16 Bias spring 17 Snap ring 18 Reluctor ring 19 Center plate 20 Snap ring 21 Screw (6 off) 22 Spool valve 23 Outer plate Each VCT unit is attached to the camshaft by three bolts. A rotor assembly and a reed plate are installed inside a sprocket housing, which consists of a sprocket, an outer plate and an inner plate held together by six screws.
A reluctor ring, for the CMP (camshaft position) sensor, a center plate and a bias spring are installed at the front of the VCT unit. The ends of the bias spring locate on the center plate assembly and the sprocket housing, to give a turning moment to
the camshaft in the advance direction. A snap ring locates the reluctor ring on to a sleeve installed in the center of the rotor
assembly. The opposite end of the sleeve locates in a bore in the front face of the camshaft, which contains a filter.
A spring and spool valve are installed in the rotor assembly sleeve and retained by a snap ring. The spring keeps the spool
valve in contact with the armature of the related VCT solenoid.
Each VCT unit is supplied with engine oil from an oil gallery in the cylinder head, through the camshaft front bearing cap and a bore in the center of the camshaft.
Variable Camshaft Timing Solenoids
The VCT solenoids control the position of the spool valves in the VCT units.
The VCT solenoids are installed in the front upper timing covers, immediately in front of their related VCT units. Each VCT solenoid is secured with two screws and sealed with an O-ring. A two pin electrical connector provides the interface with the
engine harness.
Each VCT solenoid incorporates a spindle that acts on the spool valve in the related VCT unit to advance and retard the camshaft timing. The VCT solenoids operate independently and are controlled by a PWM signal from the ECM. www.JagDocs.com

The input shaft of the oil pump is driven from the front of the
crankshaft, by the auxiliary chain, at 0.87 engine speed.
The oil pump draws oil from the sump pan through a centrally mounted pick-up pipe. The oil is pressurized and pumped
through an output tube to the cylinder block. After passing through an anti-drain valve and a plate type oil cooler, the oil is
filtered by a replaceable cartridge installed on the front of the RH cylinder head. LUBRICATION SYSTEM
