Thread: To speedi-sleeve, or not to speedi-sleeve?

He said that if using a speedy-sleeve, you use the SAME seal - which is contrary to the advice on here. He said the seal is an interference fit and can cope with the slight difference...

I also use the same seal with a speedisleeve. The difference in diameter is nothing compared to the radial tolerances seals are built to cope with.

I have used speedie sleeves for many different applications from 650 HP cranks to RR diff flanges, always used the original seals, never had any problems.

The golden rule is to fill the groove with a high quality filler e.g. devcon f or plastic steel, allow to set correctly and smooth off with emery paper, pay particular attention to this, uneven finish will cause early seal failure

Failure to fill the groove can cause the air trapped in the groove to heat and cause premature hardening of the seal lip.:

All my Isuzu and Mitsubishi OE information must be wrong then....

So much so that they specify a modified seal for crank end seals that comes with the OE repair sleeve assy.....

Not to mention my 20 odd years with OE engine components manufacturers......

The OE repair sleeves that I've seen were far thicker than a speedisleeve. One of them was about 2mm thick, you'd never fit a stock seal over it.

Hi,

I was advised to fill the groove because the sleeve is so thin that it needs to be completely supported under the seal lip.

Don't know about the 'trapped air' theory............ the air wouldn't be any hotter than the surrounding metal.

The main thing is that they are a simple, cost effective way of reconditioning a part, if installed properly.

cheers, DL

Never had a problem with Speedi-Sleeves, they are an excellent proven product. Read the directions.

Thanks, I found this:

Speedi-Sleeve,® manufactured to precise specifications by SKF, is a thin wall shaft repair sleeve which requires no change in seal size after repair of shaft.

The guy at CBC said it is essential to use a liquid metal type filler to fill the groove.

I think the thickness of the sleeve would be a lot less than some of the grooves I have seen. So it seems reasonable that the seal could cope with that much change in diameter.
