Crankshaft pulley

[Vesuvio]

Converting my manual to a power steering. Got all the parts, except the double grove crankshaft pulley; any idea where I can get one? Thanks

6 cyl engine

Is the double grove pulley supposed to be one piece, or something like in this picture?

The double-groove pulley on my AMC 258 i6 / 4.2l has a built-in harmonic balancer, it's not separate like on the bigger motors.

Will your power steering have a V-belt or serpentine?

V-pulley to add to the balancer and pulley assembly:

And a double pulley for the power steering pump:

Just remember the AMC 258 i6 / 4.2l and AMC 232 i6 both came in so any other cars. I have an online 6 in my jeep and the gremlin parts have come in handy.

Morris4x4 closed. Anybody else know where I can find a double groove crankshaft pulley with the 3 bolt pattern on an AMC 258ci?

Mister Gasket part # 4977 maybe?

That is a water pump pulley. I have only been able to find single groove crank pulleys. I'm leaning towards ordering a used one from one of the many used Jeep suppliers...

 

[MemphisPapa]

Is there a list of such used part dealers? I've searched eBay and the like with no luck. I found a bolt-on option at BJ's Full Sized Jeep parts. I'm not sure how that will turn out.

I swapped out the water pump pulley today and still looking for the crank pulley. I had a moment today looking at what I have and briefly wondered if I could skip the crank pulley upgrade and buy a shorter belt from the double water pump pulley to the power steering pump, but I don't think there is enough travel in the PS bracket. Then I remembered the travel on the alternator is very good. Has anybody tried this without the double pulley on the crankshaft and used only the water pump double pulley?

First, have you tried CVF or March for a pulley. I think they’ll be able to help too with the added groove you’re looking for.

Second, I don’t quite follow your question about belt routing for the ps pump. Are you wondering if it can run solely off the water pump pulley?

The CVF bolt-on solution is described for 1980 - 1990. Mine is a '76 so I'm not confident. I had not heard of March Performance, but those are also for the 4 hole pattern. Mine is similar to the CVF bolt-on 3 hole solution and currently lost in the mail.

And, yeah. I'm asking if I could try running the alternator with a short belt only from the double water pump pulley and run a single groove on the crankshaft to the double water pump and the power steering pump.
