Yesterday I received the rear remote valve and all the associated hardware that I will be installing on my B3030. The picture shows everything that came in the kits (Kub. wholegoods part number B7306 and B7304). Instructions were also included. The parts look to be of very good quality.

B7306 - Base kit and 1st lever
B7304 - Double acting valve section

I don't have any experience with hydraulics but the installation instructions are pretty good and the kits include everything that is needed for an OEM-looking install. I'll snap some pictures along the way and report back. If all goes well I will be using the remote to operate a hydraulic top link - something I don't have yet but have always wanted.

With the B3030/B2630/B3000 no longer being produced, there is no guarantee how much longer these remote kits will be available. So I bought one. There is also a kit for providing a second remote valve that gets stacked on to the first valve but for now I'm just going with the one.

Take plenty of pics. I've been wanting to add both remotes to my 3030 since I bought it. Just haven't justified the expense yet. I've found that everything I've bought from Kubota has been 100% complete down to the last nut / bolt. I'm sure it will be a straightforward install.

I got the remote valve installed without much trouble and it seems to be functioning properly although I won't know for sure until I hook something up to it. I'd like to have a hydraulic top link on my tractor in the next few weeks.

Some notes:

The dealer that ordered the kits for me said I should not have to remove the rear wheel to do this install. That may be true but I went ahead and removed it and I'm glad I did. Having to reach in from behind the tractor would not have gone well for me. Removing the wheel/tire gave me straight-on access to the area I was working on. The only downside was having to get the loaded tire back on the studs.

The instructions say to apply grease to the o-rings that get sandwiched between the three main parts of the valve assembly. The dealer said that any kind of grease will do and the only reason for it is to keep the o-rings from falling away or shifting when putting the pieces together. However, the parts that required o-rings (items 1, 2 and 3 in the first picture) were shipped in plastic wrap and were quite oily. Just the oily film was enough to keep the rings in place.

Bolt the three valve components together, and the whole unit is ready to be mounted to the tractor.

The remote hydraulic ports on the B3030 are capped off in two different spots, shown in the next two pictures. The upper cap is a rectangular plate with one bolt holding it. I removed the plate as well as a rubber plug that the plate was covering. This plugged hole is where the return pipe coming from the valve assembly goes to. The bolt hole is used to accept a long threaded stud that runs through the entire width of the valve assembly. The original bolt, plate and rubber plug are no longer needed.

The other ports are covered with a diamond-shaped cover - held on by two bolts. Underneath is an oblong-shaped o-ring. The bolts, cover and o-ring get removed and are no longer needed. The portion of the valve with the two rounded pipes (item 1 in the previous picture) goes in its place using the kit's bolts and o-rings. These two bolts and the longer threaded stud hold the whole thing in place. The return pipe does not provide any support - it just shoves into the holes on the valve end and the tractor end. Each end gets an o-ring. There was a small amount of fluid loss before I got the assembly mounted - just a few drops on the floor plus whatever else oozed out but never made it to the floor.

The hoses and hose fittings went on next. The two hoses have slightly different lengths and the fittings are also slightly different between the two hose sets.

The couplers mount to a bracket that gets bolted onto the underside of the tool box. Getting the bracket secured was a little cumbersome because I had to reach through the toolbox with my right hand while trying to feed the bolts up though the bottom from around back with my left hand. A second person would have come in handy here.

The quick-disconnect couplers are held into the rounded housing with "Cir-clips". These were difficult for me to get in and may be next to impossible to remove without the proper tool or without scratching the heck out of the housing. I'm sure there is a Cir-clip remover tool out there somewhere.

The new lever guide replaces the blank that was there and has a longer slot on the outer side (valve 2). Apparently, a second remote valve can have the float feature with a forward locking detent position, hence the longer slot. The first valve cannot have float if using these factory kits.

When I started up the tractor and checked for leaks everything was fine. However when I operated the valve I had a serious leak near the tail end of one of the hoses - just before the quick-disconnect. It turns out I forgot to tighten one of the connections beyond finger tight and made a bit of a mess. My suggestion - test everything out under pressure BEFORE securing the quick-disconnects into place with the cir-clips. Fortunately that is what I did and I was able to fully tighten the fitting without having to remove the clips.

The end result is a factory-look remote and lever addition. I was not happy with the price but I went with the kits because they are tailor-made for the B3030 (or B2630 or B3000). The alternative is to try to piece together all the piping and valve parts, most likely mounted somewhere on the exterior of the tractor rather than under the fender. For me it would have meant having a shop do the work for me, plus having someone trailer the tractor to and from the shop. It may have actually turned out cheaper going this route.

I'm now on to shopping for my hydraulic top link.

It is well worth the few extra $$ to buy the kit. It is not just a look alike it IS a factory OEM install. It is the same one that gets put on at the dealer if you ordered the tractor new with it.

Von, you did a superb job of documentation. :thumbsup: Looks great!

Just like the factory!!!!!! A lot better then having a lot of spider legs running all over and cutting into hard lines. How tell us you didn't like doing it. I can tell by the nice write up you enjoyed doing it.

Nice job, Von, what type of quick disconnects are they, do you just push and pull out....
or do you have to hold the back section also,

JJ, I checked your link, I wasn't aware there was such a thing as a "self contained" top link,
no hydraulics needed, those are pretty cool.

The QD's are the push-in/pull-out type - or so I am told. I have yet to use them. The kit included the male ends of the QD's but since no hose is attached I did not want to couple them at this time. On the back of the coupler, the round area is squared off on each side. I presume that is there to accept a wrench in the event that the push/pull method needs a little assistance.
