David Brown 885 leaky sed. bowl

[drf64]

Hi,

Newbie here with a DB 885 diesel. Bought the tractor 2 months ago and noticed a leak from the sediment bowl. I suspected the bowl and gasket were both at fault, but getting replacement parts has been a crap shoot. I ended up ordering 2 bowls. One appears to be the correct diameter but is too long. The other is too small in diameter by just a few mm. I finally decided to try replacing it last night and what a mess! First off, why is there no fuel shut off between the tank and the bowl???? Second, after I got the bowl off, it does, as I suspected, have a chip in the glass at the top which i suspect keeps it from sealing. Since neither of the new bowls fit, I replaced the gasket and tried installing the old bowl, but it still leaks. I even tried two gaskets, but it leaks.

Does any one know where I can get the correct bowl and gasket for this tractor?

Thanks, Dan.

I know of at least 3 different fuel bowl sediment filters for the 885/995/1210 series, two different sizes of glass and one steel. You can always order the part from a dealer by your serial # and get the right one, but I have fixed the glass bowls before by cleaning the glass well with alcohol, and using some silicone caulk to fill in the chipped out area, waiting a few hours for it to dry, take a razor blade and cut it flat with the rest of the glass, and then putting it back on.

Good luck!

is this the sed bowl on the lift pump?

Thank you. I would like to try it. If I had a good way to shut off the fuel it would be earsier.

That is correct. Thanks.

50$ gets you the entire shebang.. .. me? i'd just be done with it and have a new lift pump and all..

Very tempting. The only thing I need to be sure of is that this one is not the longer sized sed bowl. If it is, it won't clear the crankcase cap. I will call them tomorrow and ask about it. Thanks!

Have the same lack-of-fuel-shutoff problem on my Case 1194 (a rebadged DB), when I want to change the fuel filters I run the fuel level down as far as I dare, run the tractor up a steep embankment and park it. If done right, no fuel leakage. Then do the job, then let it roll back down to level. PIA, I agree, but I don't do it often enough to motivate me to put a shutoff in...

If you're convinced that the diagram posted above by soundguy is correct, the bowl for the 1194 should fit yours - it's part number K961733, Messicks says they have one in stock. The gasket is K34065

I just replaced a sediment bowl/lift pump on a Case 1390 (david brown). It mounts upside down with the bowl on top. Moisture had collected at the bottom where the zink casting is and corroded a pin hole through it. It was a small leak that was hard to see because the pump is mostly buried behind other stuff.

Okay, so here is what I did:

I ordered the lift kit from the above link. However, it was the larger sized sediment bowl and wouldn't mount in the standard configuration because it couldn't clear the crankcase cap. That's when I realized that the whole thing could be rotated by removing the six screws that hold the diaphragm together, and reassembling it one notch counterclockwise. It puts the sediment bowl a little outside of the cowling , but I have a loader on the tractor and figured that would protect it pretty well. I guess that remains to be seen.

Of course once i did that the fuel lines wouldn't reach so i replaced the line from the tank with standard 1/4" rubber fuel line. The connections to the inlet and outlet on the lift are tricky. I don't think anyone makes this size thread connector any more. So I saved the male connectors and rigged the inlet to a short piece of 5/16 brake line that thankfully fit tightly through the connector on the sediment bowl size inlet. The 1/4" fuel line fit snugly over it. I left a little slack in the line up top, in the tank end, in case it starts cracking.

I used 1/4" brake line with brass compression sleeves for the line from the outlet to the fuel filters and bent it by hand. I then bled the air and tightened everything down.

It now runs fine and no leaks!

thanks to all who replied.

those fittings are likey a common flare fitting used in fuel applications...
