February 13, 201412 yr Hi all, Am doing my first ej25 head gaskets timing belt waterpump etc on an 03 Outback. I am installing the new timing belt from Subaru and noticed a tooth on the belt that has some metal belting-like material showing on the sides, the old belt seems to have 2 such teeth but is in otherwise good shape for a belt with 150k on it. I am wondering if this metal showing on a brand new belt should warrant a return of the new belt or is just part of the manufacturing of the belt and is ok. Attached is a photo of the tooth. Thanks.
February 13, 201412 yr stop in and compare it to other belts on the shelf? is it around the area where the two ends of the belt come together?
February 13, 201412 yr Author The dealership is quite a ways away so I was hoping someone on here who had done a lot of these could tell me if this was something normal or not. Looks like its away from the area the outside of the belt joins but this could be the area that the inside rubber joins?
February 13, 201412 yr ironically i have a new aftermarket EJ25 SOHC belt sitting next to me in the office. it doesn't have a mark like that. it does have one "seam" on the inside tooth where the two sides come together and are attached. This one appears to have some kind of material woven across the belt tooth in a spiraling pattern, yours might have that, but hard to tell from the picture. It is 7 teeth away from one of the cam sprocket marks - I think the drivers side one.
February 13, 201412 yr Author I think this is the same thing you are talking about. Mine is about 15 teeth from the sprocket mark. But I am sure that changes batch to batch. It looks like some kind of spiral weave and looks almost like dental floss or something. I bet they both have the same markings. Thanks very much for your help.
February 14, 201412 yr That's where they join the layers of the belting together during manufacturing. Ive seen that on many a timing belt. Not a big deal. If you look close at any kind of rubber belt, even a regular serpentine belt, you will see a funny spot where the layers join. That's basically the start of the first layer of rubber where they wrapped it around the drum they use to form the belt.

Thanks very much for your help. your first descripion of metal and the pic didn't look to me like what i was seeing, but sounds now like that's what it is.
