No
The 265, 283, and early 327's, did not have one. EVERYTHING after 69 had one. I have heard of them comming out, but, not usually without catastrophic damage to the radiator. Who ever assembled it, could have forgotten to put it in, as the harmonic balancer, presses on pretty tight.
First remove the old one using a puller that you screw into the harmonic balancer there is a key on it so you can not put the new one on wrong just use the bolt that holds the main pully on to push the balancer on
no its not i paid 50.00 dollars for balancer and put it in about one hour
Remove the belt. Remove the bolt that attaches the harmonic balancer. Rent or purchase a harmonic balancer puller. Follow the Instructions with the puller and remove the old balancer. Install the new balancer making sure to line up the keyway, a little oil helps. Put the retaining bolt back in and tighten to manufacture specs.
If you put the wrong harmonic balancer on theres probly a 99% chance your going to damage the internal parts of your engine such as bearings ect.. most harmonic blancers run around the 75 % mark brand new so its worth it to get a new one if yours is begging to fail
The crank and balancer are keyed. It only goes on one way.
Slide the balancer on the crankshaft snout as far as you can by hand, then put a harmonic balancer installation tool in and crank it down until it bottoms out. If you can't afford to buy the tool, you can make one with a piece of 1/2-20 threaded rod, a nut, and some big thick washers. Put grease between the washers so they will slip easily while you're tightening the nut.
It is normal. Right=Tight Left=Loose. I just replaced my harmonic balancer on tacoma yesterday. I had to put a breaker bar and 2x4 for support. Then very very briefly hit the starter and it broje the bot loose. I tried about everything else and it didn't work.
They will fit, but the engine won't perform very efficiently. Also, 283's didn't have accessory bolt holes on the ends.
Just put the cam bolt back in and tighten it down, it will go back in easy
yes all sbc manifolds will fit, when you get to cyl heads then you will have trouble since most aftermarket are for 350 bore which is larger
