[Vwdiesel] Cheapo rebuild--Crankshaft

[Dave Cook]

At this point I am starting the doubt the feasability of my goal of getting the engine together this weekend.

I have three engines in the garage:

1) Original in the car, threw the rod.

2) Mostly complete, planning to rebuild. Engine code is from a Rabbit

3) Longblock, engine code from a Vanagon

I got #2 mostly torn down preparing to clean up the block, paint it, and hone the cylinders.  This was slowed by an eye infection and a broken water pump bolt but both those things are being taken care of/taken care of.

I pulled the sprocket off #2 to discover that the woodruff keyway has been damaged both in the sprocket and in the crank.

So what to do?

As you could see in the pics, the crank is damaged at least some in the in-car motor.  I was not planning to tear that apart until it was time to transfer parts to the new motor, for ease of remembering where everything goes.  

I had basically nixed the Vanagon block (#3), thinking that this particular engine had worked really hard pushing the Vanagon around until the valve embedded itself into the head. 

What I'm wondering about is if the Vanagon crank would have taken much of the damage, or if it would have been in the bearings?  

I presume that it would be a bad idea to use the Vanagon crank in #2 with #2's bearings.  So if I was going to use the Vanagon crank I would want to use new bearings to put them together.  Right?

I haven't gotten the crank all the way out of the block yet, but the main bearings were looking ok overall so I was hoping to get away without having to replace them.

Thoughts?


Thanks,
  
Dave Cook
