Install of Speedi sleeve to repair crank

I have a 2.4 crank that had a groove cut in it from the main seal riding on the crank.



I purchased a Speedi Sleeve part number 99254 for the 65mm journal. I got my from my local NAPA store for just over $50, they did have to order it.

They make another more durable sleeve for more money. Mine is a racing engine so it will never live that long.

To install I placed the sleeve over the end of the crankshaft.




Then placed the installation tool, provided with the sleeve, over the sleeve and placed the crank in a vertical position and hit the intall tool with a hammer. Not a big hammer and I hit it on a rotational pattern to keep the sleeve moving onto the crank straight.



Some things to notice at this stage. First the flange on the sleeve can be removed at this point and the sleeve driven down further. I measured the groove used to seperate the flange and found it to be out of my sealing area so I chose not to remove the flange.

Another thing to notice is the sleeve is too long for the Porsche crankshaft. We also have to keep in mind the flywheel slips over the OD of this journal. So it must be trimmed.





I chose to use a lathe and a carbide bit to trim the excess material
Had I been a better machinist, I would have measured the thickness of the Speedi sleeve and removed just that amount of material. I also would have known how far down the crank I should make the cut. I did not have a flywheel handy so I guessed. If anyone has a flywheel laying about could you please give me the depth this needs to be cut?

I would bet a large pipe cutter would also do this task.



Here is the finished product. You can see the groove I cut into the crank. I don't believe this will be a problem and I now have plenty of good sealing surface.

A seller of Speedi sleeves told me you can mount the sleeve on a wood dowel in order to cut it to length. You would need to do something like this if installing it on a crank already in the engine.

If you remove the flange, how do you drive the sleeve farther down? Is there enough of a lip left? the flange only needs to be so wide to get things going? This has puzzled me.

The flywheel lip depth is about 4mm: from an aluminum aftermarket flywheel and a slightly buggered steel aftermarket wheel. 4.22 on a really buggered (as in what happens when the bolts loosen) stock one. I'd all a bit more to be safe.

Walt,

If you remove the flange there is no lip left. I thought you would have to bang on the material that overhanged the crank. I did this testing the column strength of the sleeve and to be sure I had my sleeve seated. It bent pretty easy. I am not sure you could press it down further. Perhaps if you used a piece of wood or aluminum to help spread the load. Or put it in a press.

Thanks for the measurement, I will check mine to be sure I have clearance.

S t o d d a r d has this for 911. I know this site doesn't like advertising other companies, but I don't think Pelican sells these.
