Hi Guys,
Does anyone have the dimensions for and or a 3D print file for the bar that locks down the Cam shafts?

Tool No: 00072195300

Thanks

Anyone? I could use a file as well. I can also CAD it up if someone can give some measurements of the OE tool.

Anyone have a picture of the tool in question? Just trying to figure out what it is to start. :)

I don't know that I've ever run across a procedure where you lock down the camshafts for timing. There are certainly tools that lock the cams down for removal, as they are apparently susceptible to breaking if you undo the caps incorrectly. The setting of position relative to each other is driven primarily by correct insertion into the right chain links, and relative to the crank by the sprocket, which has some screws to hold position.

I don't know if that helps or clarifies things.

ETA: Just to be clear, this is what I'm talking about - https://928srus.com/products/cam-shaft- ... v-86-to-95

I made some out of wood and threaded rod that have worked just fine.

Breaking a camshaft without using this tool? This is not even remotely close to plausible. Cam caps will let go well before the camshafts.

I just removed my cams without the cam tool. Just loosen the cam caps little by little and work your way around so they all loosen a little at a time. Ive "heard" the cams can be brittle and can crack/break if you are not slowly releasing pressure across the camshaft equally (using the above method), but if you are careful and release the pressure equally around the head, it shouldn't be an issue.

For timing belt related work, that will be a flywheel lock (locks the crank in place) and then you set the exhaust cam position using the mark on the cam gear.

If you remove the cams, you must reset/recalibrate the intake/exhaust cam timing. The cam gear is adjustable to allow for adjustment of the intake cam position in relation to the exhaust cam. Refer to the FSM and use a dial gauge to measure the depression on the #1 intake lifter (for S/S2 motors) before setting the position of the exhaust cam/cam gear. 968s require additional, somewhat more complicated steps, such as pressurizing the variocam solenoid while setting the cam position/adjustment.

Once thats done then you can position the exhaust cam to its cam gear timing mark position as you would with a normal timing belt service.

Certainly not the case. The cast cams are very brittle and many have been broken by removing the caps unevenly and stressing (bending) the cam enough to break it.

I stand by my statement. Challenging a comment without experience nor expertise is contrary to the whole point of the Carpokes forum. Most of us are here to help avoid headaches, not create them.

Sorry Sir, I seem to always forget that you have designed the wheel.
