I'm needing to do this on my RC72-B mower (same gearbox design from what I can tell) and don't see how this is possible with snap ring #150 still in place. I'll report back, hopefully later today

If it were mine, I would loosen the belt and position it so I could spin each blade at a time without any interference from the belt. If the center spindle makes more noise than the other two I would feel relatively confident a bearing was bad. However, even if they all sound the same it COULD...

Good morning, Yesterday I obtained a RC72-B for my B2150. The driveshaft seems pretty short compared to photos I see online of a new one (Part number: k5671-32010). The female end is pretty chewed up on the inside, which is quite surprising considering the otherwise excellent condition of the...

As an update to this, I obtained a new Kubota head gasket and torqued everything down, set the valves, etc. Before installing the intake and exhaust manifolds, and the glow plugs wanted to spin the engine over to get everything oiled. Coolant shot out of both the intake and exhaust ports, and...

Because I lost the gamble on using the Chinese knockoff rings that came with my Kumar Bros. rebuild kit, and every cylinder is now scored. Therefore, I get to split the tractor again so I can rehone the cylinders without contaminating the main bearings. I was very careful with gapping the...

Yes, I did do all of that. Head is still flat, too. Thankfully my Chinese knock-off starter doesn't have as much giddy-up-and-go and the offending cylinder must have been near the top of its stroke so the engine didn't have much momentum when it hit.

Pulled the head last night. Sure enough, gasket bad between 3&4, who knows where else. $115 + tax for a Kubota gasket. Also, I get to rering the engine at over $100 per cylinder for Kubota rings. Absolutely outrageous what parts cost for these tractors.

Is this the head you need? 15371-03040 Coleman Equipment, the Kubota dealer near me, has two listings for that part number, one is only $837.09. That is for a B7100B-P, and the B7100HSD-D for whatever that's worth.

Number three was wet, precombustion chamber soaked as well. Of course with the diesel that has come out of the lines as I removed them, everything smells like diesel now. It certainly doesn't look like bright green coolant, but it would be coolant in a precombustion chamber. By far the cleanest...

Will do, thanks for the advice.

I hope you're right, pulling injectors is a cake walk compared to other tasks. By the time I remove enough parts to pull all the glow plugs, it's not much more work to pull the head. Would a dirty injector possibly cause this? I had brand new caps over each injector and the delivery valves...

That certainly makes sense, I just wasn't sure what you meant. I just pushed it in the garage and stopped for the day. Thankfully feeling much better today, so perhaps will dive into this more after the kids go to bed.

Everything was prelubed, even cranked some before putting in the glow plugs. I was able to move the tractor, I had the clutch pushed in and in neutral, so not sure what you mean. Still feeling under the weather so haven't had the motivation this evening to start working on it. It's a pain to...

That's the plan. I won't be surprised if that the issue, but with all the fuel I was smelling as it blew white smoke - and no smell of coolant, which unfortunately as of late I am nearly an expert - I'm not betting on it being coolant, either. I think I want it to be coolant. Side note, fuel...

B2150 with V1200-5B engine I have a possible hydrolock on my hands. Yesterday I started my tractor, let it warm up a little at a high idle, then went to hook up to my 3-pt finish mower. Noticed the tach was jumping around weird, needle went way past max RPM (engine did not), but hour meter...
