Default serpentine belt replacement '01 OB LLBean

I am trying to replace the serpentine belt on my 2001 Outback. I was able to move the tensioner to reinstall the belt but the tensioner will not go back in place and tighten the belt. Any thoughts?

Haven't messed with mine yet, but I'll chip in that it may be worthwhile to replace the pulley bearings.

You can

a) get the assemblies from subaru (one idler one tensioner)

b) get 2 idler pulley assemblies from subaru and pull the pulley off one and put it onto your tensioner (have heard you can do this)

c) get 2 bearings from napa etc. and replace just thebearings.


The idler/tensioner bearings tend to go up around 120-150kmiles.

In the manual it looks pretty simple. Turn the tensioner pulley bolt clockwise to release tension, and I assume it just springs back when you let it go?

Is this how you moved the tensioner? And did you check the indicator marks to see if it was still working?

I'm glad you posted btw. Just about to order the parts for my own belt & pulleys. My plan was to order just one pulley, replace whichever one is stickier when I replace the belt, and then press a new bearing in the removed pulley to use now or later. But if your tensioner is shot, I might order a new tensioner instead.

Keep us posted. I'm especially interested if the tensioner pulley and idler pulley are in fact identical. I'd hate to disassemble my tensioner and find out that the pulleys are slightly different.

Both pulleys are the same.

IIRC the bearing you can get from Napa is the 6203-2RSJ bearing.

I used a 24mm socket, a long bolt, a bunch of washers (get larger ones so you press both the inner an the outer races) to press in/out the bearings. Basically with the 2 pulleys out, you can use the back of one pulley to pull out the bearing of the other....

Thanks kmltick! Hey...is there anything tricky about removing/replacing the tensioner pulley? Do I have to hold a spring in place? Or is it a simple unbolt/bolt operation?

It's a simple bolt / unbolt.

I'd say, the only trick is there's a nut that's behind the tensioner (for pulley), just make sure that doesn't fall into no mans land.

You'll be surprised how easy it really is...

Thanks again, kmltick! I've ordered the parts. Will endeavor to post pictures when I do this work in the next month or so.

roadhog...any update on your tensioner problem? Did it snap back eventually, or is it broken?

Interesting timing, my belt broke today. It also looks like one of the pulleys was bent in the process, looking from the front the one on the right.

What are the part numbers of these two items? Should I snap a pic to make sure?

Why always in the winter, it's cold in my garage.

Yes!

Take a good look at the mounting bracket too. If the idler pulley looks skewed, the bracket might be damaged. I think it's part 23950AA011.
