Went to CBC bearings on saturday with the pulley.
The guy there said it should be fine if cleaned up/sanded.
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.Quote:

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....Quote:

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.Quote:

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.

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

Thanks, I found this:Quote:

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.
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.
When you need bearings/advice go to CBC but also go to AWB.Quote:

Handy having two nearly identical shops a short distance apart, one is usually quite a bit cheaper too.
