Some of you may know from a post of mine a couple of weeks ago that I stripped the teeth off the duke's cam gear. I found a GM TSB that stated the gear can be removed without removing the camshaft by drilling holes in the cam gear and using a puller. Last night I started the work and the method I used was actually much easier than the new TSB states.
I actually was able to get to the cam gear in about 2 hours unhooking and disconnecting much less than the service bulletin suggested. Here's what I did:
Remove the following:
-Trunklid (not 100% necessary but makes it easier to work)
-Disconnect battery connections
-Ground strap to engine
-both accessory belts
-Throttle body and linkage. You don't have to remove the cable, linkages and fuel lines from the throttle body, the idea is to remove the these parts so when you lower the cradle the throttle body and linkage doesn't hit the trunk wall. This is not part of the TSB but taking this off saves taking off a lot of other stuff and makes the job much faster.
-Remove the clamp holding the coolant line going under the intake manifold. the clamp is on the trunk bulkhead, near the passenger strut tower.
Jack up the rear, place jack stands under the rear frame, NOT the cradle. I used jack stands with a piece of 2" x 2" steel tubing on top to get a little more height. Chock the front wheels!
Connect a hoist to the engine and place some tension on the chain.
-remove the rear wheels
-Remove the e-brake cable bracket on the driver side wheel well
-Remove the bracket for the brake hose on both side wheel wells
-Remove the 3 bolts on each strut holding the strut to the tower.
Revove the inner wheel well on the passenger side.
-Remove the two rear cradle bolts.
Lower the hoist and the rear of the cradle will drop down. You should be able to get the cradle all the way down to the ground and have enough room to remove the cam cover and work on the gear.
You should check very carefully as you lower the cradle that no hoses, cables or wires are getting stressed. I didn't have any problems with this: I didn't even have to remove any hoses or drain any antifreeze.
The TSB instructions call for you to remove all four cradle bolts and completely drop the cradle out, drain the coolant and take off a bunch of other stuff, including removing the struts from the knuckles. This way saved a lot of time. I just thought someone might find this useful and bookmark it. I've gotten a lot of good advice from this forum over the years, thought I'd try to share some of mine.
So...after taking off the cam cover, there it was, four or five teeth missing off the cam gear. I will post more about drilling the camshaft and gear to remove and replace it as I go.
