Hurricane offset tool/secondary hub machining

[waldo1]

just did this - what a bitch! who said do it every year as maint.??? noo - looks to me like that bearing was installed that way - 1mm short - because when u remove it - when installing with loctite, bearing bottoms on the backside of housing while pushing it with something flat - i had to find a special diameter piece the size of outer race to get it that extra mm - i think its like that from the factory. id like to check a non belt blown sled or a new one. thats a hard way to get a mm... im gona slide hammer the next one home - in 5 minutes instead of hours....

Thanks for the info Knapp, I'll attach some pics but It looks like it did move in to me. Also looks like the clutch was not properly torqued down and spun on the shaft at some time.

Makes me wonder if at some point in time, someone couldn't get the clutch off so they did what allot of people did in the "old days" which was tighten up the puller and then hit it good with a heavy hammer which moved the bearing and snub in the housing? That would also explain the damage to the end of the splines. The two splines are designed to float on each other but when the snub got moved in the splines bottomed. One more hit with a hammer and the end of the splines were chipped.
IMO, based on how this is designed and held, do not ever hit the end of the puller or crank snub as you could move the whole works inward.

Very possible they did bottom out, but most I have seen the clutch will hit the 4 bolts on the bearing housing before bottoming out.
More than likely there was a sharp edge on the spline shaft from machining causing a stress riser. That’s why I say polish the jagged edge before reassembling. It’s similar to a piece of glass with the corner broken off, it will continue to form cracks unless smoothed over.

Not a good scenario either way. Bottom line to me is don't hit the end of the puller with a hammer. Nothing might happen (other than have clutch pop off) but some bad things might happen. If it won't come off, use the "hydraulic" methods.
