    Bolt up the cylinders to the upper crankcase half then flip the motor over so the top of the cylinders are on the workbench. This way when you drop in the crank the rods have a place to go and you can line the bearings up and the motor will not tip or fall over. After the pins are lined up then yamabond the two halfs drop the lower case half on and bolt up

    Chances are if you didn't get them dead on then you pushed the pins into the case. If it was me I would pull it apart and check to make sure you didn't do that. The reason is if the bearings are not lined up right then the oil holes will not line up. If you did push the pins in then green locktite will hold the bearings in place. Also heard if you pushed the pins in then the crank should be rebuilt do to the force put on them.

    They are in the holes of the block and bearing I used the sharpie mark to help me line them up so I could seat the pins.

    marking each 90 deg from the pin will work .. (this helps in verifying its seated fully) ..

    Anyone thats worked horizontal VW's will mark up their 'solid' bearings with sharpie indicators..( the VW pin is pressed in the block, not the babbet, so you have to float the 3 various diam. circle bearings around till the crank seats..)

    I had 1 WR with a pin crushed flat...when tightened, it cracked a piece of the support web ..luckily where it busted didnt affect the motors use, the piece was still partialy attached...
