how long to cook a ring gear / freeze a flywheel?
MikeR - 28/5/06 at 02:02 PM

Had mine in the oven (210 degrees) and freezer for 40 minutes now.

Pretty sure the ring gear is "done" but what about the flywheel? infra red guess the temp says its only around 2 degrees and not -5 to -10 i'm hoping for

We chill big valve inserts with a bucket and CO2 fire extinguisher. Can you 'borrow' a fire extinguisher from some unsuspecting emporium??

only had to do the ring gear when i did my xe flywheel. think it was in on max for about an hour and a very big hammer

infra red thermometer are not that good if the surface is shiney
electrical tape stuck on is a good compromise to get a better reading

Don't put it on the wrong way round.

It's a bit late now, but why didn't you put the flywheel in last night?

hmm, well the 4 haynes manuals i read suggested that 200 degrees is the correct amount (ok, one said 220 so i'm doing 215!)

Got it in the fan oven so make sure the heating is even.

(boy i'm glad i'm single, spent the afternoon with those two bits in different kitchen appliences while watching the GP - txt'd a female friend and she just laughed at me and she's a petrol head)

The wife's asking if you asked her when the next harry potter book will be out.

In reply to the post I did a xflow ring gear years ago in a log burning stove for 20 mins and it went on ok. I did;nt chill the flywheel at all.

LOL I knew what you meant.
Good luck with the ring gear,

just had 30 mins at 270 as 215 didn't work. flywheel back in the freezer (running at max & forced to always run)

STILL DIDN'T FIT!

Didn't drop on, tried hammering it and no joy. Looks like i'm off to the machine shop to let them do it.

If the flywheel is cold and the ring gear is warm it should just drop straight on. No big hammer should be required! The problem starts when you get it half way!


I used 638 Loctite as well.

In fact if you do the calcs you would find out that just 638 will hold a ring gear but I do not know anybody brave enough to just trust Loctite!

We did one a while ago and kept it warm with a propane torch, just a blowlamp type, after it was placed on the flywheel which hadn't been cooled. It did need tapping on but it didn't take much effort. Don't keep the heat in one place for too long and you should be alright

Krismc - 29/5/06 at 08:47 PM

Took mine too MNR with a fresh crisp £20 note! and the ring gear just jumped on by its self while i was away

And the £20 probs turned into beer!!

Got a machine shop that will do it for a tenner - its just getting it to them is the problem, wrong side of town, work in a different town, opening hours etc.
