque of
parts must be maintained.
CLASSIFICATION: This manual classifies units according to part numbers. For a correct interpretation, classification is indica-
ted as follows:
XX= up to the part number
XX= from the part number on
When no classification is given, disassembly and assembly operations are the same for all versions.
SPECIFIC EQUIPMENT AND SPARE PARTS: The drawings of all specific tools required for maintenance and repair work can
be found at the end of this manual ; spare parts may be ordered either from the vehicle manufacturer or directly from the Service
Centers or Authorized Distributors of SPICER.

LUBRICANT & SEALANT SPECIFICATIONS
1 - Locking, sealing and lubricating materials referred to in this manual are the same used in the shop-floor.
2 - The table below gives an account of the typical applications of each single material, in order to facilitate replacement with
similar products marketed by different brand names with different trade marks.
LOCTITE 242
Anaerobic product apt to prevent the loosening of screws, nuts and plugs. Used for medium-strength locking. Before using it,
completely remove any lubricant by using the specific activator.
LOCTITE 243
The oleocompatible alternative to 242. Does not require the activation of lubricated surfaces.
LOCTITE 270
Anaerobic product for very-high strength locking of screws and nuts. Before using it, completely remove any lubricant by using
the specific activator.
To remove parts, it may be necessary to heat them at 80° C approximately
LOCTITE 275
Anaerobic product suitable for high-strength locking and sealing of large threaded parts, bolts and stud bolts, for pipe sealing
and for protecting parts against tampering; suitable for sealing coupling surfaces with a maximum diametrical clearance of 0.25
mm.
LOCTITE 510
Anaerobic product for the hermetic sealing of flanged units and screw holes communicating with fluids. Can seal clearances
between flanges up to 0.2 mm.
LOCTITE 577
Quick anaerobic sealant for sealing threaded portions of conical or cylindrical unions up to M80. Before using it, remove any
lubricant with the specific activator. After polymerisation, disassembly may result rather difficult, so heating may be necessary
for larger diameters.
LOCTITE 638
Anaerobic adhesive for fast and high-strength gluing of cylindrical metal joints (hub on shaft). Can glue together parts with cle-
arance ranging between 0.1 and 0.25 mm.
LOCTITE 648
Anaerobic adhesive for fast and medium-strength gluing of cylindrical metal joints (hub on shaft). Can glue together parts with
radial clearance below 0.1 mm.
AREXONS (REPOSITIONABLE JOINTING COMPOUND FOR SEALS)
Solvent-based sealing compound for elastic seals, drying through evaporation. Used for sealing the outer diameter of sealing
rings for rotating shafts with outer metal reinforcement.
SILICONE
Semi-fluid adhesive material used for sealing and filling and to protect components from environmental and physical elements.
Polymerises with non-corrosive dampness.
TECNO LUBE/101 (SILICONE-BASED GREASE)
Highly adhesive synthetic grease, with silicone compounds added.
Applied to adjustment screws with hole communicating with oil-type fluids.
Used when frequent adjusting is required.
