Grease the crank?

[MOSHO92]

When putting back on the crank timing sprocket and the crank pulley should i use some anti-sieze **** to slide it on or might that cause slippage (crank cancer).
Also how much does a new crank pulley cost? (i put a good chip in mine)

Yes, a little grease to prevent corrosion would be a good thing. I used some redline assembly **** that I had lying around.

Just make sure that you torque that damper bolt down to the required 113-126 lb-ft.

Thanks for pointing that out! thumbs_u I always take for granted that the nuts and bolts will be torqued properly because I've got a very nice Microtork (20-250 in-lbs) and a Digitork (25-250 ft-lbs) torque wrench. Folks, use your torque wrenches if you got them and if you don't then get some!! And if you don't know the torque values for a specific job then just ask!

MOSHO92,

Let us end this old wives tale about crankshaft sprocket or pulley "slippage". Planely and simply it is a crock of bovine excrement.

The sprocket and pulley are keyed to fit tightly over the woodruf key on the crank. It is a friction fit, and PHYSICALLY LOCKED IN
PLACE(PERIOD). There is no lateral movement possible.

The sprocket and pulley will only move front to back or back to front, as long as everything is in good shape.

So, putting a little grease on the crankshaft and on the inner surface of the sprocket and the pulley will protect the surfaces from moisture and corrosion. If they will move laterally, left or right, then they do not fit tight enough and should be replaced anyway.

I have been greasing the end of cranks, woodruf keys and pulley/harmonic balancers for 40 years and have never had one fail. Not on the street, nor on the strip, nor on a road course, nor during a gymcana run(sp).

The grease will prevent "crank cancer". Once you have crank cancer, the only cure is major surgery.
The keyway has to be remachined in to good metal, and the woodruff key replaced to fit the new keyway. Then the sprocket and pulley need to be machined to fit the new woodruff key.

To prevent cancer from reoccuring apply a thin coating of grease. Or you could just buy a new crank, sprocket, and pulley! Then move to the southwest where there is little or no rust. rangerj

All Right, thanks for the info. I hope i ward off the cancer for another 100,000 miles or so. I will be using some loctite (sleve retaining formula...real strong stuff) rather than grease, but i do believe it should do the same thing.
