It's time IMO to change the factory belts on my Accord, in doing so I figure why not add underdrive pulleys too.

My questions are?
A special tool is required to hold the OE power steering pulley to remove the pulley nut. Did you guys purchase this tool or make one on your own? My helm's lists the Honda part no. for the tool. Nothing special by the picture.

Second, the Alternator pulley is held on by a 22mm nut and the alternator shaft has a 10mm head on the end. Helm shows using 2 box wrenches to remove the 22mm nut. I know from others this 22mm nut can be a B**** to remove. Helm lists using an impact wrench if needed.

I assume you need to get the Alternator out of the car for this, no biggy-- 3 bolts and it comes right out the top, thank you Honda. But how do you use an impact on these bolts?

Do you hold the 22mm lock nut in the box wrench and use the impact gun on the 10mm Alternator shaft? They make a 10mm inpact socket? Sounds to me like a good way to A. hurt yourself with a spining box wrench, and 2. a good way to make alternator current that could discharge in a rare case I sappose.

Do you just place the impact on the 22mm nut and hope it comes loose with out spinning the shaft much? I don't own an impact but a buddy of mine does so he offered his services for the weekend when I plan the job a few weeks down the road. Else I assume an impact works a bit like a hammer drill?

Any help would be appreciated, I assume this job is about the same on any 4cyl Honda Accord.

I plan to take pics and post a write up on the job once I do the job, if I get the job done

 

The ultimate question, "Why"? Is there something wrong with the pullys you have on there? The pullys dont have bearings themselves or anything I see no need unless they are chipped and causing damage to your belts.

 

Well I dunno if it's really smart to mess with your pulleys...I've heard many stories of aftermarket pulleys chewing up alternators. Since your car isn't modified much, they really won't make a difference anyway.

I changed my serpentine at 160k and my power steering is fine by all accounts. Why bother? It's a lot of work, especially the PS pulley.

 

do it, get UR pulleys and let me know how they do...i'm going to be ordering a set soon myself

 

they are a waste of money, it could be better spent on a more worth while mod.

 

Killing the alternator doesn't make sense if you think about. It would just spin slower, it's output is what it is, it's nothing more then brushes making current.

They could drain the battery at low rpm but it shouldn't kill the alternator, I have a volt meter and plan to also install a new deep cycle battery it should be fine.

In any case anyone have an answer to the questions I asked?
In addition, do the 6th gens use left hand threads for the pulleys or are they normal threads?

 

p\s pump pulley reverse threads just hold the pulley with a rag in your hand, accord v6 alt. never seen one of those go out haha only replaced about 10 or 12 rest of the pulleys all come off normaly

 

So the P/s pump pulley on the Accord 4cyl is reverse thread?

And the Alt. pulley 4cyl is not?

Just seams weird since they both set on the same side of the engine?

Thanks,

 

Yes, the alternator pulley is normally threaded and the power steering pulley is reverse threaded on all Honda motors.

I wouldn't waste your time or money on the pulleys. The gain will be minimal for the amount of downsides they have.

 

Has anyone ever killed an Accord 4cyl Alt. with the AEM pulleys? That's the only downside I see? My battery is almost 6yrs. old, it needs replaced anyhow. I was going to do a deep cycle unit for that anyway since I don't drive the car a lot. My radio is stock. The 6cyl. has alt. issues unrelated to the pulleys if you ask me.

The pulleys just make the alt spin slower, it's output is RPM dependant anyhow to a limit rpm. How could slightly slowing the units spin kill it, your car runs off the battery not the alt. current? At most you charge the battery slower, if you are running a healthy deep cycle this shouldn't be an issue. Now if you had a sick battery and a weak Alt. current then I could see the alt. directly powering the car and then you could run into a current shortage issue putting strain on the alt.

Aside from the suspected Alt. issue what is the downside? Hey I'm only expecting minimal gains, not even really seat of the paints gains really. But I'm going to change the belts, I figure this sounds like a fun project to do at the same time. The pulley price isn't huge at all IMO. Clearly I can't see how the gains are any less $/hp then an intake as bolt-ons go. I've spent way more on the suspension, this seams like chump change Ekking even 1-3hp out of the engine would be a gain for this motor IMO.
