• but I swear that my cam sprocket is welded onto the end of the cam .  Whilst doing the timing belt on my new (to me) motor; I decided to do the belt PROPERLY per vince.  Tried everything I could throw at it.  Ended up giving up .  HOW THE FARK DO YOU GET THAT STUPID SPROCKET OFF   Did the belt the way I usually do it, and it came out closer than it was originally.  I think the timing was a little retarded before.  I just got the timing all done before I decided to take a little breather before reassembly.  threads are useless without pics so here are some from this cars outing last week on its final testing run before we start doing the LOOOONNNNGGGGG hauls

• Don't do what I did and break the end if the cam off.......it costed me $50 for a reground one.
  
  Back the bolt off about a quarter inch and get a puller, hook that up and tighten it up but not so much that it dents the sprocket. Next use a brass drift to tap on the base of the sprocket, you have to "shock" it enough to pop it loose.

• A block of wood and a hammer also helps. Just don't get and splinters lost around the cam.

• Drive a flat screwdriver between the sprocket and head,giving it some pre-tension then gently tap the opposite side with a wood hammer,always works for me.

• If you're gonna whack the back of the sprocket, be sure to completely remove the bolt, or you run the risk of breaking the nose off the cam. Just have a towel to catch the sprocket.

• had the bolt completely out.  and whacked the tarnation out of it.  Car is all put back together again, and running smoother than ever before.  took the time to put the lower timing belt cover on that was missing before.  thanks brett

• Ha ha... yup.. that sprocket can definitely have a mind of its own.  
  
  I have a pretty big puller which usually does the trick, but on a couple of occasions have "inherited" working on one where the sprocket nut was very clearly over-torqued.
  
  When this happens I generally just pop the cam caps off and pull the cam... for the cost of a cam seal my perspective is that much easier to wrestle with the sprocket further in the comfort of a vise.

• I back the bolt off a bit, poke a small screwdriver or drift in the little hole in the metal shield behind the sprocket, then give it a tap.  Never requires much effort usually.  The pump sprocket is a different issue usually.

• Stop being a big bunch of girls and get a dirty great hammer out and just whack it, gaylords.
  Oh, leave the bolt in the hole, undound to catch it.
  Straighten the covers later....

• i just tap it in

• 
  Just a few turns undone on the cam bolt, and whack from behind. Remove the two little allen headed bolts off the back cover if they are on there and plate will move but not distort

• Then get your files out and fix the spots where you've wacked it so the belt won't get chewed up from it. Why don't you use a wooden hammer or brass hammer? Better yet, how about a puller?

• i always had something in between the hammer and the pulley.  Its running smooooth and I'm getting it ready to take down to los angeles for bonelli in november.  yahhh.

• I remember saying "feck" & "arse" lots whilst doing that pulley once. Genius with the tinware going around the camshaft so it's got to come apart to get the head off. Mine was sintered too, so it was just begging me to give it an excuse to shatter.
