Greetings, I have heard two mediums used for flushing hydraulic systems on tractor: Diesel oil and kerosene. Which have you used?
Diesel is what I'm planing to use. Richard

Kerosene is supposed to be better/cleaner than diesel - no surprise there. Given the cost of kero these days, it might actually be cheaper just to use the lightest viscosity hydraulic fluid you can find, though. I'm going to use diesel when I do mine next week, since I'm cheap.

We have always used diesel to flush out the hydraulics,and it works well.The goal is to get the gunk out.Make sure to replace your filters once you are done with the flush,we use AW032 wt.hydraulic oil. Tommy Affordable Tractor Sales "Your Jinma parts Superstore" www.affordabletractorsalesco.com |

I flushed the system today I was surprised at the color of the deisel when it came out, black and dirty looking. I was also surprise how little was in the suction strainer. I think the operation was successful. The fittings on four lines coming from the FEL to the valve now leak freely at the valve

If those fittings didn't leak before Richard, they may be leaking now becuase something in the diesel flushing process deterioriated the seals. I think those fittings are the O-ring face seal type - maybe the o-rings deteriorated?

Rich, NO, They leaked before. I think the system now is scrubbed and the fluid doesn't carry with it any of the old thicker oil and debris. The ones that leak are the 90 degree swivels. The cleaner low viscous has less problem coming out. Richard

Any one here have water in the gear box when they change fluids??
I just bought a ft 404, frozen water in the gear box.

No water here. I think the problem is a result of non usage for a period of years. I think you said that tractor sat out in the open for 3 -4 years is that right? Condensation of moisture inside the gearbox adds up quicker than you might think. What keeps that from happening is frequent usage to heat up and evaporate the water. Or simply storing the tractor in a covered structure.
But then again you said there was no water in the engine oil when you drained it. So that makes me wonder if there is some sort or opening that allowed rain over the years to seep into the gear box.

The tractor was suppose to have been damaged last spring when a storm took out 2 trees that fell on it. Hour meter was misread at 105 hours, upon pulling the instrument cluster it was reading 195 hours, no big deal to me. Tractor only sat unused thru the summer & I bought it this fall. It was a very wet & rainy summer. I believe the water got into the unit thru the shifters, bad boots. I am guessing that I got 1+ quart of oil & 2+quarts of water out of it. Put 8 gallons of diesel in & found a leak at the drive shaft, drained it for now. Will have to figure out how to open that up & see what needs replaced, O-ring or seal.
Stay warm

Pulled the drive shaft. Splines were dirty, wet, rusty. The rear seal was bad in one little spot so I think that is were the oil went. Some of the o-rings were missing from the housing. Started cleaning the parts & getting ready to reassemble with new seal & o-rings. How do you guys filter your diesel that is used to flush the system so it can be reused. Did you build something with a motor & spin on filter?  ? |
