Hi everyone,

Well since the nearest dealer to me is 70 miles away I decided to do the 50 hour oil and hydraulic fluid change in my small shop.. What a Pain in the Butt !!!

The oil change wasn't a big deal but the tranny and hydraulic fluid.. HA !!

The problem is that the subframe makes it nearly impossible to get the filters and strainer out.

I have all the necessary tools (except a 26mm socket to get the strainer out, fast Sears trip) so that wasn't a problem. You need a socket because the main sub frame centers right under where you would need to put a Crescent wrench to get to the strainer bolt. I didn't want to strip (being way off center) it so I ran up to Sears and got the socket.

Kubota left virtually no room to remove the filters and strainer because of the subframe. I almost had to bend the strainer trying to get it up and over the subframe. The strainer is almost 8 inches long so you really need room to get it out of the hole before getting it up and over the subframe or you wreck the fine screen filter. It is within a hair of being impossible. Trying to get it back in while not loosing or wrecking the two big O-rings on either side was also a lot of fun.

The filter on the strainer side is also impossible to get out. It is surrounded by pipes and linkage and subframe (and the huge subframe bolts). I ended up taking the brake linkage off and still have to almost bend the linkage out of the way to contort the filter enough to get it up and over the subframe. Down or sideways isn't an option, to many things in the way. Oh, I forgot, trying to get the filter wrench on to remove and then replace the filter.. another HA !! (strap worked best). You would never get a solid filter wrench on and if you did you would never get it off once you busted it loose because of the subframe.

By the time I drained the 4 drain plugs (moving the catch basin for each while it drained), cleaned the strainer, contorted the filters out and re-contorted the new filters back in and then hooked the brake linkage back up it took me the better part of 6 hours to get everything drained, changed and refilled. And that was just for the tranny and hydraulic filters and fluids. The engine oil I did the other day in about an hour.

I called my dealer to see if they knew how to get the filters out without disassembling half the tractor and they didn't have a clue. They said they haven't had a B3200 in for 50 hour service yet. They did ask me to call them with any tricks I might learn from my end !!!

Note.. Kubota really needs to put a little thought into where they put the filters, drain plugs and linkage before they add the subframe next time (or visa-versa). Or at least allow more than an 1/8 of an inch between the unscrewed filter and the subframe. Try turning the filter up and over the subframe with only 1/8 inch clearance with no room down or sideways to maneuver it..and I'm being generous.

So far so good.. no leaks and all is good..

My much older B1550, has similar problem. Rear left wheel and battery needs to be removed so the mudguard can be loosened so a large backhoe bracket can be removed, just so the HST strainer can be removed. Its about a three hour job from set up to pack up.
The strainer was so clogged it was starving the HST.

The other strainer (for the loader and power steering) is behind the loader subframe, so I've never removed it. I doubt its ever been removed. I just blow air backwards into it through the rubber power steering hose before I drain the tranny oil.

These subframe issues are possibly not uncommon (especially with non original equipment) so I would suggest a lot of strainers have never been cleaned, even though the dealers doing the services might have 'implied' that they were.

And I had a similar problem with B7800 and subframe. Had to remove the bar that the clutch pulls in order to get left side filter out. Very snug. I had to loosen the subframe and remove the left wheel to put the three-point hitch sway check widgets on. Just consider it quality time with your baby.

Anyone done their 50 hour service on a B3200 without Back hoe? Are there problems with the non backhoe one? You guys are talking about the subframe for the backhoe, right?

Correct.. the subframe is what gets in the way. Without a subframe it should be a piece of cake (except for the time it takes to move from one drain plug to the next (4 total).

I'm not an engineer but I know enough from working with them over the years to know you can put notches, holes, bends and allowances in steel without weakening it so some of these things can be done without disassembling half the tractor.

I would understand if the subframe and implements were 3rd party units but my FEL, BH and subframe are Kubota products. You would think they would assemble them and test for these problems before shipping them to the field.. but then again maybe I'm just a pragmatist.

Not a problem snuggling up to my B3200, we got to know each other very well yesterday, all the nooks and crannies..:D

At least it will be a while before the next change. For me the 400 hour change is a long way down the road.

Luckily the B3200 only has one strainer.. thank goodness:)
