another question about the crank pulley

[e_racer1999]

didn't want to hijack stephen's thread, but i am having an issue with removing the crankshaft pulley

the bolts that came with the pepboys puller i bought are the wrong size, and i was wondering if anyone had any advice on where to find the right puller or what size bolts to use...

anyone?

I use they type of puller with three arms that clamp on the back of the pulley and a center stud that you turn with a wrench or socket against the crank snout. I bought mine at Harbor Freight. They're fairly inexpensive.

Like these:

so a 3-leg puller will work? i was reading in an older thread (ca. 2004) that these can damage the pulley.

if that is not the case, then YAY!

[sblake01]

I've used them with no problems.

excellent. off to pepboys after work. my car *should* be running this weekend

[ezzzzzzz]

If the hub is seized to crank nose or the rubber is in poor condition you can dislodge the outer ring from the hub using a three arm puller. The rubber literally shears or separates from the inner hub and outer ring. That renders a crank pulley useless. It would be better to acquire the proper bolts to use with a hub puller to ensure it comes off straight and causes no unnecessary damage.

thanks for that recommendation....

on that note, i know that the bolts are M10, but does anyone know the thread pitch?

While I don't know the pitch off the top of my head I can offer a suggestion for the future. I went to my local hardware store and simply bought one each of metric nuts and bolts in the common sizes used by Datsun. You can store each pair in a labeled bag and can use them to verify sizes whenever you need to buy new fasteners.
