something you should know ,,,,,,,,,,

[rb4410]

just finished the first service on my 4410 E-Hydro.the whole process is pretty straight forward with the engine and trans. however there is something you should know.
in the manual it gives fluid capacities for refilling references.
the engine will take 5 quarts with the filter,,,,,,,no problem, however the manual calls for 6.8 gallons to refill the transmission. that is incorrect information. it takes approx. 7.8
gallons to fill it to the middle of the sight glass as recommended in the manual. so if you are a do it you're selfer, i recommend buying 2-5 gallon buckets of hydro oil when you do this service. it will cost less to purchase the bulk amount of fluid and you will also have enough to service the front axle if you're machine has MFWD, although servicing the front axle is'nt called for at that service interval,you have already committed to draining all of the other fluids so you may as well drain the front axle while you are under there, it won't hurt a thing.
be prepared to spend about 3 hours to service you're machine. be thorough with the grease fittings and all fluid levels and make sure you have a way to contain a large amount of waste fluids and as always, dispose of them in a proper manner. i hope this post is helpful to anyone willing to tackle this chore. i spent approx. $170.00 to do the service myself so if you are inclined to do it yourself you can save a couple of bucks too.
good luck to all ,,,,,,,

Thanks for the info. I just had the 50 hour service done by my dealer. They came to the farm and did it in about an hour.

Total charge was $199. I thought that wasn't too bad.

Glad to have a comparison. My schedule has been very busy and I think it worked for me to pay the extra $30.

I'm a do it yourselfer. I enjoy the work and believe that's the way to avoid more costly repairs by always checking through your equipment and noting what is likely needing replacement, etc. Nonetheless, does JD recommend that you change the transmission/hydraulic fluid at the 50 hr. mark? I'm getting close to 500 hrs. and the owner's manual indicates that I should drain all the hydro fluid, change the external filter and clean the vent and interior screen, etc. I think swapping out the entire trans/hydraulic may be exceptional maintainence but a little over the top, IMHO.

They sure do, it is outlined in the manual! After the first service at 50hrs, the next is at 200 if memory serves me...

It is amazing to see the metal bits that are trapped in the suction screen at the 50hr mark!

Good grief. That seems a little excessive, but sure enough it's in the manual for the 4410:
Break-in - After 1 Hour
NOTE: When machine is new or anytime wheel hardware is loosened, tighten all bolts after one hour of operation and every four hours thereafter until proper torque values are maintained.

· Check wheel bolt torque.

Break-in - After First 50 Hours
· Change engine oil and filter.

· Change transmission oil and filter.

· Clean transmission suction screen.

· Change suction side filter.

· Check alternator belt tension.

· Check radiator hoses and clamps.

· Check air filter intake hoses and clamps.

· Check wheel bolt torque.

· Check tire air pressure.

· Check for loose, missing, or damaged parts.

· Lubricate lower brake pivot tubes.

· MFWD Models: Check front axle oil level.

· Check and clean rockshaft control valve filter.

· Check air restriction indicator. Replace only primary filter unless secondary filter is visibly damaged or indicator shows an air restriction after the primary filter has been changed.


But for the 4120 we just bought it says...

Break-in - After 10 Hours
· Check wheel bolt torque.

Break-in - After 50 Hours
· Change engine oil and filter.

· Check wheel bolt torque.


And so the tranny fluid and filter doesn't get replaced until 400 hours and then every 400 after that.

Every 200 Hours
· Check engine oil and filter.

· Inspect alternator belt.

· Check air restriction indicator light.

· Check wheel bolt torque.

Every 400 Hours
· Change transmission oil and filter.

· Clean transmission suction screen.

· Replace fuel filter.

· Remove air filter and inspect elements.

[agreeing with kennyd],

I may be over the top with maintenance but, I'd rather spend a few extra $'s, and hours, on changing fluids than see the metal filings again that I saw at the 50 hr. mark. I'm at 275 hr. now and have done all services early (just compulsive I guess). I probably spend more time greasing, lubing, and changing fluids than cleaing the surfaces. For me, I'd rather have it keep working than look pretty. My vote is follow or exceed any service recommendations....IMHO.

in response to wesdor's service costs,,,,,,,,,,,,,,not sure what model you have,but i bought all of the hydraulic filters and fluid from the JD dealer,i used a wix filter and drydene oil for the engine. total cost for the hydro fluids and filters used was around $158.00 and then another $17.00 for the engine oil and filter,i just can't picture the dealer coming to you and performing this service for that kind of money on a 4410. the time i spent to do it myself may be a little in excess as i check over everything very thorough. an ounce of preventitive maintenance is worth a pound of gold. and also when i removed the suction screen to clean it i was amazed to see that there was hardley any debris on the screen. i have read other posts describing how much they had found. however i highly recommend following the manual on this issue of changing the fluid as when i emptied the drain pans i was shocked to see the amount of metal filings in the bottom of the pan. well,it's done now and i'm back to work with it and as always it performs great,,,,,,,,,,,,,,,,,,,,,

I too, am pretty conservative about maintaining my equipment and in general, change all my filters and fluids much more frequently than the recommended intervals. And I recognize all too well that clean oil and extra grease are pretty cheap insurance against early failure. As pz21q22 pointed out, evidently the recommended maintainence differs between models. As well, I continue to note a sheen of fine metal filings even when using Mobil 1 synthetic in my Duramax and the wife's Powerstroke at the 3,000 mile changes and they each have just over 30K miles (>10 changes).
