1997 MERCEDES-BENZ ML500 wheel bolt torque

Basically automatic transmission 722.6 with electronic control offers the following advantages:
Reduced Fuel Consumption
Improved Shift Comfort
More Favorable Gear Steps As A Result Of 5 Gears
Enhanced Life And Reliability
Reduced Servicing Costs
The electrohydraulic control unit is bolted onto the bottom of the transmission housing. The end of the
transmission is formed by an oil pan made of sheet steel.
The oil pressure for the converter lockup clutch and center multiple-disc clutch is supplied via holes in the input
shaft. The oil pressure to the rear multiple-disc clutch is routed through the output shaft. The lubricating oil is
supplied and distributed by additional bore holes in both shafts. All bearing points of the gear sets as well as
freewheels and shift elements are supplied with lubricating oil.
The parking lock gear and drive flange are connected to the output shaft by gearing.
Freewheels F1 and F2 optimize shifting. The front freewheel (F1) rests against the stator shaft extension on the
transmission side and connects the sun gear of the front planetary gear set to the transmission housing in the
locking direction.
The torque converter housing and transmission housing are made of a metal alloy. They are bolted together and
centered via the outer multiple-disc carrier of the multiple-disc brake B1. A coated intermediate panel seals the
two components.
The oil pump and outer multiple-disc carrier of the front multiple-disc brake are bolted to the converter housing.
The mechanical part consists of the propeller shaft, output shaft, a sun gear shaft and three planetary gearsets
which are coupled together.
In transmissions for powerful engines, the planetary gearsets have 4 planetary gears, while for less powerful
engines the front and rear planetary gear system has three planetary gear wheels. The stator shaft is pressed into
this and is secured against turning by a spline.
The rear freewheel F2 connects the sun gear of the center planetary gear set to the sun gear of the rear planetary
gearset in the locking direction.
The electrohydraulic control unit consists of the shift plate made of light alloy for hydraulic control and an
electronic control unit.
The electrical control unit consists of a supporting body made of plastic in which the electrical components are
combined. The shell is screwed to the shift plate. Conductor tracks which are integrated into the shell, connect
the electric components to a plug connector. This 13-pin plug connector forms the connection with the vehicle-
side wiring harness and with the ETC 5 (electronic transmission control) control module (N15/5) via a bayonet
lock.

Rims
D
When changing wheels, for instance, when replacing steel

wheels with light-alloy rims, ensure that the wheel bolts

required for the spare wheel are stored in a clearly visible

location.

D
Since December 1994 models 202 and 124 with special

equipment light alloy disk wheels, are supplied with a sheet

steel spare wheel instead of a light alloy spare wheel. The

necessary wheel bolts are included with the steel spare wheel.

D
Only use approved Mercedes-Benz rims of the same version.

D
Reinforced steel rims are identified by a sticker on the wheel

disc.

D
The wheel bolts on steel and light-alloy rims should always be

tightened to the specified tightening torque using a torque
wrench.

It is not necessary to retorque the lug bolts after approximately

100 to 500 km.
D

The seat for the tire bead must display no corrosion marks.

D
Before inserting a new rubber valve, clean the contact surfaces

on the disk wheel.

On sheet steel-disk wheel wheel trims must be fitted to support

the rubber valve.


Damaged or deformed rims must not be repaired.

Tire pressure monitor
D
Before replacing a tire, check the date of manufacturer of the

wheel sensor: wheel sensors which are more than 5 years old

must be replaced.

D
Use STAR DIAGNOSIS to read out the actual values of the tire

pressure monitor. Check the remaining life of the wheel sensor

battery, replace the wheel sensor if necessary.

TESTING
Starter malfunctions may cause a Di agnostic Trouble Codes (DTCs) to be stored in Motor Electronics
Sequential Fuel Injection (ME-SFI) sy stem. After repairs are completed check for and erase any DTCs stored in
(ME-SFI) system. See appropriate SE LF-DIAGNOSTICS article in ENGINE PERFORMANCE. If cause of
starter malfunction is not engine pe rformance related, replace starter.
REMOVAL & INSTALLATION
STARTER
Removal & Installation
1. Disconnect and shield negative battery cable. See BATTERY DISCONNECT/CONNECT under
SERVICE PRECAUTIONS.
2. Remove nut (2) for inner fender. See Fig. 5
. Pull front and rear section of inner fender (1) downward.
Move inner fender away inward and downward. Pull toward outside over wheel. DO NOT damage fender
cutout or paint.
3. On vehicles with 112 engine, remove nut (6) at shield (5) of left engine mount and take out shield. See
Fig. 6
.
4. On all vehicles, disconnect circuit 30 (1) and circuit 50 (2) cables from starter. See Fig. 6
. Remove bolts
(3) for starter-to-crankcase. Take starter (M1) out to the side.
5. If replacing starter on vehicles with manual transmission, check ring gear at flywheel for wear and
damage. If replacing starter on vehicles with auto matic transmission, check ring gear on drive plate for
wear and damage. Repair or repl ace damaged parts as necessary.
6. To install, reverse removal proce dure. Replace bolts with locking splines, micro-encapsulated bolts and
self-locking nuts. Mating thread of mi cro-encapsulated bolts must be cleaned to remove all residue of old
bolt locking compound. Tighten fasteners to specification. See TORQUE SPECIFICATIONS
. Connect
battery. See BATTERY DISCONNECT/CONNECTunder SERVICE PRECAUTIONS.
