[s-cars] Broken Cam Pulley, AAN

[Fred Munro]

Hi Jim;

If you sheared two pulleys, I'd suspect one or both of your cams is binding.
This sometimes happens if the caps are installed improperly or torqued
improperly. Have you verified that the cams turn easily in the bearings?
There shouldn't be enough resistance to shear off the key.

Relax, have a merry Christmas, and fix it on Monday!

Merry Christmas to all!

I need a new cam gear/toothed belt pulley for my miserable S4. I installed
all the lifters today. After I torqued all the cam bearing caps down. I
reinstalled the old timing belt to hand spin the engine a couple of times
before I
replaced the timing belt and water pump. I was turning the engine by the
crank
bolt. Everything seemed fine until I realized that everything was turning
except
the cams (the valve cover was still off) The little tit that slides into the
cam sheered off of the cam gear. I removed the cam gear from my spare AAN
and
I sheered that one off as well. I am so pissed off that I'm almost laughing
about it. I even removed the spark plugs before I started so I could see #1
TDC
and so release any compression while I turned the engine by hand. I'll order
two new ones on Monday. I was thinking of TIG welding the little piece that
broke off the gear, but I'm out of time for today and I'll try not to be so
angry
for the rest of today and especially tomorrow. I'll have to wait until
Monday.

Happy Christmas/Merry New Year!

Angry Jim
