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.

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.

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.

excellent tool to have, worked on my 05 subaru STI with Single AVCS
Calvin 3 months ago
used this on my first subaru timing belt job and i have to say this tool makes the job much easier. i mean of course you could be cheap and do it without this tool and save your self $50, but after working on cars for a living i say money is well spent on tools that help you struggle less. the spacer thing is used on the NON AVCS gear to help space it to the AVCS gear depth the bolt with the magnet that goes into the cam gear itself is 19mm, and the bolt that holds it in place is a 17mm. i just used an open end 19mm wrench on the magnet bolt and then a ratcheting 17mm wrench on the lock down bolt worked fine for me. this is used on the side with the cams that has the valve spring tension, so from the car its the driver side camshafts OR standing in front of the engine bay its on the right side by the battery.

BUY THIS TOOL! Great price and good quality product!

Would not want to do the timing without this tool. Very reasonable price. Con : On the second timing job, the "bolt/stud" combo with this tool, did allow both cams to rock out of time a few teeth, upon re-installation of new timing belt. Re-installed tool several times with same outcome. Ordered a new tool and worked perfect first time. Hopefully I just purchased a dud the first time. Still highly recommend this tool!


  • AnswerQ: How many?  capilarybinkie 1 year 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 1 year ago

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

  • AnswerQ: AVCS compatability   Foxerwith92361 2 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!

    • A: Yes this will work with AVCS

  • AnswerQ: 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.

  • AnswerQ: A bit confused here!  PhilBarnak 3 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.

    • 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.

  • AnswerQ: Placement  CraftyCraft 3 years ago

    This is for the USDM's driver side, right? The LH description is throwing me off from what I have been reading. Can you confirm?

    • A: This tool is for the USDM driver side cams.
