14. Check crimped connection for correct length and distance of strands and insulation, as well as position
and condition of seal.
Correct crimped connection (A):
Insulation and wires are of the correct length in the shackles. Correct distance between the single-strand
insulation and the end of the insulation.
Incorrect crimped connections (B, C):
The single-strand insulation is damaged because the distance between seal and end of insulation is too
small.
Stripped strands are too lon
g, single-strand insulation is therefore not crimped.

1. Wrap fabric tape around repair area as per original condition.
Fabric tape restores the appearan ce of the repair area and provides pr otection from chafing. In parts of
vehicle subject to high levels of st ress (e.g. engine compartment) fabric tape should only be used together
with other (watertight) protective measures.

1. Hypoid gear oils
Hypoid gear oils contain a high level of EP/AW additives (Extreme Pressure/Antiwear) and a highly
viscous base oil to prevent seizure when the hypoid gears mesh (mixed and boundary friction conditions)
and to ensure a high degree of protection against wear. The compatibility with radial shaft seals is
regarded as critical with such high concentrations of additives because the P/S additive systems become
thermally unstable at temperatures from 130°C to 140°C and this may lead to sludging of the hypoid oil.
The resultant deposits on the radial shaft seals then generally lead to thermal overload and this in turn
leads to leakage in this component.
The tooth engagement conditions of the hypoid gears result in a high proportion of sliding and a low
hydrodynamic proportion of tooth engagement between the pinion and ring gear. Due to the high
tribological load compared to adhesive wear (seizure) and pitting, the performance of hypoid gear oils
must be particularly high with respect to these types of wear. The formula of the oils is therefore
determined by a high concentration of EP/AW additives and a highly viscous base oil. Alternative oils,
e.g. engine oils, cannot be used for these drive types. Proof of performance that an oil fulfills the
requirements of DaimlerChrysler AG is provided by internal tests. However, the hypoid gear oils must at
least correspond to the US military specification MIL-L-2105 B/C/D and must be classed GL-5 in the
quality grade according to API (American Institute of Petroleum).
1.7 Viscosity requirements
The cold flow behavior is only specified for SAE, ... oils. Here, the limits apply according to SAE J 306
c, according to which the dynamic viscosity may be max. 150,000 mPas at -40°C for oils and at -12°C for
oils. As a result of the tendency to form deposits in the transmission, the polymer content is limited to
max.
1 percent by weight for pour point reducers. Polymers as VI improvers for thickening low-viscosity base
oils are not permitted. The kinematic viscosity at 100°C must be at least 16.5 mm
2 /s.
2. Transmission oils, sheet 235.1
The additive and viscosity properties of the transmission oils are adjusted so that they meet all the
requirements placed on manual transmissions with steel/molybdenum synchronization, spur gear axles,
MB and ZF transfer cases and reversing gears. Among other things, this results in the fact that the oils
ensure a defined friction coefficient of the synchronizer elements, even after a high number of shift
operations, without crunching noises.
With gear drives and roller bearings, the adhesive wear (seizure) and pitting in particular should be
minimized as far as possible.
2.1 Viscosity requirements
The cold flow behavior is only specified for SAE, 80W, ...oils. Here, the limits according to SAE J 306 c
apply, according to which the dynamic viscosity may be max. 150,000 mPas at -40°C for oils, at -26°C
for oils and at -12°C for oils. Due to the formation of deposits in the transmission, the polymer content is
limited to max. 1 percent b
y weight for pour point reducers. Polymers as VI improvers for thickening

low-viscosity base oils are not permitted. The kinematic viscosity at 100°C 2 must be at least 9.5 mm /s.
In hot zones, gear oils of SAE grade 90 are also permitted.
2.2 Alternative transmission lubricants for commercial vehicle synchromesh transmissions which are
operated with transmission oils as per sheets 235.1, 235.5.
If there are no gear oils according to Sheet 235.1 and 235.5 available, the following engine oils can also
be used as alternatives:
In a moderate climate, engine oils of SAE-grade 30 as per sheet 235.12
In tropical climate, engine oils of SAE-grade 40 as per sheet 235.12
2.3 Fully synthetic transmission oil, sheet 235.4
Completely synthetic gear oils are imperative for the Unimog manual transmission UG 3/40, UG 3/65 and
the PTO transmission -as of the vehicle end No. ...179909 -. Older vehicles can have their oils changed
from gear oils according to Sheet 235.1 to gear oils according to Sheet 235.4 when an oil change is due.
The gear oils correspond to the ZF lubricant specifications TE-ML01 and TE-ML02 and are consequently
alternatives to the gear oils according to Sheet 235.1 in all synchronized ZF manual transmissions
installed in MB vehicles, with and without intarders. Furthermore, the approval extends to the MB
transfer case VG 2400 without oil cooler. Due to the favorable viscosity/temperature characteristics, a
good cold-shifting response and, due to the composition of the transmission oil, a good thermal/oxidative
stability of the oil at high transmission oil temperatures can be expected.
2.4 Transmission oils, sheet 235.5
The gear oils are approved for MB and ZF manual transmissions with steel/molybdenum synchronization,
MB and ZF transfer cases and corner gears.
The transmission oils have a low chlorine content as well as a potential for lower oil temperatures under
certain operating conditions.
2.5 Transmission oils, sheet 235.10
The partly synthetic gear oils are approved for the commercial vehicle manual transmission Model
G16/G28, for the passenger vehicle front-wheel-drive manual transmission SG 150/180 (A class) as well
as for all passenger vehicle in-line transmissions of the model series 717.4 as of transmission serial
number 7 340 241.
Due to the favorable viscosity/temperature characteristics, a very good cold-shifting response and, due to
the composition of the transmission oil, a good thermal/oxidative stability of the oil at high transmission
oil temperatures can be expected.
With regard to the use in passenger vehicle front-wheel drive manual transmissions/in-line transmissions,
which are also installed in cross-countr
y vehicles, the approved gear oil is usually only used in the event
