Crankshaft bolt tightening

I have a disc 4 and in the process of talking up the crankshaft bolt. I have read somewhere on this forum that you can use the timing tool on the flexplate to hold the crankshaft, is this correct. The torque is 300Nm plus 90 degrees and the flexplate does seem a little flimsy, can anybody confirm?

Are you sure it is 300Nm + 90 deg ? On my D3 I'm pretty sure it was 100 Nm + 90 deg, and that was b**** y tight.... Laughing The Laser locking pin that I used in the flex plate worked fine for me, the flex plate is stronger than it looks.

It should be 100nm plus 90 deg. And yes the tool will hold it.

look at https://1drv.ms/b/s!AnHBx4Wc2MJLh7wuVLCOAJ_Kz6WP8A?e=2eSZK9 (Citroen Workshop Manual)

It's in Italian, Pag 38, item n° 39 "Pignone di distribuzione sull’albero motore" = crank pulley bolt

NOTE! (french peoples...) torques values are in daNm (1 daNm = 10 Nm)
