Hello -
So I've started my first engine rebuild and I have a question: I have a 73 2.0 litre 914. On the crankshaft bearings, are there supposed to be small dowel pins holding the bearings in place? The Haynes manual shows a diagram with the dowels but they aren't mentioned in the reassembly directions. The dowels ( 4 total ) should be about 5 mm diameter by 8 mm long. Do I need them? What's the correct size? And where can I get some!? Thanks for your help! Cheers Nate Fort Collins CO 73 914 2.0 73 VW T3 Squareback |

They keep the bearings from spinning. Not sure where to get them. You might try Jake Raby.

I think aircooled.net has them. They're a standard off the shelf part, iirc.

HELL YES! You need them!!
They are actually there to align the bearings correctly in the saddles to match the oiling passages, not really to keep them from spinning- The align bore crush takes care of that.. Not only are they a must, but they also should not be longer than 8.0mm, if they are they will protrude too far into the bearing and will pich up when you torque it down and wipe out a bearing and piss you off the first time you try to fire it up! I have thousands of them if you can't find any.. |

What exactly does it look like when the crank is shuffle-pinned?
What is the advantage of this? -Britain |

Shuffle pins go around the case through bolt bores and have an interferance fit that locks the case halves together and keeps the case from "Shuffling"
We only do it for engimnes making more than 200HP. |
