Timing sprocket?

Featured Replies

If I use this sprocket, is it going to screw up the belt?

Idiot before me tightened the hell out of it, my channel locks slipped ????????????.

Yeah I wouldn't chance it. That's just asking for trouble. Not a question of IF it will cause problems, but a question of how long will it take to shred the belt?

No definitely would not use it. Any little knicks or burrs will wear the timing belt. The sprockets and idlers should all be nice and smooth.

That's what I was afraid of, or thinking was the casefreaking idiot!

An idea for next time: wrap the old belt around the sprocket, and then apply your channel locks.

you could reuse it assuming it's not cracked.  sand/grind the edges of all the broken edges all down smooth, making gradual transitions and they'll do exactly what the teeth currently do - gradually engage with no impact on the belt.

 

but it is generally easy enough to get another one - they're easily found bratman probably has them, i probably have them...

I didn't even notice the manual lol, next time pull the valve covers. You can get a large wrench on the cam to hold it in place to remove the bolt more easily.

 

I don't think I have any extras at the momente, but I would have to look to be sure. But they are really common, I've seen a set or two posted on legacycentral and rs25 in the last couple weeks.

The nylon sprockets are brittle. Any damage or knicks in the surface could create a weak point and the sprocket may break. Better off to replace it. Not something you want to take a chance with on an interference engine.

Yeah, live and learn figured this one out for the drivers side.

From the pictures from the manual in the background I'm going to guess dohc 2.5

Almost, it's SOHC, couldn't find a manual for the Forester so I was using the one for the 1st Gen Outbacks, which has references for the SOHC.

 

Did score a PDF for the 98-02 Forester though, I just had the Haynes handy for the timing thing.

Contact AdventureSubaru, he's got parts from two dohc's laying around.

Are cam sprockets the same from the SOHC to the DOHC?

Dang, I'm not sure if they're the same. I know the dohc ones have a lip on the edge of the top PS and the bottom DS. The top DS sprocket looks like yours, if they're the same diameter I'm sure it would work. The bottom PS one mounts differently (not a recessed bolt like the others) so probably wouldn't work. It may, but you would also probably need the corresponding bolt (probably longer)

 

On another note, I'd still hit up Matt(AdventureSubaru), he may have SOHC ones too.

They are different. but I actually have sohc cam gears sitting around.

Awesome, do you have a PS one?

SOOOOOOOOO    worth the money......I have one of these for each type of sprocket  (SOHC, older DOHC, newer DOHC,  ACVS)

Probably not going to be doing enough of these to justify buying one or 2 of these too.

 

Thanks for the link though.

That, or you could make one. I've been contemplating fabbing up one of these doohickeys myself. I've got enough flat stock and grade 8 bolts laying around to make something work.

Only one is needed for the SOHC motor. 

 

2006+ turbos require 2 different tools......one for ACVS (intakes) and one for exhaust........(tip* the 12 point one for these newer exhaust cams will work on the six points of the older 2.5 DOHC)
