Does the Harmonic Balancer bottom out on the oil pump or slide thru the center hole?
Because I Installed Mellings 295HV pump and Harmonic Balancer won't seat correctly, checked the specs and it should go on without a hitch , but it won't seat all the way to correctly line up the fan belt! or the old seal marks.
I put the 295 next to the 295HV pump before installing and it was a little taller but Melling countersank the face plate bolts to offset the height difference, but does the Harmonic Balancer bottom out on the oil pump or slide thru the center hole?
and is it to much volume for the ON3 twin Turbo Kit?

Thanks

People usually shy away from high volume on single turbos and opt for high pressure.
Are you using a double roller chain also?
Are you 100% sure your crank gear is on all the way, the fron cover is completely bolted down, and your balancer is bottomed all the way?
The balancer butts against the oil pump drive/crank gear.
What timing set did you use?

I have a loose clearance motor and decided to go HV with the twins.

I have the stock single chain

I've run the impact gun forever so i'm thinking its seated all the way.

Timing set is stock.

SO DO I NEED TO MILL A SMALL AMOUNT OFF THE Balancer ???

OR switch to a high pressure pump instead ?

You need to use an install tool and not the stock bolt and impact gun. Good way to break the bolt.
Otherwise, either put the balancer in the oven for a bit or use a torch to heat only the hub then install it. Youll prob see it go on alot easier. A small amt of lube in the balancer and on crank can help also.

I was going to grab a 150mm bolt, washers and bearing to install the balance tomorrow morning , I did heat it up to 175-190* and put a little anti seize on the balancer.

I don't want to bust off a bolt or jack up the crank.

so Im going to go to O'Reilly's and check out the difference in offsets on the oil pumps if the balancer rides on the pump gear!

I"ll post back the findings in an hr

I said the balancer rides on the crank gear/oil pump drive not oil pump gears. it never touches the oil pump gears. It seats against the crankshaft cam gear/oil pump drive.
Youll need more than 190* to get that metal expanded enough.

how hot does it need to be?
I'll throw it in the gas BBQ tomorrow.
I'm waiting till 430pm Las Vegas time to get a 295HV to the Oreilles by me.

The oil pump wont matter. The gears will be different .499 vs .420 from m295 to m295hv.
Most people say 250-265 for 20 to 30 mins....or until golden brown.

stacy moore

so your saying the balancer should slide on with heat, proper tool and a little anti seize.

and that the 295HV only has larger pump gears not thicker gears stopping the balancer.

The balancer never comes into contact with any part of the oil pump gears at all.
No antisieze at all.
Use some moly lube in both areas.
Then heat it, use a proper tool, and you'll be fine.

Thanks
for the help , I will get the proper tool and get it finished up.
I just wanted to make sure I wasn't going at it wrong and crushing the pump gears or ?

Thank You

for the help yesterday, I went to the Hardware store and got all thread and 1.5"x 3" pipe .... and what do you know ... it slid right on like butter.

Do not....i repeat....DO NOT put that balancer in the oven. You will more than likely destroy/distort the rubber, and when it comes apart while running will take out your crank and whatever else it happens to hit. Use a handheld propane torch and heat up the snout of the pulley, and it will install with nearly zero effort. Personally I don't like to use the threads on the crank snout for anything other than to bolt the balancer on.

To late homes he already did it.

Hope it doesn't come apart on em. Will keep an eye out for a thread titled "now my balancer came apart and destroyed my motor and hood".

Youd be very surprised how many have done the oven trick and are still running tens of thousands of miles later. Its not that big of a deal.
Pounding a balancer on with a hammer seems like the much worse idea, yet people do that also.

Don't care how many people have gotten lucky, it's a bad idea. Like I said, if you want to do the heat method to install the balancer that's cool..... just heat up the snout of it, this keeps the rubber from getting super heated/compromised. You gain nothing but potential headaches by putting the thing in the oven.

250-265 *shouldn't* be hot enough to hurt the rubber...

I like the torch method with the correct all thread install tool on my stuff.

Game ova

You shouldn't even need an install tool while using a propane torch. When you get the snout of the balancer hot enough.....it just falls onto the crank.... no tool needed. I wish I still had the old balancer that I tried the oven trick with, speaking with live in the flesh experience here. One may get away with the oven deal, or he could end up with a real mess under the hood. Id rather not take the gamble.
