272-312 Y-block crankshaft keyways
On the front end of the crankshaft there are two woodruff keyways. One for the timing chain gear, the other for the damper pulley.
Question: Are they in line with each other, 90* or 180* degrees apart, or something else? I have one here I was going to look at without having to ask, but can't get the damper pulley bolt undone to get the pulley & timing cover off, until I get a bigger impact wrench. |

If the engine is in the car, put on a socket and an arm against the right side frame rail and hit the starter. If the engine is on a stand, remove the oil pan and use a long hammer handle or a stick of wood to hold a crank throw.

After I pull the pan in the next few days I might run the crank and block down to the machine shop and see if it's still usable. The pistons are stamped '060' on top. If it needs to be bored I'm guessing the block may be done??? Hopefully the crank & rods are still ok. I thought it was a 292 until the crank turned over and showed the 312 dot on the flange. Thanks! |
