    Kubota B6000 Restoration

    I've moved most of the important parts inside my home, with a few still out in my shed. It's mostly the bigger stuff or old hardware I'll replace still sitting outside.

    Kubota B6000 Restoration

    The o-ring on the hydraulic cylinder is in very bad shape. Waitemata Hydraulics didn't have one big enough so I might have to get the genuine replacement part. I contacted the local Kubota dealer before christmas and asked for price and availability for a long list of parts. I haven't heard...

    Kubota B6000 Restoration

    The finished trans cover: I bought a decal sticker pack off eBay here: https://www.ebay.com/itm/324348120712?var=513899544929 The hydraulic cylinder cap. I've been putting a light spray of CRC Zinc It on any steel flange faces. I've used a bit of car body filler (bondo type stuff) to fill...

    Kubota B6000 Restoration

    It's been a while. I've still been active, but mostly prepping and painting parts and doing a bit of disassembly here and there. Nick, I think it will still be some time before I assemble it. The prepping of parts for paint is taking ages and I also need to do some welding and repairs on a few...

    Kubota B6000 Restoration

    I took the alternator apart. I've seen a few different terms used on this forum (e.g. dynamo) but since this is a permanent magnet alternator, I think it is called a magneto. First the fan is taken off with four bolts. The nut on the other side is removed along with a lock washer and conical...

    Kubota B6000 Restoration

    There is a little chip on the four wheel drive engagement thing. I took the diff and bearings out. There was a little play in the left and right side small gears so they may need a shim. I took the first shaft out along with the cover. I'm not sure I can take any more of the trans apart...

    Kubota B6000 Restoration

    Putting magnets in the transmission is a good idea. Hopefully they might just stick on to a drain plug without moving as the surrounding is aluminium. I don't yet know if the rear wheels have tubes yet but it looks like they might. I think the the holes are not too big in the rear wheels so I...

    Kubota B6000 Aux Hydraulics

    It's actually been a while since I used a tractor but I think I remember David Browns being like that. There must be some sort of closed-loop feedback? The B6000 has a valve more like a FEL or backhoe etc. It only has three positions. You can keep it in up or down but it does spring back to the...

    Kubota B6000 Aux Hydraulics

    It sounds like you may have a different type of lever/valve than I've got on the B6000? On the B6000 the lever has neutral (closed), up and down. So it should be in neutral almost all of the time including when switching over if using a single action aux cylinder.

    Kubota B6000 Aux Hydraulics

    Thanks for the pictures! So are you saying that the 3pt actually does hold position when switching to aux? It looks like the cap on the B7200D is almost exactly the same as the one on the B6000, so I wonder if the cap with the valve would be compatible with it. My use case would be for a small...

    Kubota B6000 glow plugs info and upgrade

    These NGK Y-107-1 glow plugs are the old single coil type with no built in temperature regulation. So the resistance doesn't change much depending on heat. I measured one of the glow plugs for at least 30s at around 10.5V and the current/resistance was pretty constant. I'm not wanting to just...

    Kubota B6000 Aux Hydraulics

    That seems like an interesting way of using the aux port with a return. It sounds like you only have a one way valve which would be very easy for me to add, but I think having the 3pt moving at the same time would be a pain if driving a single action auxiliary ram. Any chance you could take a...

    Kubota B6000 Aux Hydraulics

    The Kubota B6000 is capable of controlling auxiliary single action hydraulics with the same lever used for the rear lift arms. This seems like a pretty clean and simple way of adding aux hydraulics to me. Using an integration block or plumbing more valves inline might be more versatile but also...

    Kubota B6000 Restoration

    I removed the flywheel which exposes the rear engine seals. The large one (part 09560-00006) is NOK AH3399F which I believe is 66x88x9mm (I've also seen it listed as 8 or 10mm thick). It looks OK but I wonder if it's still worth replacing as it will be getting a bit old now. The small one (not...

    Kubota B6000 Restoration

    I gave the engine a waterblast. The Aeroclean degreaser I used seemed to work pretty well compared to standard degreaser. It's a bit expensive though. Here are the before and after photos. There's quite a bit of paint coming off the aluminium parts. I might take them off again so I can...

    Kubota B6000 Restoration

    We've had pretty constant rain for the last several days so I haven't been able to do much. It looks like it should clear up by the weekend. Thanks everyone for the kind words, nice to see a couple of others chiming in too. Nick - Most of the flanges I've put back together were bare metal...

    Kubota B6000 wheel/tyre size

    I have a Kubota B6000 4WD that has 4-10 front tyres and 7-14 rear tyres. I'm not sure if they're original. Tractordata.com says the B6000 4WD has 6-12 and 7-16 tyres. it also says the B5000 has 4-10 and 7-14 tyres. I wonder if these rims and tyres could be from a B5000? A lot of the B6000...

    Kubota B6000 glow plugs info and upgrade

    These are the original glow plugs from a B6000. They say Y-107-1, 46 and 10.5V on both of them. They measure 971mΩ and 989mΩ which would make for 10.8 or 10.6A current draw respectively at 10.5V. There are a couple other threads of interest: On this thread there are a few people saying they...

    Kubota B6000 Restoration

    Continued... The main drive shaft has this attachment with a rubber washer in between. There was a whole lot of play. Not sure if it's supposed to be like this? I'm guessing probably not. Haven't read the service manual yet to see if it's mentioned.

    Kubota B6000 Restoration

    Continued... I removed the remains of the damaged tyre from the front rim and wire brushed it. There was actually more rust than I thought. There is a big hole on the inside and more smaller holes that showed up when the rust was brushed off. I know I can fix this but it will be a bit of work...
