ORO York OBA Bracket Install

My old York OBA bracket required frequent adjustment to keep the belt squealing and chirping under control. Each time I needed to remove the air box and struggle with the bolts under the bracket. A few months ago, I bought ORO's bracket kit. I finally got it installed yesterday.

The ORO bracket is a very different design from the Kilby. Both are very well made and fit perfectly. The ORO is either painted or powder coated. Mine had several paint voids. The Kilby bracket coating (zinc?) will probably last much better over the long run. The ORO bracket puts the alternator in about the same location as the Kilby. Installation of the alternator is more difficult than the Kilby, but keep in mind there is a lot going on in front of the bracket. The bracket has a recessed tab to attach the top of the alternator. It can take a few shots to get the bolt in through a hole in the front of the bracket. Removing the bolt is very difficult. The bottom bolt can also take a little work. After getting it in, I found that it is best to do it from under the Jeep. In addition to the stock tensioner, ORO uses another idler pulley. It is best to install it from underneath too.

I had to make several trips to get bolts. I probably still had the stock bolts, but they are buried in a storage room I am renting while I rebuild/remodel my garage. If you are installing from stock condition, you will not have to make those trips.

Initial results are very good. No noise while the alternator was under load, AC and OBA on.

Re: ORO York OBA Bracket

Let me know how you like the ORO bracket after some use. I can't stand the squealing and chirping the Kilby bracket causes.

If we can ever get a Houston get together scheduled, I'd love to look at your ORO bracket.

Re: ORO York OBA Bracket

Ive had the ORO bracket installed for about 2 months and have yet to hear and squealing or chirping, even on these cold mornings.

Got pics?

I have the Kilby bracket and the squeals every time I drive it, usually just after startup though. I'm considering removing it and going to an electric compressor, once my Jeep gets the new motor installed.

My Kilby OBA bracket on my TJ cracked in 2 different places, but luckily it was caught and fixed before the compressor fell off the motor.

A Houston M&G is very overdue. We took it on a 150 mile trip last Sunday. It was nice and quiet, even on start up. Time will tell...

Jimmy, I plan on giving it to my dad. I have a bunch of fittings and hose left over. Maybe enough to do an install on the cheap.

Brad, glad you deleted your post.

Brad, BTW didnt mean you any offense with my doorstop comment was only playing around as i tend to use perfectly good parts to prop doors open at times.

Dont want anyone thinking i'm bashing a kilby product, my wallet just bashes me everytime i drool over kilby stuff.

MJM, any updated thoughts on the ORO bracket now that it has been on for a few months?

I will state that most of my squealing with the Kilby is gone. Only a brief second on a rare occasion.

I have been running the Kilby for 4 years now and the only time my belt has ever squealed is when its getting worn and needs replacement. Installed a new gatorback belt and never heard a thing out of it again. That was 2 years ago.

I have a noise under the hood, but I am afraid it might be the cam position sensor (it has been parked for about a month). I need to replace the one idler pulley I reused. I hope that is it.

I have an AEV Highline conversion and rainwater pours down the hood right on top of the engine accessories. I wonder if this might be related to the idlers going bad.

I've had the kilby bracket for a number of years on mine and have had no squeeling issues. I did have to get a new york I put on 2 weeks ago and it squeeled a tiny bit at first and it just needed a little adjustment on the york mounting. You really need to be sure you have the york mounted straight in line with belt path so when you use the studs to pull it tight you need to be sure that the belt is tight enough and you are completely even front to back on the york as you tighten it down. If you do it properly you should have no noises or issues at all.

the bearings are sealed so that shouldn't be it, but stranger things have happened.

I give up! I quit driving it for about a month because I needed to find the source of the noise. I had to move it this weekend so I could work on the garage. No noise, no problems.
