my oilpump exloded

[Dirty Harry]

You could always just convert to dry sump.

The only problem is that nobody offers upgraded ones for the h22. Go figure that they make them for f22, but not the h. The only thing that is offered is an upgraded gear, and some other custom mods that you can do with a washer or two.

Well he is one of the few people that has an upgraded f22 so he should have no excuse for not having one then. They can be had for only about $150 so it's not a big deal.

good catch. I saw that he ordered a h22 pump gear, so tiredness + not fully reading =

[fast93accord]

the f22 and h22 have differnt part #'s for oilpumps, but the gears themselves are the same part #...
yeah, i ordered an H22 prodrive. My oilpump was so new it still has the parts warranty on it so, i got a completely new pump i'm going to put the prodrive gears in. I'm using an OEM balancer. New crank timing gear and balancer shaft gear, new key, new bolt...
The prodrive gears are on backorder, but i'm getting it dropshipped from the factory so i can get it asap... Depending on when they get here, thats when it will be done... and i'll be back at the dragstrip...
I'm trying to buy a jeep wrangler this week also... i need something to drive everyday and to take to the mountains to go snowboarding...

i agree with fearitt....u r only as strong as your weakest link and building up a motor and not changing vital stock compontents will def be a bad idea. when u put that much more hp on a already tired motor, stock crap will break.....doesn't mean it is the pulleys lol....why is everyone so eager to blame the pulleys on everything that goes wrong. as i say it is either the driver, the installation, or the lack of upgraded pertinent parts that contribute to broken parts

do it right the first time around and save yourself a lot of trouble in the end

his motor was freshly built, im betting he put a brand new stock pump on . . .

First off its the ur pulley, cause its undampened. Harmonic vibration travels through any type of material, thats why honda has/uses the polyurthane ring on the stock pulley to absorb the vibration. If the ur pulley had polyurthane ring built into it, then it could absorb that vibration. But since it doesn't, that vibration would cause your so called tired oil pump gear to vibrate and shatter cause that oil pump is right next to your UR PULLEY. Thats why most racers use the fluidamper or ati crank pulleys. Second, stock oil pump gears are made from sintered metal. Fine powdered metal that is placed in a mold and and pressed into shape. So surely the stock oil pump gear is weaker then an aluminum billet oil pump gear. True these oil pumps are seeing more output then what honda intended but there are many others that haven't run into this problem until they use an aftermarket crank pulley or have extreme hp/torque levels.

It was definatly the pulley that caused it. I know this because the oilpump is not the only thing that got damaged. The oilpump was brand new.
The cam gear and balancer shaft gear, on the crankshaft, ride on each other.
They are now trash. They had marks on them where they sit together that looked like cast iron. The crank pulley bolt, on the washer side of the treads like 5-6 threads are somewhat worn down. All these parts were ok when i put the motor together.
The bad harmonics caused all this damage. Pretty obvious.
If these parts were not damaged, and only the oilpump was shot, then maybe i wouldnt think it was the alum crank pulley. But all these parts were damaged....
BTW, i'm not running the prodrive gears. They wont have them till the 28th. Not to mention i've seen a lot of broken ones... People have mixed reviews about them...

[accrdpower]

r u sure it was installed correctly and u didn't rev to like 8k rpms all the time? that the main reason shit happens. i'm still not convinced it was the pulley but i sure do hope u get all your stuff fixed.....good luck man! i guess i have been luck with my UR pulley set....over 10k miles and no harm done yet even with the way i beat the hell outta my car. let us know how the repairs come out.

[N1ghtM0nkey]

Alright ladies, here we go.

Leave the gosh darn diddly harmonic balancer ALONE!

Period. If it's worth it to you to chance destroying an oil pump or sending random vibrations through your motor - be my guest.

To the guy asking how vibrations travel through a rubber belt to the crank:

"As the cylinder fires, its crank journal pulses forward and then rebounds, creating what we call vibration, and more power means more vibration."

They don't. The damper is there to help absorb vibrations caused by combustion, or just normal engine use. Check out the link, it will elaborate on this.

Funny.... I tried to warn people on this forum off of the UR crank pullies( or any aluminum one) about a year ago and I got shouted at from all angles cuz people here were all for them. My how attitudes change, can you say bandwagon hhahahahahaha......

[accrdpower]

my attitude hasn't changed! lol i still am all for alluminum crank pullies. i think it is the drivers fault if shit happens bc yes honda oil pumps are known to be for SHIT! do yourself a favor and get a better oil pump....it called research b4 u put parts on! again over 10k miles on my crank pulley and no issues have arrived and i freakin slam on my car all the time. and i do plan on upgrading my oil system (pan, pickup, pump) in a few months! o and if u ask around the only thing that seems to go is the oil pumps on honda's.......if the oem crappy oil pump is replaced, all of a sudden no one has any issues. hmmmmmm no band waggin for me

I just read the story that n1ghtM0nkey posted . . . and it basically says that undampened crank pulleys are bad . . . I mean, it does it a hell of alot more elequently than that, but still, it was enough to convince me to never use an un dampened pulley.

[accrdpower]

it all about research b4 u buy....the only thing that really is affected is the oil pump.....so if u r really nervous bout something going wrong, buy a better oil pump i'm not nerved at all......bring it on bitches bring on some good goood good good vibrations ahhhhhh, good vibrations nananananananana nanananaananana......i'm picking up good vibrations... hehehe

hmm . . . well, lets see . . . if your oil pump blows, and you dont realize it, you could kill your engine from oil starvation . . . thats not enticing to me at all.
