Yanmar 3100

[cowboy357]

Hi rhett & Thanks again for the links & info . After checking it out more I have other Problems I need to adress first. if anyone can help it would be much appreciated.

First off , Thanks California It was exactlly as You described, it was broke in 3 pieces , I stuck a screw in there for a test drive & i,ll get the right rollpin because mine dont fit quite right.

He Said it had No leaks, I can see why the front differental was dry . Leaking around the bottom of the steering Knuckles on both sides . It hasn,t been serviced or greased for years. so after replacing some grease zerts it Steers pretty good . Where the Hydraulic fluid goes is milky white & low . so i filled it also just for a quick test drive .

Sorry . but My main question is when I drove it to check it out for other problems all seemed to be Pretty good But the Milky white fluid came out from what seems to be vent tubes on both sides top of the differtial under the seat . What appears to be Whats left of the hoses I,m assuming is how the Moisture or water got in.

can Anyone tell Me how or where there suposed to be routed ? From one side to the other because nothing is obvious other then that .

The PTO works fine, & no leaking from the rear other then where its coming out from I think is the vent hoses & I,ll drain it completlly & flush it as needed as I Doubt its been run much like this & came from Him doing a quick power wash on it .

Its just going to be Used by the Wife around the garden & yard
& I want all issues to be fixed before She gets on it . So any info, pics whatever would be of great help . I do all the work Myself but need Guidence in whats goes where at Least untill I get a manual. Thanks again to all. Bob

Just a WAG, tell me if I guessed right, but on my next larger size Yanmar those two hoses vent the brake drum enclosures. They end under the seat cushion because that's how deep the Japanese rice farmers submerge these things. On mine the tranmission is vented by an 'inverted J' pipe that comes up out of the top of the differential housing near the back of the seat. As I said, I have no idea if my description is relevant to your model.

Have you discovered the exploded parts diagrams on HoyeTractor.com? Those can help show how things fit together.

Thanks again for the link. The vents I,m speaking of very well could be what you say. But both appear to have a rotted off hose on the top only sticking up a inch at the most.

Thats where the fluid is Shooting out of while Driving. I,m thinking They may Just suposed to connect to each other to keep the Moisture out & Vent through the trans tube You talk about. Does that Make sense ? I,m Also guessing He shot the Preasure washer directlly in them causing the milky white fluid . Thanks again I,ll study that link . Bob

The brake enclosures are sealed aside from those air vents, on mine. This keeps transmission oil off the brake parts.

I don't think you need to replace the rotted hoses, assuming you don't intend to go in water deep enough to reach the top of those tubes.

If your brakes work properly, then I think you are correct that he simply shot the pressure washer in there which is harmless. If you are fanatical you might pull the brake covers and look around. I wouldn't bother, myself.

Hmmm... If there is water in the front axle and water in the brake enclosures, maybe you got a Katrina underwater tractor. Is there any chance of that?

Anythings possible I recon California . But Theres no Moisture in the front axle. just the rear. I Only noticed the milky fluid when I checked it. but when i took it on a small test run The Fluid shot out of those 2 vent holes where the hoses appear to be broke off.

Now I couldn,t find a dipstick to check the level I Could have probablly filled it to full but I kept it below the plug level by an inch or so.

I Just took a few pics to Show the tubes I,m describing , but i,m not sure you can Make it out. as well as both sides of where the front axle is leaking . the first 2 pics the hoses I,m talkin about are about in the middle on the lower edge Right against the red fender . the last 2 are where the front axle has a little play & leaking pretty bad . Thanks Bob

Here's the exploded diagram for mine on Hoye's site. ( I don't see a diagram for yours). In the diagram #49 is the vent hose and #41 is a fitting to attach the hose to the brake housing. Is yours like this? If so, it should be a dry brake enclosure with that vent hose as the only opening.

They appear to be in the same location but thats where the fluid comes out. heres 4 more pics that will hopefully show them.

They are Right against the inside of fender . & just to the right of the bolt thats covered with the milky fluid the other side is the same as well . Sorry But I,m not goos at takin picks or explaining things very well. But I sure do apreciate Your time. & thanks again . Bob

Bob, hopefully somebody will show up who has that model and can give better advice than my WAG's.

I wish I knew more about that model. All I know is yours and mine were made about the same time, so I expect they have similar designs. Beyond that, you need somebody who knows what he is talking about.
