[s-cars] Broken Cam Pulley, AAN

[capnkidd]

Hi,

I can't help but but jump in here and remind you that the caps are sometimes
brittle.  I broke one trying to "straighten up" a cam and getting a new cap
was a real pita. Fred's right;  if the cam(s) is/are properly installed, you
should be able to use the _old_ timing belt to align to TDC, especially with
the plugs out.

Cheers!

Jim Jordan

 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
