Definitive Difference Between 7MGE & 7MGTE Oil Pumps?

[Shytheed Dumas]

So a search shows me...

1) There is a difference in Toyota part numbers, and
2) The pump body is longer on the gte pump due to longer gears, and more pumping volume.

If you don't have one of each to compare body length, and you have an Aisin pump that you got from somewhere other than Toyota, how can you say for sure which one you have?

What are the specific lengths? What is going to be different in the markings or numbers on the pumps?

This is why I ask... http://www.supramania.com/forums/showthread.php?t=71809

So which is it?

 

[Shytheed Dumas]

There's no way to tell if the oil pump in this thread is suitable for a GTE?

Anybody?




I wonder how many of the freshly rebuilt RK's were due, at least somewhat, to using a ge pump in a gte if it's that hard to tell them apart?

Jeff Lange and IJ both make a pretty strong argument that they are different in this thread: http://www.supramania.com/forums/showthread.php?t=39755&highlight=difference+between+oil+pump, but outside of having both pumps side by side, I do not see any way to say for sure which is which and I want to kill this deal if it's not a GTE friendly pump. Comments, please.

They are 100% different there's no grey area about this.

I don't have a pump out of a motor to measure sorry.

"blue" usually denotes GE parts though.

GTE is orange/brown.

Anyone have an answer for shytheed? It would help us both out. Thank you

I have been unable to locate a true GTE pump from any major aftermarket suppliers (Clevite/Melling etc). Being that it came from Advance Auto I am going to say it isnt a GTE pump.

 

[88YotaTurbo]

any luck with anyone finding a way to tell the difference.

Toga makes what they call a high volume pump, I believe it is a GTE pump. The housings are different sizes to accomadate the larger gears on the GTE from what I seen. I have a stock GE pump somewere I can dig out and check the size for you if that would help?

 

[88YotaTurbo]

That would help out more then enough. Maybe if you could take some photos of where you measured too.
THANK YOU

Heh, I might have to swap in a GTE oil pump just to see how high I can get my pressure...

 

[trydrew]

I have a gte pump laying around that i can measure.


Edit: Ok, the "slave" gear in the pump that was on my original gte engine has a radius of about 19mm and the a height of about 37mm. The caliper I used isn't the best, but what i've come up with should be enough to show how different the pumps are. Also the driven gear apears to be very similar in size.

Dang this thing seems smaller then I though it was. lol

I will measure mine tonight and see if the results are matching. Thank for your help..... BTW which gear is the slave?

 

[ValgeKotkas]

I have one GE (probably) pump lying around too. I could take some pics with measuring tape attached to it.

 

[88YotaTurbo]

anything will help.

 

[gofastgeorge]

The gears in the turbo bump are 37mm long.

 

[88YotaTurbo]

going to measure it right now be back with the answer.

[IJ.]

Ummmm someone has TOTALLY missed the point here......

We're talking about the internal pump gears as they affect volume moved per rpm not the drive gears

 

[88YotaTurbo]

alright thank you ..... I thought that was completely wrong.... Measuring that now too!@

 

[IJ.]

LOL no probs!

made me smile though.
