NX4510HST completed 50 hr service

[CMV]

The Wix and Baldwin together are a good amount less expensive than the Daedong hydraulic filter alone. As large as it is, even if it is somehow inferior to the OEM, it's still going to do a lot... My fluid looked new coming out (probably why they don't call for a change @ 50 hrs in the first place) and there was very little on the plug magnet. Very fine - same as grinding swarf - and a little less than a pea sized amount. Wouldn't be surprised if all that was from trying to find M range

SO here's some pics. The filters themselves and how I label them with a cheapie Brother PTouch label maker, the LED light pods I put up that are either way too much for the 5A fuse and little worklight wires in rear or I have a short blowing that fuse (project for some other time....), how I did the SMV sign, and how much space is left over with a 50cal can behind seat, and my solution for the shoulder bolts w/ nylocks to fold the ROPS.

nice....:thumbsup:

glad to see others as OCD when it comes to filters marked with hours and dates.:cool2:

I just use a sharpie permanent pen, on a white one I use a black pen and on dark filters I use the a silver one.

I used the metallic silver sharpie on last one - i keep handfuls of those around since they are good for marking just about any background color

But the sharpie wore off pretty quick on some of them. Maybe didn't wipe them well enough first or think to write on a less exposed area? Who knows.....so tried the P-touch labels this time which should stay on and legible for the life of the filters. If not, no big deal, not like I'll forget I did the service

Office Depot/Office Max/Staples - one of those places had a good sale on the smaller P-touch label makers not long ago. Under $20. We have a local discount store that sells all sorts of oddball stuff. I think it comes from insurance claims or something, but they have a wide variety and ever-changing inventory of real cheap stuff. I find the tapes for the P-Touch there for just a few bucks. So that's a cheap way for me to mark things and it writes much more neatly than I do ....

I’m going to guess they weren’t clean when you wrote on them, I’ve not had any issues with them coming off even when washing or using cleaning chemicals on the tractor. Only issue is if you get thinner or reducer something of that nature on the filter then it will try and wipe off. The labels should do a fine job of staying on though I would think, I have one but it’s a desk top model so I never have it out in the shop.

Use a paint pen. The ones that have the mixing ball inside. Like junk yards use to write on parts. Oil based and sticks to everything that sharpies won't.

Milwaukee makes a good one.

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.

CMV,

I have the same tractor. Couple things regarding hydraulic and front axle capacity:

Front Axle: I experienced EXACTLY what you are describing with the capacity seeming to be less than listed. After thinking about it longer, I had to remove to upper drain plugs to let the trapped air in the front axle hubs escape. Once I did this, I had to put in 2 extra quarts to get the oil to appear on the dipstick (as expected, it also started seeping from the upper drain plugs at this point).

Hydraulic Oil: The capacity of your HST tractor IS actually 11.9 gallons. Early printings of the owners manual and an old PSB had listed this tractor as having 14.5 gallon capacity. Look at the date on the back cover of your owners manual. Mine shows it was edited and printing in March 2015 and here's what mine states about hydraulic fluid capacity: Page 7-6 and page 3.13 show 11.89 gallons. Page 7-17 shows 14.6 gallons for HST (and the outdated PSB that is available online shows 14.6). I called corporate Kioti on this one and they said the capacity is actually 11.89. This was confirmed when my tractor took 10 gallons of fluid on a change. I think it's safe to assume the extra 1.9 gallons is fluid trapped in cylinders and pumps.

I hope this helps.
