    Did a quick search on google, but couldn't find an answer what is hydraulic release bearing (as in why use it and what is it good for)?

    if you have a hydraulic clutch fork setup like most bmws it has a slave cylinder on the outside of the bellhousing/gearbox and it pushes on a frok that pushes the thrust bearing to make the clutch work.

    like this

    now the hydraulic release bearing sits on the shaft and the fluid pushes the bearing out to make the clutch work

    like the pic in my last post.

    some of the reasons you would use it ......no room in the tunnel for the clutch slave and fork,.....cant find slave and fors for your bearbox...or like me you have a auto bell housing that doesn't have a hole for the fork or mount for the slave cyilinder and you cant find the fork setup anywhere to buy so easy option ......howe release bearing from summit racing landed for $208 and spend $60 at safe are brakes getting to lines made up..

    1 flexi line coming from the clutch line into the release bearing.

    2. one hard line from the bleed nipple to the outside on the bellhousing so you can bleed the bearing from outside.

    that's about it.

    If you are well versed in tearing down, reassembling and most importantly resetting a diff, then it would be no problem.

    The resetting is the part that is beyond me, setting pinion depth, bearing preload, backlash etc....

    And this will all be affected if you change the centre, as it may sit differently in the side bearings, and the crownwheel offset may differ. All very minutely of course.

    no all im wanting to do is keep the same centre LSD and just remove the .3.9 crown and pinion set and change it to others as I want them.

    I know the crush tube can be a pain but I was just going to mark the nut and count the turns to take it off and put it back the same.

    but my question is will all 188mm crown and pinion sets work.?

    The LSD centre can be 'swapped' between any Medium Case Diff (typ 188).

    BUT, it is not quite as simple as unbolt the crown wheel and stick another crown wheel on it and away you go.

    As all the bearings will need to be adjusted to suit, which I wouldn't DiY.

    so its not a case off pulling my diff apart changing the pinion gear, changing the crown wheel and putting it back

    as it came apart .?

    sorry not trying to be funny mate as I do take all the advise you give me on board its just I havnt played with ones of these diffs(well apart from locking them).

    put I have pulled apart and rebuild a lot of other diffs in the past.

    sorry if this isn't in the right place.

    but ive got a e30 med case 3.9 lsd and im just wanting to know what other

    model crown wheel and pinions will bolt to my lsd carrier.

    its for my race car and I cant afford a heap of lsd diffs so im just wanting to get a few other ratio

    crown and pinion sets.

    thanks for any help.
