question about crankshaft nose

[burn_your_money]

There is less chance of running into problems with the v-belt system. Are you planning on using the AC?

hello. thank you for response. no i don't have a/c.

now i've got one more question. my original pulley had two seats, one for v belt and another for v ribbed belt.

like in this picture. i'm going to run setup like it is shown in the picture above. so which will be better, two "v belts" or one "v ribbed"  and one "v belt".   as i have found out for me it would be easier to use original pulley (one "v ribbed" and one "v belt"). because my original alternator has a pulley designed for v ribbed belt and i wouldn't
 have to change it.


if my original pulley works the same way as the one i have bought yesterday (pulley with two v belt seats) than i can take it to the seller and get my original one any time.

but, if running v ribbed type belt will cause problems i will keep v belt pulley.   

also original pulley is a little bit heavier than the one i have now, but there is not a big difference

need your opinions one more time.

If by v-ribbed you mean a serpentine belt then using it would greatly increase the chances of the crank nose failing.

ok, tahnk you so much for your help. at first when you used phrase "sept belt", i thought that you meant using only one belt for the whole engine... 

than in wikpedia i found that serpantine belt stands for v ribbed belt and everything became clear. i will keep my new pulley and use two v belts.  thank u for support

No problem. Good luck with it.

You should check the cam to crank timing regularly to make sure that it isn`t moving.

I'm putting a 1.9 in my samurai...it has a 1.6 already..The crank nose is perfect but I am still going to have the nose machined..piece of mind

Well he plans to rebuild the engine soon. To me it sounds like he wants to just test the engine out and make sure that it gives him what he is looking for before he dumps a bunch of money into it. He is aware of the problem and isn't running serp belts so as long as he keeps an eye on it he should be safe until he does the rebuild.

isnt it fairly cheap to get the crank broached tho? i would just do something like that.

My understanding is that the 1.6 RARELY suffers from the crank nose slippage unlike its big brother the AAZ. The issue is caused by the heavy load the serpentine belt puts on it along with the vibration & load changes coming off of the alternator.

im not worried about my AAZ crank nose because im running only 1 V-belt - no serp - no power steering - no AC.

yesterday i have ordered new crank bolt from germany, genuine audi/vw part (4 dolars including shipping). i'll have my diesel suzuki vitara started for the first time in 1-2 weeks looking forward to hearing the engine sound  my goal is 15-20K kilometers with this engine.... then further modifications will take place  at firs i have to test how my home made adapter plate will work (hope that it wont cause any trouble.... )

today i was called that my crank bolt had at last arrived from us. i picked it up adn started toghtening it ... as it is written in vw manual i have tightened it 90 NM. but after that i couldnt tighten it more than 45 degrees (90 degrees is written in manual)... at that point i had a feeling that something would snap if i continued 

this is the photo, hope it works

here are the marks highlighted. i think it is 50-60 degrees, not more...
