oh yesss baby.
Working by torchlight in the garage (it's a private rented one with 50 other cars!like a parking lot).
Lubricated the arm tensioners.
Removed all plugs.
Replaced the alternator belt.
Turned the crank using the alternator belt and hand on crankshaft pulley to tighten up the belt on the non tensioner side.
Pulled on the tensioner and locked in the nut!!
Same on both sides.
Checked timing. SPOT ON to the milimeter.
Replaced averything except the timing belt covers (painted them also).
Started her up and a sweet alfa came alive again. Couldn't get her out as I was in the middle of a storm!!
Anyway I idled her until she reached 85 degrees - revved her nicely and all sounded very smooooth.
Have to give it a test run tomorrow and make another video to see if you notice the difference.
As the alternator belt was off I felt the water pump pulley and it felt ok.
Was a fraction, just fraction of movement (milimeter range), but I think this may be normal.
Alternator bearing was also smooth.
Might just loosen the right blet tensioner a fraction - no whine or hum but it felt a tad tighter than the other side.I don't want a snap when the engine gets really hot.
They expand quite a bit if you feel it when cold and hot.
I think when cold you shouldn't be able to turn it more than 90 degrees by hand without a lot of force.
