Specific parts # confusion for 2z498 compressor

by Jake
(Umatilla County, OR.)

I rescued a speedaire air compressor from a friend of mine that was going to take it to the dump. It had been sitting outside in the rain for quite some time, as the piston had seized up and the head was completely full of water.

I cleaned everything up really nice, and I'm currently in the middle of rebuilding the compressor pump. When looking online for certain parts for my 2Z498 compressor, I am confronted with two different options of parts; 2Z498(A) & 2Z498(B)

My main concern is that I'll be ordering parts from the internet. If I end up ordering the wrong parts, I'll be waiting (and probably paying) for "shipping" to return, and again receive, the right parts!

So I guess my question is, what is the difference between the 2Z498(A) compressor pump, and the 2Z498(B) compressor pump?? The answer to this question could save me from quite the inconvenience, if there even is a difference at all! Thanks in advance..

I did notice the part numbers for both pumps are the same, and the second tier of the head I mentioned before is the "Valve Plate."(not shown in the drawing)

After finding the true drawing for my Speedaire Pump 2Z498, I was able to see that the gasket kit they offer DOES contain the Valve Plate gaskets that I need.(although the use of those gaskets are not depicted, hence my confusion)

I wanted to be sure that the kit I needed didn't conform to change as the pump design did, as I have had this problem in the past with buying auto parts for my truck.

Thank you for your interest in the matter and also for your input!

Good question.

Have you noticed different part numbers for the two pumps?

The only difference I see is the drawings for the two are different, but when you go to parts list, they are the same part numbers, just different numbers on the drawings.

Maybe ask the supplier(s) you're considering?
