Vu ute clutch

Elaborate on what clutch components you replaced.....

 

The thrust bearing/carrier new overall dimension could well be the issue, as the slave cylinder is more than likely running out of travel, before total clutch disengagement's achieved.

Get under the car (don't let anyone touch or push the clutch pedal at this time), push the clutch fork back into the slave cylinder and measure the amount it travels, I'm sure you'll find it travels a fair way back into the cylinder.

There are 3 possibilities to rectify the issue:
1: Find the part number on the old release bearing & get an identical one from GM or clutch specialist.
2: There could be an upgraded release bearing carrier (that suits the newer narrow bearing) so check with GM for a suitable replacement for the bearing supplied within the kit, (hence the overall length will be identical once again to the original).
3: Is there an adjustable screw on the end of the clutch fork (inside bell housing end of the fork), if so adjust that out to give you the correct clutch operation. 2 things to be are of when adjusting the screw: 1 there is sufficient thread still left in the bell housing after adjustment is completed, 2: when the clutch is fully disengaged the fork doesn't hit the clutch cover (pressure plate).

Not sure if the VT series had/has a plastic release bearing carrier??? The older series did & they use to damage the tangs/tabs allowing the carrier to sit deeper in the fork causing all sorts of issues!

Also before you dive to far into it, check your new slave cylinder bore size & make sure they are the same as the original & that it is completely free from air in the hydraulic system!!!! Easy way to check is to pump the clutch 5 or 6 times rather quickly, if it goes into gear chances are it still has some air trapped in the system.

Good luck.
