Default Camshaft Sprocket Removal Question

I removed my timing belt and now have the dilemma of trying to remove the camshaft sprocket without the "special tool" that Chrysler recommends using.

I saw a youtube that showed someone jamming a socket between the spokes onto the 10mm bolt holding the rear cover on and easily remove the sprocket bolt.

Mine isn't that easy. Cylinder #1 is at TDC.

My question is: there's a lot of space (play) between the sprocket spokes even with the socket jammed between the them. How much rotation can I allow the sprocket before the intake/exhaust valves hit the piston.?

Should I put the T-Belt back on then loosen the camshaft bolts?

Help

Okay, ... if the timing marks are all aligned then all the intake and exhaust valves are closed? I honestly don't know.

You will have no problems doing what you're doing with the valve touching anything.
Use the socket (good idea, BTW) to hold the gear while loosening the bolt.
Ensure you tighten cam bolts to correct torque; the pin is only for alignment, it
will shear w/o proper torque.

If a cylinder is at TDC, one set of valves will be open slightly, the FSM
shows (at least on the 2.0L) retarding crank 3 teeth while aligning gears.

See attached.

Well I used the "socket jammed between spokes method".

The good news is that it worked to loosen the camshaft sprocket nuts... the bad news is that the rear cover cracked on both sides.

I had made me a wrench sort of for holding cam gears.
All it is, is a 18" 1/2" black pipe, with a couple chunks of flat iron(at at angles) welded to it. Chunks of pipe should work too. Make sure you set it to have room for torque wrench. I use this on Ford products too, and it works well.

That's a great idea... thanks.

Now I have a excuse to use my welder.

I know most people want to save a buck or two when doing their own repair work, however in this case I would recommend you invest in this baby for now and the future. I have used mine to remove and install many a cam shaft sprocket and crank shaft pulley. The tool is adjustable for various diameter pulley and sprockets, and fits in all types of slots and hole configurations. The cost is merely $24 plus shipping trust it will be worth the investment. Dont forget what you take apart needs to go back together and usually has a high torque, the sprockets are 85ft/lbs and the crank pulley is 100ft/lbs. Hope this helps you out.

Not too expensive- Too much stuff already though!

I don't see what's wrong with the socket on the time cover bolt method, though. Shear on the bolt is extreme
