By how much, a little or a lot ?

Maybe use some brake cleaner after a quick sand using emery paper.

Edit, do you mean all the crank holes line up but dowl still doesnt?

The crank dowel doesn't line up on te lightened flywheel, when attempting to tap it on (wood and Irish screwdriver) it is catching the inside of the dowel and burring it,
If you look at the two side by side its ever so slightly noticible,
When I get back to the car ill get my measurements off the vernier
Bearing in mind this was bought second hand and 'fitted to previous engines' with pics I'm a bit baffled
I've a couple of ideas in my head but anyone else got any b4 I mention them??

Kinda p'd off too as I wanted to get the lump in today so I could start building the bodies and bay back up Thumbs down

Is your dowel damaged? Perhaps peened over or distorted?

Got another you can try off say, another engine?

Alternatively removing the dowel, offering the flywheel up and establishing with a drill bit or whatever that the two holes align. If they do you could try gently inserting the dowel.

Soz Jeffers was abit distraught and p**sed off y'day
No it's not the dowel, it fits std flywheel not a problem!!
And bollox if I'm swappin the crank!!!
I either send the flywheel to an engineering place to have the hole elongated and poss rebalanced, or a take my ickle grinder and shave a wee bit've flesh off the top of the dowel to slide it on but keep the dowel??? Opinions please Cry

As above, remove the dowel, bolt flywheel up and check if the holes line up Thumbs up

If they do your dowel is damaged, either replace or get it machined down Yes

Never had this problem, although I do remember the lightened flywheels being a fairly tight fit on the crank dowels, but nothing a small tap didn't sort out.

Fairly tights like saying the popes a little catholic in faith......
Might skim a bit off the dowel with the mini grinder, I got a dowel on my old lump if I give up and I go std flywheel...... (Which won't happen FYI ) as I'm not up fr modifying the flywheel and messing up balancing

The little tap did nowt either

In that case then you definitely have an issue somewhere. Yes

I have fitted a few of these in my time now and it's never taken more than 2 minutes per time to get the flywheel fitted on that dowel. Smile

Something isn't right here. My flywheel was second hand and I got it straight on my engine no problem. It was a little snug on the dowel but it went on without bother, I didn't even need to tap mine home.

I think you should remove the dowel as I said before, then fit the flywheel bolts loosely, and try to slot a drill bit or similar through both. Your dowe l must surely be damaged, especially given your flywheel has come off an engine.

For clarity, I am ssuming you're using a Rich_W flywheel? Or are you fitting some sort of standard one that's been machined?

Glad you've resolved the issue, but really can't think what the problem was in the first place.
