In this video I show how to replace the Idler Pulley and bearing on my 2012 Subaru Outback 3.6R. The process will be the same for 2010-2014 Subaru Outback and Subaru Legacy 3.6 engine models, check that the pulley part number is compatible with your Legacy or Outback 3.6.
Cost of the new Idler pulley with bearing at the time of the repair was roughly $35. Cost of just getting a high quality NSK or Timken (6203) replacement bearing would have been less than half, but I had the Pulley part on hand. I may go back and press a new bearing into the old pulley so I have it ready as a backup.
If you haven't changed your serpentine belt in a while, now is a good time to inspect it for signs of wear and cracking. Also a good time to inspect the Tensioner Pulley/bearing.
Part Used:
Continental Elite 50024 Accu-Drive Pulley amzn.to/33PdW5t
Alternate part option:
Subaru replacement Idler Pulley with bearing amzn.to/2Jo9br9
Tools used:
• 15" x 3/8" breaker bar amzn.to/2RnfJMs
• 14mm socket
Another option is to only replace the bearing:
Timken 6203-2RS Bearing amzn.to/2Ypokzj
Serpentine Belt (if needed)
ContiTech PK060640 amzn.to/2R0hNdC

Thank you! I just replaced mine on a 2011 outback 3.6r after I noticed a sound. It was very easy and the video helped. Mileage:~170000

I got a sound going from my 2010 3.6 outback and I believe this video may have just saved my day! Thanks man.

Check both the tensioner and the idler pulley bearings. Also a good time to replace the serpentine belt. I’ve got a couple more videos on my channel that are relevant. Good luck.

Thanks for the video. For future reference, it would be nice to know the mileage one the vehicle your working on. That way people would know when to look for these repairs on their own vehicle.Thanks

Good point, will try to include these details moving forward. Mileage at the time of this pulley replacement was ~ 95,000. I had already changed the serpentine belt and tensioner pulley bearing a few months earlier (I have videos posted for these as well).

I know the idler and tensioner pulleys are different but are you saying they do in fact use the same 6203 bearing?

@MattsGarageMiscDIY 4 жыл бұрын

Robert. On my 2012 Outback 3.6R they do both use a "6203" bearing. The pulleys are different diameter, but do use the same bearing. Hope that helps!

Matt, the pulley froze and tore the aluminum surface were the pulley sits… is this an easy fix?

Is it too hard to loose the belt and put it back on place?

@MattsGarageMiscDIY Жыл бұрын

It depends on how new the belt is. Generally a newer belt will be tighter as it hasn’t stretched over time.

Is the same bearing used for the 2013 2.5i Outback H4 engine?

@MattsGarageMiscDIY 3 жыл бұрын

Kyle, sorry for the late response, likely the same however I’m not sure. I was able to see the number on my old worn bearing (barely) after removing it with the pulley. Please do reply when you find out as it may help others. Good luck.

@@MattsGarageMiscDIY I ended up buying two idler pulleys from Reeves Import Motorcars on Amazon. They're OEM Subaru parts and work great. Part # is 23770AA07A.

@@kyleb0711 can you tell looking at the new part if the bearing is a 6203?

@@MattsGarageMiscDIY It's the same as the bearing on the original pulley: NSK B17-102DG4. I couldn't find that bearing number online and didn't want to risk buying the wrong bearing, which is why I ended up buying the whole pulley.

How did you just “slide the belt on”?

@MattsGarageMiscDIY Жыл бұрын

Joshua, first make sure you are routing the belt correctly around all pulleys, lastly use a ratchet to remove tension at the tensioner pulley, this should give you just enough slack to slide the belt over the idler pulley, but it will take a little coordination. With a brand new belt it’s a little more difficult generally because the belt will not have stretched at all. This is a good time to inspect your belt for any cracks and replace while you are at it. Good luck.

@@MattsGarageMiscDIY thanks, got it after I got a different brand belt. Not sure why the other one just refused to go on.
