Tightening torques (Nm)
Note: The tightening torques apply to lightly lubricated, oiled, phosphated or oxidized nuts and bolts. It is allowed to use additional lubricants, such as motor or transmission oils, except those containing graphite. Do not use degreased parts. The tightening torque tolerance is±15%.

Aluminum bolts can be used twice. Therefore, after using the bolts once, 2 notches should be made "X" -arrow-. To avoid damaging the bolts, do not clamp them in a vice. Insert a 14 mm bolt into the head with a 1/2 extension", the other end of which is fixed in a hand vice (as shown in the picture). Bolts marked "X", must not be reused.
Replace bolts that were overtightened. Replace self-locking nuts, lip seals, gaskets and seals. rings. On vehicles with a manual transmission, a needle bearing must be installed in the driven disk. Before installing the disc, make sure the needle bearing is installed. Press the needle bearing into the driven disc. Secure all hose connections with hose clamps of the appropriate series. During installation, all cable ties should be placed in the same places. Before mounting the engine to the gearbox, you must do the following. Insert installation tool -T40169- into the gearbox housing from below and install the dual-mass flywheel as shown in the illustration. The mounting device must fit into the semicircular recess -1- and additionally into the inspection hole -2-. There is only 1 inspection hole, you need to turn the dual mass flywheel accordingly. Insert the bolts of the mounting device into the hole on the gearbox housing.
Insert the transport securing device -T40170- into the gearbox housing from below and secure it to the flange shaft -1-. If necessary, check the possibility of reusing the aluminum engine mounting bolts on the gearbox and mark them.
Vehicles with manual transmission: Make sure that the mounting bushings -A- are present for aligning the engine and gearbox in the cylinder block; if necessary, insert the missing bushings. Place the engine on the gearbox, screw in and tighten bolts -2...6-. The bolt -2- secures the starter to the gearbox and has an additional spacer sleeve -arrow-. The spacer sleeve must be inserted between the starter and the gearbox. Remove the load from the hook -10 - 222 A/10-. Lower the crane and place the engine and gearbox on the engine mounts. Install the engine mount. Remove crane -VAS 6100 and suspension device -2024 A-. Tighten the bolts -1,7,8,9,10- connecting the engine and gearbox. Remove transport securing device -T40170- and mounting device -T40169-.
Vehicles with double clutch gearbox 0B5: Make sure that the mounting bushings -A- are present to align the engine and gearbox in the cylinder block; if necessary, insert the missing bushings. The bolt -2- secures the starter to the gearbox and has an additional spacer sleeve -arrow-. The spacer sleeve must be inserted between the starter and the gearbox. Unload the spindle -10 - 222 A/11-. Lower the crane and place the engine and gearbox on the engine mounts. Install the engine mount. Remove crane -VAS 6100- and suspension device -2024 A-.

The next step is necessary to ensure that the clutch module is evenly adjacent to the driven disc and does not warp. Install wheel arches. Install the front wheels. Engage 4th gear and rotate the front wheels in the direction of travel until the clutch module makes a full rotation. The inspection hole arrow- should again be visible in the recess of the gearbox housing.
Secure the clutch module to the driven disk as follows. Screw in the first bolt -arrow- by hand (2 Nm). Rotate the front wheels in the direction of travel until the clutch module rotates 240°. Tighten the accessible bolt in this position to the specified torque. Rotate the front wheels in the direction of travel until the clutch module rotates 120°and tighten the remaining 2 bolts to the correct torque.
Installation is in reverse order, observing the following. Install the particulate filter. Install reducing agent injector -N474-. Install differential pressure sensor -G505-. Install vibration damper. Install the intermediate roller and tension roller. Install the generator. Install the vane pump. Install ATF lines. Install the compressor. Install the poly V-belt.
Vehicles with front-wheel drive: Install counter support and cross member. Install the lock mounting beam.
