I never did a write up. Attached is the Official Timing belt procedure, which is lacking. At the bottom there is a link to the engine reconditioning manual.

On page 21 of the reconditioning manual, it tells you to remove the vibration damper to get the timing belt off. This is not necessary. On the bottom, there is a plate behind the vibration damper. Take that plate off and there is just enough space to slip the timing belt off with a little persuasion.

When installing the timing belt to the crankshaft, you got to push the timing belt vertical as far you can, then move it to horizontal. There is a wall sticking out from the block, the timing belt needs to go between that wall and the timing gear on the crankshaft. Later on if you go to slip the timing belt over the camshaft gears and your come up short on belt. Is is because you got the timing belt on the wrong side of that wall.

There is one bolt that hides a little behind the vibration damper, I think it is the lower bolt of the Idler. You cannot get a socket on it with the vibration damper on. you can only move a wrench a bit at a time. The way to get it broken loose is to remove all the other bolts. Tap the Idler clockwise, give the Idler a good rap counter clockwise, repeat until the bolt is loose enough to turn with a wrench.

There's just not a lot of you tube stuff related to the 960. But it's pretty much the same as doing the timing belt on an 850 or V/S70. You'll find plenty on those cars. I'm pretty sure the timing belt replacement is exact on the 5 cylinder white block. With the 960 giving you a lot more room than the stuffed in sideways FWD.

Thanks sharing the recondition manual and pdf. That helps but I will also look at some videos to make sure I have the right tools and enough gumption to tackle the job.

On interference engines, you get 0 chances....nail it, or hire it out.

Now I'm scared. That's kind of why I stick to repairs that won't 'brick' the car or leave me getting a tow truck if I screw up.

It is nonsense. After the timing belt is installed, turn the engine over by hand 720° (2X360°) clockwise, if there is an interference condition you will find it. This also seats the belt so that it does not slip.
