Beta 1461/C17 Instrucciones página 5

The V W Group 1.2 petrol engine range,
introduced from 2001, can be single camshaft 6
valve engine variants (Codes AWY/BMD) or twin
camshaft 12 valve engines (Codes AZQ/BME).
Chain drive - crankshaft to camshaft(s), they
require use of a Flywheel Locking Pin, common
to all these engines, and a Camshaft Setting
Tool for single overhead camshaft.-AWY/BMD,
and a pair of Camshaft Setting Tools for the
twin camshaft-AZQ/BME engines.
D811 Camshaft Setting Tool - AWY/BMD
Checking valve timing
D811 Camshaft Setting Tool enters through the
top of the engine to locate the 'timing slot' in
the camshaft.
Remove the air cleaner, Hall sender unit and
engine speed sensor.
Turn the crankshaft, in the normal direction of
engine rotation, so that the 'timing slot' in the
camshaft is visible in the hole used for the Hall
sender unit.
Insert D811 Camshaft Setting Tool. It should
locate into the camshaft 'timing slot' with ease.
Secure the tool in place with a M6 bolt.
D813 Flywheel/Crankshaft Locking Pin
(D813 is used for both twin camshaft and single
camshaft engines (Codes AWY/BMD/AZQ/BME)
The crankshaft is locked in timed position by
inserting D813 Pin through the engine housing
and into the flywheel. If, with D811 Camshaft
Tool in position, it is not possible to insert the
D813 Pin, remove D811 Camshaft Tool, turn
the engine 360°, and then insert Camshaft Tool
and Flywheel Pin.
Valve Timing Adjustment
If it is not be possible to insert both the
Camshaft Tool and Flywheel Pin with ease, the
engine timing can be adjusted. First, positioning
the 'timing slot' in the camshaft so it is visible in
the hole used for the Hall sender unit and
insert D811 Tool.
Next, using a suitable sprocket counter-holding
tool, counter-hold the camshaft sprocket and
slacken its bolt. Then, turn the crankshaft until
D813 Pin can be inserted correctly into the
flywheel.
Finally, counter-hold the camshaft sprocket and
tighten the sprocket bolt.
Remove both tools, rotate the crankshaft 2 times,
and recheck valve timing by ensuring D811 and
D813 can be fitted correctly and with ease.
D812 Camshaft Setting Tools (Pair) - AZQ/BME
Engine setting and locking on the twin
camshaft engines is a similar procedure to that
used on the single camshaft engines, except
the pair of Camshaft Setting Tools - D812,
enter 'timing slots' in the rear of the camshafts.
Remove the air cleaner and both camshaft end
covers located at the rear of the camshafts.
Remove the engine speed sensor and rotate
the crankshaft so that the 'timing slots' in the
rear of camshafts are horizontal.
D812 Camshaft Setting Tools can now be
inserted into the 'timing slots' and secured in
place with M6 bolts, hand tight only.
The crankshaft is locked in timed position by
inserting D813 Pin through the engine housing
and into the flywheel, the same position as
used for single camshaft engines.
For valve timing adjustment on twin camshaft
engines, fit both of the D812 Camshaft Setting
Tools and slacken both camshaft sprocket bolts.
Insert D813 Flywheel Locking Pin and counter-
hold camshaft sprockets whilst tightening the
sprocket bolts. Follow the same procedure as
detailed in "Valve Timing Adjustment" section
above.
