water pump pulley hits harmonic balancer
Has any one had to pull the hub on the water pump forward that the water pump pulley bolts up to about 3/8 " to clear the harmonic balance on a 454? This is my first boat and I have been restoring for almost two years It is a 1980 24' pantera. I would like to send a pic and see if some one can fined something wrong with it. I am trying to get it in the water this June put have a lot of other snags.
Thanks Todd |
Re: water pump pulley hits harmonic balancer
Once on a small block, I found that the balancer was not pushed back onto the crank all the way to the seat. If felt as if it were bottomed but it really wasn't, removed it and checked and found that it was hanging up a little bit. When it bottomed it was fine.

Did that twice. all the parts are new and was told they should work.

GM has long and short snout water pumps, you may have the wrong water pump, or the wp pully may not be the right one.

88fount33,
Make sure you have the correct harmonic balancer for that engine. |
Re: water pump pulley hits harmonic balancer
do you have a grinder? jes kidn, are you sure you have the correct balancer? there are several different od balancers avail.

Re: water pump pulley hits harmonic balancer
It happened to me one time. Luckily, I had a smaller pulley that cleared it fine. Later, I found the original pulley was warped.

Re: water pump pulley hits harmonic balancer
Yes I did .checked everything that the group has said.talked to marc at bam then used a puller and moved the pully out.No problems.

Re: water pump pulley hits harmonic balancer
Was the tit on the center of the hub still going threw the center of the water pump pulley?
Tried to send a pic but picture size was to big. |
Re: water pump pulley hits harmonic balancer
Yes on mine there is still some shaft left.My thought is the person at the factory that builds the things had a good lunch and had to much vitamin M for desert which can cause any thing from a slite mishap to a full blown FUBAR.I don't know. :drink: I do know that one monkey don't stop no show.James

Do these pulleys and brackets look like they could be right ? For a 454 and what pulley runs the sea pump.
|
Re: water pump pulley hits harmonic balancer
Mine looks exactly like the setup above. I will tell you from experience that you must take the water pump pulley off if you pull the balancer. I did not realize until I bent the pulley and the shaft on the water pump. :(
The clearence is real close, like mentioned 1/8 of an inch. |
Re: water pump pulley hits harmonic balancer
On yours what pulley runs the sea pump?
|
Re: water pump pulley hits harmonic balancer
Harmonic balancer.
|
Re: water pump pulley hits harmonic balancer
Is it the middle one on the balancer.
|
Re: water pump pulley hits harmonic balancer
Is there a specific reason you are not using a crossover instead of the recirc. pump?
|
Re: water pump pulley hits harmonic balancer
I was told by the machine shop that it would be more reliable and keep an even temp through out the block. The guy I'm talking about built motor's for Outerlimits. What do you think ?
|
Re: water pump pulley hits harmonic balancer
My .02 double check everything again,if all else fails pull the hub out just enough to get your clearence.Stay away from the Xover in till you put on the blower.Buy you friend at Outerlimits a beer :drink:

Re: water pump pulley hits harmonic balancer
I see your point about the recirc pump, just don't run too high of a thermostat temp in salt water. Looks like you're putting together a nice piece. I hope you post some pictures when it's done. My good friend has a 24 Pantera he keeps at my place for the winter. I think it's a much more fun ride than my 28 Cigarette. Good luck.

Re: water pump pulley hits harmonic balancer
Your bottom pulley looks different than mine. My balancer pulley has three grooves with the center on being the smaller one that drive the seawater pump. The inside one does the alt. and circ pump the outer does the p/s and circ. pump.
The center groove of the circ. pump pulley remains empty. |
Re: water pump pulley hits harmonic balancer
Yea that makes sense I'm going to get that 3 grove crank pulley.
