Has anybody built a parts washer? I plan on using an electric fuel pump to pump the cleaner but am particularly interested in how others have built the filter system and what kind of cleaner they use.

parts washer

i have made one that works well i started with a center sump oil pan from a 3208cat (worked for a cat dealer for30yrs}then a fuel transfer pump driven by a small elc motor of a dish washer. the filter from a diesel engine(the primary one wich is a fine screen)so it can be washed, welded some legs on the pan and made a lid workes great. the center sump allows instalation of a heavey skreen to put stuff on above the varsol. a center sump pan of a 302 truck engine would work, but if you live near a cat dealer and smile at the servicr maneger you will likely get some freebees when he knows what you are up to ,a fuel pump off a oil furnace would work also. have fun. i also have a old dish washe in my shop for final cleaning works well, v8 heads fit. soap and hotwatter is very good for final cleaning engine or trans parts. be sure to sray lube the parts after wash as rust will develop fast. have fun cliff

Thanks so far for the input. There is something worrying me at the moment: I inquired about industry cleaners that are offered for such parts washers and found that these are TREMENDOUSLY expensive where I live.

What did you do? It's possible that such cleaners are cheaper in the USA, but probably not. These cleaners usually contain kerosene, is it possible to use normal kerosene which is probably cheaper, or does anybody have a special receipe for a cleaning mixture?

Cleaning solvents

Yup they are very expensive but then since they are constantly recycled in the parts washer it may not be as much of an issue as is generally thought. for a homemade washer I woudl like to use 1/2 of a 55 gal drum so I can put a complete tranny or engine block on the washer. Now one will need to do a secondary cleaning before painting to make sure no solvents are left to interfere with painting. Might be best to just bite the bullet and get a replacement washer pump from your parts supplier as some of the jury rig deals wind up costing as much or more as doing it right in the first place.

I just use plain diesel fuel in mine. Works well and when you leave it sit for a while all the heavy solids sink to the bottom and the remaining diesel is fairly clean.
I've found it works well at getting rid of the large amount of crap that accumulates and then I just give whatever I'm cleaning a quick degrease and hose. Job done.

BTW, my parts cleaner is a 60 litre drum on it's side and cut in half. It's welded to a frame with wheels and has a large(ish) pump underneath it.
Don't know what the pump was originally for, but it was cheap at a junk sale.

Yes.

Go to www.homier.com. Buy Homier item #04725. You cannot find a better pump for the price.

Get a drum. I had a friend at a dealership save me a 55 gal that had windshield washer fluid in it. Ideally I would rather have had a smaller one. Ask around and you might get one for free like I did.

I used an old steel kitchen sink. Use the drain too. I took a piece of screen wire over the bottom in case any small parts were to find their way to the drain. All free.

I added a flash lid. Just a piece of sheet metal hinged.

Get about 4 ft of 3/8" vinyl tubing.

The rest you can figure out. Mounting of the sink, rigging a spout.

Do you really want to build one when you can get one of these?

Roger, I don't own one of the HF washers but I know of a couple of guys that do and it seems they are one of the items from HF that work really well. One of the fellows rebuilds transmissions and the other runs a small engine/lawn mower shop and both use these things a lot, seems like it would make more sense than trying to build one.

Just a thought

Yes those HF washers are fairly cheap but I live overseas and there are no HF stores over here...

I see the cut-in-half-barrel washer has been built before, but I'm surprised that some of you don't use a filter, I don't trust the dirt-will-sink-to-the-bottom approach and want to filter the fluid before leading it back into the tank.

Using diesel would be worth a try, it's about 1.75 a litre, the dedicated cleaners are 3-4 bucks a litre (cheapest offer I found so far).

My filter is simple but it works well. I suspended a bowl under the drain. The drain has a piece of screen wire doubled over in it. The bowl catches any thing else heavy that might make it through. The fluid just continually overflows the bowl and the heavy stuff fall to the bottom of the bowl. Makes it quieter too. I also have my pump a 1/2" off the bottom of the tank.

I thought about sinking a VW Beetle oil screen in the barrel & picking up the fluid from the middle of the screen, just like a VW oil pump does, then pumping it through a large inline fuel filter like fuel-injected Fords use. This is purely theoritical, I haven't tried it yet.

In the meantime the washer is nearly finished, see how it turned out in the pics below. Sorry they're not very good quality as my digital camera is only a cheap one.





The pump is a fuel pump from a Saab 9000 (my garage neighbour is a Saab crack and removed it just because it has run a quarter million km, but it's working fine). The transformer was rescued from trash, was from a low voltage lighting system and delivers 5A at 12V. There's a rectifier located behind the on/off switch because the transformer delivers ac.

At the moment there's diesel inside. The fluid passes a screen when flowing off the half barrel, and at the bottom of the pump pickup there is a normal fuel filter as used on motorcyles and the like.
