DESCRIPTION
WRITING COMPRESSION TESTER, made in 2 models, for petrol( ref AC 0100) and Diesel engines, in coming on the market with some important technical advamntages for making easier the work of the mechanic, and consequently it is considered a market leader compared with similar models.
TECHNICAL PROPERTIES
- Card with wide reading scale: scale 8-40, distributed on about 50mm, gives a diagram easy readable and accurate to a precise degree.
- Possibility of recording on the card 8 test (+2 optional ones).
- Newtight quick connection on the false injector for Diesel engines, without use of a spanner.
- Full set of false injectors or false heater plugs for using on any model of Diesel engines (on sale apart ref AC 2024).
UTILISATION
- Warm the engine to its normal operating temperature.
- Stop the engine and put the gear in neutral.
- Remove all the spark-plugs or injectors or heater plugs.
- Close the gas-oil delivery (for Diesel engine only).
- Turn the engine over for a few revolutions to remove loose carbons.
- Put a new card holder and insert it inside the compression tester, as shown in the drawing. In that case, the writing needle in on the inscription “cylinder 1”.
| Important. The wrong position of the bonnet prop could cause the bonnet to
slam shut.

| Be careful to make sure scarves, ties and other items of loose clothing do
not become accidentally trapped in moving parts; this could result in dragging
with serious consequences for the wearer.
| When the engine is hot, proceed carefully inside the engine compartment:
danger of burns.
Remember that when the engine is hot, the electric fan could switch on: injury
hazard.
| Always use personal protective equipment: safety glasses gloves- etc.
DIESEL ENGINES
– Set up the suitable injector-holder or heater-plug instead of the dismounted
ones and connect the tight quick connection from the compression tester to the
false injector or heater plug.
TEST PROCEDURE
Looking through the feed of the needle during the test, it is possible to draw
the following results about the engine conditions:
- Quick-feed of the needle during the first revolutions of the engine and slow-feed until maximum speed during the following revolutions,means piston rings and valve in good conditions.
- Slow-feed of the needle from the first revolutions of the engine, means valve seats probably burnt out.
- Quick-feed during the first revolutions of the engine and following slow-feed: general wear conditions and poor seal of the movers.
TEST RESULTS
At the end of the test, remove the card from the card-holder, and look
carefully at the diagram:
-
The test values accord with the specifications of the engine manufacturer and are equal each other: the tightness of the piston rings and valves is good.
-
The test values are low but equal for all cylinders: general wear of the engine.
-
The test values are very discordant: variable wear in the cylinders with lower value. Lacking wear in some valves.
-
Introducing engine oil through the spark-plug hole or the injector hole, the probable piston ring losses are partly eliminated, therefore, repeating the test, if higher pressure values are reached, this means that the defect is due to the loss of elasticity of bands or cylinder deformity.
If the results are same as before, check the valves. -
If the values are lower in 2 adjacent cylinders: the head gasket relating to these 2 cylinders is probably damaged.
N.B. – Use only writing card on our compression tester 8-40 calibration for Diesel engine models.
ACCESSORIES
- Set of 5 replacement rubbers.
- Set of 48 spare cards 8-40.
- Adapter forM12 spark plug.
