My glass reservoir is broken. Can it be replaced without replacing the whole unit? Ifso,how is it removed?
The glass can be replaced, and this is becoming slightly more common as some units are 30+ years old. The seals and gaskets are all available separately as well. The 4 bolts that hold the glass onto the bronze base need to be unscrewed. When reassembling with the new glass with a new gasket, be sure not to over tighten the bolts, as it can crack or break the new glass. It just needs to be snug enough that the gasket can do its thing.

Is this jus the sight glass or does it come with the plug and o-ring? If not what is the part number for the plug and service kit.
It does not appear that the glass does not come with anything else. The link to the ARG series with all replacement parts is attached so if there are any other components needed, you can find them easily. https://www.groco.net/media/file/file/a/r/arg-series_6.pdf

How can I remove the sight glass to get the basket out for cleaning?
How do I remove the cap.
Hi Jason, How do I remove the cap. Is it the clear plastic cover with three indentions that look like a place to unscrew it. How do I get this off to access the basket? Thanks, Larry
I meant to say glass instead of strainer in my first response. The GLASS does not get removed. After removing the cap you can pull the strainer out.
Thanks Jason... Larry
Yes that's the cap. Turn it counter clockwise to unscrew it. If its too tight by hand then use a spanner wrench. It fits into the indentations.
The basket is not removed. There is a cap at the top of the strainer that is removed for access to the basket.
I would buy from Jamestown again
It was an exact fit and arrived promptly
Bay City, MI
I would buy this product again
Its for my boat Motor cooling system. The product would be better if it was made of glass and not plastic.
