2Z498 compressor - no tank, no motor, any good?

by james

Hi Bill,

I have come across a speedaire compressor model 2Z 498 in my late grandfathers workshop. I found the unit alone, unconnected to a tank and motor in an opened speedaire box.

There is no sign of a tank and motor anywhere in the workshop.

To the untrained naked eye the unit looks in reasonably decent shape (no apparent fractures or cracks to the housing / base and all parts seem to be solidly attached). It has oil in the cylinder and the intake/ exhaust ports look as if there had been threaded air lines attached at one time. The pulley wheel rotates freely as does the piston inside the cylinder. I can also hear air being sucked in and released on each stroke.

My question for you is, "What is the most efficient and complete way to determine if this compressor is still viable or was removed previously due to some defect." With no motor or tank to hook it up to, how can I decide if it creates and holds pressure and if it doesn't, what the problem is, and whether or not it is worth fixng and keeping it around as a backup.

Thanks,
James

James, the only way I know is to add a motor and and output with a gauge so that you can measure the results.

Other opinions are certainly welcome.

You should be able to get a repair kit for the basic parts here:

Hello Brian:

Greetings. Nice to hear from Gibson. It's been a while since I stood on the dock (wharf??)at the bottom of the hill. Here's to Bruno Gerussi et al!

First thing is to visit this page, and follow the guides to getting in touch with the supplier of Speedaire Compressors.

They will help, they promised me!

Next, Google compressor repair for your area and find the local "guru" for air compressors. There's almost always one. Bring your compressor to them and ask them to change the oil. Watch how they do it. Ask how they know how much oil to put in, and what type of oil is recommended.

Next time, you'll have all the info you need.

And don't wait 15 years to change the oil. It's a wonder that your unit is working at all. Ask the pro's how often you should change the oil in your compressor. Certainly at least every two years if you use it minimally, once a year at least if you use it often.

Third, check back on this site in 10 days or so for the launch of the ebook The Home Compressor. Many, hopefully all, of your home compressor questions will be answered there.

Cheers,

Bill
