[JimmySmith]

[hammertime]

Moroso

[TheYellaBrick]

Melling.....Totally disassembled, deburred, blueprinted, super cleaned and oiled by myself.

[ashbros]

Don't forget to tack weld the pickup tube if its a slip in pick up tube...

[et7333]

anyone use the milodon:Small Block, Hi Pressure, Standard Volume -
Z 28 and LT1 factory equivalent. #18756

[Tod74]

I thought everyone was scared of the Melling pumps since they no longer use billet gears....

[OneBadGMC]

I was talking to someone recently who called Melling over that whole sintered metal gear thing.

Supposedly, it was misinformation spread by competition. I haven't called Melling directly myself though to confirm.

Someone on MOTORSPORTS Village(i think) posted that they asked MELLING about it and were told that none of their pumps use billet gears anymore. I don't want to lie so I will try and find that later .

[OneBadGMC]

Well, again, maybe that's bad info on my source's part. That's why I said I hadn't called yet to confirm it.

We use a Meling SELECT. Later J.Smith 4621 racing :D
x2 Available in +10% or +25% volumn, larger inlet hole, threaded pressure relief spring plug and the gear shafts go into the cover.
Then (like DD said) totally dissambled and blueprinted.

[jaxsmith]

Pops always said "We use a Meling SELECT. Later J.Smith 4621 racing " I dont change anything he says T Smith 4623 racing

[Tod74]

how do you blueprint an oil pump? What are the measurements and tolerances and how do you adjust them?

[cepx111]

Good question Tod, I just deburr everything real good, make sure everything operates smoothly, loc-tight the cover bolts weld pick tube and be done with it.

I've always run Melling HV pumps, never had any problems.
I have heard about the powered metal gear problem(s) but I have yet to see one that has failed>
I'd Like to know more about it and when the switch to powered metal gears was made.

Anybody?


Now if money is not a object then go with a Titan, they are bulletproof.

Thats hard to do when they don't answer their phone or emails.

[promod45]

Thats hard to do when they don't answer their phone or emails......... i agree but it might be your time zone difference i had that problem to but once i figured it out i got ahold of them right away and competion productssells there stuff to if you know what you want

[markdunlap]

I tried for months to buy CVR BBC oil pumps from Competition Products and direct from CVR. All I ever got was "They are out of stock" or "Production has been delayed" from both of them. CVR would answer my emails but never would tell me when I could get my hands on one. Competition Productd would just keep trying to upgrade me to a CVR aluminum pump which I did not want.
I wonder if they have actually ever produced any at any time?

[us7race]

Melling Select 10552 10% more Volume high presssure, Designed to be Happy at 70psi. Been running it for 2 seasons now with Very good Results.
It is made for a Bolt on or press in pickup tube but I ended up having to use a press-in style and welded it fully.

[THERATTLER]

I use Melling part # MEL 10552 around $50 bucks never a problem, has bolt on pick-up and steel billet gears and cnc machined gear cover,,hard to beat for the money,,,,Paul

[THERATTLER]

found this on melling select pumps , according to this they still use billet gears , just an observation,,,,Paul

Melling "M Select" Performance Oil Pump w/Extended Shafts
The drive and idler shafts have been extended to allow for additional support into the cover. This eliminates dynamic shaft deflection at increased rpm levels. The cover is doweled to the pump housing to assure alignment of shaft bores. The housing and cover are CNC machined and manganese phosphate coated for wear and rust protection. The gears are billet steel. The relief valve features a screw-in plug for easy spring change. Includes intermediate pump shaft. "C" = anti-cavitation, designed for high rpm.

[et7333]

This is a copy off the Melling site:

10552
High volume performance oil pump.
10% increase in volume over stock oil pump.
The 10552 is manufactured with the drive and idler shafts extended to allow for additional support in the cover eliminating dynamic shaft deflection at increased RPM levels.
The cover is doweled to the pump housing to assure alignment of the shaft bores.
Screw in plug retains relief valve spring instead of pin.
Relief hole in cover uses screw in plug instead of pressed cup plug.
All bolts are self locking socket heads, with the wrench supplied.
The housing and cover are CNC machined and phosphate coated.
Includes intermediate shaft with steel guide. Uses both 3/4” bolt on or press in screen.
The lower pressure spring is included to reduce pressure if desired.
Patent No. 5,810,571.

There is nothing mentioned about Billet Gears.Here is a link to their site:

[altune]

Par racing says they use just a $45.00 simple regular volume and pressure pump. Not sure why, possibly they run their bearing tolerances tight.

[et7333]

Any luck with buying a cvr pump yet?

[markdunlap]

I haven't.
The 1st ones to get them will be Competition Products. Might check with them to see if they know when.

[BEAST477]

I have a CVR iron pump. Got it just over a year ago. Last one they had, aluminum pumps were on back order then and still are last I checked.

[TheYellaBrick]

[MEMRACING62]
