 Topic: sediment bowl questions
Posted: 14 May 2011 at 8:19am |
I have some questions regarding the sediment bowl on my D14. If I screw the shut off valve all the way out, it doesn't leak, but if I screw it in to shut the fuel off, it drips non-stop. I'm assuming the inner gasket/o-ring is bad. First question, by leaving the fuel on all the time, am I going to harm anything? Will the fuel continue to flow into the carb and eventually into the engine, dilluting the oil with gas? Second, can the shut off valves be rebuilt? Is it just a couple of o-rings or does anyone sell replacement valve assemblies? I know you can buy the entire sediment bowl assembly (and I actually have a spare), but if I can only replace the valve and solve the problem, I'd rather do that. Thanks for the advice.

Most times that valve stem has a packing, just tighten the hex nut a little that the stem goes through.
If the float valve in the carb does not leak there is no harm to leave the tank valve open. It's just a good practice to turn the tank valve off.

Yup try tighting the packing nut and we leave the gas on our gas tractors on all the time and have had no trouble, if your that worried just pull the dipstick before each start up and look at the oil.

Also, when putting the sediment back on, just as it's starting to get tight against the gasket, twist the bowl a little, this will help it seat and less likely to leak.

Dusty's last tip is a great one that I also do, when restoring a tractor I always put a complete new sediment bowl on as driping gas will ruin a new paint job!!

Just my opinion but I always try to save the original valve assembly on any resto because they seem to work better for me than the new ones do. The new ones seem to leak in no time.
