I've seen a number of 03 Pros for sale that state 04 Clutch mod fitted. Having studied the two parts manuals I can only see that the plates (steel and friction ) are a different part number and there's a pair of roller bearings used instead of a bush in the centre of the basket onto the gearbox shaft. Is this the mod ?

As I was planning to get the cover off to check the measurements of the clutch pack, is it worth looking at the bearing replacement and plates while I'm at it. My clutch is heavy and seems to drag a bit. (probably due to the oil not being replaced for some time - the drain plug had to be 'easi outed'- and a lot of sludge on the magnetic pick-up)

If its worth doing any idea how much the plates cost ? or what is the bearing number (i.e not the GG part number)

I've also seen 'water pump mod', but can't see any part numbers that have changed.

Finally does the radiator cap really need to be turned clockwise to remove as it shows on the cap ?

Just a new boy finding his way

The 04's came with a different clutch basket and different clutch plates. The only way to improve your clutch is to buy the whole basket
