Aluminum bolts -2...10- may not be used more than 2 times. Therefore, after the first use, mark such bolts with two notches using a cutter "X" -arrow-. To avoid damaging the bolts when notching, do not secure 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). Tagged "X" Do not reuse bolts.
Bolts that are tightened at a tightening angle should be replaced. Replace self-locking nuts and bolts, 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 that the needle bearing is already installed. Press the needle bearing into the driven disc. Hose fittings, air pipes and hoses must be cleaned of oil and grease before installation. To ensure reliable fastening of the air hoses to the fittings, the threaded connections of already used clamps should be treated with a rust remover. During installation, all cable ties should be placed in the same places. Be sure to clean the threaded holes for fixing the power unit in the cylinder block before assembling the gearbox with a tap. Before connecting the engine and gearbox, carry out the following preparatory steps: Install the mounting tool -T40169- from below under the gearbox housing and the dual-mass flywheel, as shown in the figure. The mounting device must fit into the semicircular groove -1 - and additionally into the control 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. Install the transport protection-T40170-from below under the gearbox housing and attach it to the flange shaft -1-. Check the aluminum bolts connecting the engine to the gearbox for reuse and mark if necessary.
Check the presence of centering sleeves -A- for the engine and gearbox in the cylinder block, insert the sleeves if necessary. Place the engine on the gearbox, screw in and tighten bolts -2...6-. Bolt -2- secures the starter to the gearbox and has an additional spacer sleeve -arrow-. The spacer sleeve must be located between the starter and gearbox. Relieve spindle -10-222 A/11-. Lower the crane and place the engine and gearbox on the engine mounts. Install the engine mount. Remove service tap -VAS 6100- and hanging device -2024 A-. Tighten bolts -1, 7, 8, 9, 10- connecting the engine and gearbox. Remove transport securing device -T40170- and mounting device -T40169-. The next step is necessary to ensure that the clutch module evenly adheres to the driven disk and does not warp. Install the front wheels. 4. Engage the gear and rotate the front wheels in the direction of travel until the clutch module makes a full revolution. The inspection hole -arrow- should again be visible in the recess of the gearbox housing.
Tighten the clutch module bolts on the driven plate 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 so that the clutch module rotates 120°accordingly, and tighten the remaining 2 bolts to the tightening torque. Install in reverse order, observing the following: Install the particulate filter. Install the exhaust pipe.
Align the exhaust system without mechanical stress. Install the torsional vibration damper. Install the intermediate roller and tension roller. Install the generator. Install the vane pump. Install the compressor. Electrical connectors and wiring. Install the engine control unit. Install wires, splitter 2 cells. 30 -TV22- and the engine switch box cover. compartment Install a stretcher. Install the windshield washer reservoir filler pipe. Pay attention to the battery installation work. Do not use the charger to start the engine. Install the air housing. filter. Check oil level. Fill with coolant. Do not use drained coolant in the following cases: When replacing the cylinder head or cylinder block. When the coolant is contaminated. Install wheel arch liners and sound insulation.
