are you going to rig up an element filter or the traditional felt rectangle?
Funny, I got my compressor for the exact same thing , I want to mount it on my 33 gallon Craftsman oil-less compressor tank .
How long of a belt does yours have? I have a new one that was the wrong length . if it's fits, it's yours for shipping in a small flat rate box
How are you going to do your swap? When our local Sears closed I bought several broken oil-less compressors thinking I could fix them and flip/sell them. Good thing I paid less than scrap for the lot because the motor shafts were all sheared/broken. I ended up with a bunch of 20 & 26 gal compressors with basically brand new tanks, bad motors and all the other stuff (regulators, pressure valves, etc.)
Neighbor is closing down his shop and moving, he came by to shoot the s*** (he knows my beer fridge is always full) and offered me the older 1980's compressor. I needed another compressor like I need a hole in the head but what the heck... it was free. Worst that happens is I put it out on the curb and the scrappers will take it away. He said "it works", was good compressor, they used it in his shop for years, etc.
Compressor he dropped off was an older 1980's belt driven horizontal 20-gal. When I turned it on it immediatley started hissing out of several pin holes in the bottom. I guess that's the only thing I don't really like about horizontal tanks. Would be nice if the base of the tank was curved or if the drain valve was at one end so you could use/keep the compressor on a little bit of a slope.
I have a new (manufactured in August 2015, was floor model at Sears, I bought it broken in 2017) horizontal 20-gal tank from oil-less compressor. I thought swapping everything over would be easy except the handle is different and everything on the newer tank is in different places. Some people are comfortable welding pressure vessels... I'm not.
I cut the flat plate off the rusty 20-gal horizontal belt-drive tank, laid it on top of the clean oil-less horizontal 20gal tank... And realized that the center hole from the belt drive doesn't line up with the two tank ports... and to slide the belt-drive mounting plate forward enough to make it work, stuff starts bumping into the tank handle (compressor head, pulley, belt guard, etc.).
Basically what I did was slide the belt drive mount plate back on the tank so the compressor would fit, then measure and raise up the mounting plate enough that I have clearance for all the valves and ports. That part was easy, the belt-drive mounting plate is 1/8" thick, I have a bunch of 1/8" metal, a bandsaw and a welder. All I did was weld on four tabs extending where the motor side of the plate was welded to the old tank so new mount plate sits up about 3-1/2" above the top/center of the horizontal tank.
But that still doesn't solve the problem that the mounting plate for the oil-less tanks is 7-3/4" by 7-3/8" at the back/wheel side of the tank and the belt drive mount plate is something like 21" x 9". Had to weld an extension to the front of the mount plate for an anti-vibration foot to steady the front (compressor side) of the plate. I'm not exactly sure how it's going to work (still making it) but it's coming along.
If your 33-gal is vertical it should be super easy. I'd use two lengths of something like 1" angle iron, drill and bolt it to the oil-less mounting bracket and then screw or weld the belt drive bracket to the angle iron. My biggest concern with a belt drive compressor/motor setup on a vertical oil-less mount plate would be balancing the weight. The belt drive oiled compressor is SO MUCH quieter and doesn't vibrate nearly as much as the Craftsman oil-less models (the 20-gal belt is way quieter than my 26-gal oil-less). I'd just want to balance the weight evenly enough that you don't end up stressing the welds on the 33-gal tank.
If your 33-gal is horizontal hopefully it'll be big enough that you don't run into all the issues I'm dealing with. But also part of what I'm doing is trying to make something that looks clean, nice, new, legit, etc. Can't really give someone a total hack-job, Frankenstein compressor as a gift.
Belt:
I'm not sure what size this is. It's a 6-groove flat belt. I looked it up quick and saw part numbers like CB-215, CB-222, etc. I assume the 222 and 215 are lengths. I was going to give him the compressor with a little bit of spare oil, original and spare belt. I'll find out what size I need and PM you. Thanks for the offer.
Air Filter:
I'm not sure. Haven't gotten that far, haven't really thought about it yet. I'm guessing that an element style would be better but looking at the head, I'm not sure how I'd rig up something like that.
I really like how the Emglo KU compressors have filter elements. Seems much simpler/easier than the ****-tastic Craftsman method.
Wow this reply got long... What are you going to do about your air filter? I'd love a NPT threaded inlet port but the Devilbiss doesn't have that. I guess I could use much thicker gauge steel, goop on some RTV and weld on a NPT female port. Just not sure how strong the two screws are that are tapped into the head. Any other ideas? Interested to hear what you end up doing or what ideas you are thinking about.
There were 2 styles for that pump. One uses a thick felt rectangle (you can get them on eBay cheap enough). The other style had a block-off plate in the same rectangular space with two threaded holes for a pair of screw-in air filters (they looked like solberg style).
You can look up part diagrams and see both styles. I've never actually come across any of those pumps with the screwed on air filters, only the felt ones.
Heh. Interesting. I'll have to go back and edit my reply to The Cobbler. This compressor definitely has two threaded screws in the head right by where a filter would go. I assumed the screws were for a cover or something to help hold the felt in place.
OK this makes a little more sense. Thank you for the heads up. Yes, I have the two screws like this but don't have the filter element part, that was missing. Any suggestions? It seems they are all Devilbiss Z-D27194 compressors. I'll search for a blow up diagram. Are those solberg style filters decent? Can you still buy them? I don't mind making up something custom as long as it has a very easy to obtain, generic/universal filter. I don't want to be going through all this effort to give someone a headache down the road...
Interesting, just noticed that the belt pulley wheel in that pic I linked says something like C&F CHINA, has three balance holes drilled and looks like part number on it. Mine has a "265-102" and a much smaller "2.62" stamped on the back/compressor side then only an arrow and one drill/balance hole on the front side. All of my casting marks are from 1984 and 1985. Bottoms of pistons have a 5 where something looks like a date reference stamp.
