Oil & Fuel HST & Hyd oil filter change

[Carl Bert]

My service manual says to change the Hyd & HST oil filters at 50 hrs but not to change the hyd fluid until 400 hours. My question is, how do you change the filters without draining the oil. Or do you have to drain the fluid, replace the filters and then put the old fluid back in? If thats the case then I might as well use new fluid. Ok I am sitting in my driveway waiting for a response. Thanks

The manual on our L5030 indicates to drain the fluid, change filters and then put the oil back in. My son was helping me and he just swapped the filters out with the oil in place and only lost about a quart of fluid. We did not want to go through draining and replacing. It worked out fine for us; don't know about the B, but it shouldn't be much different.

The dealer said they do it the way we did.

On my L3400HST I lost less than a Quart of fluid total, by having my wife hold a vacuum cleaner to the filler port neck to pull a partial vacuum on the system to help prevent fluid from gushing out . Dont know if it really worked or not, but really very little fluid was lost when changing the hst and hydraulic filters. Others have said park on a steep slope sideways with the intended filter to change upslope and let gravity help with this.

A quick swap of the filters is the concensus of what I have read here over the years. Most have lost minimal fluid with this method.

When I did the 50 hour service on my B2620, I had the replacement filters ready to go-I finished unscrewing the old one with my left hand and had the new one in my right hand. I lost about a quart of SUDT.

Replacing the filter should not result in too much fluid escaping; as others have noted a quart or so. Just make sure you have the new filter ready to go...

So its about a quart for each filter? There is no where, that I can think of, on my property that I can afford to drop 1/2 gallon of fluid. Its either paved, concrete or lawn.

I called my brother in law, he has a transmission shop. I'll go there next week and do it on the lift. I guess I'll change the fluid too, while I'm at it. Thanks for the quick responses guys. :thumbsup:

Hey TripleR, how you doing? Glad to see you switched back to your old avitar pic. Always nice when that pic pops up in a discussion.

Must be nice having kids old enough to help out. My boy is only 8, still some time before I can get him under the tractor.

Oil pan and a couple strategically placed rags...

Changing filters, and when doing fluids for my old Kubota B series, old Farmall-A, and my NH TC40D, I've never had a problem with oil hitting the floor...

Doing very well thanks. I missed the old Avatar too, so went back after trying some others.

Eight is about right to start his apprenticeship. The good things about them at that age is they are low to the ground and have skinny fingers.:laughing:

My sons are 42 and 32, so they sure are a lot of help and more important the older I get. I have turned all the maintenance on the M8540 to my youngest son. My mobility is getting worse, so I will be doing less and less overall.

We lost a total of one quart on the 5030 changing both filters and just put an oil drain pan under it.

Good luck.
