2.2.1. Regulation of phases of gas distribution by impact on the Z10XEP, Z12XE, Z14XEP camshaft (since the end of 2004 till 2005 release)

In comparison with the end of 2004 of release the way of production of driving gear wheels of the camshaft and a distributive gear wheel of a bent shaft at the above-named engines changed. New driving gear wheels of the camshaft and a new distributive gear wheel of a bent shaft are stamped from a leaf.
Old driving gear wheels of the camshaft and old distributive gear wheel of a bent shaft were produced by an agglomeration method.

Technical features
When replacing a distributive gear wheel of a bent shaft, new, stamped from a leaf, it is necessary to pay attention to that the inscription "FRONT" always showed on a case of the steering mechanism (that is not obligatory for the old, made by agglomeration distributive gear wheel of a bent shaft).

New assembly of a driving gear wheel of the camshaft on a cam-shaft
At the old, made by agglomeration driving gear wheels of the camshaft press the disk is partially fullered with driving gear wheels of the camshaft, see the drawing: comparison of a driving gear wheel of the camshaft.
This technology changed at driving gear wheels of the camshaft, stamped of a leaf.
Press the disk is not fullered now any more, and the bolt of ohms and the old sensor of phases as one detail is established in common with old fixing.
At installation of driving gear wheels of the camshaft, new, stamped from a leaf, it is necessary to pay attention to assembly situation. The surface of a prileganiye of bigger diameter has to be turned to a driving gear wheel of the camshaft.
Follows pay attention that in one engine the driving gear wheels of the camshaft and distributive gear wheels of a bent shaft produced in one method always have to be established.

Driving gear wheels of an old and new sample: I. a new driving gear wheel (the camshaft front view, stamped of a leaf (without press disk)); II. the old driving gear wheel of the camshaft made by agglomeration (with the fullered press disk); 1. front view; 2. press the disk (fullered); 3. rear view; 4. place of centering of the camshaft

Distributive gear wheels of an old and new sample: I. a new distributive gear wheel of a bent shaft, stamped of a leaf; II. the old distributive gear wheel of a bent shaft made by agglomeration

Scheme of a driving gear wheel of the camshaft: 1. press disk of a driving gear wheel of the camshaft; 2. the outer side for a fixing bolt of fastening; 3. inside for a driving gear wheel of the camshaft

Control and adjusting values
* Correction and adjustment is given according to the guide to check by means of TECH2.
** The difference of pressure between separate cylinders should not exceed 100 kPa.
