Attention! There is very little room to work on the removal of the engine oil pan, so it is necessary to lower the front axle beam. Measurement of the angles of the front wheels at the end of the work can be omitted.
Removing the pallet (29, see fig. 3.14) oil sump and replacement of its seal (37) must be carried out with an assistant in the following order.
oil sump

Prepare fixtures «00.0.200», «00.0.201». «00.0.202», «00.0.204», «00.0.208», «00.2.030», «11.0.020», «31.2.220» And «51.2.170».
Remove the bulkhead of the engine compartment heater. Fix the hood in the installation position using the tool «51.2.170».
fixture «51.2.170»
Remove nozzle cover (see fig.3.32) and the upper part of the air filter housing together with the air flow meter (IRS).
Fix the engine with the tool assembly (pic. 3.74). Fixture supports «00.0.208» must rest on bolts in both wings of the body.
Remove the alternator drive belt from the power steering pump pulley. Remove the pump and fix it to the body with a wire clamp, do not disconnect the hoses.
Unscrew the oil drain plug, drain the engine oil and send it for disposal. Disconnect the return hose from the crankcase breather oil separator. Remove the oil dipstick guide tube.
Disconnect the oil lines from the automatic transmission and the oil pan. Remove the air filter housing, front engine accessory protection panel and stiffening plate.
Loosen the top nuts on the left and right engine mounts (arrow, fig. 3.75) and lift it up with a tool «00.0.200» about 5 mm.
Support the front axle beam with tools «00.2.030» And «31.2.220», using a wooden beam.
Attachment 00.2.030
Device 31.2.220
Detach the control arm brackets from the left and right side members.
Disconnect the left and right stabilizer retaining brackets.
Note. The steering gear remains attached to the front axle beam. When lowering the front axle beam, make sure that the steering gear hoses are not stretched.
Unscrew the bolts of the front axle beam, disconnect it from the front side member and carefully lower it by 90-100 mm. Remove the front axle gearbox.
Mark bolts (M6) (pic. 3.75a) fixing the oil pan, because they have different lengths on the timing and gearbox sides.
Loosen the oil pan mounting bolts. Remove the oil sump, downwards and backwards.
Installation of the oil pan should be carried out in the reverse order, if necessary. Using a hardwood scraper, clean the sealing surfaces of any old gasket residue. In the area of \u200b\u200bthe joints of the rear crankshaft oil seal and the timing cover, apply a layer of sealant such as «Drei Bond 1209» about 3 mm wide and 2 mm high (pic. 3.76).
Attach the new gasket to the sump with a small amount of grease. Check the correct position of the gasket. Insert all oil pan bolts and screw them in by hand without tightening. Screw in the bolts on the transmission side but do not tighten them.
Tighten bolts on timing and engine block side. Tighten bolts on gearbox side. Tighten the fastening bolts to a torque of 10-12 Nm (1.0—1.2 kgf·m), but do not overtighten, otherwise the tightness of the gasket is lost.
Install the stiffening plate by tightening the mounting bolts to a torque of 56 Nm (5.6 kgf·m) and subsequent turning through an angle of 90°Tighten the nuts of the engine mounts to a torque of 45 Nm (4.5 kgf·m).
Replace oil drain plug seal and tighten to 25 Nm (2.5 kgf·m). Pour oil into the engine, replace the ring (26, see fig. 3.14) steep section on guide tube (24) and check the oil level in the engine and power steering reservoir (see section «Maintenance»).
Carry out a test drive and check the tightness of the oil pan. If necessary, slightly tighten the crankcase mounting bolts.
