Crankshaft Timing Gear Wear

[Harrison Kotrolos 33]

Hi all,

 

Throwing it out there before I make the trip to engine builders. Is this crankshaft serviceable? 
 

Looks like it had a previous life of burnouts. The keyway was half squashed and the timing gear had play to wear the crank down.

 

Am on the hunt to replace my bent crankshaft

is it some rare crank?
it's probably going to cost more than finding another, but there's ways things like that can usually be fixed to My understanding but the time/$$  would add up faster than the cost of another crank.

Nothing rare. Am trying to source another crank for my engine as the snub on it got bent.

The block is an earlier one with the two-piece rear seal and flange on the crank, which I'm finding hard to replace, I have 3 newer cranks with the small and large rear main seal.

Can I use later cranks in the earlier block? (I.e the single rear seal in a two piece seal block?)

i believe the later ones (same size journals as EF 4.0 etc ) are smaller, so not usable.

 

assuming you mean a 250 crossflow, i can't remember ever person's project off the top of My head.

My bad, it is indeed a 250 crossflow.

Got a few more engines I'm hunting down, but may need to take the approach on redoing a whole new block to suit the cranks I have.

Unless someone on the forums has a earlier, flange crankshaft for a 250 crossflow lying around

make a wanted post, but generally either finding wreckers engines or facebook is usually the easiest way.
the forums are pretty slow for ads generally. especially for something as heavy as a crank to pack and send safely. 
some engine reconditioners might have spare cranks sitting on shelves for 20yrs if they'd been around for long enough.

I have a complete running crossflow from a Bronco, if you are interested.
