Skoda Octavia 1.6 diesel crankshaft bolt torque

[Dcal]

Hi all.
I am doing a cam belt service for a mate on his 2017 Octavia and while I was in there I discovered it need a front oil seal.
Simple job when I was this far in, but on trying to get the torque setting for the crank shaft pulley bolt, I'm getting different settings.
It's got the DDYA engine and the 12 sided bolt.

Is it - replace the bolt, 150Nm then 180 degrees?

I took it off with an impact gun and it didn't seem that tight, but someone has been in before me to change a water pump under warranty. (I could tell by the damage to the top cam belt cover)

AutoData says for your 1.6CR DDYA engine

Crankshaft pulley/damper centre bolt	​ ​ 180 Nm+90°+45°​
Use new bolts.

Crankshaft pulley/damper bolts	​ ​ M8x20 mm=10 Nm+90° M8x50 mm=20 Nm+180°​
Use new bolts.

Thanks @premmington
I'll get bolts ordered on Monday

I'll need to make a tool to hold the pulley with that torque!

Or take the starter out - and jam up the flywheel teeth.

Used ton stick Caterham in gear have the other half on the brake pedal.

When I suggested this solution on the owners forum, a well known engine builder said that was a bad idea due to the torque.

I mentioned his claim of the same engine built by him with considerably more torque produced...

Silence...

Built my own engine

If you do make a crankshaft "holding tool" up - make one that fits on the crankshaft directely - not the outer pulley that holds on with M8 bolts (as you don't wanna be snapping/stretching them).

If you gonna do this on your own - with no second helper to "jam flywheel up" with a prybar.

Making a small tool to go off starter motor mount bolts and hold into flywheel teeth is just easier - than making a crankshaft holding tool that needs to be long enough to hit the floor to stay still - while you touque up the bolt.

Bought the proper (Chinese copy) tool for the Freelander 2.

Snapped it
