B1EE08K1 - 206 DW10TD ENGINE

CHECK END OF COMPRESSION PRESSURES

1 - SPECIAL TOOLS

DW10TD ENGINE

[1] Dummy plug + compression meter adapter (-).0188-U .

[2] Flywheel setting rod (-).0188-Y .

[3] flywheel stop (-).0188-F .

DW10TD ENGINE

DW10TD ENGINE

[4] FACOM 910A type sealing checker .

[5] Diesel engine adapter, FACOM 910.A6 type .

2 - CHECK

Ensure that the speed of engine rotation, driven by the starter, is correct (Minimum value : 250 rpm) .

Check to be made : Engine cold .

Disconnect :

- the battery
- the engine control ECU
- supply to the glow plugs

Insulate the glow plugs supply lead .

DW10TD ENGINE

Remove :

- the right-hand bracket of the styling cover
- the glow plugs supply rail
- the glow plugs

Position :

- tool [1] and its adapter (depending on the type of compression tester) on cylinder no. 1; tightening torque 1 da.Nm
- compression tester

Connect the battery .

Measure the end of compression pressure on the cylinders 1, 2, 3, 4 in order :

- minimum value : 25 to 30 bar(s)
- the maximum permissible difference between cylinders is 5 bars

If the values are low, before considering an engine overhaul, check the condition of the air filter and cylinder head gasket .

3 - COMPRESSION LOSS MEASUREMENT

Check to be made : Engine cold .

DW10TD ENGINE

DW10TD ENGINE

Peg the flywheel using the rod [2] .

DW10TD ENGINE

Make a mark (A) on the casing and the pulley, to indicate the Top Dead Centre (TDC) of cylinder 2 and 3 .

DW10TD ENGINE

Insert the flywheel stop [3] .

Remove the rod [2] .

Determine which cylinder is at the end of compression phase (1 or 4), using tools [1], [4] and [5]; Tighten tool [1] to 1 daN.m .

Connect the measuring equipment using the modified end piece (see equipment instructions) .

Read the loss of compression (Correct value : Approximately 20 %) .

If the value is incorrect, faulty parts can be located by locating the noise made by the passage of air .
