Modifications of the 1.0 litre engine compared to the 1.4 litre engine > < Summary of components
1.4 ltr. engine
1.4 ltr. engine
1.0 ltr. engine → Chapter.
   
  Note
t  The design of the 1.0 litre engine is essentially identical to that of the 1.4 ltr. engine. Differences exist only in the version of the crankshaft and its mounting → Chapter.
t  Repairs to the clutch → gearbox; Rep. Gr.30.
t  The engine should be attached to the engine repair stand -MP1-180- or -MP1-202 - on the engine holder -MP9-101- to carry out removal and installation work.
1 - 75 Nm
2 - Crankshaft bearing unit
3 - Thrust washer
q   for middle bearing
q   lubricating grooves point outwards
4 - 8 Nm
q   coat with -AMV 188 520- (Loctite 574) before inserting
5 - Flywheel
q   with sensor rotor for engine speed sender -G28-
q   lock with -MP1-504- for removing and installing.
q   replace ring gear → Chapter
q   installation position to crankshaft:
t  on the 1.0 ltr. engine, the two “missing” teeth of the rotor must face forward when the crankshaft is positioned on TDC for cyl. 1 (marking of belt pulley - crankshaft is opposite marking “0” at timing case)
t  only one installed position is possible for the 1.4 litre engine (since the bore holes are varying distances apart)
6 - 30 Nm + torque a further 90° (1/4 turn)
q   replace
q   before installing, coat with -AMV 200 000- (Loctite 270)
7 - Sealing ring
q   replace
q   remove sealing flange for removing and installing
q   lightly oil sealing lip and outer edge before installing
q   press into the sealing flange
8 - Sealing flange
q   not available as replacement part (only together with cylinder block)
q   coat with -AMV 188 520- (Loctite 574) before inserting
9 - Heat shield
q   for knock sensor -G61-
10 - 5 Nm
11 - 20 Nm
q   The tightening torque influences the knock sensor function
12 - Knock sensor 1 -G61-
13 - Cylinder block
q   Disassemble and assemble piston, conrod and liner → Chapter
14 - 8 Nm
15 - Timing case
16 - Sealing ring
q   replace → Chapter
17 - Belt pulley
q   at the crankshaft
18 - 100 Nm
q   to release and tighten lock flywheel
t  Engine removed: with -MP1-504-
t  Engine installed: with locking screw → Chapter
19 - 7 Nm
q   coat with -AMV 105 500- (Loctite 242) before inserting
20 - Gasket
q   replace
21 - Camshaft sprocket
q   after replacing, inspect synchronous running of chain sprockets → Chapter
q   Camshaft setting → Fig.
22 - Helical gear
q   for oil pump drive
23 - 25 Nm
q   coat with -AMV 154 100- (Loctite 648) before inserting
24 - Timing chain
q   mark running direction (installed position) before removing
q   always replace complete with crankshaft sprocket and camshaft sprocket
25 - Bearing shell
q   for cylinder block with lubricating groove
q   do not mix up used bearing shells (mark)
26 - Crankshaft sprocket
q   after replacing, inspect synchronous running of chain sprockets → Chapter
q   Camshaft setting → Fig.
27 - Woodruff key
q   check tightness
28 - Crankshaft
q   Axial play when new: 0.03 up to 0.13 mm
q   Wear limit: 0.26 mm
29 - Bearing shell
q   for crankshaft bearing unit without lubricating groove
q   do not mix up used bearing shells (mark)
