I'm at 50 hours on my new B2650 HSD the manual says to change the engine oil, engine oil filter and only the HST transmission filter.

The manual shows two drain plugs for the oil change they are on each side of the drive shaft in the manual picture does anyone know what size socket they take and there torque specs? Manual does not show that info.

Also how do you replace the HST transmission filter without losing a lot of fluid? Is there a trick or do you just catch it and pour it back in. I will replace it if it looks dirty.

Where is a good place to buy genuine kubota parts online? Oil and filters etc i did a search and am not sure what places are legit. Please don't say ebay lol

Is there a shop manual for my tractor that goes into more details about the service?

Thanks for the help! :)

I'll answer two of your questions,

believe it or not - unscrewing the old filter will not allow the oil to come out in a big gush, sure it will come out, but once you have the filter seal "broken" then have the new filter ready to go, and the amount you spill will be less than the filter itself!

as for buying true K stuff,

www.messicks.com

and

http://www.colemanequip.com

the biggest problem with both is shipping, but that will always be true. Both have great staff and ship quickly.

To answer on your drain plug. You want it tight :p But just install it with a 1/2" drive ratchet using the standard Lengh handle. Usually the rule is good and tight :D But not bloody ridiculously tight :D One mine, I snug it up till I can't move it anymore by hand and a 12" handle on a ratchet :D probably gives me around 100 to150 ft/lbs. Never actually checked it though.

If it's a smaller plug around a 14 mm, 9/16 wrench, then just use the proper wrench for it. And snug it up by hand.

What ever you do, do not use an impact to install it :rolleyes: Had a couple roll through my shop, that some tater head did that too and rounded the head. Usually requires some strong language, the occasional cursing of the persons first born, a BFH, larger nut and welder, then impact to get the bloody thing back out again :rolleyes: The whole time, your hoping the threads don't give out on the drain hole and the drain pan doesn't catch on fire :p:rolleyes:

Thanks for the quick replies!

I was looking at messicks they seem to have the best website. I find it strange there is two oil plugs. :)

I believe the pans are split in the middle for the propeller shaft. So one plug drains half the pan.

That makes sense the local dealer wants $469 to do the 50 hour service plus another $80 to pick up the tractor.

Even with shipping the cost is only $62 doing it myself.

Now you know what the mark up and labor costs :) figure the filters cost them between 3 and $8 ;)

Kubota Dave. you better check your shop manual again as you should change engine oil and filter along with hst filter and hydraulic filter. The hydraulic filter change you at least need to plug off the vent and have a filter ready to spin on quickly. You can loose alot in a hurry. You should also check all of your belts and hoses to make sure they are tight as well as loader frame bolts if you have one. You should also check the torque of all of the wheel lugs as some of mine were not at spec. As Darren Todd says there are 2 engine oil drain plugs.

I guess that depends on how you read it. Looks like 400 hours to me.

New to the Kubota world but I changed mine and only opened one drain plug. I put in the amount of engine oil the manual calls for and it was correct on the dip stick.

So I wonder, do you really need to remove both plugs. If so I should have had too much oil in the engine but I didn't. And the oil was clean for the usual 10 minutes of run time before it started to look black.

I took both of mine out but i would not worry about it if you only did the one.

What you did was dilute the oil clean with old, or maybe the old with the new.:D

Nothing catastrophic, but you need to know you didn't get it all out! So don't overfill it. And next time don't just remove the other one!!!!;)

I don't see how I could have diluted it.

I removed one plug to drain it, then put in the amount the manual calls for and then had the correct reading on the dipstick.

If there was half the oil still in the pan I should have had too much in the engine.

I'll drain it again and measure the amount that I get from the one plug next chance I get.

Not sure Kubota Dave why our manuals have different specs, but this is what I was going from. I did talk to my dealer when I went there to get oil and filters and his recommendation was engine oil and filters and hst and hydraulic filters as there could metal in the system during break in during the first 50 hrs. Not trying to tell you what to do with your machine, just trying to be helpful and pass on some of my knowledge after operating heavy equipment for 38 years.

You'll get most of the oil out by using the one plug. The issue though, is you don't get all the oil out of the pan if the second plug isn't removed.

My grandfather only removed the one plug on dad's l2250 when he would service it. After several years of this, I happened to change the oil and pulled both plugs. I only got maybe 1/2 quart out the other plug. But what did come out was more sludge and goop, then oil.

I replaced ALL filters, and ALL fluids, even front axle, and obviously removed both plugs on tranny and motor.
I always replace all for that first critical break-in service.
It was about $200 for fluids and filters.
---------
I noticed that different manuals have different recommended service intervals regarding filters and fluids.

I wonder why are manuals say different things? I bought mine in 2015. Are there shop manuals for the B2650, i have seen them for other models.

When i took off the HST filter the fluid looked like new motor oil. I've never seen it new or used so i have no idea of the color it gets over time.

Not sure why our manuals are different . Yes there is a work shop manual for the B2650. I ordered one when I ordered my new 2015 B2650 as I did for my 4 wheeler and my Harley Davidson and every new piece of equipment I get as I do all of my own maintenance for the last 40 years. You will not see the hydraulic oil that you drained out of your new tractor look discolored at 50 hrs. of use. You will also probably not see the metal in the oil either unless you cut open the filter and check or you have alot and see it in the top of the filter. But that does not mean there is not metal in there. That is why in heavy equipment they take oil samples and send to a lab to have it analyzed to see if there is contamination before it becomes an expensive problem. That is why I did the same as DWLG1958 and did all of the recommended 50 hr services plus the front differential to replace all of the oils and filters after the 50 hr break in.

Confused.

As I said Kubota's are new to me but not tractors and mechanics. I read the B2620 and B2650 share the same engine. But they must not share the same oil pan. I only removed on drain plug and it all worked out as I said above.

I was just under the tractor tightening backhoe carriage bolts and noticed the reason removing only one drain plug worked for me. I only have ONE drain plug.
