I checked out those cam locks, and I think they look great. And they should serve their function well I might add. My only question is; in order to install the tool with a "worn" belt, will the pins line up, or will one need to tweak each cam into the tooth? Thank you. -John
I'm going to add more info to our website soon as there is a bit of confusion and misunderstanding on how these function.
First, I designed these primarily to hold the cam pulleys in order to loosten and tighten the cam pulleys. In order for these to fit, the relationship of each cam pulleys to the other is specific and critical. Based on belt slack or tension, it may be required to rotate one cam very slightly with relation to the other to get the tool engaged.
For a "lock and swap" of belts, please note the engine does not need to be at TDC. Orient the cam pulleys per the image below, install the tool to lock the cams, lock the crank, remove and replace belts. Note, because of cam timing, you may only be able to lock one bank at a time.
The other option is to flip the main body and not engage the pins and just use the tool as a pure clamp. This will not resist torque on the bolts this way though.
Feel free to contact me if you have other questions. Thank you.
