Saving Old Seagulls

Hi,
Can anybody come up with any magical ideas for removing a Anzani Pilot flywheel
the little blighter just wont budge even with a 2 legged puller
I have removed dozens of Seagull flywheels in the past but this little chap is
certainly a challenge (Don't want to use the EBH) as I fear damaging it and
replacements don't come easy
Hears hoping

If it's not working with a puller, it doesn't sound good, as long as you are pulling as close to the centre of the flywheel as possible, so you don't deform the flywheel.
I don't think using the four screw holes on the flywheel wouldn't help, what I would do, after liberal lubrication hasn't worked and I have to use a puller, I do it up as tight as I can and shock the flywheel with a hide hammer, probably what you are already doing.
Heat is not a practical option, a penetration or freeze spray may help, sometimes you have to be heavy handed.

Hi Keith,
Thank you for your reply I think I shall look for a better puller, one that I can get closer to the crank with
the one I am using at present is probably flexing the flywheel and defeating the object,
Have you any preference in lubricating fluid, the best one I have ever used was PB Blaster but seems it is
only available from USA and while it is not that dear the postage at £20 plus is a bit silly
Thank you once again
Ken.

Have you any preference in lubricating fluid.

I don't know if I should answer that.
I use the common or garden stuff WD and the likes, as its a penetrating fluid not so much a lubricant, I prefer Plusgas myself.

Hi,

What about using acetone as an agent that will deliver the penetration oil to the area of the problem?

I have read about people mixing acetone with automatic transmission fluid etc. I believe a solution of an oil that dissolves in acetone could work.

For the mixture above I read 1:1 ratio. A little bit of search on the web in this direction and experimenting may bring the desired results.

Don't repair it. Send it to me, i need a con rod!

All jokes aside, mine was a right pain to remove also. Did as Stelios suggested, filling the area around the nut with WD40 and then Acetone for days at a time. Eventually I came off with the puller in a very load and exciting fashion. In fact the noise was such that I though I had broken the flywheel but not the case. It's all intact and in perfect condition.

Use a 2 pronged puller only. Do no use the screw holes.

PS: See Anzani Pilot resto thread. Re-assembly will commence once I have the con rod repaired or replaced.

Regards,

I had the same problem on an suspicious flywheel for distortion. There was no need to be gentle. So after a couple of days of soaking and no luck I took out the drill bits and the taps...

I suspect that you wouldn't like to tap on a flywheel that may be difficult to find a replacement, but it is still a solution. With this trick, mine pop off for no effort. If you do a neat job may tapping be acceptable. I used M6 as the bolt seller made a mistake and gave me that size instead of M5 I wanted. M4 may do the job but make sure you buy high tension bolts.

Hi all
Many thanks to all who answered my problem the little blighter popped of this
dinnertime after soakings of lots of acetone and transmission fluid, a 2 legged puller
and a monster EBH.
Thanks again

Hello Cheshre, how about some photos?

Let's see this little Pilot of yours.
