I have this part:
Blower motor

Part# 51-24042-01

HP 1/2 RPM 1050
V.115 Hz 60
Amp 6.30 PH1
Capacitor 7.50/370

I look for this part number 51-24042-01 and it is telling me that this part number is being replace by 51-102500-04

On the box that I got it says that it can contain either of these part number
51-102008-07
51-101774-03

Well guess what I got part number 51-102008-07
Here is the spec of the motor that I got
HP 1/2 RPM 850
V. 220-240 Hz 60/50
Amp
Capacitor 10/370

So here is my dilemma, is this the right part or wrong part.

I came to this conclusion:
Old motor has 7 wires hanging out
WHT, BLU, YLW, BLK, RED, BRN, BRN

New motor
BLK, BRN, ORG

Also old motor has tapped in screw holes onto the body, the new one does not,
this is all that I found on the net about it:

• The 51-102500 series motors are service motor part numbers. The box is labeled as 51-102500-04, and the motor supplied inside will be either 51-102008-07 (Emerson) or 51-101774-03 (G.E./Regal Beloit).
• The end boss mounting holes are NOT tapped on these motors. Self-tapping machine screws (10-32 x 7/16 in.) should be used for mounting. The screw used in production is part number 63-100404-01, and we are working with our vendors to include these screws in the box in the future. In the meantime, equivalent parts should be available in most hardware stores.

Can someone PLEASE SHINE SOME LIGHT FOR ME...

Should I return it, and look for another, or is this really the right one....

Doesn't sound right to me; especially since one is 120 and other is 240 v; rpms off by 20% would reduce air flow, wiring wrong, etc...
Try to take the original motor or what you have written down to a bricks and mortar motor store; they will likely be able to help you at about the same price as on line IMO.

I am by no means an expert here, but you have the wrong motor. Your original is 1050RPM, the new is too slow, 850 RPM. The old was 115v, the new is 220v. Return and get another.

Return it, wrong part. The horse power,voltage and rpm need to match the original motor.

Sounds like Grainger to the rescue....

Since mine has more wires
Does that mean that mine is a 4 speed
and the new one I got is 1 speed

Go to Grainger, and get a 3LU83 motor and 2MDV6 capacitor. (Direct Drive Blower Motor, Permanent Split Capacitor, Open Air-Over, 1/2 HP, 1075 RPM, Number of Speeds 4, 115 Volts, Full Load Amps 8.7). Better match for your old one.

whole bunch of stuff on blower motors (this is A/C but same concepts) at:
http://toad.net/~jsmeenen/motor.html
might give you some background info all in one place for you to get up to speed a bit more.

Or, if you want to upgrade to a more modern, energy efficient model, there is always this:

I am seriously considering this one for my replacement on my newer furnace.

Forgot to Meantion
Will Grainger sell to the Public... Meaning can I just walk in and buy this part.
Because all the other HVAC place I go to, they will not sell me parts.... That was why I order it on-line with the Mainboard... The mainboard is good though

TJ_in_IL

Just for spits and giggles, I googled your p/n, and found it at patriot supply, for more money than the one at Grainger! WOW!! And who says they are always over-priced??

Grainger sells hvac parts to any body with money.
