SKF Speedi-Sleeve

[HSGB]

Hello,

My vintage compressor, after removing the stupidly heavy, cast-iron flywheel in order to access the crank seal, I found this:

The felt oil seal has worn a couple of grooves in the crank, that's why all the oil has been weeping out. The old felt seal goes in this small, iron housing:

What I want to know is, has anyone ever used, with success, one of these SKF speedy-sleeves? I never have, but would like to hear from anyone who has. It seems a simple fix but, is it worth trying, or just a gimmick? One other thing. It mentions about modern, rubber lipped seals but, mine has a felt seal, so I do not know if the felt will damage the sleeve. If my lathe was running I reckon it would be easy to machine the housing out so that it could take a modern rubber seal.

Yes, successfully used Speedi Sleeves on various Land Rover parts.
Diff Pinions particularly.
Felt seal won't harm the Speedi Sleeve.

I've used them on industrial pumps in the (working) past .
A good product.

Ah, that's good to hear, cheers! I have bought one now, not cheap by any means. What I am concerned about now, is that the crank is so worn that I will tap it on and it will just fall into the damaged part and not be concentric to the crankshaft. I have bought some Loctite 660 to build up the damaged area but, that's meant to be uncured when the sleeve it installed so, it won't really help stopping the sleeve dipping into the grooves. The sleeve is only 9.5mm wide so, I am hoping it will just span the damaged part, if it doesn't, then I might be in bother.

Build up the damaged area first?

As long as you have enough good area for the 660 to do its job then anything that holds the sleave in place will do,

You could even use the 660 to fill in the gaps if you are not in a hurry

Or, another way (looks like you have good access around the shaft)
Install the sleeve, put 3 lengths of round bar evenly spaced around the shaft running lengthways and over the sleeve. Tape or cable tie in place while it sets.

If my lathe was running

I’d sort that before tackling any other jobs…

...that's meant to be uncured when the sleeve it installed so, it won't really help stopping the sleeve dipping into the grooves.

I think you might be slightly misinterpreting the loctite blurb and perhaps worrying unnecessarily.

This says it remains uncured _outside_ the joint (i.e. exposed to the air) so what remains beneath the sleeve will harden to bridge the gap:

From what I know, being in contact with a metallic surface is what catalyses the loctite causing it to herden faster than when just in air.

I have seen people fill the recess in the shaft with JB Weld, machine/sand/file back to nominal diameter and then install the sleeve over that. If that works, a proper loctite product designed to do the same job will surely work better.
