Oil & Fuel 50 Hour Service

[Al Mac]

The B2920 is getting close to the 50 hour service. I thought it would be easy as I would not be the first doing this. Well I searched the "50 hour service" and when reading through the posts it is not as cut and dried as I would have thought. So to the service manual and it only has the engine oil, filter , tran filter, grease. That seems a little slack as the posts were doing more.
So what is normal to do at 50 hours. I will change everything but if that is just being **** I will just do what is needed.

The owner's manual has a chart to tell you what's needed. It's a pretty simple service as you surmised, though you also need to torque wheel nuts/bolts and front loader frame nuts/bolts if you have a front loader (see the separate loader owner's manual for that info).

Change hydro filter only, not fluid, at 50 hrs. There are a few tricks you can use to minimize spills when changing the hydro filter. I like parking the tractor sideways on a hill, with the filter uphill. Barely spilled any.

Do what owners manual says. Engine oil, engine oil filter and one (I think only one) of the hyd filters which on my B only lost the fluid that was in the filter on level ground. I never have torqued any bolts but not saying one shouldn't do it. I guess I would do that before 50 hours if I was going to do it.

I would change the engine oil and filter and only the hydro filters. Don't mess with the fuel filter, air filter or steering fluid. And when you grease, be sure to hit the zerk for the directional pedal. It's also a good time to check the torque of nutz and bolts for looseness and tire air pressure.

I just thought that I would add, don't be surprised to find a lot of machining shavings on the lip of the hydraulic filter. This is absolutely normal. I would say this is the main reason behind the 50hr filter service, as during the manufacture, it doesn't all get cleaned out due to the accessibility to some channels which are cut. Also, to keep from losing too much hydro fluid, I use the house vacuum to pull a little suction on the fill port located near my 3ph. Just be careful, if you suck too much, the wife won't be happy!

Tks for the tips and what is needed. As the timing is good for the 50 hour service, just before WINTER.

Did the 50 hr maintence on L3800 but waited til 100 hrs on hydro filter. It had a magnetic ring with metal shavings attached. checked the FIL big bolts and a couple of them were't tight enough. I also grease loader every ten hrs of use.

I've worked for a Kubota dealer for over 8 years now as the parts & sales manager, some manuals my also say to change your hyd. fluid completely. Not nessecarry until about 250 or next spring. Here is what I reccommend, and pardon me but I have not read all the responses so this may have been said already.

*~Change engine oil & engine oil filter. (Use year round 15/40 or winter weight 10/30) Also change your hydraulic filter (some models have 2 hyd filters a suction & return, the b2920 should only have one) you will probably need a quart of the Kubota UDT fluid to refill what you lose while you change over your hydraulic filter as some may spill. Check that your fuel filter looks good as many fuels get contaminated or dirt/dust may have gotten into the tank during a fill up & made it through to the filter. of course recommended greasing intervals of 8-10 hours. I tell my customers to look and use best judgement. Also always check your outer airfilter this is something that shouldn't be based on "hours" but application, again best judgment & please DO NOT USE A COMPRESSOR TO BLOW THE FILTERS OUT! this tears fibers making them less effective. Then make a habit to check your radiator screen as often as you remember, especially if your doing any brush mowing. Ok! That should set you up for about 200 more hours or through the winter.

- Moreover, some grease joints are subject to more dirt & material than others, no need to waste grease. Also wipe the zerks clean before applying the gun, I see it all the time, zerks get clogged & pressure makes it difficult to release the gun from the fitting. Next I have a customer in handing me 10 broken zerks. It's a cheap part but a pain to tap out & no it's not warranty. forgive me if I missed something or gave more info than you needed, I like to make sure my own customers leave knowing they got their money's worth of information.

I can & I save my customers money, that filter w/ the metal ring, I think it's part #HHTAO-37710, you pay about $20-22.00 for that metal ring @ MSRP IF YOU COMPARE WITH THE PRICE W/O ,teal ring. so when you go to change it, your dealer will automatically sell you the -37710, now most dealers might not even know this & not o e Kubota manual, list, chart or anything will show it crosses to one another. but I've matched so many filters up for people that I've figured out a lot of parts that are the same w/ different #s. SAVE THE MAGNETIC RING & ask your dealer for #HH330-82630 (it could be #HH330-82360? I'm going from memory as I'm at home right now) SAME FILTER NO METAL RING, saves $20+ each change & after 5 or 6 changes you've saved enough to cook hamburgers for all your neighbors & their dogs too.

Is that magnetic ring really needed after the first 50 hours? (break in)

I can confirm this comment. That is why I now use only the shop vac.

For the price of a pail of Kubota Premium or SUDT, I just dump the oil when I change both filters. Cheap insurance and peace of mind for me.

Not to mention I get top dollar trade in when they look at my service records.

Keep the magnet on if at all possible, there is no reason not to have it, you are going to almost always have very fine metal shavings. The HSTs in MY OPINION take more than 50 hours to be fully "wore in." i say wore in, not "broke in". You may have noticed letting off the pedal on a new unit & it comes to a stop quickly vs one w/ 1000hrs.

also pay attention to whats coming off the magnet each time, wipe it off with a paper towl, not rag. You will want to see that there is nothing big enough you could pick out by itself. The filings ive seen just clump together & look like a tiny blob of oil if even that much. And dont panic if there is something a little bigger, just pay attention to what you get. Panic when you have the outer race to a bearing all mangled up on your filter lol. I have seen this to!

To answer the question though, Do you NEED the magnet? No, you dont need it for everything to run just like normal, but if you have it just keep it on, move the magnet from one to the next. If you ask incase you lost yours, forgot to put it back on, or broke it (& the magnets are brittle so be careful) then i would recommend buying the HHTAO filter and getting it back on, but you will likely be ok without.

Simple job.
Much easier than the road rigs we drive. I didn't torque anything yet as I need to get a friends torque handle ( mine went missing years ago).
The oil filter rubber stuck to the block but that happens from time to time.
I didn't notice any metel shavings in the HST filter (I will be checking again) and the new one didn't have the magnetic ring that I could see (HHK70-14070)
If not blowing the air filter out how do I clean it or just replace it. I looked at it and it is still clean so it will be good for some time.

I put magnets in the engine and transmission oil drain plugs on my cars.
Get as much of that stuff as you can out of the oil before it gets recirculated.

Well after looking again I might have changed the wrong filter. Sitting on the tractor the filter under the left foot is the one I changed. The one under the right foot I didn't change. The 50 hours service was to change the Transmission (HST) and the 400 hours is the hydraulics.
Looking at the manual again is making me question which one is the right one.
Question, Are the filters the same, which one is the transmission.
If they are the same, I will just get another filter and change it also.

Al,
I'm replying to your last two posts here, so first I alologize, i should have made it clearer who & what tractors I was referencing on the filter with the magnet, merlynr on pg1, he has an L3800 & mentioned the magnet. Sorry rookie forum boy mistake. And yes, the b series does NOT have a filter w/ magnet.

Next, the HHK70-14070 (some B's have these & some don't) is indeed the HST aka: transmission filter. If you asked your dealer for a 50 hour service kit then they sold you the wrong one. You needed, HH670-37710 which is your HYD. Filter. - essentially your filtering the same fluid just in two different areas, generally HYD filters, filter before getting to the pump, & transmission filters generally filter fluid heading back into the trans case...generally. Hence sometimes they label them "suction" & "return".

Furthermore, I would go ahead and advise changing the correct filter. You will not go wrong in changing them both in the end of matters. I'm sure everyone knows this, but you said your rubber ring stuck to the case upon removal, the factory must not rub the ring w/ a touch of oil before spinning on?? Makes getting off so much easier. I don't know the torque spec on the drain plugs but for my own vehicles I go by my own "spec" - Hand tight + min1/4 max 1/2 turn by wrench. But that can vary upon several things. I hope this clears up some stuff and gives you some guidance.

Good information

 

[McREBEL]

OVRxNxOUt,

I just bought a B2920 with 112 hrs. I do not have the owner's manual yet so can you tell me which side the HST filter is on (sitting on the tractor which foot would it be under)? As I understand it, this is the one that can wait until 200 hrs.?

How do you recommend cleaning the air filter if not using compressed air? Just tap it?

Thanks

 

[Al Mac]

Transmission filter (HST) is changed at 50 , 200,400 hrs under the left foot sitting on tractor.

Hydraulic filter is changed at 400 hrs under the right foot.

The Manual says to blow the filter with under 30 psi from the inside. I am not in a dusty area so I will just replace it as needed.
