I know this is an old thread but anyway.... My 4k alternator has the coils mounted on the front housing whereas the VL has the coils sitting in the rear housing.

Also I can not un bolt the god damn centre shaft because the bolt heads are on the inside of the housing. WTF? It's like the shaft was pressed together after it was bolted in. (on the 4k)

Might try to drill the bolts out. Had no problems pulling apart the VL alternator.

It's clicked now..... You didn't remove the bearing carrier.

if i remember correctly you just tap the rotor out from the front bearing?
