My 2006 3.5L broke a timing belt, the broken belt wrapped itslef around the crankshaft timing gear/sprocket. I've got the balancer removed, the timing cover etc. Now I need to remove and replace the crankshaft timing gear because the little sheet metal "washer" that is welded on the outboard side is bent. I don't think I should run a new belt on it. So - has anyone successfully removed and installed that crankshaft timing gear WITHOUT special tool L-4407-A for removal and WITHOUT tool 6641 for installation?

I wondered about using a large socket, some spacers and the crankshaft bolt to re-press the new gear/sprocket in place. Anybody?

(ps - the heads are at the machine shop - so far it's good news, only one cylinder "might" have bent valves/guides, although the machine shop said it might have failed the pressure test from built up carbon on the valves and NOT because of being bent. We'll see.)

 

update:

Machine shop just called - there was NO damage to the heads. One head failed a pressure test - but it was atributed to a carbon deposit on the back side of the valve - not to a bent valve.

Also - I've discovered that Special tool 6641 with 12mm Screw and thrust bearing and washer (ie the sprocket installation tool) is used so that the timing sprocket doesnt get pressed too far onto the crankshaft. I believe that diligence in measuring the old and installing the new to the same spot will result in a properly installed timing gear sprocket - Hoping someone here can confirm.

 

I've got the crankshaft timing gear removal tool - and the old gear just won't budge. Any ideas?

 

A little dissapointed in the lack of responses I've received.

I finally was able to get the timing sprocket off. about 450 ft/lbs, some penetrating oil and a few taps on the end of the puller center bolt. repeated about 10 times this morning.
