 |
|
I have a crank out of a friends motor that i tore apart, It was a bone stock 1600 dual port. I've never seen a crank that looks like this one, the texture is strange compared to other stock VW cranks i've seen. Just wondered if it was a cast replacement crank or what, it has a vw stamp on it too. It looks to be in good shape though.
those markings on the side look odd to me

it is stock forged crank
ugly sucker too, but that does not hurt it any, just don't enter it in any beauty contests
at one point must have been all rusty, that is what the acne scars on the sides of the web are, but it was shot blasted(or similar process) at some point and that got rid of the rust and gave it that matte finish |

No man. Just imprint this crank features in your head. These are the bone-stock VW forgings.
You will be able to tell in the dark which is Chinese and German VW crank shortly. |

 VW only used forged cranks in their air cooled engines. |

thanks for the replies, the engine it came from was pretty much bone stock but my reason for concern was because the rear main case bore was beat and the bearing was loose in the case. I don't know what would cause the thrust bearing to beat the case other than a crappy line bore/poor bearing crush or a cracked crank vibrating like crazy.
this is one half of the case after a line bore to .060" you can see the ridge in the middle and the beat thrust surface

| Looks like the next linebore is overdue. Or a 411 mains waiting to come out. |

Looks like a good argument for the "Heavier Pulley".

Plenty of engines have cast iron cranks that are perfectly reliable for their intended use. Just because the Germans didn't know how to make a quality cast iron crank in the 1930s, doesn't mean the Mexicans couldn't do it in the 1990s.

cast cranks have their place, and each cast and forged have their advantages over the other...
