Make sure that your front main seal kit comes with a speedy sleeve if you not replacing your harmonic balancer. There will be a small groove cut into the surface that might prevent your new seal from sealing.
You should. The both wear and they are usually matched sets. I would be very surprised if what you ordered doesn't include the gears.When I have the timing cover off, I have ordered a Cloytes timing chain.
Do I need to replace the gears?
You don't need to remove the timing cover to replace the seal. At 119k miles, replacing the timing chain is a waste of money and effort.When I have the timing cover off, I have ordered a Cloytes timing chain.
Timing chains are sold without the sprockets every day.I would be very surprised if what you ordered doesn't include the gears.
You learn something new every day. I have never seen anything but sets including gears.You don't need to remove the timing cover to replace the seal. At 119k miles, replacing the timing chain is a waste of money and effort.

Thanks, that was a great write-up and definitely learned a few things before I tackle replacing the harmonic balancer. Luckily, this is one time having a 2.5 cyl helps with alot more room. I have recently done my radiator,water pump and fan clutch so luckily I have already cut a notch in the bottom of my fan shroud so I can easily remove it without taking the fan off. That 2x4 idea for the re-install was ingenious. I'm going to bypass doing the chain at this time.I did this not too long ago and created a thread with some pictures. Hope this helps.

There is a tool for that. Harmonic balancer installer. Autozone (for one) has them in their loaner inventory.How do I get the new dorman balancer on?
That won't be so good for the rubber component.Can I heat it?
