Pulling crank timing gear: What tool/method to use?
Trying to put on a double roller timing chain set while doing the cam swap. Have a couple of different gear/pully pullers, nothing working right?
On the same line, best way to install crank gear and ud pulley without specialized harmonic balancer install tool?
Any thoughts on these lines appreciated. Any specific tools and sources for them also appreciated.
Thanks.

Gary,
My 2002 Corvette Service Manual says that you will need the following tools to remove and install the lower timing chain sprocket:
Removal - Kent-Moore tools J 8433, J 41815-2, and J 41558
Installation - Kent-Moore tool J 41665
Kent-Moore can be contacted at (800) 345-2233. Their web site is www.spxkentmoore.com
Good luck with your project. :seeya

Here's how I did it:
Put a 17mm socket on top of the head of the stock crank bolt and then use a good set of pullers. Worked like a champ. ;)

Putiing it back on whack the crap out of the center (only) with a hammer against a short 2x4.
There's a simpler way to do it - you don't want to mess up the crank journal/bearings up front and cause yourself bigger problems down the road. There's no reason to ever take a hammer to it.
Just flip the old crank sprocket around backwards, and use it against the shunt end of the new crank sprocket - kind of like this: |= =|, if you can see where I'm going, and then use the old crank bolt and 'walk' the old sprocket on so that it seats the new sprocket as you go. Once the new sprocket is seated, then use the puller to yank the old one back off - voila - new sprocket seated, and you never once had to use force on the snout of the crankshaft.

To help make the gear install process a little easier, put the gear in a disposable pie tin and pour enough oil over it to completely cover the gear. Then place it in the oven at about 150 degrees for about 20 minutes. Next, pack the crank snout in ice for about the same time.
The final step is do to the install very quickly; remove the ice and take the gear out of the oven, then immediately install the gear (before the crank heats up and the gear cools).
As an added benefit, "cooking" the gear forces some oil into the metal's pores which helps keep things turning smoothly. In fact, you can do the same thing with the chain and cam sprocket ;)

I finally got it, just a matter of getting the right 2 arm puller. After trying three others, the OTC Grip-O-Matic No. 1025 did it like a champ.
Thanks peeps!
