Alfa Romeo V6 2.5 & 3.0 Quad Cam 24v

Cam block Set

Timing belt replacement on the Alfa Romeo V6 engines is carried out with the crankshaft

at TDC, established by using a TDC position tool to determine the piston position in No.

1 cylinder.

On the Alfa Romeo V6 Quad cam engine the four camshafts are retained in their ‘timed’

positions by this cam block set. These blocks are bolted in position in place of the

designated bearing caps on both inlet and both exhaust camshafts.

Each block is made so that it provides the exact profile and ‘timed’ position of the cam at

the designated bearing location.

IMPORTA"T

Care MUST BE taken when fitting the blocks to ensure –

1. The correct set of plates are being used for the engine.

2. The correct blocks are used on the inlet and exhaust cam shafts – see below

3. Each block is fitted in place of the bearing cap of the designated cylinder only –

again see below

4. Fixing holes in the blocks match the off set bearing cap holes and exactly match

the cam lobe profiles.

Camshaft Cam Block Locations

Left Hand Cylinder Head – Inlet: Bearing Cap No:1 cylinder TA1

Exhaust Bearing Cap No:1 cylinder TA2

Right Hand Cylinder Head – Exhaust Bearing Cap No:4 cylinder TA3

Inlet: Bearing Cap No:6 cylinder TA4

When removing the camshaft bearing caps, clearly mark which is left hand and right

hand, inlet and exhaust and keep clean at all times. When installing the Cam Blocks and

subsequently refitting the bearing caps, always tighten to the specified torque 18-20 Nm.

IMPORTA"T

DO NOT use the cam blocks to hold the camshafts in position whilst releasing or

tightening the sprocket bolts. Cam blocks are for retention of timing position only. Use a

sprocket holding tool to hold the sprockets, taking care not to damage any position

sensors located behind the sprockets.

IMPORTANT: No liability is accepted for incorrect use of this tool
