Icon6 '91 EF - pulley coming off the crank

Hey guys,
here's what I have:

1991 EF civic hatch with a '93 Integra B18A1 and cable tranny installed. Solid mounts and motor runs nice. Have an issue though...

Just recently, because the car was lowered when I bought it, noticed a chirping/grinding sound coming from under the hood on the drivers side near my left foot. Looked when I changed the oil yesterday and looks like the pulley coming off the crank is grinding away at the strut rod (I think that's the right part name) any ideas on how to fix it? I know putting a new rod in is part of it, but I don't want to put a new one in and still have the same problem. Car has no A/C, no power steering, so only belt running off the crank pulley is the alternator. Please fell free to send me intel on how I might go about fixing this. This is my first post and I'm kinda new to the Tuner scene, so please, if you can, be gentle!

Sounds like the engine mounts have the motor sitting to low in the engine bay, causing the crank pully to hit the radius rod. Get new mounts or a ctr crank pulley

Get a CTR crank pulley. I had the same issue with my current EF. I had an older EF with a b swap and used hasport mounts and had no issues. I used some no-name mounts with my current b20 swapped EF and my crank pulley was literally grinding away at my radius rod due to it sitting the motor lower in the car. Swapped out the stock crank pulley with a used CTR pulley I got off here and problem solved.

It was only when it bottoms out, but here recently it's almost all the time. I've even noticed in the past week that now my alternator pulley had started to rub/chirp against the inner portion of the fender wheel, same side of the engine bay.

Not sure on the tech term, I've been told it's a strut rod by one guy, a radius rod by another and one good ole boy I work with says it's not a problem, just what "old Hondas sounds like from time to time". With her riding a good 2-3 inches below stock height already, (lowering coils/springs were installed by previous owner) a suspension lift, even by an inch may help tremendously.

Oh Creator, I'm no where near "crafty" enough for that build, but danged good workmanship on that whole page. I wish I had learned to weld when I was in the ARMY, it'd save me a ton of work.

Did you have any issue with balance or under/over drive on the alternator with the Ctr pulley?

Looking to raise suspension and also add adjustable A arms up front to help address camber wear on inside of the tires as well. Any thought/ideas on "solid/dependable" camber kits that fit for less than $400 for parts?

A camber kit will not rid your car of the excessive tire wear. When you lower these cars two things happen, yes you get negative camber, but you also get toe out. The toe is the real culprit of your tire issue. If you plan on raising the car up some you might want to wait to get an alignment, but in the end what you really need is an alignment. Don't get me wrong a camber kit will help with traction, but it is not the root of this issue.

Finally if your looking to dial in some camber I would have originally sugested Hard Race, but it seems they may have discontinued the set they used to make for EFs. Next best would be Skunk2.

Honda gurus need some help. I think the issue I'm now having with my EF, after I've had the alignment done, is the motor mounts. They're sold aluminum, not sure who makes this set, but I'm having issues with crank pulley wear. Haven't located a ctr pulley yet, but these pics seem to show a bad bushing or connector to the motor. Any one know what these should look like? I'm still new at this and these are my best photos si far, just need some guidance. Thanks!

Are you describing your "bad bushing or connector to the motor" as something you think goes between the motor mount and the engine?


All I see in your pics are;
aluminum mount that bolts to the chassis
the other half of the mount that bolts to the engine (stock OEM part)
timing belt cover
rubber timing belt trim (#8 & 9 in the image below).

CTR pulley is $69 on Hmotors. Located. Those pics also show almost nothing. I think you should just go with the CTR pulley though.

Sorry 4dref. Hadn't had a chance to remove the timing belt cover yet. It looks like the mount might have dropped down and isn't exactly lining up like it was before. When I get it off I'll take better pictures. Bad thing is, the crank pulley it's nearly constantly chirping/grinding on the radius rod. I'm afraid it'll do too much damage before I can replace the rod, any thoughts or ideas?

No worries! It's a website. HondaTech generally agrees that they are the best. The only thing I can tell you is their customer service is GREAT even if you don't buy anything.

I believe that is it.
