Kubota SVL 65 / 75 / 97 Hydraulic Return Filter Replacement 250hr service, I did not drain the tank.

The hydraulic return filter needs to be replaced after the first 250 hours, and then every 500 hours thereafter. Kubota SVL 65 / 75 / 97 Hydraulic Return Filter Service
I choose to change the filter with the fluid in the tank, my fluid only had 250 hours of use and still real clear. I would not recommend doing what I did if your fluid is NOT clear. Overall changing the hydraulic return filter took less than an hour. I would like to mention, have the serial number of your machine with you and make sure the parts counter is pulling the correct filters for your equipment. I was originally sold the wrong filter and I noticed the difference, so I had to stop what I was doing on a Saturday and wait till Monday morning for the dealer to open to obtain the correct filter.
Thanks for watching, I know that this video can be boring because the filter is hidden within the tank, but it does gives a person a good preceptive if you decide to change the filter yourself.

For other viewers: Just pop the 4 visible bolts out, unhook the two hoses, don't drain the tank until 1,000 hours, then you need 12mm on about two extensions to loosen but don't completely unthread the two bolts holding the filter that's down under a few inches of fluid, can use long sleeve glove while in there although hydro oil isn't as toxic as used motor oil. Filter wrench to remove filter, then reverse process making sure to (if it fell in the tank) fish out the 8" or so o ring that seals the cover, install it during reassembly.

@galehess6676 great run down. Thanks!

What size socket and drive did you use to tighten that filter?

[@SiestaSundance]

Great question, I should have noted that! Of course, I bought the new filter, and then I made sure I had the socket. Oh jeeze, this was such a boring video, lol. I will check my box, I only have a few really big sockets from doing front wheel hubs and see if I remember which size.

[@twaggs6523]

I wonder if some of the contaminants that the filter trapped had an opportunity to wash back into the tank while it was being removed?

[@SiestaSundance]

First of all, thanks for watching and comments.
Doubtful, once particles/debris get embedded into the filter, it's designed to trap it. I spoke to a senior mechanic at one of the dealerships, and he said that he does Not drain the reservoir.
The filter was pretty damn clean, and IMO, it probably didn't need to change, but I'm guessing Kubota wants to cash in on servicing, that would probably cost you atleast $500 to have them change it. Everything, of course, is based on machine use. I'm located in a very dusty environment, so I will continue to change the $70 hydraulic filter under the cab every 250 hours. I'm not gonna change that return filter again until the machine hits 1k hours.

[@philweber9172]

Any reason you could not change the other filter also like this?

[@SiestaSundance]

The other filter is replaced at 1k hours, same interval to change out oil.
