If it is replaced or the newer one it is a TTY stretch type and only supposed to be used 1 time. Older one I forget, but I was thinking alot of guys here do 242 loctite and run it in with an impact.
The TTY bolt I believe was something like 140 FT LBs plus a 1/4 turn.

crankshaft sprocket to crankshaft (lubricated)

6-sided bolt with washer 137
head head bolt with washer 111
12 sided bolt with collar 44 + 1/4 turn

Those are foot pounds

Okay thanks y'all. I used to just do it some locktite and the impact gun, but since the whole 1.9 crank fiasco, i figure it's better to do it right. VW cranks are not industrucible !

I wish Bentley Publishers knew what they were doing. I was also using my 85-92 Bentley

Just for anyone who cares: we locktite'd [?] the bolt and pulley inset, torqued it to 66 ft/lbs, really didn't seem to want more than that,  and  then just tried to give it 1/4-1/2 turn. It went about 1/3 rd of a turn. Should be fine.

I was wondering about that.  I was using data from section 3 page 44. section 8 Engine technical data.  Mine seems to have been printed about 3/92.
