So I dropped my transmission today to install my clutch. While trying to put a different flywheel in there was a slight difference. Here's what I mean.

This is the stock Flywheel


And here's the after market.


There's an alignment pin on the crankshaft itself. I tried twisting it out but it wouldn't budge. And the new Flywheel does not have an alignment hole. What the hell?! What should I do?

 

1) to remove your flywheel, just wiggle it back and forth. I typically smack them with a rubber or dead blow hammer to break the rust... then it will come off.

2) What the hell flywheel is that? Return it as it looks like a cheap no-name chinese flywheel. You need that locator pin. So either get a quality flywheel. or refinish yours. Most machine shops can have it for you the same day.

 

LOL. Looks like they started on the dowel rod hole half way the drill bit broke. Then just say $%^&It!

 

Yea man that's your flywheel not the PP. If you're not going for a lighter one the cheapest option most of the time is to bring it to a machine shop and have them resurface it. Usually costs me $30. I'd trust a resurfaced OE flywheel over a new knock off brand any day

Or pony up the $$ and get a lightened fidanza or something

 

This fall I put a clutch in a stock '03 Evo 8 and I took pictures.

The second picture looks like a stock flywheel but one that has been refinished.

There was no locating pin in the crankshaft of the car I worked on, only a hole that could take a pin.

The partially drilled hole seen in both photographs here was also in the stock flywheel I saw.

The first picture is not of a stock flywheel.

BTW, there's a jawed slide hammer machine shops use to pull dowel pins.

 

Well, my question really is that why is there a alignment pin on the crankshaft? On most pictures I've seen, there is just a hole where you COULD put a pin in it.

 

Since that is not the original flywheel someone put one in there. I'd guess the flywheel you took off came with a pin in it, the hole in the crank was a little tighter and it transferred.
