Underneath fuel filter on 1023/1025

[RalphVa]

Anyone replaced their underneath, in-line fuel filter on their 1023 or 1025?

Anyone know why JD put this fuel filter there? My 4010 only had the in-glass fuel filter similar to the one that is downstream of the in-line fuel filter on the 1025. Never had a fuel filter plugging problem.

I'm leary of this in-line thing plugging in the winter and not being able to get underneath there in the cold and all to replace it.

I'm thinking of getting a new filter, poking a hole all the way through it and putting it in place or maybe just putting a spud piece of steel line in there. Really question the need for such a cheapy, ill-placed filter.

The filter on the engine is rated to 19 microns, the filter under the floorboard is rated to 8 microns.

Question is, can the fuel system (injectors and injector pump) handle dirt / debris that is 19 microns?

That is weird. I'd better read up on this. Thanks for the headsup, Ralph. Obviously I haven't done my one year fuel filter replacement yet. Bowl still looks good - no gunk on bottom, no separated water either. I am very careful with my fuel - use plastic jug, keep closed so does not absorb moisture from the air, keep tractor fuel tank full (also plastic).

Normally the coarse filter is first in the fuel flow stream, then the fine filter is just before the injection pump. 19 microns is mighty coarse for a fuel injection pump. More like 5 microns or less is the norm for fuel filtration for injection componentry.

Sidenote: PsRumors - what did you come up with for stiffer seat springs? It is well known the stock springs bottom out for most of us. thx.

 

[RalphVa]

Can you get to the in-line filter by removing the left floor panel rather than going underneath?

If it's stuck in the snow or even out in the cold in the winter, going underneath and all is not something I'd really like to be doing. Getting at the in-glass filter is no problem.

I had springs custom made. They are direct replacement and add about 23% more capacity. People have reported great results as has my butt.

Have not looked yet. I suspect the Operator floor is a one piece molded deal that doesn't allow access.

You could but it would be difficult. Look here for the steps to get the floorboard off http://www.tractorbynet.com/forums/...1-1025r-diverter-valve-install-hydraulic.html

Tomorrow, I'm off to do some volunteer work at the extension office, and the JD place is on the way.

So, I'll pick up the 2 fuel filters and hydraulic filter and some lo vis hydraulic fluid to do the 20 hr service (just hydraulic oil; engine oil and FWD oil aren't until 200 hours). Gonna then see if I can get an in-line fuel shut off switch. That business of clamping a line between the tank and the in-line fuel filter is absolutely silly. One of the in-line valves like I put on a push lawn mower once should do the trick and probably less than $2. Just having to replace an in-line filter on a $15,000 tractor is silly, too. should be something better to not require you to mess with clamps and all. Removing rubber lines in colder weather is not a good thing to have to do. I'll probably wait for warmer weather to do that stupid in-line filter.

I agree, Ralph. If you think of it, ask them why a finer micron rated filter is before the coarser fuel injection pump filter too.

 

[Henri88]

Ralph, did JD change the first service at 20hr on the 1000 series? It use to be at 50hr.

 

[PsRumors]

I agree, Ralph. If you think of it, ask them why a finer micron rated filter is before the coarser fuel injection pump filter too.

My bet, if they are like the ones around here, the parts guys will not even know the.micron rating of the filters much less why the configuration.

 

[DeereMann]

Time to change the fuel filters @ 200 hours :irked:.

I was on Deere's online parts catalogue & read about the small pre-fuel filter. The stated purpose for the small micron fuel filter ahead of the main engine fuel filter was to prevent water from passing through.

Well, it must also filter particulates? If so, why not put just one LARGE fuel filter on with a small micron rating? This sure looks like a kluge.

I am guessing the big 19 micron filter comes with the Yanmar engine (maybe the Japanese take better care of their fuel, don't have water in it? Temperate climate?), so Deere's 'solution' was to add the cheap, dinky filter ahead of that you have to change all the time?

Ralph is right - they couldn't have stuffed it in a more difficult access location, either. I will drop the mower deck, pull the LR wheel & give it a try.

*(@$(&* engineers! (I should know, I am one).

I'd think it was there more to protect the small fuel pump from fuel tank debris that is next in the fuel line.

Good luck with the change.

Good point - I forgot about the fuel pump. Seems the critical filter to change regularly (due to upstream importance & small capacity) is the most difficult to get to. Good thing the filter cartridge is cheap.

In fact, I see no functional reason at all for the on-engine filter. I bet it comes stock with the Yanmar engine. But it still needs to be changed, since the element is coated paper that will biodegrade over time - though it likely does no filtering.

I'll have at it when I convert from MMM to FSB later....hopefully it doesn't snow soon.

Mistyped on the "20 hour" service. It's still 50. Did it, without cleaning the suction screen and recently did the engine oil at one year by suctioning out the oil. (Checked suctioning on the 4010. Took it ALL out; nothing came out when I removed the drain plug.) Didn't bother checking the drain plug on the 1025.

Waiting for 100 or 200 hours (whatever the book says) to change out that little beast of a filter off the fuel tank.

Ralph,

Not that it matters that much, but the suction screen on my 1026R had quite a bit of metal particles on it @ 50 hour service interval. I washed them off in the drain hydraulic oil, taking care not to let any oil get inside the screen.

The screen wasn't clogged by any means, but I felt better cleaning it.

I recently did the 200 hour service, and there were no visible particles on the suction screen. I doubt it will ever need cleaning again, unless an internal machine element starts failing.

for what it's worth..........

 

[beenthere]

Are we still talking fuel filters here? I get the feeling when reading that we've switched to the hydraulic oil screen. Just wondering...

 

[DeereMann]

yeah, threads tend to wander to similar-to stuff. This is all related to the 50 hour recommended maintenance. We've established the small pre-fuel filter is critical to change at a regular interval, and it is a PITA to do so. But we carry on! :salute:

 

[DeereMann]

Ralph,

I took the plunge this weekend and changed fuel filters. I also found Deere put the fuel transfer pump inbetween the little 5 micron fuel filter and the large 20 micron (?) fuel filter. The larger filter is mounted on the 'fire wall' in the engine compartment.

It was terrible to replace the little filter - it is between 2 short fuel line pieces, and I took a #2 shower. I thought to move the thing past the coarse filter, but then the fuel pump wouldn't get any filtering or water removal protection.

And I know they must get dirty from summer dust getting into the fuel cap vent over time.

You have any ideas?

P.S. - 12.5 inches of snow up here on Monday. And wind. And way below average temperature.

 

[RalphVa]

I only have about 85 hours. Waiting for 200 hours before tackling that little beast.

Checked at JD dealer about getting an in-line shutoff valve, to put in the line when I replace the filter, to make the job easier the next time. They were out of them. Will ask again later.

I plan to siphon the fuel out of the tank when I do the fuel filter.
