It had the same drill holes on on front side facing away from motor. I do not recall a counterweight on the timing cover side.

Engine Mechanical / Electrical / Harmonic balancer
« on: May 20, 2018, 02:34:57 PM »
Question for you guys about the harmonic balancer on a BBC 454. How do you match one to your flywheel? The reason I ask is that I changed mine out (as it was bad) and purchased one from AutoZone. I just purchased the one for my motor and it looked the same as my old one. The issue I am having is I have a vibration once accelerating and on plane. Nothing at idle. The vibration is continuous. I’m not sure what flex plate I have as I did not build the motor. If they do not match could it cause a continuous vibration?

Question for you guys, is an "H" bar drive line balanced when new? The reason I ask is that I had my u joints replaced and since then I have had a vibration when getting into the throttle and on plane. I have changed the alignment on my motor several times and I still have the vibration. Pump is good as I already rebuilt. Any and all help is greatly appreciated. Thx.

There "C" clips on the inside of Caps that retain them on splined yoke. Should my "H" Bar be level with no angle?

Now looking at how the motor is sitting the front is not parallel to the pump. I was told that the u joint that is bolted to my motor should be at the same degree as the shaft that goes into the pump. Kinda at a loss a bit as this is the first jet boat that I have done work on and everyone tells me that the angle of the drive shaft needs to be between 3 and 5 degrees.

The flex plate was not removed when the motor was pulled out. I just pulled the motor to do all of the seals since it sat for a few years.

Motor mounts are good. Flywheel/flex plate is good. I had the motor out to fix the seals and then replaced the u joints. Ever since then I have had a vibration. I know the mounts weren't move on the stringers so I am sure I have enough movement on the yoke. How would I check the movement without removing the driveline from the motor, or is that what I would have to do?

I currently have a vibration when I take off and once I get on plane it dissipates but when ever I get on the gas it becomes more noticeable. I have went thru the pump and all good there. I have adjusted the degree pitch of my motor as well (did that several times). I had new u joints put in last summer when I fixed the seals on the motor. Could it be my u joints? Possible incorrect ones? I am currently at a loss and any help would be much appreciated. Thx.

By chance did you have time to look to see if you have an Arrestor for a Holley?
