First, what is the best tool to use to get the balancer hub off? Will a pulley puller do it fine? It seems my hub may be gradually walking off because out of the blue, my supercharger belt is starting to fray on one side.

Second, I have been waiting for the day my motor blows up and I am worried it may be close. I have a random knock which seems to be coming from the upper end of the motor. Almost like the cam or timing chain area. It knocks once in a while with no consistency. I can duplicate it by slightly tipping in the throttle. I could only hear it with the s/c belt off due to the noisy blower. What do you guys think it may be?

Thanks, Mike.

 

Killed the motor already?

Prehaps a bent pushrod

The center bolt should keep the hub from coming off.

 

Already? I have had the blower on since last July

Never heard a bent pushrod so I don't know what it sounds like. Definately sounds "heavier" if you can imagine that.

The center bolt was loose enough that it didn't require any force to loosen. If I had my camera, I would have taken a picture. You know how you can tell where the seal rubs the metal shiny? The shiny part was sticking out about a 1/16" past the seal. I tried tapping the hub onto the crank more, but that didn't help. I tried tightening the bolt but that didn't help either.

 

I couldn't get the hub off with a puller so I just put the bolt back in and used a long breaker bar and it managed to pull the hub up onto the crank. So that problem is fixed now. Since I couldn't pull it off, I wasn't able to set screw it.

I tried to hear that knock again and it didn't do it. Very random indeed. I am just going to ride and see what happens.

 

Those hubs can be kinda tricky at times. I had a buddy that had one that WOULD NOT come off. used a torch to heat it used a 600 ft-lbs impact on the puller, hammered the puller, it wouldn't move. Ended up cutting it off (it was a stock crank and I had another one) to get the timing cover off We even antiseized it the last time it was put on. What I normally do is loosen the crank bolt a few turns and then use a 3 jaw puller and start crankin, after the hub breaks free and moves a little you have to take the puller off and turn the bolt out some more. I do it this way because if you pull the bolt out to far it has a tendency to bend I now own a whole box of bolts

 

I use a length of grade 8 threaded rod, no head on the end so you don't have to continue to back the bolt out after you move the hub back.. my puller however is a solid round 3/4" piece of steel with the center drilled and threaded... this helps keep the puller from deflecting and putting uneven pressure on the hub as it is pressed off the crank snout. slim.. if you still want to try and remove it, gimme a shout.. you can borrow my setup.. it works wonders and makes removal and installation a breeze!

Smokn, I broke the puller trying to get that thing to move. I have to take it back to Auto Zone and explain

Ok, thanks Chris. I think I will let it go for now like it is. I got the pulley back on all the way so the belt is good to go.

I'll give you a call one day and we can go over turbo101.

 

it is the easist way to remove the hub is to use Kent moore LT1/4 hub installer/removal. It so easy you would not believe. 1st time I use pulley puller (nightmare) the 2nd time kent moore tool come in, piece of cake.

 

Isn't that thing pretty expensive? I think I looked into one a few years back, but just couldn't justify the cost. I'm sure it works great!
