Timing Chain Inspection and Replacement

[Tynan918]

Is the fan, water pump, and harmonic balancer the only things I remove to get to the timing chain cover ?

I would buy this instead of the puller that doubles for steering wheels and this one is also an installer.
If you are going to buy tools you might as well buy ones that work well.

To make sure the current timing tab was incorrect did you ensure where TDC was for that balancer? When guys toss together motors on the fly the nearest balancer usally goes on.

Yes, if you're referring to the groove on the balancer

I dont see where you'd need the three jaw puller, NOT what you want to use to pull the balancer off with.
Good job so far getting it torn down.

Crank sprocket

Was out of my budget... I've watched a few videos of guys using the tool I bought to remove the harmonic balancer...

Just put something in between this tool and the harmonic balancer instead of putting the tool in the harmonic balancer/crankshaft bolt thread hole to avoid damaging the threads of the harmonic balancer/crankshaft bolt hole.

Yea, thought about replacing this one with a new one...

What's the difference between 7" balancer and 8" balancer ?

^^Chuckles^^

Certain set-ups work better w/a smaller diameter balancer for clearance issues. You're set-up gets the 8" balancer.

Thank you for the clarification !

By the numbers on your engine it is an early 80s 305 and came with the 6.75" balancer. Most 350s came with the 8" balancer.

All high RPM engines came with the 8" even it they were smaller displacement than 350 (Like the 302 in the Z28 and corvette 327s). The balancer is tuned to the RPM range the engine is rated at so high performance engines have bigger balancers. Some trucks might have bigger balancers too.
