vent hoses plugged - any solutions ????

[tstex]

Hello to all,

Was changing the oil on my M5400, and noticed those **** dirt/mud daubers had plugged my vent lines. They filled the lines, and other small holes w a white crusty substance.

When i cleared the one that is basically under my seat, I heard pressure escape. Does anyone have a solution for this? Some type of cap w many sm holes would work. Any such thing around?

For all of the other small holes on my tractor, I think I am going to fill them w clear silicone. Anyone see this as a problem? It would seem that once filled and dried, it could easily be removed if required.

Thank you,
tstex

On certain orifices, I've used aluminum window screen after figuring a way to fasten it in place.

don't know about the hose sizes ... perhaps an aquarium air rock ....

air bleed valve fitting for pancake AIR controllers? ( brass with screens on them )

inline fuel filter.

All of the equipment on which I worked on the design we had filtered vents. The fuel tank vent on my new M135 GX was plugged with mud from the time it was delivered. I replaced the vent hose with a more substantial hose and added an in-line filter. Cat's recommendation for a fuel tank filter is 2 micron but I went with a 10 I had handy. At Cat we used 10 micron hydraulic tank vent filters. I do not understand why Kubota wants directly outside air sucked in when the system cools down but then again Cat has a 4,000 hour hydraulic oil change interval and Kubota has a 400.

inline fuel filter.

How is an in line filter going to stop a dirt dauber from plugging the hole of the filter. Maybe filter tip hole is too small for dauber to access? I'll vote for window screen on the hose.

if the hose is long enough ... bolt / golf tee in end ....cut some slits then wrap with screen ....and tie wraps...

Thanks guys, some good ideas...

I have some very fine wire mesh screen that I can fashion to fit the ends. I bought a 4-pak of those sm claps about 5-6 yrs ago thinking they would come in handy one day - they are the adjustable ones you tighten w a screw-diver...should be able to tighten the screen pretty securely. I might have to tie-strap the one that is near the oil-pan area so if it hits tall brush, it will not catch and be pulled off.

Lastly, these are only for air-flow and not any fluids, correct? Just want to make sure if I make a loop, nothing will get caught like a p-trap under the sink.

Thank you guys,

Extend the vents.
I slip a rubber hose over my hydraulic vent and ziptie it on to get the vapors and mist creep down underneath the tractor.
Front axle vent gets an extension up under the engine cowl to keep water and mud out of the axle.
Mud daubers will still find the end hole in the extension, but they stay near the end.
pull the extension hose off the factory vent once in a while and blow it out.

Found a good solution...

Used the metal-type screen for windows. Cut them into 2" strips about 5/8" wide and just twisted them into the ends of the hoses...the ends are sharp and bite nicely into the hose ID. By pushing them 2" in, they are not coming out. Use gloves bc the ends of the screen are SHARP. At the end closest to the hole, you just fashion it where it blocks the hole. The screen is now too much for a dauber to get in, but the porosity of the screen will surely allow ventilation. BINGO !!!

 

[jaotguy]

or use the dollar store scrubbers ( kitchen green mesh rectangular pads ) cut into strips and do the same ....

I like the vents Toyota uses on their truck axles. They have a steel cap with a spring inside pushing a rubber seal. The steel stops anything from going back into the axle/ transmission. The gap around the cap is pretty small so nothing seams to mess with it. If they do stick you just simply twist the cap and free it up. They tend to rust after a number of years of driving on salty New England roads but for a tractor they are fine.

Of course you could use something like this as long as you know water will not be able to get sucked back into the hose.

where are the vents located?

 

[tstex]

I found one under the seat, one under the gas tank, one under the crankcase and another one along the engine side on the right side if you are sitting in the seat...I am not there so I will have to look again. Anyone else w either better eyes or their tractor closeby?

Both my M series tractors are 500 initial and then 1000.

I have used the in tank ones that only have one end on them like this

If the get soaked with water or caked with mud you have to change them. You can also extend the hose and vent them to a spot where you would not have to worries about that
