Kubota B2650 and B3350 info and hints

Randy,

How does the thumb match up now as compared to before? Had a chance to use it?

thanks,

bumper

Edit: Well, I went an ordered one too! Will report back later

Bumper,
Not that much difference, the bucket is a little lower, 2 inches, and little further back, 2 inches. On the 24 inch bucket , the thumb was already inside the bucket.
Here is a picture with out the adapter, I will take a picture tomorrow with the adapter.

Bumper,
Here is the backhoe with the bxpanded adapter on.

Randy,

Thanks, looks good. I've ordered one with a couple of extra pins as I have a 12, 24, and ripper tooth, so I'll have an unused pin for a future attachment.

With the quick connect I expect to loose a small, maybe unnoticeable amount of force, an equally small additional reach, and a whole lot of time saved switching buckets :c)

Finally got around to checking the hydraulic pressure on my B3350. The WSM says it should be 2400 to 2450 psi. Mine was set at 2050. No wonder the BH77 backhoe was a little anemic. Removed the loader relief valve and it had three shim washers totaling 3.21 mm thickness. I added two washers to add 1.90 mm and that raised the pressure to 2500 psi (close enough for gauge error). While I was at it, I put the test gauge on the power beyond and checked the pressure while operating the hoe, also 2500 psi now, so the loader relief valves must be set higher than that. Anyway, looking forward to removing some tree stumps, should work a lot better now.

Did you notice an appreciable difference?
Tks,

 

[bumperm]

Yes, most definitely, a very obvious difference at the backhoe. No convenient way to quantify but an almost 20% pressure increase, assuming other pressure relief valves are set as high (those on the hoe) is well above seat-of-the-pants detection threshold!

it seems as if all your pictures are deleted ? can u repost them as i want to remove the roof also to do ia custom controll switch layout thansk jim, or send me the pictures direct to r99dutch@optonline.net thanks again

The underside of the roof, showing the three connectors (front and rear light bar, rear camera). Roof is easy to remove - remove three gray plastic caps near center of roof liner (these just snap on to cover 10mm hex head bolts), remove bolts. Next remove all 10mm hex bolts around perimeter of roof, including two that are through extended strap brackets at the rear. Some bolts are much longer than others, no need to keep track of what goes where as the correct bolt length is obvious. Roof is light but ungainly, so you will need two people to remove or replace.

Forgot to mention, when roof is removed is a great time to replace the speakers. Stock speakers are okay, higher quality replacements sound much better, even to my tired old ears. I used these:

Amazon.com: Rockford Fosgate R14X2 Prime 4-Inch Full Range Coaxial Speaker - Set of 2: Car Electronics

though any good 4 inch speaker should do. Note that the old speaker grills were used as the new, more rounded ones had clearance issues with headliner. Could have sanded off offending part, but the old ones fit nicely. Also note that Kubota uses mounting screws into loose nuts on the backside, so it is not possible to remove speakers without access to the backside by removing roof.



The rock was not even visible without front cam, nice to be able to see exactly what loader bucket is doing. That said, the 130 degree fish eye view does take some getting used to.



Rear view with grid lines (lines can be menu deleted), note the 3-point hitch lower links are visible to aid in implement alignment. My 6-O'clock "Messerschmidt twitch" never did work well, so I'm one of those that has to twist my body around to look directly aft. Sometimes this kills the engine if the seat switch is left operational (mine has been jumper wire disabled). So the rear cam is a really nice!







The front mount easily removes w/ no tools and also adjust fore and aft or simply swings back out of harm's way if need be.



Rear cam position. Roof is double wall, hollow, so all wiring was routed inside roof. Butyl rubber tape (caulk) used to seal roof penetrations. One would probably never notice, but cab is not exactly square to tractor, off a few degrees, thus to get rear cam grid lines aligned properly, it was necessary to slightly (0.060") shim one side of cam mount to get it straight.





Pallet forks - I could never see the tips before - - moving rocks is gonna be easy!



When not playing with the tractor.

best,

Lee,

Have you had the most recent software upgrade recall done yet? It was from back in November of 15 I think. In any case, my B3350 originally defaulted to "no auto-regen" at start up. So like you, I was in the habit of pressing the far right button to enable auto-regen (on the fly at more than 2000 rpm). After the last upgrade, that procedure was reversed without telling us. No it defaults (like the newer B3350's) to auto-regen enabled.

You cannot (or at least I cannot) do a parked regen unless the system is asking for one (parked regen light on the panel flashing. Then, if I have difficulty gettng parked regen to start, this has worked for me. Make sure all do-dads are off PTO off etc (my seat switch is bypassed so mine will run with PTO going and me not sitting in there). Shut off tractor, put parking brake on. Put tranny range selector in N position. Re-start and make sure throttle is all the way to idle, push parked regen button. Parked regen light should come on and engine RPM should smoothly go up to 2000 rpm. Go have a cup of coffee or something waiting for the engine to return to idle. During this whole process you cannot do anything to or with the tractor - don't touch the throttle etc.

Note, when it finishes, it it'll keep on running at idle, loading up the DPF again - really stupid. Kubota should have programmed it to shut down by itself after a parked regen- DUH.

I have the same issue as Lee, but mine has a bigger problem. Mine will not even let the tractor crank. Its not auto-regening and if I don't realize the DPF is full (no light) and turn it off, it will inhibit crank. My B3350HU is less than a year old. Been to the dealer twice and they just tell me it need a regen. Is there any official Kubota doc I can take to them to force a repair of the computer?

Help guys.
Randy

Randy,

Is your dealer refusing to help? You might try explaining what's going on again, ask him to talk to the district manager or whatever Kubota calls them. They do have a number they can call for tech help etc.

What year is your tractor? If an earlier one, have they done any software updates?

For those who were asking about all my photos that are no longer in previous threads, sorry I missed that request. I had goofed with the photo filing system and had no good way to go back and fix things. All the photos are available at the following photobucket link - you'll just have to sort through to find what you want (there aren't all that many) - sorry for the confusion.

Bumperm,

The dealer is not helpful. He tries to tell me its my fault. When I forced him to come get it, it started right up and he accused me of running it out of diesel (no way!). They took it in the shop and since it ran for them they just did a parked regen and told me its fine. They brought it back to me in less than 24 hours. I showed them videos of it not working and asked them what to try and they said it might be a interlock. I feel they will do anything to not help me, that is why I need a document or something to show them to fix it. I bought it new from them last June. It was on the lot for a bit (because its an SU model), but is should be a 2015 or 2016. I don't think they know how to reprogram it. It has 66 hours on it and it stopped last time at 33 hours, so I am assuming its the auto-regen causing the no-crank problem. If I can get it to start this afternoon, I will do a parked regen (if I can). The problem is it should be either doing an auto-regen or at least giving me lights or beeps. It does not light up the regen lights or beep at all. One time when It could not start it said Code 21 on the dash, since they could not duplicate it they did not believe me. The next closest dealer is a 45 minute drive and my truck cannot tow this that far.

So I am stuck with my local guy.
