Checking the Valve Timing

WARNING: This page is about a different car, the 2015 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: There is a risk of damaging the engine by the toothed belt jumping off.

Only rotate the crankshaft in the direction of engine rotation.

-- Turn the crankshaft by the toothed belt pulley bolt two turns in the direction of engine rotation until the crankshaft is once again just before "TDC".

-- Mount the Crankshaft Lock T10490 on the crankshaft toothed belt gear.

-- Turn the crankshaft in direction of engine rotation, until the tip -arrow- on the crankshaft stop fits into the sealing flange.

CAUTION: An inaccurate "TDC" setting will cause an inaccurate setting.

If the crankshaft was turned past "TDC" : Turn the crankshaft again two turns until it is just in front of "TDC." Then secure the crankshaft from moving using the Crankshaft Lock T10490.

It must be possible to secure the camshaft hub with the Diesel Injection Pump Locking Pin 3359.

It is very difficult to find the locking point on the high pressure pump hub. A small deviation -arrow- does not affect engine operation.

The pointer on the tensioning roller -2- must be in the middle between the tabs -1- and -3- on the plate.
