by Joseph
(Seekonk, mass. USA)

I have a speedaire compressor 2Z498B and need to replace the crank shaft, needle bearings, valves, oil seal, and all the gaskets. I called grainger but really did not get too far with them, I find it hard to believe that there are no parts hanging around some where on the internet. I've tried but keep ending up w/ no luck. can anyone please help. Sincerely, Joe Gaspar ( email is, )

2Z498B compressor needle bearings
by: Doug in

Hey Jake -

Did you by chance get an industry standard part number?

That number would be the best for people who need the bearings.

2z498 pump
by: Jake

Hey, I was browsing through the questions here to find an answer to my own, and noticed your asking about needle bearings.

I also have a Speedaire 2z498 pump which I just did a rebuild on.

The needle bearings are indeed very hard to find!

If you can get your old ones out,(my pump sat for 3 years full of water which made extraction a real P.I.A) take the most presentable one with you to an auto parts/machine type shop to match the dimensions. I went to several different small engine repair, refrigeration repair, and even vacuum repair shops with no luck finding them.

The auto parts/machine shop I finally came across tried to cross reference numbers from my needle bearings with no luck. Then as a last resort, he called one of their bearing suppliers and gave them the dimensions. Of course they had to be ordered, but the next day I had my two new needle bearings in hand for less than $20.00 and they fit perfect.

Hope this helps you out as I know the frustration this simple problem brings, and if you have already found them.. maybe this can help another frustrated person out!

Indeed. it's one of those things that's easy for some, hard for others, depending on what skills and machine access (free or cheap) you have.

speedaire 2Z498B
by: Anonymous

Yea, I was thinking about going to a machine shop but I don't think the price it would cost wouldn't be worth it. It's to bad, that compressor has been with me for a long long time. I guess it's part sentimental value that's playing a role.

...seems the main thing you have trouble with, if you can't find a used pump with good crank, you'll be looking at a replacement pump.

Unless you know a hotrod place that machines cranks from scratch.
