Help!-clutch bell issues

[lykan]

So I am workign on the x-cellerator here in the house. I get it started, and semi-tuned. Something falls off.

It's whatever holds the clutch bell on I think. Its a shaft with hex hole on one end, and threaded on the other it has a sleeve on it, and a bearing, that fits into the clutch bell.

So i pick it up off the ground, put it back in the clutch bell, tighten it, thinking I'm all good. I run it in the house for about 10 seconds and it falls off again.. what am I missing?

the peices I have circled are the piece that falls out as one unit, and i insert it into the clutch bell and tighten, is this right? I can't figue out why it falls off.

this is what i have

So what I have looking from the outside (away from engine) is
#1 retainer clip on the end of the shaft. pt#200
#2 a bushing/spacer over the shaft. pt #99
#3 a bearing with a lip on it. PT#97
#4 threads on the inside of the shaft pt #95

Does this sound right?

If so why does it fall off? I would really like to run quart or two through this thing without having to "fix" anything. My boys have a total of about 5 minutes on it. Sooo anywas if anyone could help me I would appreciate it, that way I won't have to worry about it falling off in the middle of a run.

Thanks very much in advance. I been in bed for a few days (bum knees) and would really like to show my boys a good time before they go back to school monday. Any help Would be awesome and greatl;y appreciated

Your part number 95, the shaft needs to be tightened down hard.
I'm not completely up to speed on the exact engine you have but most of them work the same.

From the block you should have a Collette, a brass? coned washer, then the fly wheel, then part number 95 shaft. You will need to tighten the shaft against the flywheel. The trick is to hold the flywheel and torque the shaft as tight as possible using the correct size Allen wrench. Ofna as well as others make a tool to hold the flywheel to aid in tightening the shaft. You can use a large pair of channel locks if needed just take steps not to damage the outside edges of the flywheel. I would refrain from using any lock-tight on the shaft but that puppy needs to be tight.

Put everything back on then make sure you have no play in the bell yet everything needs to be free and smooth. If you do have play then shims or small washers are necessary under the bearing and / or under the front clip. Everything needs to line up well when the engine is installed.

Do a search on gear mesh to read about properly aliening the spur and the bell.

Not being up to speed on you exact engine, please only use my words here as a guide. I'm sure someone else on the forum is more in tuned with your engine and may be able to offer more exact info for you.

ya wat engine are u runnin'? when u put it back on can u just pull it off with ur hand really easy? I don't see y it would come off the shaft if u have part # 200. It must either be ur threads or it all isn't tight enough.
