Cleaning Recovery Tank

69-er on Wed August 10, 2011 10:28 PM User is offlineView users profile

I bought an old Snap-On ACT-4100 (Sun MRC-400) station. It's been sitting for a few years so I am replacing all the typical maintenance items: the desiccant bag, oil cylinder, and master filter.

Another item I need to look at is the recovery tank. I have no idea what is inside. To prevent possible contamination during use, would it be feasible to remove the valves and other fittings to clean it out? What would be a good solvent? A typical flushing fluid?

Also I left a message with the parts dept 1-800 number. Are parts still available?

Thanks!

Open it up and inspect it. If there is any sign of rust (corrosion), then replace it. Clean it (just as we flush components) with a cleaning solvent (A/C flush) that will remove the residues; rinse, repeat, and dry it out well. At least you can inspect your work here, and it may help understand why so much effort and confirmation processes should be used when we flush the components we cannot internally inspect. One more thing, if the residues do not come out, it could be sealer or who knows what; replace it.

Hey Larry,

I just got a used MRC 400 and need some parts, oil, desiccant, master filter, basically all the stuff you were looking for. Did you ever find a place to get parts?

Thanks,

Doug

Just flushed a couple recovery tanks last night. Boy, that plug is NOT easy to get out. Needed about a 6 ft cheater bar on my wrench to coax it loose. Inside looked good though - no rust.
