Hi All, I finally got my BX2200 (D905 engine) running again this weekend following a head replacement and working through some valve train issues. It runs the best it has ever run in the time I've had the tractor. Very pleased. However, when running it through the paces this weekend the...

Hey Henro, From what I understand, my 2200 is late in the production run. The timer (which is a black box under the instrument panel) audibly releases the fuel solenoid after around 15 seconds and it passes all the test procedures. The weird wiring to the solenoid (2 wires instead of 3) is...

Yes, fuel cutoff working properly. Two wire solenoid and the timer works as designed. At least some fuel is getting to the injectors, I will investigate further tonight as to whether fuel flow is the issue. I have fuel filters on order; they probably need to be replaced anyway so now is as good...

Good morning, Motion. It was running rough when it was parked, which is what led to the replacement of the head to start with. The fuel is good, as far as I know. I always use Diesel Sta-Bil. It is a bit old but the tractor ran happily until I moved it to the shed. Cylinders were good, and...

Morning all, For those that have been following my BX2200 saga, a quick update. Having moved the reassembled tractor happily under its own power from the garage to the shed, it now won't start. Coughs and sputters and the exhaust smells of partially-burned diesel, but steadfastly refuses to...

Thanks, Lugbolt! New head installed, everything back together. Did a basic "roll test" of the pushrods and found them straight. Started right up with the valves set in the middle of the clearance range. The temp gauge barely comes off the peg, and I was very careful to exercise all the air...

A few updates, all. I found a ready-to-install head new from Kubota for $799 (to me, that's eye-watering but I'm finding out that's what it takes) from GrainFarmer, and my local Kubota shop was able to get me the gaskets and other parts for about 20% less than online list prices, so that's nice...

Well, problem found- several cracks. Center cylinder between exhaust valve and port for fuel injection, forward cylinder two large cracks spanning most of the way from the exhaust valve across the diameter of the cylinder, and rear cylinder no visible cracks. Evidently got hot at some point and...

I'm thinking that's a good possibility. There's a machine shop here in town with the required tools I'll be hauling it to tomorrow. Then to get all the gaskets and stuff on order.

Thank you. I think we have some "expired" dye-pen here at work that is in the "dispose" pile. Can't use it on aircraft but probably no issue for a tractor.

Morning all, thought I'd resurrect this zombie thread now that I've had a chance to get into the engine. First, there was no water in the crankcase. Oil is still cleanish and of the right quantity. Popping the valve cover, there was a waxy buildup on the top of the cover- maybe from...

Thanks, it's definitely parked. The trouble for me at the moment is time to mess with it. Probably will be sitting for a month or so. I'm thinking I should drain the coolant in the meantime?

Evening all, Ran the cap-off test as suggested. Immediately started getting bubbles which very quickly became foam. As the foam broke down after shutdown, it was obviously exhaust soot that was the black particulate. Evidently I have a head or head gasket problem. Hard to invest what Kubota is...

Changed about 3 years ago when I bought it. Went through the big freeze here in Texas so I'm afraid of a crack, but will do the recommended troubleshooting to see what's up.

Will do. Temperature gauge works and it gave no indication of getting hot. Starts normally most of the time, though yesterday it took an unusually long cranking to get it going. Oil is clean and of correct quantity so I know no substantial amount of oil is getting into the water if there is a...

Thanks, RCW. Will do that tonight.

Morning all, Thanks again to all who helped with my BX2200 electrical issues last month- everything works on my tractor for the first time since I've owned it! New problem popped up while running it this week. Was mowing with a finish mower (48" Land Pride) and the tractor bogged down and...

whitetiger, I owe you a round if I'm ever in KS. Thanks very, very much. The 2230 manual matches my tractor precisely. I don't suppose you have a test procedure for the "blinker module" handy? I ran the solenoid and timer tests and both worked as designed, which is great. Inside the wire loom...

Thanks, Dustyx2. SN is 72363, if that matters. Definitely a D905 engine by the tag and the cast number on the block.

Finally had some time to do detailed troubleshooting today. The key witch was a shot in the dark, hoping it would work since I had it on hand. There is no voltage at the solenoid regardless of key position; continuity to ground is fine. In fact, all ground connections on the tractor are good...
