Hello,

Do I have to remove timing belt in order to remove and replace the Crankshaft Pulley/Harmonic Balancer?

In other words, what is the least amount required in order to replace the crankshaft pulley/harmonic balancer.

Thanks for your input.

 

No, it is not necessary to touch the timing belt.

The timing belt sprocket is behind the harmonic balancer and does not have to be disturbed.

 

Millball is correct.

But that raises the question: why not? By the time you've removed the harmonic balancer, you're more than half-way through replacing the timing belt. Unless you know that it's brand-new, I'd just keep going and replace the belt.

Why is one pulley half of the job? First you have to get to it, and then you have to get the bolt out. The spec is 181 ft-lbs, so count on having to put at least 200 ft-lbs on the bolt to remove it. The SST looks to be about 12" long, so you'd have to resist 200 lbs with one hand! So I recommend a shop-built tool to keep the crank from turning. https://www.yotatech.com/forums/f116...h-3vze-137934/, plus lots of others cited in the post. The one that won't help is one of the most common suggestions: using the starter motor. I don't doubt you can eventually remove the bolt (with the chance of a lot of excitement when the socket wrench slips), but you still have to put it back in. The starter won't help there, so you're going to need a tool or other method to hold the crank.

 

Timing belt was changed 3yrs ago. Thanks for the input folks.
