X64v Posted November 1, 2007 Share Posted November 1, 2007 As the title says, is this possible? I've got a factory 3 row pulley on the front of my '73 l24, and since I'm not using the last row, I figured I'd see if it came off. It appears to be bolted on, but removing the two bolts didn't free it up. Is it an interference fit, or do I need to remove the crank pulley bolt, or what?

I can't help ya except to perhaps suggest rust adhesion? Quote Link to comment Share on other sites More sharing options...
X64v Posted November 4, 2007 Author Share Posted November 4, 2007 It's certainly possible. I didn't want to pry on it too hard though, just in case I did need to unbolt the center bolt, or if it didn't come off at all. For what it's worth, the main and center pulleys spin straight and true, while this last row has always wobbled just a little, which would indicate to me that it is in fact removable.

TONY C Posted November 4, 2007 Share Posted November 4, 2007 when I built my edis setup I had to have the pully you are talking about machined off so I could attach the 36-1 wheel. I thought the same as you but it was not coming off without machining. was cheap tho. Quote Link to comment Share on other sites More sharing options...
Tony D Posted November 5, 2007 Share Posted November 5, 2007 I cut down my two-groove solid JDM pulley to one groove. No reason to think Nissan changed much over the years. Face it off and if the thing pops loose on the lathe, you are done earlier than you expected! Quote Link to comment Share on other sites More sharing options...
X64v Posted November 5, 2007 Author Share Posted November 5, 2007 Well if that's the case, both extra rows are coming off. Thanks guys for your responses. Quote Link to comment Share on other sites More sharing options...
Zmanco Posted November 5, 2007 Share Posted November 5, 2007 My L24's pulley had the third groove bolted on via 2 bolts in the front. I believe it was added by the dealer during the A/C install. The main bolt into the crank doesn't have any affect on the outside pulley. My guess is that it hasn't been off in more than 30 years and will need a little help to come off. Puller?

X64v Posted November 5, 2007 Author Share Posted November 5, 2007 Ah, there we go, exactly what I was hoping for. My z came with dealer installed a/c, and I was wondering why it would be bolted on if it didn't need to be. I'll work a little more at it, I didn't try too hard just in case it wasn't just bolted on. Thanks a bunch Quote Link to comment Share on other sites More sharing options...
Zmanco Posted November 5, 2007 Share Posted November 5, 2007 I just had a flashback and went out in the garage to check and I was mistaken above. The A/C pulley IS ATTACHED via the crank bolt. Sorry for the mistake, it has been a few years since I touched that engine. Edit: added picture Quote Link to comment Share on other sites More sharing options...
X64v Posted November 5, 2007 Author Share Posted November 5, 2007 Quite alright, I was just about to post my conformation of your correction. After the thing wouldn't budge, I decided to pull the whole pulley/damper assy. off to use a puller on, and once I cracked the main bolt loose, voila, the third row was loose.
