Here's one more technique for y'all. Take a tube of plumbers epoxy, the play-doh type stuff that's grey in the middle and green around the outside. Roll it in your hands to activate it, then form it into a triangle about 1" wide. While it's still malleable, feed it in between the intake and exhaust gears and roll the gears in opposite directions to pull the epoxy in towards the middle of the motor. This will form your triangle into a wedge with teeth mirroring the cam gear profile. Once you've got it formed nicely, roll the gears the opposite way to remove the wedge. Let it fully cure/harden. It helps to put saran wrap or a little oil on the gear so the epoxy doesn't stick to it. Once your wedge is hardened, put it back in and now the gears will lock against each other and you can crack on the bolts. This has worked great for me. Cost about $2.

I also found out that the Snap-on 10mm 1/2" drive hex socket was very strong and would not break like craftsman and several other that I broke. It lists of $20 but its worth it because you break several $10 sockets and never get one bolt loose.
I had no idea how much harder there were to remove than the 2.2L Phase 1 engines I have worked on in the past. Impact gun won't touch them.

I used this method but the belt kept slipping so I used two vise grips, wrapped the belt all the way around the crank pulley and clamped, then pulled the belt tight on the side it would be pulling and wrapped all the way around the cam pulley and clamped. (I actually used third vise grip on this side after the first one just to get it a little tighter... between the second vise grip and the cam pulley)

It took a 2' breaker bar w a jack handle on the end (over a 3' lever) and I almost lifted my 215lb keester off the floor before the exhaust ones broke free. I didn't dare use my two part craftsman allen socket for this and no snapon store nearby so I bought a set of impact allen sockets from Harbor Freight (They dont' sell them individual) It worked great.

Holy Guacomole!!! These bolts were a nightmare but once I figured this all out they came off with a snap.

Company 23 makes some awesome tools for this. We couldn't get those pesky gears off until we got one person holding down the gear with the gear tool and another person with half inch ratchet 2 foot long breaker bar on the other side. But that's how we did it on my car, also helps for holding cams in place while putting it back together and getting timing right.

Default STI Cam Sprocket/Gear Removal??

Best Allen key and heat always but I would stay away from impact tools or you will have to do what I did here. Which is actually really easy if you have a welder.

I agree that using an impact gun is not a good idea and will be futile anyway. Use of an impact allen socket may be necessary with a breaker bar because I have had the two piece regualr allen sockets break.

I appreciate your resourcefulness and am not looking to criticize your work or start a debate. I just wantt o caution other readers that IMHO, I would not advise using heat as the exhaust cam pulleys are plastic... unless you plan on replacing them.

I tried an impact gun, big breakers, and the Company 23 tools, and the allens just rounded. Drilling with a good bit and cutting oil worked like a charm. I definitely recommend this method.

Smile Subaru Camshaft Sprocket Removal

Hi Guys and Gals. I work on Subarus a lot. I am a ASE Master. I made a video that solves removing these Camshaft bolts very easily with no failures to date for me. Its simple, its fast and no special tools are needed. The video is only a couple minutes long. I hope it helps someone else out.Here is the link.

I basically did the same thing on a stand... I could not get the bolt out and had to drill. The leverage I had was provided by sticking a gun barrel of an F-16 on my ratchet. I broke bits and ratchets, and then stripped the Allen head.

In the end, drilling wasted less time for me.

Default cam bolt removal watch this first!

Watch this video before you attempt any other method on the cam bolts. This should solve all problems. No special tools needed. ~shaun :banana

Thanks for the video... but did you really need to bump 5 other decade-old threads?

Interesting way to do it, thanks for the video. I would think you could use this to torque the bolts up again when installing the cam gears.

Note, if clamping a timing belt like that, I would likely NOT use it on an engine again. Maybe keep an old belt around just for this task.

Yup! You are correct. I never reuse the belt for reinstalling and running the engine. And to install the pulleys use the exact same procedure! I do keep a spare belt around just for removing and installing cam sprockets. I am glad it helped out!! ~shaun

Default Cam Pulley Bolts with Company 23 Tools and a HF 10mm Hex on a Breaker

So here's an example doing it with the tools on an unopened JDM EJ205. I'm not a big guy, and it wasn't that much fuss. It's similar (but with AVCS) to when I tore my 04 WRX EJ205 down.
