Gazelle until 2009. Disassembly and assembly of the UMZ-4216 engine - part 1

We disassemble the engine to assess the technical condition and replace the failed parts of the crank mechanism. Remove the engine from the car (see "Removing and installing the engine", p. 67). To securely fix the engine, we put wooden blocks of suitable dimensions under the brackets of the power unit supports, the oil pan, the clutch housing and disconnect the lifting chain from the eyebrows. Remove the cylinder head assembly with the receiver, intake pipe and exhaust manifold (see "Removing the cylinder head", p. 56).

Remove the generator and its lower mounting bracket (see "Removing the 3282M.3771 generator", p. 267). Remove the starter (see "Removing and checking the starter", p. 272).

Using the "24" wrench, unscrew the adapter assembly with a tap from the hole in the cylinder block.

Remove the crankshaft position sensor (see "Removing the crankshaft position sensor", p. 83) and the phase sensor (see "Removing the phase sensor", page 83).

Remove the crankshaft pulley (see "Replacing the front crankshaft oil seal", p. 59). We unscrew the oil filter (see "Changing the oil and oil filter", p. 44). Remove the coolant pump (see "Removing the coolant pump", page 112). Remove the fan drive belt tensioner (see "Removing the fan drive belt tensioner", p. 64). Remove the electromagnetic clutch for switching on the fan (see "Removing the electromagnetic clutch for switching on the fan", p. 110).

Further disassembly of the engine can be performed on a universal disassembly and assembly stand. To do this, it is necessary to remove the bracket of one of the power unit supports and attach the stand plate with bolts screwed into the threaded holes of the cylinder block, which are designed to fasten the power unit support bracket. If there is no stand, unscrew the cylinder head mounting studs from the cylinder block and install the block with the flat side on the workbench. Remove the brackets for the power unit supports (see "Replacing the power unit supports", p. 65). Using the “36” head, we unscrew the bolt securing the crankshaft pulley hub (we hold the shaft from turning with a mounting blade inserted between the teeth of the flywheel crown and the clutch housing).

Press the pulley hub off the toe of the crankshaft (see "Replacing the front crankshaft oil seal", p. 59).
