Bedding in new clutch

[suubyduuby]

Just got a new HD clutch (factory replacement) in my '99 BH5 wagon.

Wow - compared to the old one (which was slipping), sure bites like nothing on earth.

However, she shudders a fair bit when taking off in 1st/reverse. Slightly higher rev's ease the takeoff, but still feel's pretty on/off and tends to bite fairly aggressively. Have been recommended to give a good week to bed in - but just wondering what I can do to ease it in?

Apart from taking off from a standstill, feels pretty mint and responsive.

Just shudders a fair bit when taking off.

Would be interested in anyone comments who's put in/running something similiar.

Any advice for getting things a bit more smoother would be keen to hear. :

why did you HD?

Factory clutches have enough probs with shudder as it is

[Guest]

why not?

standard IS a HD Exceedy clutch anyway? aint it?

I just drove mine (few years back now)

Factory (turbo) clutch is FINE.

I have track tested with 250kw atw, no slippage at all

30,000km of shear track abuse and the V5 is still going strong

Yes factory is Exedy - but what is HD? besides heavy duty

9 out of 10 clutch issues I have seen are non O/E

225mm and 230mm for Sti

Heavy duty and 220mm? off top of head?

The old factory clutch did shudder a fair bit when cold, but believe this was quite a common occurrence.

Feel of the new clutch is great, just keen to know how I can best bed it in over the next week.

Obviously you want to avoid hard launches (which I don't make a habit of anyway)...but what's the best way to drive it while's she's bedding in?

[Guest]

bedding in = drive it normally and dont be a dorkus No launching, flat shifting, etc just normal driving

Preloading the top lateral engine mount helps to some degree

Thanks Ichi Ban, makes good sense.

Normally round town take off smoothly with minimal revs, but doing this with the new clutch shudders quite a bit. Easing out with revs around 1.5-2k feels a bit smoother. OK to keep doing this while bedding in?

(Isn't quite as smooth as before, but seems to avoid shuddering as much).

could make the issue worse in the long run by doing higher rpm take-offs now

se the mechanic who fitted it and ask for it to be fixied

couls be a loose mount, bets get it checked and issue logged with the shop now
