Clutch
Depending on your engine, the clutch will usually be the standard part. It may be you have a balanced clutch system if the engine has been dynamically balanced.
Ford V6 Essex 3.0 Clutch
This is a general reference section for the Ford Essex 3 Litre Clutch assembly, allowing you to correctly identify a new kit without removing the old one, and also to check for wear. This is based on my findings when changing clutches on these models.
Friction Plate
Friction Plate Diameter = 240mm
Marking on gearbox side of plate = 52509
Marking on flywheel side of plate = 50052
Depth of friction plate to rivet heads = 2.1mm on a new friction plate
Depth of friction material (only) on one side = 4.3mm on new friction plate
Thickness of friction material (total from face to face) = 9.5mm on a new friction plate
Splines = 23
Number of springs in friction plate = 6 - should be tight. Any rattle means starting to wear and will be noisy
Friction plate hub depth = 33mm
Pressure Plate
Borg & Beck Marking Type 9/9½ D.S.
C28H marking found on one spring spoke
18 Spring Spokes in total
Outside diameter of clutch contact surface = 244mm
Inside diameter of clutch contact surface = 152.2mm (6" exactly)
Maximum diameter of outer housing = 287.5mm (11 5/16")
P.C.D. of fixing bolt holes = 273.5mm (10 6/8")
New pressure plate height (measured when laying flat on a flat surface to the top of the spring spokes) = 59.4mm. If the springs are uneven where they contact the release bearing then this will mean wear is evident. Replace if in doubt, and certainly if any springs are broken.
Thrust (Release) Bearing
Marking = >PA66 GF35<
INA (8 or 9)02993
00 94
Worn out pressure plate - the release bearing won't sit flat on all the spring spokes
