On the 617.952 you wire or otherwise tie the timing chain to the camshaft gear so it does not jump teeth (look for more complete instructions on this job). Then you remove the end cap on the timing chain tensioner, remove the spring and check it for worn coils, remove the timing chain tensioner and housing with the piston/plunger still in it.
After you do that you have enough play in the chain to pull the crankshaft gear forward enough to get at the Key. You need to be carful.
When you go to put the timing chain tesioner back on you need to pull out the piston in the direction it would move when it applies tension. Install the timing chain tensioner housing. Then re-insert the piston/plunger (don't shove it in hard let the spring do the pushing) followed by the spring and the end cap with crush washer.
