Instructions for use – Always refer to the vehicle manufacturer's service manual or a suitable proprietary instruction book.
Warning – Incorrect or out of phase engine timing can result in damage to the valves. It is always recommended to turn the engine slowly, by hand, and to re-check
the camshaft and crankshaft timing positions.

Camshaft Setting Tool:-
NOTE FT 23064 Camshaft Setting Tool is used with associated FT 23163 Camshaft Locking Tool.
FT 23064-06 is used with the Dial Test Indicator using the Adapter Assembly FT 23064-01 and replacing the
Standard Tip on the Dial Test Indicator with Special Tip FT 23064-05 See Fig. 1
Ensure all timing marks align at crankshaft by using (FT 23164-01 or FT 23164-02), and at the injection pump.
Carry out the timing belt tensioning procedure as per the manufacturers instructions. The Belt tension must be
correct.
Turn crankshaft in the normal engine direction of rotation to 90 degrees before TDC (1
Dial Test Indicator into Setting Plate. The DTI shaft must be held securely in the Adapter.
Initially retain the DTI shaft by lightly pinching with the Nut.

nd
2/. Push Plate to the right to rest against the right stop position. The DTI foot should rest on the base circle of the
cam.
3/. Release the Nut and pre-load the indicator to not more than 0.50 mm. and secure the (DTI) firmly in the
Adaptor.
4/. Zero the DTI bezel (datum point)
5/. Push the Block to the left to rest against the left stop position so that the indicator rests over the cam lobe.
NOTE: The dial test indicator will now read below the datum point.
6/. Turn crankshaft in the normal engine direction to TDC ensuring all timing marks align. The cam lobe will rise
and the DTI will return to the zero datum point and continue to the correct nominal value 0.55 +/- 0.03mm. If
the nominal value is not obtained, the cam timing must be adjusted.
Adjusting Timing:
Ensure that the timing belt tension is correct. All timing marks must be aligned and the engine at TDC.
Using a 22 mm. open-ended spanner on the camshaft hexagon to stop it from turning, loosen the fastening bolt
of the camshaft sprocket. It is important that the position of the crankshaft and camshaft remain unchanged.
The Camshaft should now be turned using the spanner in the normal direction of rotation until the dial test indica-
tor reads approximately 0,80mm. Then using the spanner, turn the camshaft back in the opposite direction of
normal rotation until the Dial Test Indicator reads 0,60-0,64mm. It is important that the camshaft does not move
from this position. Fit the Camshaft Locking Tool FT 23163 to any of the remaining three cylinder positions, and
adjust the thumbscrews down until they make contact with the cam lobes. See Fig.2. Fit a new bolt to retain the
camshaft sprocket and tighten to the specified torque. Remove both timing tools, but do not change the Dial Test
Indicator setting.
Rotate the crankshaft two full revolutions to the correct timing marks. Re-install the camshaft measuring tool, en-
suring that the Dial Test Indicator is in the left stop position, with the (DTI) resting on the cam lobe. Check that the
correct nominal measurement reading is shown as 0,55 +/- 0,03mm.
Flywheel TDC Setting Tool - Vauxhall/Opel, 17DTL engine (-97)
When removing/installing timing belt and establishing or checking correct timing position, the Flywheel Setting
Tool is used to determine the flywheel/crankshaft TDC position. It is attached to the flywheel housing and provides
the 'pointer' position on which to align the TDC mark.
Flywheel / Crankshaft Locking Tools.
These are designed to pin-point and lock the engine at Top Dead Centre (TDC) by alignment of a datum hole in
the flywheel / engine casing and the flywheel. Place the correct Pin in the access hole and rotate the engine by
hand until the locking pin engages with the flywheel timing hole, the engine is now locked in the correct timing
position.
