2nd Gen Timing Gears

[HanginInUtah]

Just some quick thoughts...
I'm in the middle of lost-my-head-gasket-fun and I'm tearing down the engine, but I cannot get the timing gear bolts loose! My 4R is outside on the side of the house, so I have a long air hose to use with my impact. I barely got the crank bolt to break loose, and only when I stepped up the pressure in the line and the compressor had cycled. So, one thing I'm going to try is moving the thing into the garage, using a short air line, as big as I've got, and see if that helps with the power to the gun.
But... just to make sure: are they left-hand threaded? Because the last thing I want to do is tighten them more and break off a bolt!
The FSM mentions a special tool to hold the gear while you undo the bolt. Not sure where I'd find one of those, let alone do I really want to invest the $$.

FWIW the bolts are standard thread and a PITA to crack.
I made a tool like the guy on Yotatech fabbed, and used that along with a 1/2" drive breaker bar with a cheater pipe to crack the bolts.

On the second page somebody MacGyvered C clamps with a 2x4 to hold the sprockets.
Anyway, the special tool can be found on ebay, just do a search for camshaft pully holder.
In the end it cost me as much to make the tool as it would have cost to buy the tool...
Hope this helps,
