Fast transmission Flushing

[figjam]

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!

Now that is a really cool idea. Dusty

Yep very efficient idea but I hope you shut her down before the stand pipe sucked air or you cavitated the pump. 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. 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.

Very cool tip! Thanks for sharing.

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.

Might just be air but I think if its a milky colour it could be water.

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!
