While we are sleeving a NST Crank Pulley, this will work on a stock pulley.
Over time, a crank lip seal will wear a groove in the shaft of a crank pulley. It may happen a little quicker on aluminum over steel.
SpaceMonkey was the guinea pig for this mod. We did his truck today. Unfortunately my camera crapped out today. I do have some pics, I am missing some of the install pics. I have filled in with some sketches.
I will be doing this mod to my truck in a few weeks, so I will follow up with a few more pics.
For the record, I have about 10K miles on my NST pulley, without any problems.
This is a stock pulley with about 10K miles. No groove, but you can see a wear pattern starting.
This is a stock Toyota crankseal, it is spring loaded.
This is a SKF Speedi Sleeve. You need a #99165.
This is a very thin sleeve that fits tightly to the pulley shaft. It is hammered on with an included special tool.
This is a pic, showing the factory seal over the sleeve.
This is where I lost my pics. Once this sleeve is installed, it is about 1/16" too long. The Crank pulley on this engine butts up to the crank timing chain pulley. So you can not have this sleeve longer than the pulley. You have to trim the sleeve. Since the sleeve is so thin, you have to do it after the sleeve is installed.
We did this with a dremel. We used a cone type grinding stone. This was relatively easily.
Notice the angle of the dremel tool. We are grinding the sleeve, without gouging the pulley.
After grinding the sleeve back, we took an emery cloth to smooth out any burrs on the edge.
I would suggest a little grease or assembly lube over the sleeve, before installing.
We will let SpaceMonkey chime in from time to time, to see if he has any problems.
