Lotus Elan

Loose Flywheel

PostPost by: denicholls2 » Wed Sep 13, 2006 10:26 pm

Again, not an owner yet of the Elan. But is it really true that neither
an access plate/dust cover nor sufficient access is available through
the starter hole to let you pry the thing and determine whether it's
about to fall off? If not, seems very odd... Not much access would be
needed for this level of assurance.

If you can't get at the flywheel, how do you guys read timing marks?

Tony's right that it fits the symptoms, but I hope for your sake he's
not on the money. running a loose flywheel is sure to make for some
nasty cleanup.

Yes..you can see the flywheel when you remove the starter. But what Roger
was referring to is the lower shield that covers the bottom 1/3 of the
flywheel. It is right behind the pan. On some cars..like my crossflow in
my seven?this shield is ?cut? in a manner that allows you to remove this
shield without taking off the top bell housing bolts and moving the engine
out about ? to clear the ,for lack of a better word that I cannot think of,
locating nipples?.or bushings.. I know on my early ?lans?.it was a solid
piece?like a BIG U.



You only see a small portion of the flywheel when you remove the starter and
it would be tough to get enough leverage to see if it was loose.

My S3 SS has a section of the shield that can be slid out easily by undoing 2 small set bolts, simple. I think some s4's had this as well.

Tony,

I think you are right about it being solid across the bottom on the early 4-bolt cranks, but the later 5-bolt crank engines I believe have a removeable piece at the bottom. And the car in question is a +2, so should have 6-bolt crank. Seems like I remember one of the 1/4 bolts holds a clip which anchors the clutch tubing. I think I was wrong about 4 -1/4" bolts, that there is only 2 holding on the removeable piece.

Ah! maybe thats the noise.........the sixth bolt in a 5 bolt crank has
came loose!
Jokes aside, I don't think anyone has mentioned the possibility of a
cracked piston, it can happen and can make a loud thumping noise.

Gidday,
With a cracked or broken piston the noise is reduced or eliminated when cranking without plugs fitted.
See ya, Les.
