Slow leak!

[jim76]

Hello Everyone,
First post, I have a 2019 Kubota B2650 with approx. 35 hours. Light mowing only so far. I noticed a small puddle of oil after mowing, maybe 3 or 4 drops.
The oil pan bolts are covered with a film of oil. My question, is the oil pan removal possible without removing the engine? The tractor is slightly over
a year old so no warranty. Thanks guys!

I'd try snugging up the oil pan bolts first, they may have loosened..

I thought the new tractor warranty was at least two years...

Just looked at my warranty and Yes, it's 2 yrs. :thumbsup: Called dealer will pick up by the end of the month.

That's GREAT news on your warranty. I think on most all tractors the oil pan can be removed with out removing the engine. It could be difficult on some but the pan should slide forward or rearward until it can be dropped. Oil pan bolts do not have to be really tight. Radios 1 has the right idea if it was a DIY project.

It could be a faulty front oil seal, in which case it could be a bit more than a quick nip of the sump bolts. At least the agent should sort it, but I would still have a look after giving it a run when it comes back.

Thanks for all of your suggestions. I hope the dealer can fix this leak and that it's not the main seal.

Main seals on Kubota's are about a 20 minute job but that should be warranty too.

I'd suggest a 15 minute run of the engine once a month to keep the seals from drying out, followed by charging the battery, starting the engine drains it..

Not really. The front crank seal on Kubota engines is constantly sprayed with oil splash from the timing gears. It's a synthetic seal with an internal spring tension ring. Won't dry out.

but, it still happens..

From wear, yes, I just replaced one. From sitting, no. Easy to replace seal too. Pull the crank pulley / balancer, slide off the wear sleeve and pop the seal. Install a new one with a seal driver, install a new wear sleeve (oil first) and replace the crank pulley and Woodruff key. 20 minute job, tops. Don't forget to torque the pulley fixing bolt to the torque spec listed in the appropriate WSM.

Hello again,
Got the B2650 back from the dealer. Mowed a 2.5 ac. field, pulled into the shed and noticed it still leaks after $400 delivery fee and 10 day wait.
Decided to do the work myself. Anyone pull the oil pan from a B2650?

I don't have one but... I've heard it's easier to pull the motor to pull the pan on some of the smaller tractors because the clearance between the pan and the frame is real tight. You need to look at the pan relationship to the rails to ascertain if removal from the bottom is feasible. You will have to remove the front propeller shaft and it's shield to gain access to the pan if you do it from the bottom. Are you positive it's the pan leaking and not a faulty install of the front crank seal? I know on my big Kubota's the front crank seal is a 2 piece seal. The outer seal and an inner steel sleeve and they come as a matched set. Think I'd snug up the pan bolts first and see if that curtails the leak. The torque specs for those bolts will be in your owners manual in the bolt torque chart. Both my tractors leak a bit once in a while but they are over 20 years old and worked hard.

Thanks 5030,
The pan is very tight to the frame with welded-on nuts on the inside of the frame.
I think you are right about removing the engine.

Thanks again
