Just some general info and notes for others. Mine is USA spec, open station NX4510 HST, but I think the whole NX family uses same parts & capacities...
Replaced 5 filters:
Wix WL10113 - $39 + $7 freight since they had to order - O'Reilly auto parts. Originally ordered from NAPA online, but after 2 weeks no shipment, no order update so cancelled online order and stopped by O'Reilly since they carry Wix as well. Uncommon and was in stock at their warehouse in Nashville, TN. Took 48 hrs to arrive at local store. Not sure why they charge extra $7 freight since you'd assume other parts have to get trucked from distribution center to store anyway....
Wix 51324 - $9. O'Reilly auto parts. Same - originally ordered online from Napa and cancelled. Was in stock at local O'Reilly.
Baldwin BT9464 - $27. ebay seller "truck-trailer-direct"
Donaldson P827653 - $19. ebay seller "crossfilters"
Kioti/Daedong F6800-16411 - $66. ebay seller "greenestractorcompanyllcparts"
Replaced engine, transmission, and front axle fluids
Rotella T5 15W-40 - $18/gal. TSC
Kubota SUDT-2 - $104/5 gal. local Kubota dealer
Valvoline 80W-90 - $25/gal. O'reilly auto parts
Otherwise just grease and common shop tools, rags, funnels, catch pan, etc. were needed. Only "special tool" needed was a "vise grip style" oil filter wrench. They must have an 800lb gorilla at the factory tightening down the big hydraulic filter, but I couldn't budge it with a typical filter wrench and it has a round smooth end so a filter socket like you'd possibly use on your vehicle doesn't work.
Just the owner's manual was a good enough reference, but leaves much to be desired. The drain plug bolts all had red heads so were easy to spot and the manual pointed out a general location to find them. Some like the lower drains for the front axle oil weren't called out in manual, but easy enough to see.
I realize capacities vs actual amounts of fluid will have variation due to filters, cylinders, lines, and pans not 100% draining out, etc. But this is what I found refilling everything to "full" marks, running for a while, then rechecking and adjusting to "full" if needed.
Engine oil - 1.4 gal capacity (5.6 qt) - needed 7 quarts
Hydraulic oil - 14.5 gal capacity - needed slightly under 10 gal
Front axle oil - 1.9 gal capacity (7.6 qt) - needed 6 quarts
For 50 hr service, I would not recommend replacing air filter as I did. Factory one was pretty clean and just blowing out with compressed air made it look almost new. Have a spare now or one less thing to buy next time, but wasn't needed. 50 hr service doesn't call for replacing hydraulic fluid, but wanted to for peace of mind. After switching from the Chevron (forget specific flavor, but Chevron brand) dealer used to Kubota SUDT-2 ..... I noticed nothing. In my last machine I noticed a decrease in HST whine after switching. But I didn't have whine in this machine to begin with. So sounds the same. Loader seems to lift the same, move at same speed, move with same smoothness. Driving, braking, everything - no perceptible difference in any way with the fluid swap. I have peace of mind knowing I put a good fluid in it and future service intervals will be far enough apart for me that I really don't care about spending a little more to continue using it. Fuel filter also isn't called out for replacement until 200 hr service. Figured "might as well..." but in hindsight was waste of $. Got no water out of it and as large as it is, no reason it couldn't have gone 200 hrs and been just fine.
Other than cleaning and greasing, everything else for the 50 hr service was mostly an inspection. Belts, brakes, fasteners, etc - nothing needed adjusting, just checked. I did find where the hydraulic lines run under the floor pan (right by the HST pedals) they were rubbing on the metal lip and wearing so fixed that. I read that here and checked right after I got it and they weren't rubbing, so must move a little with use to where they rub in that spot. Was glad to see all the loader frame and wheel lug bolts were nice and snug. Found several lug nuts - esp at front tires - loose enough to decompress the lock washer around 10 hrs and checked torques on everything then. Since that time everything stayed tight. In all, probably took about 4.5 hrs which included time to give it a good cleaning with pressure washer prior to starting any work (low pressure electric one, wide setting).
Otherwise installed some LED light pods and a mount high on the ROPS for those but will have to rewire - either have a short or 3 pods are too much for the 5amp fuse/existing work light pigtail. Didn't realize it blew fuse until after I got it back out to my remote property and don't feel like messing with it out there, so project for another time. Relocated the SMV sign and bolted a 50cal ammo can behind seat for a storage box. Reworked the hanger for the top link to accommodate the fatter hydraulic toplink so it holds it up without scratching it all up now.
