.....then take a rubber mallet and give the crankshaft a few whacks while you are trying to pull the chain off the crankshaft gear. After a few whacks, I was able to break it loose. All of this can be avoided by waiting to remove the bearing brace/caps until AFTER this balance shaft chain is removed.

With the bearing brace/caps not installed (a mistake on my end), there is still too much tension on this chain. Take one hand (not shown due to working the camera) and try to pull the chain off the crankshaft.....

Timing Chain Tensioner Bolts - I used a breaker bar. They were pretty tight, enough that an impact driver couldn't loosen them.

Bearing brace! Recommend not removing this until AFTER removing the rear timing cover, balance shaft chain, and the balance shafts. By keeping this installed, it helps keep the crankshaft tight, which helps to loosen the balance shaft chain.
