OBA part 1. Identifying a York 210 Compressor

I wanted to do a step by step as complete as I can writeup of my York 210 Onboard Air compressor setup. So lets start with the heart of the system the compressor.

I had a friend pull a York 210 for me and I was pretty sure it was a 210, but like usual the negative in me had to prove it. First off normally there is a tag identifying exactly what you have. Is it a 206, 209 or a 210? Theres the tag way and there is the pull the clutch and look at the tip of the crank method. My York was missing the Tag.

Im not a York expert by any means and Ive been told that York 210s are pretty easy to spot due to their shape. However I wanted to be sure so I spent a few minutes and pulled the clutch/pulley off to verify.

Tools:	Time:
Few hand tools 5/8 - Bolt aproximately 3-inches long	Aprox 15minutes

This was a pretty easy task to do. Just keep in mind your working with an all aluminum compressor. Written by kizer, if you have any questions or comments about this install visit

This is the tag that should be on the outside of the compressor. Now you could trust the tag or simply spend a few minutes and pull off the clutch/pulley.

First you need to remove the bolt that holds the clutch and pulley assembly inplace..

Inside the pulley/clutch you will find threads. The threads are used to remove the clutch.

Insert a 5/8ths bolt. I used a 3-inch bolt to make sure I had enough threads.

Use a socket to tighten the bolt. I placed my hand on the clutch and slowly turned the rachet. What you are trying to do is tighten the bolt down which forces the clutch/pulley off the tip of the crank.

The clutch and the pulley should just slide off with ease

Looking at the end of the crank.

This is the backside of the pulley/clutch. The notch is the same as the end of the crank

Looking at the end of the crank. There is a sharp edge opposed to a beveled edge. If it had a beveled edge it would be a York 206. A Deep grove would be a 209.

Now looking at the crank and using this diagram you can determine which compressor you have. Looking at this one you can tell its a 210

What a difference in bolt size. The bottom one is used to retain the clutch and pulley and the one on the top is used to remove.

Im no York expert, but the clutch looks like some big magnent of some sorts.
