nc2 5.0 socket size for crank bolt needed, im doing the harmonic balancer and 23 mm socket is too small 1,1/4 too big, what size is it ????? so i can go buy one .seen threads on hm bal but no sizes for 5.0 windsor.bolt. TA

and ,if it wasnt for a commodore road hog, a falcon would have won bathurst in 2012 ,as it was the faster car hehe

you sure 23mm is too small? i thought it was 18mm.

yep tried to measure with some small multigrips, and imprint on some gaffa i est; 24.5/25mm my eb2 4.0 is that smaller size.

24MM socket and 22mm on the 6 cylinders.

It's 15/16" end of story.

yes , the super cheap guy fitted a 15/16 long socket for $5.99, and then i used a 1/2 inch imperial socket on the 4 pulley bolts while the belt is still on, by loosening the crank bolt by turning over the motor slightly while a fixed 1/2 driver onto the cross bar (black rectangular), then with 2 x 3/8 bsw set screws on my harmonic ballancer removal tool (hbrt),(4 wouldnt fit) and a rachet 17 ring spanner on it(hbrt) , undo the crank bolt some, then alternating with undoing the crank bolt some more and the hbrt, until out, oil both sides of the new one ,leave or replace the silicone on the keyway(factory trick) ,refit, i put my hammer handly unto the gap in the ballancer out under the alternator ,did up till tight ,then got some metre long square tube over my socket drive ,and continued to tighten 1/3 of a turn each time till very much tighter ,removed tools and hammer ,put belt back on, and im having a beer now , from the start (popping bonnet) to A start up (smooth running) 1 hr 10 mins , no removing electric fans ,or radiator, just the air snorkel, for more leverage, ( no im not doing the seal)
tools used ,13/16 deep 1/2 drive socket, 1/2 3/8 drive socket , standard hbrt ,phillips,,,dip stick oil, hammer ,square tube, 2x 3/8x2 inch bsw set screws (washers and nuts)7 powerbond HB1084-N from veales on dixon road rockingham wa for the best price around $178. tell craig or russel that wayne sent you.
