Title: What size is the crank pully bolt?
Post by: Jay on November 14, 2009, 02:28:03 am
I've done a search (can't find the size of the bolt) and need to know ASAP so I can get the correct size while I'm out.

It has a 19mm 12pt head and is found at your local dealer.

Thanks! I bought one from the local(ish) Halfords (lucky my bro in law was here to drive me there), even though I ended up pushing her in gear to get the water out and it worked a treat. At first water was pouring out, then squirting out then just air was coming out and it sounded like a steam train  ;D chooka chooka chooka chooka chooo chooo   ;D

It's a special torque-to-yield bolt specifically designed for the large amount of torque required to hold everything together...hopefully they sold you the right one.

Oh, I just bought a standard 12pt 19mm one :( I just won't use it on the crank pullet bolt if you say it won't work properly.

If it comes loose for any reason the engine will grenade... so my personal approach is to get this specific part directly from an OEM VW supplier or VW themselves.

Cool (http://www.golfgtiforum.co.uk/Smileys/modern/afro.gif) I'll have to invest in one of those one day and not touch the crank pulley bolt with a standard 12pt.

I planned on ordering one to upgrade my 6pt. 

Part # or year application..  same as gasser?  I don't want them getting me another 6 pt.

I think the 6pt has been superceded to the 12pt. The guy at the counter should know... should is the key word though

my 1.5 has a 6 pt 17mm bolt holding the crank sprocket on. my 1.6TD mf engine has a 6 pt 19mm bolt. none of my engines have the 12 pt bolt. are they all too old for it?

Hey, maybe it's just me but I think there's 2 different conversations going on here?  One about someone asking what size SOCKET they should be getting, another talking about what bolt to use?

Kinda 2 conversations.  The earlier 6 pt. 17mm bolt has been superseded by a newer, stretch style 12 pt. 19mm bolt.  I found the answer to my question.

Ah yes, so there seems to be  ;D

My bad I do apologise for confusing the situation, I was in a rush to post this and go out and have a look at the engine. I was after the socket size, not the actual bolt  :-[ 

So it is safe to use a 12pt socket on the bolt to turn the engine over by hand after all?

That's common procedure.

Thought so. Like I said it was my own idiocy in haste to get the post up.
After 9 years using forums you'd expect me to know better  ::)
