I've got a DD6-71, Da book says the oil strainer should be "cleaned with the approprate (sp) cleaner" so what is "approprate" (agian sp) and what is clean or better than that are they still around to buy from some where? | ||

As a mechanic, if I had something similar that I wanted to clean, say an old oil bath type air cleaned, I would probably let it soak in a solvent tank for a while with a stream of solvent running over it. In a pinch, or in the field, I'd probably use one or two cans of aerosol brake cleaner with it sitting on some shop towels spraying until the fluid coming off of it is fairly clear. Brian | ||

I didn't think about the brake cleaner. I washed it in gas and tried dish soap as well, which I realize I have to get clean out very well, but none of these were working to suit me. The thing is big enough to be hard to fit anywhere to clean it. Brake cleaner will do the trick I think. How clean to I need it, I'm sure it was at least light grey when it began it's life, now it's a real dark grey at best. | ||

I guess my brain has been in neutral or maybe even reverse. I've been wishing that it was warmer so I could crank up the pressure washer and not have to re-winterize it. I think I'm going to go smell some diesel fuel or something to get my head back in the game. I HATE BRAIN FARTS!!!!!!!!!!!!!! | ||

I have for 17 years took a 5 gallon bucket put 2 gallons of gas in it and let the wire mess filters sit for 20 minutes then move them up and down then stand them in the air to drain and dry for an afternoon. John | ||

This isn't wire it's cloth, I haven't got to cleaning the air filters yet. I never seen a strainer like this thing that is supposed to be cleanable. I suppose I'll see a lot of things on this ol' girl I've never seen before though so I'd better get used to it.  | ||

Try Castrol's Purple Stuff, it's quicker and VERY effective. I use it exclusively to clean my oil bath air cleaner. Mainly because it's far faster than any other method I've tried. Brake parts cleaners are great, but you'll use about 5 cans . Too much momey to suit me. !!! Cheers...JJ | ||

No problem John, I've got to get them out and clean 'em up too I just haven't gotten to that point yet. Jayjay, how hard is the purple stuff to rince out? Will it come out at the car wash?? | ||

The brake cleaner will work, and it leaves no residue. It MIGHT take three cans...maybe, but JayJay, Nick has already cleaned it with gas and soap... and you can usually find that brake cleaner on sale at the local Checkers or Chiefs or AutoZone. Brian | ||

Diesel fuel works for me cleaning up dirty parts that have oil on them. If oil is not involved in holding the dirt on the parts, I would just use the car wash. Spic and Span or TSP will do a nice job on stained surfaces, but remember to use gloves when handling either. If you were to start to install an air cleaner that you just washed in fuel or thinner while the engine is running, you might get a surprise. I did that once, and the engine kind of barked at me. It really had no problem burning off the fumes. Just one more opinion. Tom Caffrey PD4106-2576 Suncatcher | ||

You guys that use gasoline and diesel fuel to clean parts make me shudder! All you have to do is go to an oil distributor and buy cleaning solvent in bulk-- you can get it in 5 gallon pails to 55 gal drums. If you bring your own container you can just have them fill it and pay the price per gallon. And this stuff not only cleans the best but it doesn't smell. And you can also use it for starting BBQ charcoal-- it is the same stuff. | ||

If this is a cloth or paper core filter, I would throw the damn thing away and buy a new one. My opinion on trying to clean it is that u will never really accomplish it, even though it may at some point take on the appearance of clean, it is always going to have particles retained in it that reduces it's effective ability to do it's job. Considering the relative cost of a new one and the time involved to try and clean a used one, it ain't worth the effort and you for sure are not going to achieve the effectiveness of a new one. I don't clean paper air filters either, they quite simply don't come that clean and lab tests have proven it. It's all part of owning a bus, so figure it in and replace those items that are intended to be replaced periodically. | ||

I'm still trying to figure out what paper filters would be in something as old as a 1947 GM 3751. Oil screens and breathers are usually steel mesh. | ||

I dug out my 1953 Detroit Service manual and it shows the "Oil Strainer Assembly (Coach)" that attaches to the oil cooler. It says the element is washable with clean fuel oil or other suitable cleaning fluid (like solvent!). It says to use a fine bristle brush, not a wire brush. The book doesn't say what the strainer element is made out of. | ||

Your book says the same thing as mine Geoff. I would like to find somewhere I can get one but I'm affraid my local DD outfit would be a wasted phone call. They don't seem to know a great deal about the older plants. I agree with James M about not really getting the thing clean but I don't really have a choice at this point. | ||

Hey I just looke in my parts book and found and interesting pic. The thing I'm trying to clean isn't in the pic but the housing it came out of is and it holds two disposable filters. The thing Da book calls a strainer is where I found in mine a replacable oil filter with a NAPA number on it????? What are the chances of this thing not being put to gather right???? | ||

Nick My book shows two oil filters with replaceable elements, PLUS the oil strainer we were talking about (I thought). Only buses used the oil strainer, trucks used the replaceable filters only. If it helps my books show the oil filters as mounted on a pedestal-tube that drained into the oil fill tube. The oil strainer is mounted with the oil cooler housing. --Geoff | ||

I think mine is the same way (I'm at work and the book is on the home PC). The problem is the thing that I thought I needed to clean, the one long cloth "filter" is mounted where the two canister filters are. I don't have a problem replacing the "oil strainer" since it looks like a canister filter I'll treat it as one I just don't know wheather I need to try to find another long cloth "filter" like I've got or go back with what Da book says. My DD parts man did track down the numbers but didn't have 'em in stock and there are no numbers on the cloth "filter". Ahhhhh the joys of a previously owned, and modified, antique bus!!!!!!!!! | ||

I went to talk to the DD man finally yesterday. A profitable vist to my surprise (I found the guy to talk to). He could only order my filter by the case and although I probably should have I don't have the spare cash to buy 12 filters at $12 each. I found an outfit that could order them so I've got two coming, one for now and one for the next time I need to change it and it takes three weeks to find one Thanks for everything, it was a lot of help even though I didn't know what I was talking about to start with. | ||

Nick, just *what* filter was it??? If you don't know give me the part number and I can figure it out. | ||

Hey Geoff its the oil filter that mounts horizontally on the lower part of the engine. I really don't know the part number cause what Da book says isn't what's in the bus. Da book says it should be 5570685 x2. Like I said though not what's in it. It has just one "sock" filter in it. Since it had an engine put in it in '83 I don't know what's right and what's not. I can't find any numbers on the engine so I can't get the right book for it, but if you've got any ideas that would help me I'm open for sugestions. Thanks all!! | ||

If it mounts horizontally is it a later model full flow oil filter. It uses a cannister oil filter which costs (me) 4-5 bucks. I don't know why it had a sock filter in it. You should find a newer 6-71 service manual it will have pictures of the newer oil filter setups. I suspect your engine is not the original and it has been replaced by a newer model 6-71. Give me the serial number and I'll see if I can look it up. --Geoff | ||

Geoff, Where would I find the serial number on it. I've looked everywhere I can get too and can't find one. Someone wrote on the back end that she got a new engine in '83. It also has the vertical cannister filter(which I'm not real impressed with the way it goes in and seals). It all looks the same as the pictures in the book I've got just none of the filters are the same. Like I said I would not be suprised at all if nothing on this thing is what is supposed to be there, one wire I've traced to the front was spliced and change colors four of five times, he ran an oil line to the front dangeling down along the belly, and if it weren't for sheet metal roofing screws(you know the kind with the big washer and rubber seal on them) the guy wouldn't have been able to do anything. Thanks a bunch, Nick | ||

The serial and model numbers should be on the side of the block, I don't remember which side, maybe you can't see it because it is on the firewall side? Also, if it is a replacement block it may not have any numbers at all. --Geoff | ||

Ok let's go with the idea that it is a replacement and it doesn't have any, then what do I do to find out for sure on my filters and such? |
