1998 4400 loader help

[L_Nicholson]

I posted before with problems with my 300x loader cutting down to half speed all of a sudden and so I changed the hydro fluid, filter and cleaned the screen which had very small particles in it. Everything was working great for about 4 hrs after I put everything back together and refilled the fluid and wham.... as soon as I worked the loader on a grade I'm back in the same boat. This time a little worse. The loader won't even function and pull up. There was plenty of fluid after I changed out the filter so this is ruled out.

I'm taking it to the dealer on Monday but thought I'd ask here as well. My opinion is either I'm betting more metal shavings from something inside or I didn't get all the junk out when I drained the fluid the first time. And if I'm getting more shavings where are they coming from....

Also I'm hearing that Deere knows of this problem in this model as there is a manufacturing flaw. Is this something that Deere has a recall on or would stand behind if this was / is the case?


Thanks

Were the particles in the screen metal or rubber? If the seals in the cylinder(s) are deteriorating, you may have to clean the screen more than once to get all the particles out. And that's after you replace the deteriorating seal. I suppose metal shavings would cause the same problem, but I hate to think of something metal creating that many particles.

I had a bad cylinder on my backhoe, and bits of the seal from it plugged up the screen. I cleaned the screen, but it plugged back up again in no time, and my loader behaved as you said. When I got on a slope it was starving for fluid. Power steering got jerky, too.
