I have an B8200 with a standard, somehow water got in, I think through the gear lever boot. After going through two drums of oil and two drain and refills with no noticeable difference I realized that the hydraulic pump and hydraulics were obviously still contaminated. Even buying cheapo Tractor Supply tran/hyd oil at 35 bucks per I didn't want to run too many more through. So I got my next drum, 3 pieces of 3/4inch pvc pipe and a couple of elbows.



I removed the oil intake pipe, the pvc pipe fitted perfectly into the rubber connector, and put the pvc pipe directly into the next 5 gal oil drum then started her up. Of course I a had a bucket under the drain.




It took about 4 gallons of oil before it started to clean up so I can't imagine how many gallons I would have used just draining and refilling and it sucked it all through in about a minute!

Hope this helps someone!

Yep very efficient idea but I hope you shut her down before the stand pipe sucked air or you cavitated the pump. :rolleyes: That's why the hydraulic designers alway mount the reservoir above or level with case drain. Now we know a Gator did bite the suction screen. :D Welcome to the Forum ;)

Thank you to this post. I just did the same thing but I used a hose and a large funnel. Worked great and seems to of solved my milky fluid problem.

Gainesville, GA,
cool idea. I've noticed while running my b1750 geared 2wd, it have a little frothy trans. fluid on my trans. dip stick. Does this mean I've got a little water in the fluid? It's not much. i keep tractor in barn always unless in use.
thanks.

You are a genius. I have already changed my fluid about 4 times in the past year tring to dewater. I also think it came in through the gear shift boot. I park it inside now. Thanks for the help.

Dragging up an old post...

My L185 has the milky/peanut butter transmission oil problem similar to what is described here...

I was curious on this technique since there would be air in the pipe (assuming that it was not filled/primed somehow). How would the pump suck the oil out of the bucket if the bucket is below the pump and there is air in the pipe?

I can see it working if the bucket is above feeding into the inlet (through a funnel sort of).

What are y'alls opinions of how to flush the pump easily using a sacrificial 5 gallons of oil? How to avoid cavitation/losing prime of the pump?

Or is it nothing to worry about?

Great idea! How can I use this on a L4310?

In general -
Locate where your pump is. They are generally on the right side of tractor (when you are sitting on tractor), and at the rear of the engine.

On yours, I believe you will see the filter for the hydraulic system and there will be a tube running toward the pump. Between the tube and pump will be a short section of hose.

You would be connecting into something that goes into the pump.

figjam,, I assume you were working the 3ph and fel while you were flushing?? Helps to get that fluid out of the cylinders too. Good idea, I have a 3ph backhoe that I need to do that to. Thanks for shareing.
Russell, allmost all pumps will create a suction with air. Some will lift from inches, some from many feet.

Love the idea! I also have the same problem on a L245dt. Does anyone know if this will flush the trans and diff? Also not looking at many drain and fills at 35 bucks a pail!
