Removal of original parts from the left front side of the engine
1 - retainer; 2 - plug; 3 - bracket; 4 - ignition module
Removing the central injection unit and intake pipe
1 – inlet pipe heater; 2 - inlet pipe; 3 - central injection unit
1. Remove bracket 3 (see fig. Removal of original parts from the left front side of the engine) with ignition module 4, and then plug 2 with gasket and retainer 1 with o-ring.
2. Remove the fuel supply and drain pipes by disconnecting them from the central injection unit and from the bracket on the cylinder head cover.
3. Remove the central injection unit by unscrewing the mounting studs and remove the gasket from the intake pipe surface. Remove intake pipe 2 (see pic. Removing the central injection unit and intake pipe) with heater 1. If necessary, on a workbench, disconnect the heater with gasket and O-ring from the inlet pipe.
4. Remove the crankshaft position sensor mounted on the camshaft cover
5. Further disassembly of the engine is carried out in the usual manner (see subsection 4.3). When removing the connecting rod and piston group, it is not allowed to press out the connecting rod bolts.
Cylinder block
The engine cylinder diameter is as follows:
class A | 82,00 – 82,01 |
class B | 82,01 – 82,02 |
class C | 82,02 – 82,03 |
class D | 82,03 – 82,04 |
class E | 82,04–82,05 |
As with other VAZ engines, cylinder blocks during repairs must be bored and honed for repair pistons (enlarged by 0.4 and 0.8 mm) taking into account the provision of the calculated clearance between the piston and the cylinder 0.025 - 0.045 mm.
When measuring cylinders, caliber 67.8125.9502 is used to set the indicator to zero.
