Hi my pedal clutch on my ST170 has just got very high and im getting abit of clutch judder every now and then when i pull away.
what size is the st170 clutch? i know its more less a zetec engine... and you can bolt a rs turbo clutch to a zetec flywheel, does anyone know if you can on a st170? (have an uprated 220mm clutch for cvh)

doubt it as the spline is pretty huge on the st170 gearbox

 

The ST170 has a unique DMF and clutch to suit its Getrag gearbox. Depending on month/year of manufacture the clutch is 230mm or 240mm (changed mid 2003).

It is possible to get a non-DM flywheel from UK or many US sources with suitable clutches (230mm), but the cost is similar to a full Ford DMF/clutch.

cheers martin good info (dont have the foggest about the focus i just drive it lol)

 

but once you have changed the dual mass flywheel for none dual mass if you ever need to change the clutch again its no more exspensive than any other car

 

i just did this change 3 fecking times because the crank seal was letting oil in to the DMF and the garage failed to spot it! could be worth doing it at the same time as the 'box is off anyway as it's "only" a Ł50ish part...

 

botters to some extent, yes. Unfortunately, as the Getrag splines aren't too common, it makes the clutch a low volume item made even worse by a variety of plate diameters and sprung/unsprung hubs across cars that used it (Vauxhall LET20, XE20 in Calibra turbo 4x4, ST170, BMW/Mini Cooper S). So the cost of the clutch kit is still 'premium'.

Also many of the American alloy flywheels are too light for the 2 layshaft box. Causes it to rattle in neutral, though a thicker oil can reduce it.

The UK flywheel/clutch is sourced from Helix, and as I understand it uses a TTV steel flywheel and Sach clutch - organic or paddle.

alexst0ne Sounds as bad as my experience on a clutch replacement I had to have done at a Ford dealer (lease company car). Usually delays (3 days to decide the clutch was gone after it was towed in), then broke a SPAX front strut, gave it back with bad idle (some of the vacuum lines on undrilled nozzles, others left open), and finally stopped on the road (due to all the swarf not cleaned out accumulating on the CPS).
