Speedi Sleeve Alternative???

Have you checked on the range of the speedi sleeve as I was under the impression that when you fit them to a shaft as they are driven on they stretch and then don't require any locktite to hold them there. You might find the the 85.75 mm sleeve is designed to go on shafts up to .5mm larger.
I have never had to use speedi sleeves but I know they exist and I wouldn't hesitate to use one if necessary as they are cheaper than removing shafts and building them up and re machining..

Speedie Sleeves are made by CR Industries in the USA. There is an alternative supplier, (I think they call them Readi Sleeves or something like that) but they are just the same thing repackaged.
Pity there is not a size to fit as they work great. I am surprised that the 85.75 does not fit , as they all fall within a +/-tolerance range, as they stretch a bit.
I have used them for tailshafts and they work fantastic.
I am presuming that you are wanting to run an oil seal on a worn surface. If you can't get one, depending on how worn the shaft is, a good scrub and polish with emery with a new seal often works.
Otherwise, a peofessional respray and regrind is the only alternativeif the SS does not fit,
goodluck...

In 4wd applications we wont use "speedi sleeves' because of the amount of dirt and grit that gets into areas that have ussually created the void, where the seals runs to begin with, still gets in there when the sleeve is fitted, but instead of the seal weeping, and leaking, the speedi sleeve cuts the seal to ribbons, and becomes an instant catastrophic failure.

In clean environments though, they can be the goods to fix an issue.
