50 hour service

SCB · Apr 6, 2004

Bird, It seems to me that I read a post or two awhile back that stated that the posters were finding small amounts of of filings on the first change. What about all you others out there. Anyone find such things?

I found a small amount of chips in the strainer at the 50 hour change. /forums/images/graemlins/frown.gif

After the 50 hour change I don't think another one is called for until 200 hours. /forums/images/graemlins/smile.gif

or should I just wait till I get to 100

I think you should start a thread on waiting until 100 hr's to change your hydro oil. /forums/images/graemlins/crazy.gif

It should get about as many responses as Henro's drilling the ROP's thread. /forums/images/graemlins/grin.gif

You might want to add the Super UDT, UDT debate to the thread. /forums/images/graemlins/tongue.gif

Junkman said: I have been sitting on the fence deciding if it is actually necessary to change the hydro oil at 50 or should I just wait till I get to 100. 

Junkman, I can help with this decision...

I have noticed that the hours on my bx accumulate at about double the rate that they do on my B2910. This is because of the electric hour meter on the bx and the tach-driven hour meter on the B2910.

So in terms of real hours, the 50-hour service I performed on my B2910, was really a 100-hour service if measured in BX-hours.

Since the 100-bx-hour service exactly met Kubota recommendations for my B2910...I see no reason not to wait until the BX hour meter reads 100 to do your 50 hour service.

It is a simple fact that there are linerar-time hours and Kubota tach-driven-time hours. If your manual does not specify which hours to use, you should be free to use KUBOTA tach-driven hours, since the Kubota name is part of that time base.

Yes, SCB, I did find some shavings on the strainers; nowhere close to enough to stop the fluid flow, but maybe a quarter of teaspoonful on the B7100 and a half teaspoonful on the B2710.

( What are the opinions out there and the reasoning behind the opinions. )

I did all the 50 hour service on my tractors between 45 and 50 hours. Now my personal opinion tends to agree with you. The filters and strainers should catch any contaminants and it shouldn't really hurt anything to wait until 100 hours. However . . . , in the unlikely event that you have a warranty problem while the tractor has between 50 and 100 hours, I think there could be (not too likely) a possibility that the manufacturer could deny liability since the 50 hour service wasn't done. So I'd get out there and do it (and of course if I lived where it's as cold as where you live, I might change my mind.) /forums/images/graemlins/wink.gif /forums/images/graemlins/laugh.gif.

( SCB
Bird is right. But after you get all the oil's and filters changed take a hack saw or some other device and open the hyd filter and see if there are any metal shavings in it. There should not be and if the is contact your dealer.
)

There is a tool which is equivalent to a can opener for oil filters.
This dispenses with the hacksaw approach which generates metal
filings of its own and can complicate the inspection. Parker and
others are reported to make such a tool though I've never seen one
myself.

My wife went to pick up the supplies for the 50 hr service since I don't get home from work until after the place closes. I told her to go in there and tell them she wanted everything for the 50 hour service. I told her it would be some filters, engine oil and hydro oil. They only gave her the filters and engine oil. They said the hydro oil didn't need to be changed. I am probably going to do the service this weekend and I guess I will only be changing the filters for now as the dealer is about an hour away.
