Tightening torques

Note. Tightening torques apply to lightly lubricated, oiled, phosphated or oxidized nuts and bolts. The use of additional lubricants, such as motor or transmission oils, is permitted, except for graphite-containing ones. Do not use degreased parts. The tolerance of tightening torques is ±15%.

Bolts and nuts

M6: 9 Nm, M7: 15 Nm, M8: 20 Nm, M10: 40 Nm, M12: 65 Nm.

Bolt of mass to the body near the cup of the shock absorber strut. Tightening torque

Tighten the ground bolt "1" to 9 Nm.

Ground wires to side members. Tightening torque

Tighten the arrow nut to 9 Nm.

1) Bolt strength class 10.9, steel bolt can be used repeatedly
2) Aluminum bolts can be used twice

Aluminum bolts "2...11" are allowed to be used no more than 2 times. Therefore, after a single use of the bolts, 2 notches "X" "arrow" should be made.

To avoid damaging the bolts, do not clamp them in a vice. Insert the bolt into the head by 14 mm with an extension 112, the other end of which is fixed in a hand vice (as shown in the picture). Bolts marked with "X" must not be reused.

Note. Replace bolts that were tightened with additional turning. Replace self-locking nuts, lip seals, gaskets and sealing rings. On vehicles with 0B6 automatic transmission, the driven disk may not have a needle bearing. Before installing the disk, make sure that the needle bearing is installed. Press out the needle bearing from the driven disk. Secure all hose connections with hose clamps of the appropriate series. To ensure reliable fastening of the air duct hoses to the fittings, treat the threaded connections of the already used clamps with a rust remover. During installation, all cable ties should be placed in their original places.

When installing the engine on the subframe, hold the ATF lines in the installation position. Be sure to clean the threaded holes for fixing the power unit in the cylinder block with a tap before assembling the gearbox. Before fixing the engine to the gearbox, do the following: rotate the torque converter so that the hole next to the notch "arrow" is visible in the opening under the gearbox housing, as shown in the figure.

In order to find the notch, it is necessary to rotate the torque converter. Insert the transport fastener

"T40170" from below into the gearbox housing and secure on the shaft with flange "1".

If necessary, check the possibility of reusing the aluminum engine mounting bolts on the gearbox and mark them.

Make sure that the installation bushings "A" for aligning the engine and gearbox in the cylinder block are present; if necessary, insert the missing bushings. Install the gearbox on the engine and tighten the bolts "1...11". Remove the transport protection "T40170". Install the engine mounts and engine mount. The next step is necessary so that the torque converter fits evenly to the driven disk and does not warp. Lightly press the torque converter "2" with the crowbar "1" to the driven disk "3", see "arrow direction".

Secure the torque converter to the driven disk as follows: Use a 16 mm ring spanner to tighten the bolts "V.A.G 1332/14". Screw in the first bolt "arrow" manually (2 Nm).

Insert the guide pins of the adapter "T40058" as shown below: Large diameter "arrow 1" faces the engine. Small diameter "arrow 2" faces the adapter. Turn the crankshaft using the adapter "T40058" by 180° in the direction of engine rotation "arrow".

In this position of the crankshaft, tighten the accessible bolt "arrow" to the specified tightening torque.

Turn the crankshaft 60° and tighten the remaining 5 bolts to the specified tightening torque. Install the hydraulic lines of the power steering. Bolt the left and right drive shafts to the axle shafts with the gearbox flanges. Install the drive shaft heat shield. Install the exhaust manifold: left, right. Raise the power unit with the lifting table "VAS 6131 A". Position the subframe and gearbox bracket according to the markings made on the side members during dismantling. Tighten the subframe bolts to the prescribed tightening torque, but do not tighten them at an angle (tightening only after measuring the wheel alignment angles). If the subframe bolts are not fully tightened, the car cannot be moved. Tighten the tunnel crossmember "arrow" bolts.

Installation in reverse order: Install the ATF lines. Tighten the universal joint mounting bolts with the crosspiece on the steering gear. Install the propeller shaft. Install the selector cable. Install the additional muffler. Install the subframe brace, upper suspension arm, stabilizer, tighten the shock absorber strut mounting bolts on the support arm. Install the brake caliper. Install the engine control unit. Electrical connectors and wiring. Install the wires, 2-valve splitter 30 "TV22" and the cover of the engine compartment switching unit. Install the brace. Install the washer fluid reservoir filler neck. Install the refrigerant lines. Follow the instructions after connecting the battery terminals. Risk of damage to the control units due to overvoltage. Do not use a charger to start the engine! Install the fuel injection hose and air filter housing. Install the cross members of the lock mounting beam. Fill in oil and check its level. Before starting the engine for the first time, pour hydraulic oil into the expansion tank of the power steering. The vane pump of the power steering should not run "dry". Connect the coolant hose using a coupling. Fill with coolant.

Fill the air conditioning system circuit. Install the front wheels and adjust the wheel alignment angles. Tighten the subframe bolts after checking the wheel alignment angles. Check the ATF level. Install noise insulation screens and mudguards.
