Thread: Has anyone fitted a speedi sleeve to the rear crankshaft seal?

I havent fitted one to a crankshaft before, but fitted many to industrial gearboxes in the past. If installed correctly a speedi spleeve shouldnt cause to many issues with a lip seal - the sleeves themselves are quite thin. One important tip that I would give is to use something like loctite to "fill" the air gap under the sleeve and original shaft where the seal wear is. If you dont do this the speedi can overheat very quickly, wear through and destroy the seal. I've used metal putty on shafts with severe wear and put the speedi over that.

I have to my 4bd1t, you can get a wear sleeve and seal to suit for them. No leaks at all.

That's a good tip Shane, not something I've done when I've used them

Make sure you use a genuine seal......
