This tool locks the LH side cam sprockets from turning when the timing belt is removed preventing cam sprockets from spinning and eliminates potential valve damage.

Another big plus is this tool allows the timing belt job to be done by a single person with ease by locking the LH cams in place.

Took the hassle out

Great tool. You dont have to tighten it down very hard which leave some movement to turn pulleys to create slack or align if you are off a tooth(like this guy)

Essential for timing a dohc ej motor
Tim Dingle 4 months ago
If anyone has tried to a timing job on a dohc ej20 or ej25, they know a 2nd set of hands is crucial to getting it timed correctly due to the driver side cams being loaded to line the timing marks. This tool eliminates the need for those 2nd set of hands. Use: Turn the allen insert piece until both sink inside the driver-side allan cam bolt faces then lock them down once you get the timing where you want it. I find it easier to do the main sprocket first, then time counter-clockwise so you can work the excess belt towards the tensioner and get it on with ease. Be cognizant and hold the excess or it'll come off the driver intake cam and you'll have to redo it again. Great tool to have.

You need this tool!!!

A must have if you're thinking of doing your timing belt on your own. Made the change very easy and worry free that your driver's side will not slip out of timing. I simply put this tool on the cam gears, made sure the bolts are tight and simply removed the timing belt (following procedure of course). Don't cheap out, do the job properly with the right tools.

might have to play with the pieces that insert the cam gear bolts to ensure your cams are lined up EXACTLY. I give it a 5.

Perfect fit, held cams securely

Picked this up during a Company23 sale and glad I did. You can change a DOHC timing belt without this tool, but this makes it faster and more idiot-proof.

  • Q: 2012 Subaru WRX   Ethan WRX 4 months ago


    Using this tool, would I have to re-time the engine or is it as simple as place tool on remove, belt and other components, and install new belt and components. Or would you turn the engine by the crank pulley for the gear timing marks to align and then install tool.

    • A: You would line up all the timing marks on the gears then put this in place on the drivers side cam gears. You are then able to take off the old belt and install the new belt and idlers/pulleys.

  • Q: How many?  capilarybinkie 2 years ago


    Since there are 2 sides, would I need to purchase 2 of these? Or does it come with both?

    • A: This tool is for the LH side only (from driver's perspective). You can use this tool for both sides of the engine however, the right side cams are not under any valve spring load at TDC for cylinder #1 and will not move on their own like the left side will.

      Company23 2 years ago
    • A: Only one tool is needed to lock the LH side cam sprockets.

  • Q: AVCS compatability   Foxerwith92361 3 years ago


    Didn't see a specification, will this work with AVCS too?

    • A: This does work with engines that have no AVCS, Intake AVCS, and Dual AVCS. The included spacer is needed to manage the offset of the cam sprocket height on engines with Intake AVCS only. Hope that helps!

      Company23 3 years ago
    • A: Yes this will work with AVCS

  • Q: Left and Right Side?  mikeweaver119268524 3 years ago


    Can I buy two and use them for both sides, or will it only fit for the left side? This would have been an awesome tool if I knew it existed when I did my timing belt, however even if you lock one side the other side can still move.

    • A: You can use this tool for both sides of the engine however, the right side cams are not under any valve spring load and will not move on their own like the left side will.

  • Q: A bit confused here!  PhilBarnak 4 years ago


    So you dont need this tool for the left cams right ? if ive read right the passager cams can turn freely with no problems..? but different story for the driver side.?

    • A: The LH cams of the engine refers to the left side of the engine from the driver's perspective (or the right side if looking at the engine from the front of the car). Only the LH cams require this tool because when the engine is at TDC for cylinder #1, the cam lobe is compressing a valve spring and the cam will snap into a relaxed position when the belt is removed. This tool holds the LH cams in place so they can't rotate. The RH cams are not compressing a valve spring in this position and therefore do not need to be held with a tool.

      Company23 4 years ago
    • A: The passenger side cams usually do not move when you remove the timing belt, but the driver side cams are under load and will jump when the timing belt is removed.
