Hi a bit more slack on our '99 sable 165K engine, had to r/r the water pump, it was
only 3 months old before it leaked at both weep holes but was lifetime from autozone.
So was easy to r/r the timing cover as it was leaking from bad head gasket(s) that were replaced short time ago.
The oil pan gasket was also replaced when I did the transaxle when it wore out, that is when I checked the slack in the timing chain and planned to replace it next time I was able to do so.
Once you line up the crank and camshaft to TDC
, timing dot on the crankshaft gear 12 o'clock high,
the camshaft TDC
dot is 6 o'clock low.
It will be a snug fit but little oil on the shafts and gears, line up the crank keyway and then slide it on a bit, then you can slide the camshaft gear on slowly, you will need to like up the key and keyway.
It will take a short time but it will slide on little at a time.
Be sure to add a drop of RTV to the key on the crankshaft before you slide on the crankshaft pulley.
Engine has nice smooth idle, I can tell the difference compared to the old chain,
I used Cloyes brand made in the USA.
