1999 Camry 2.2L engine
I purchased a rebuilt engine for my 1999 camry. I started to reassemble the new engine and found that the counter balance has a different pitch than driven gear than the crankshaft drive gear.The rebuilders said to discard the balancer ! Has anyone run into this problem?

Don't know about pitch but the number of teeth changed for both crank and balance shaft in 1994. How many teeth on the rebuilt engine, how many on the balance shaft?
The replacement engine did not come with the balancer? Was this a short block?
Installing a balance unit from another engine may require different shims to obtain gear backlash.
Owners have removed the counterbalance shafts, the engine seemed to run OK. Still there would be reason for them or Toyota would have eliminated them.

The balancer has a more course tooth than the crankshaft has.They will not meshup to each other.I called the rebuilder and they said not to use the balancer it is not required.The engine is a long block assembly from a large rebuilder.

It might have been better if the rebuilder listed the number of teeth on the crank when advertising the product as some rebuilders do.
Up to mid 1994 the number of teeth was something like 64-66, this was changed to 44.
As to what to do now:
Might ask the rebuilder if they have a balance assy off a engine year that will fit. All 5S-FE engines had a balance shaft system, they may have on in their scrap pile.
Find a blown engine of the right year and remove the balance assy.
Leave the shafts out when putting the engine back together. If you go this route there is supposed be an oil feed line that needs to be plugged. Suggest a Google search on removing the balance shafts for this model engine.
Members at the website Toyotanation may have further help as some have actually removed the shafts.

You bought a used harmonic balancer, as in crank pulley or a balancer unit that bolts to the block.
If pulley, it will index off the crank snout key. If the complete unit, yes the gears need to be timed both with each other and with the crankshaft drive gear.
