Default Awesome post!

Hey guys, Just found this post and the vise grip idea worked great! I used another vise grip to lock the belt top and bottom together near the cam sprocket. The locked teeth keep the sprocket from turning and the crank acted as an anchor. Only needed one breaker bar (on the sprocket). Hope this helps!

Bad Idea, I just broke the passenger side exhaust (plastic) cam gear doing this.

No substitute for the right tool (unless you are very lucky).

Don't listen to him.

He's a plant from the Subaru Tool Manufacturer.

Everyone keep using their old timing belts.

Nothing to see here.

How on earth did you break the cam gear?!!! I've never seen that happen. Are you sure you were turning the correct direction?

If you clamp the belt this way it doesn't try to turn the crank when you put torque on it:



Koken 10mm hardened allen and a 30" breaker bar made short work of them.

Here's my setup for breaking mine loose. I jst left the belt on with tensioner. Didn't skip any teeth (uh, that would be bad!), but I started to see some belt flex on the driver's side intake (the one with the most valve spring load when the engine is timed). Hope I wasn't taking too big a risk...

That method is bad. Waaay too easy to skip teeth and bend a few valves.

I'm sure you can get away with it a bunch of times but it's that one time that'll cost you.

Yeah, you're going to pull the belt anyway, much safer with all the valves closed and pistons at half mast.

Some perspective: The two Subaru techs who mentioned the hammer "shock treatment" have most likely adopted this technique because they do this pretty regularly, and their experience is that it helps.

I don't think they are suggesting to whale on it like a gorilla, but I worked for several years as a tech and I often used this method, when needed. The idea is that the bolt was torqued pretty good and has been sitting for some time. If you just try and gradually apply torque in the "loosen" direction, you often don't get anywhere. If you can put some initial 'shock energy' into the bolt, this will often let you then overcome that initial 'set'. This is why impact tools work.

I might also suggest that instead of tapping on the hex bit straight into the socket of the bolt, instead get a flat-end round punch, and tap the bolt at an angle at a few different positions around the bolt. Using this method I often found that stubborn bolts came loose without too much effort.

"Subaru tech" does not equal sensible mechanic. I've spent my fair share of time behind the scenes at dealerships and have seen the good and the bad. I'd give a flat rate tech credit for finding the fastest way around a job- but not the most sensible.

^^^ Agreed. I guess I was just trying to point out that what might sound like a brutal approach can, in the right hands, solve an otherwise difficult problem. The mechanic still has to be using understanding and experience.

I found this thread after I had fought with this for quite awhile..my upper gear bolts came out fine, but the lower ones were stuck....some decent ideas here, but I'm *really* not a fan of the vise grip/death torque approach. This puts too much stress on components never designed to take that much torque.

After trying the impact gun (IR TIMax - no joke gun), the "medium" death torque approach, and some heating/etc I was able to drill the bolts out in about 10 min (each) with a 7/16" Dewalt Titanium coated drill bit. So for $16 (new drill bit $12, bolts $2/each) I had the bolts out in 20 min with no damage to the motor at all. I highly suggest taking this route and using lots of oil/cutting fluid to keep the bit from dying. The part number for the lower cam sprocket bolt is 13199AA010 in case you want to get it online...

the double wrap approach I think is ok. You'd be surprised at the amount of torque going through those cams. I wouldnt do it without first moving the pistons to neutral and letting the cams come to rest. You have to let them come to rest anyways. Unless your straight on the cams gear you still apply that kinda stress.. not that much difference.

A lot of good ideas here. Had to use more than one method to get all the cam bolts out of an MY02 EJ20.

Thanks guys.

the belt thing didnt work at all for me. Used the tool (aka ST tools from subaru) and a 1000lb impact took five minutes taking all the gears off.

Good job...

This is the thread for people without the "tool and 1000lb impact".

But thanks for the update.

you can also drill half inch in with a 5/16 drill bits and it will come off real easy
