Thread: speedi sleeve Q

Regarding Q2: The speedisleeve instructions do say to fill deep grooves before use - epoxy is one recommendation.

But the destruction of the speedisleeve is something else. I use to destroy seals because of the heat buildup - too much preload on the bearings. Could it be that the bearings are getting too hot, cooking the seal, making it harden and grind the speedisleeve?

I'd try putting another speedisleeve on the old hub - with metal filler - (and maybe having the new/another hub as a spare) and trying again with preload according to RAVE. Then, a couple of months down the track, say with the next oil change, pulling the hub and seeing how the hub is.

i have been doing bearings up the same way for years, don't think i have an issue with too much preload. i regularly feel the temp of my hubs when i pull up and have never noticed high temps

i put new bearing in when i upgraded to maxi axle 3 years ago

had a good look at the bearings and they are in top nic, i think they must be enjoying being lubed with oil

i might pick up a new stub tham play around with the old stub....and as you say i can than throw it in as a spare

I was reading something a while back where a lot of places wont use speedi sleeves in what they term 'dirty environments' diff pinions were specifically mentioned, maybe stub axles would be the same. This was due to the dirt getting in and rapidly wearing the speedi sleeve which then caused almost instant failure of the seal.

I could see this being a real problem with an oil seal but maybe not so drastic with a grease seal.

yep there was a lot of crap in and around the stub and the outside of the seal

Check to see if the seal track is replaceable. On my series 3 the whole track will come off the stub axle and is replaceable with a new one , however on my td5 def. it appears to be all one piece.

I recall spending hours polishing the seal surface on an old series 2 with wet & dry back in my younger days. Things tended to be done on the cheap a bit more then.

No, they scrapped the replaceable seal track before the end of S3 production!

Where do you get speedi sleeves from?
