Clocking VNT BV39 turbo - plenty of pics but no idea....

Is the pressure of that center piece the only thing the orients the vane assembly

nah read again...

I toyed with all sorts of methods then used a bit of acetate with concentric circles printed on it to mark up the new positions for the locating dowels for vane assembly and housing.

the vane assembly and the outer housing are both pinned, I also had to drill a drain hole? in the cast section.

Built up the vane operating mechanism on the turbo and concocted a messy manifold to fit the pressure and oil temp senders, I've since decided it was rubbish and got some decent fittings from local hose specialist - he was very helpful and gave me a really good cash price

i read your post on clocking the bv turbo. i got a bv43a which needs clocking and looks the same as yours. do i need to buy those bits from china or can i reuse mine. it unscrews anti clockwise with your special washer tool?

grateful for any help
