YT359C fueling issue

[Kiwibru]

Out baling haylage today and just after making a turn into the next windrow the tractor just died. Tried a restart after zeroing all switches, setting brake, etc. Display comes up, goes through pre-ignition sequence then turn the key...nothing. Wow, weird. No error messages on display. Check three major fuses on engine, all good. Pull steering wheel in lower position remove dash cover to get to fuse bank.
Start checking fuses. Fuel fuse, a red 10 was burned out. Hmmm, could it be the fuel filter? Did a re-install of a new filter at 192 hours, now at 325 hr. So walked back to the farm, grabbed a replacement filter and tortured myself as these filters are not in an easy place to get if you have a FEL! Had to destroy the filter to finally get it off. On too tight! Gory details, I will not go into. Got the new filter on, bled the water separator just for good measure, then ran the pre-start sequence to fill the filter. Tractor started then died. OMG, that same fuse just burned out again! And again, and again. I ran out of #10 fuses. Something else going on here...

Now I am looking at the water separator and guess what the Tech Manual shows? The filtering sequence is Fuel filter / water separator first, then fuel feed pump to secondary fuel filter (the metal canister type) then to supplier pump which feeds common rail and injectors.

So I realize I have a replacement filter element for the water separator / filter but for the life of me I can't figure out how to remove the clear lower portion of the filter!

There is nothing, I mean NOTHING in the manual or the Tech Manual about how to remove the lower clear section and replace the filter element. That filter is first not second in line. Why no mention of that?

I really think this is the issue but I am not wanting to try something stupid like breaking the plastic lower bowl because it won't come off. Special filter wrench? Any of you guys have any feedback on how this critter comes apart?

So the haylage is getting rained on tomorrow, the tractor sits in the field. Sometimes farming is just full of failures and bad timing!
Sorry for such a long story but the details are important.

Antonio replace the 12 volt feed pump that is your issue they are pretty much universal when fuse blows tractor will not turn over this is to save the FIP from running dry and seizing you can get them at several places you should also check fuel for contamination

Could be the pump. Checked on the price, yikes, $197.00. Just hope it is something I can swap out in the field. Fuel is good, pumped from a filtered source, dumped directly into the tank. I have run a B10 blend of biodiesel and that is why I suspected the primary fuel filter / water separator, but your idea got me thinking and that fuse is connected to the lift pump that draws fuel from the tank, through the primary filter / water separator and then to the secondary fuel filter (spin on) then on to the common rail pump to the injectors. Going to have look for any frayed wires too.

Kiwibru, you can search on internet I have seen them from 14.95 to 200.00 there universal 12 volt lift pumps

That might be a viable approach if the configuration is correct, i.e. the bracket, length of wire and connector. Going out at 328 hours is not my idea of a "reliable"
part. No engine, no removal of the FEL loader in the field. So we towed it to a high point in the field that was flat and used another tractor with FEL and some rigging lift straps to remove the FEL off of the YT359. That took 50 minutes. Then 35 minutes to take off the FEL mounting block that is strapped on the engine support rails, then the swap was easy. Then re-assemble after priming the system and start up was checked. We then had to use the other tractor to help lift the FEL into the proper position to then use the YT hydraulics to finish the FEL mounting. Lost six days, and a quarter of the field that was in windrows. Beautiful Kakariki clover stand...now rotted and useless due to ongoing rain. Sometimes farming is a wicked witch. Going to make sure to have a spare pump on hand.

I did manage to find a new back up replacement pump to have on hand. Same PN as the OEM, $39.00 from a U.S. source. Hard to believe the dealers want 6 times that amount for the same pump and configuration. It appears to be used on many brands of Japanese tractors and heavy equipment.
