Just in the nick of time! I received my new OPDA and installed it today. Lots of wear on the old one and very difficult to rotate by hand. New gasket wasn't with the new unit so I re-used the old one. Wasn't too difficult, had to turn the oil pump several times to get things to line up. Biggest PITA was the 1/2 inch hold down bolt. No luck finding a 6 point 1/2 inch wrench, used a ratcheting box end and it worked fine.

Thanks to all you super techs for this thread, saved my bacon. Dealer wanted $400.00 plus to do this. 25 minutes and I was done. My engine has less than 40K miles.

One thing I noticed was that there was chalk/grease crayon around the TDC mark on the pulley, perhaps evidence of OPDA replacement under previous ownership.

Hopefully I'll manage to get the notorious clamp bolt off tonight, should I buy a long-handled 1/2" wrench for this? Just so I can get more torque.

I bought my jeep used and the guy doesn't know if he had it fixed. Is there a simple way to check if the repair has been completed? Thanks! Tom

If the dealership made the repair it will be in their database.

The seller doesn't think they completed the repair. He beleives they had to order the parts. The dealership went out of business and on the last day they were open they put in the computer repair complete per my local dealer. Now what?

Pull it and look at it. If it's hard to turn and the gear's worn bite the bullet and replace it.

Follow the youtube video on the first page. You'll need a T25 torx (I think I said T20 in the video), a 1/2-6point wrench, and potentially a long flat head screw driver if the oil pump slot doesn't cooperate.

I'm having a hard time understanding all the TDC stuff. It's really not necessary to move the motor. Just follow the directions on that youtube video.

With a manual tranny, you can get the TDC hole to line up easily by putting it in 5th or 6th gear and rolling the jeep forward until you see the hole in the one wheel like up with the hole in the cup.

The video demonstrates how to put in the same one that was just removed. I'm installing a new one.
It was super easy to turn the engine once I got the rear wheel up anyways. The only annoying thing was running back and forth from the wheel to the engine since I was doing this alone :P

Rolling the car forward is not an option for me since I dont have much space to work on this. There's maybe 4 feet left once the jeep is in the garage, and it's too cold and rainy outside

I replaced mine today with a Fog'd unit that Willy did for me. My old one was actually in great shape and spun as easily as the new one. The gear shows very little wear for having ~79K miles IMO.


I sure I knew why some have issues early, and others (like me) never do...

So I pulled my OPDA (REV-B) from my 2005 TJ with 165,000kms on it, I have two extremes to share:

The bad:
MAJOR Gear wear:



The good:
Spun freely.. and get this. EVIDENCE OF OIL!!!


But ugh... I REAAAAALY don't want to replace the cam shaft, lifters, etc....
